NETDATA

REAL-TIME PERFORMANCE MONITORING, IN THE GREATEST POSSIBLE DETAIL

Drag charts to pan. Shift + wheel on them, to zoom in and out. Double-click on
them, to reset. Hover on them too!

CPU


Total CPU utilization (all cores). 100% here means there is no CPU idle time at
all. You can get per core usage at the CPUs section and per application usage at
the Applications Monitoring section.
Keep an eye on iowait

iowait
(0.0000%). If it is constantly high, your disks are a bottleneck and they slow
your system down.
An important metric worth monitoring, is softirq

softirq
(0.75%). A constantly high percentage of softirq may indicate network driver
issues. The individual metrics can be found in the kernel documentation.

LOAD


Current system load, i.e. the number of processes using CPU or waiting for
system resources (usually CPU and disk). The 3 metrics refer to 1, 5 and 15
minute averages. The system calculates this once every 5 seconds. For more
information check this wikipedia article.
system.load



DISK


Total Disk I/O, for all physical disks. You can get detailed information about
each disk at the Disks section and per application Disk usage at the
Applications Monitoring section. Physical are all the disks that are listed in
/sys/block, but do not exist in /sys/devices/virtual/block.
system.io

Memory paged from/to disk. This is usually the total disk I/O of the system.
system.pgpgio

I/O Pressure Stall Information. Some indicates the share of time in which at
least some tasks are stalled on I/O. In this state the CPU is still doing
productive work. The ratios are tracked as recent trends over 10-, 60-, and
300-second windows.
system.io_some_pressure

The amount of time some processes have been waiting due to I/O congestion.
system.io_some_pressure_stall_time

I/O Pressure Stall Information. Full line indicates the share of time in which
all non-idle tasks are stalled on I/O resource simultaneously. In this state
actual CPU cycles are going to waste, and a workload that spends extended time
in this state is considered to be thrashing. This has severe impact on
performance. The ratios are tracked as recent trends over 10-, 60-, and
300-second windows.
system.io_full_pressure

The amount of time all non-idle processes have been stalled due to I/O
congestion.
system.io_full_pressure_stall_time



RAM


System Random Access Memory (i.e. physical memory) usage.
system.ram

Memory Pressure Stall Information. Some indicates the share of time in which at
least some tasks are stalled on memory. In this state the CPU is still doing
productive work. The ratios are tracked as recent trends over 10-, 60-, and
300-second windows.
system.memory_some_pressure

The amount of time some processes have been waiting due to memory congestion.
system.memory_some_pressure_stall_time

Memory Pressure Stall Information. Full indicates the share of time in which all
non-idle tasks are stalled on memory resource simultaneously. In this state
actual CPU cycles are going to waste, and a workload that spends extended time
in this state is considered to be thrashing. This has severe impact on
performance. The ratios are tracked as recent trends over 10-, 60-, and
300-second windows.
system.memory_full_pressure

The amount of time all non-idle processes have been stalled due to memory
congestion.
system.memory_full_pressure_stall_time



NETWORK


Total bandwidth of all physical network interfaces. This does not include lo,
VPNs, network bridges, IFB devices, bond interfaces, etc. Only the bandwidth of
physical network interfaces is aggregated. Physical are all the network
interfaces that are listed in /proc/net/dev, but do not exist in
/sys/devices/virtual/net.
system.net

Total IP traffic in the system.
system.ip

Total IPv6 Traffic.
system.ipv6



PROCESSES



System processes.

Running - running or ready to run (runnable). Blocked - currently blocked,
waiting for I/O to complete.

system.processes


The number of processes in different states.

Running - Process using the CPU at a particular moment. Sleeping
(uninterruptible) - Process will wake when a waited-upon resource becomes
available or after a time-out occurs during that wait. Mostly used by device
drivers waiting for disk or network I/O. Sleeping (interruptible) - Process is
waiting either for a particular time slot or for a particular event to occur.
Zombie - Process that has completed its execution, released the system
resources, but its entry is not removed from the process table. Usually occurs
in child processes when the parent process still needs to read its child’s exit
status. A process that stays a zombie for a long time is generally an error and

status. A process that stays a zombie for a long time is generally an error and
causes system PID space leak. Stopped - Process is suspended from proceeding
further due to STOP or TSTP signals. In this state, a process will not do
anything (not even terminate) until it receives a CONT signal.

system.processes_state

The number of new processes created.
system.forks

The total number of processes in the system.
system.active_processes

Context Switches, is the switching of the CPU from one process, task or thread
to another. If there are many processes or threads willing to execute and very
few CPU cores available to handle them, the system is making more context
switching to balance the CPU resources among them. The whole process is
computationally intensive. The more the context switches, the slower the system
gets.
system.ctxt



IDLEJITTER


Idle jitter is calculated by netdata. A thread is spawned that requests to sleep
for a few microseconds. When the system wakes it up, it measures how many
microseconds have passed. The difference between the requested and the actual
duration of the sleep, is the idle jitter. This number is useful in real-time
environments, where CPU jitter can affect the quality of the service (like VoIP
media gateways).
system.idlejitter



INTERRUPTS

Interrupts are signals sent to the CPU by external devices (normally I/O
devices) or programs (running processes). They tell the CPU to stop its current
activities and execute the appropriate part of the operating system. Interrupt
types are hardware (generated by hardware devices to signal that they need some
attention from the OS), software (generated by programs when they want to
request a system call to be performed by the operating system), and traps
(generated by the CPU itself to indicate that some error or condition occurred
for which assistance from the operating system is needed).

Total number of CPU interrupts. Check system.interrupts that gives more detail
about each interrupt and also the CPUs section where interrupts are analyzed per
CPU core.
system.intr

CPU interrupts in detail. At the CPUs section, interrupts are analyzed per CPU
core. The last column in /proc/interrupts provides an interrupt description or
the device name that registered the handler for that interrupt.
system.interrupts

system.irq_full_pressure

system.irq_full_pressure_stall_time



SOFTIRQS

Software interrupts (or "softirqs") are one of the oldest deferred-execution
mechanisms in the kernel. Several tasks among those executed by the kernel are
not critical: they can be deferred for a long period of time, if necessary. The
deferrable tasks can execute with all interrupts enabled (softirqs are patterned
after hardware interrupts). Taking them out of the interrupt handler helps keep
kernel response time small.


Total number of software interrupts in the system. At the CPUs section, softirqs
are analyzed per CPU core.

HI - high priority tasklets. TIMER - tasklets related to timer interrupts.
NET_TX, NET_RX - used for network transmit and receive processing. BLOCK -
handles block I/O completion events. IRQ_POLL - used by the IO subsystem to
increase performance (a NAPI like approach for block devices). TASKLET - handles
regular tasklets. SCHED - used by the scheduler to perform load-balancing and
other scheduling tasks. HRTIMER - used for high-resolution timers. RCU -
performs read-copy-update (RCU) processing.

system.softirqs



SOFTNET

Statistics for CPUs SoftIRQs related to network receive work. Break down per CPU
core can be found at CPU / softnet statistics. More information about
identifying and troubleshooting network driver related issues can be found at
Red Hat Enterprise Linux Network Performance Tuning Guide.

Processed - packets processed. Dropped - packets dropped because the network
device backlog was full. Squeezed - number of times the network device budget
was consumed or the time limit was reached, but more work was available.
ReceivedRPS - number of times this CPU has been woken up to process packets via
an Inter-processor Interrupt. FlowLimitCount - number of times the flow limit
has been reached (flow limiting is an optional Receive Packet Steering feature).


system.softnet_stat



ENTROPY


Entropy, is a pool of random numbers (/dev/random) that is mainly used in
cryptography. If the pool of entropy gets empty, processes requiring random
numbers may run a lot slower (it depends on the interface each program uses),
waiting for the pool to be replenished. Ideally a system with high entropy
demands should have a hardware device for that purpose (TPM is one such device).
There are also several software-only options you may install, like haveged,
although these are generally useful only in servers.
system.entropy



FILES


system.file_nr_used

system.file_nr_utilization



UPTIME


The amount of time the system has been running, including time spent in suspend.
system.uptime



CLOCK SYNCHRONIZATION

NTP lets you automatically sync your system time with a remote server. This
keeps your machine’s time accurate by syncing with servers that are known to
have accurate times.


The system clock synchronization state as provided by the ntp_adjtime() system
call. An unsynchronized clock may be the result of synchronization issues by the
NTP daemon or a hardware clock fault. It can take several minutes (usually up to
17) before NTP daemon selects a server to synchronize with.

State map: 0 - not synchronized, 1 - synchronized.

system.clock_sync_state


The kernel code can operate in various modes and with various features enabled
or disabled, as selected by the ntp_adjtime() system call. The system clock
status shows the value of the time_status variable in the kernel. The bits of
the variable are used to control these functions and record error conditions as
they exist.

UNSYNC - set/cleared by the caller to indicate clock unsynchronized (e.g., when
no peers are reachable). This flag is usually controlled by an application
program, but the operating system may also set it. CLOCKERR - set/cleared by the
external hardware clock driver to indicate hardware fault.

Status map: 0 - bit unset, 1 - bit set.

system.clock_status

A typical NTP client regularly polls one or more NTP servers. The client must
compute its time offset and round-trip delay. Time offset is the difference in
absolute time between the two clocks.
system.clock_sync_offset



IPC SEMAPHORES

System V semaphores is an inter-process communication (IPC) mechanism. It allows
processes or threads within a process to synchronize their actions. They are
often used to monitor and control the availability of system resources such as
shared memory segments. For details, see svipc(7). To see the host IPC semaphore
information, run ipcs -us. For limits, run ipcs -ls.

Number of allocated System V IPC semaphores. The system-wide limit on the number
of semaphores in all semaphore sets is specified in /proc/sys/kernel/sem file
(2nd field).
system.ipc_semaphores

Number of used System V IPC semaphore arrays (sets). Semaphores support
semaphore sets where each one is a counting semaphore. So when an application
requests semaphores, the kernel releases them in sets. The system-wide limit on
the maximum number of semaphore sets is specified in /proc/sys/kernel/sem file
(4th field).
system.ipc_semaphore_arrays



IPC SHARED MEMORY

System V shared memory is an inter-process communication (IPC) mechanism. It
allows processes to communicate information by sharing a region of memory. It is
the fastest form of inter-process communication available since no kernel
involvement occurs when data is passed between the processes (no copying).
Typically, processes must synchronize their access to a shared memory object,
using, for example, POSIX semaphores. For details, see svipc(7). To see the host
IPC shared memory information, run ipcs -um. For limits, run ipcs -lm.

Number of allocated System V IPC memory segments. The system-wide maximum number
of shared memory segments that can be created is specified in
/proc/sys/kernel/shmmni file.
system.shared_memory_segments

Amount of memory currently used by System V IPC memory segments. The run-time
limit on the maximum shared memory segment size that can be created is specified
in /proc/sys/kernel/shmmax file.

MEMORY

Detailed information about the memory management of the system.



OVERVIEW


Available Memory is estimated by the kernel, as the amount of RAM that can be
used by userspace processes, without causing swapping.
mem.available

Committed Memory, is the sum of all memory which has been allocated by
processes.
mem.committed

mem.directmaps



OOM KILLS


The number of processes killed by Out of Memory Killer. The kernel's OOM killer
is summoned when the system runs short of free memory and is unable to proceed
without killing one or more processes. It tries to pick the process whose demise
will free the most memory while causing the least misery for users of the
system. This counter also includes processes within containers that have
exceeded the memory limit.
mem.oom_kill



PAGE FAULTS



A page fault is a type of interrupt, called trap, raised by computer hardware
when a running program accesses a memory page that is mapped into the virtual
address space, but not actually loaded into main memory.



Minor - the page is loaded in memory at the time the fault is generated, but is
not marked in the memory management unit as being loaded in memory. Major -
generated when the system needs to load the memory page from disk or swap
memory.



mem.pgfaults



WRITEBACK


Dirty is the amount of memory waiting to be written to disk. Writeback is how
much memory is actively being written to disk.
mem.writeback



KERNEL



The total amount of memory being used by the kernel.

Slab - used by the kernel to cache data structures for its own use. KernelStack
- allocated for each task done by the kernel. PageTables - dedicated to the
lowest level of page tables (A page table is used to turn a virtual address into
a physical memory address). VmallocUsed - being used as virtual address space.
Percpu - allocated to the per-CPU allocator used to back per-CPU allocations
(excludes the cost of metadata). When you create a per-CPU variable, each
processor on the system gets its own copy of that variable.

mem.kernel



SLAB



Slab memory statistics.



Reclaimable - amount of memory which the kernel can reuse. Unreclaimable - can
not be reused even when the kernel is lacking memory.

mem.slab



RECLAIMING


mem.reclaiming



CMA


mem.cma



FRAGMENTATION

These charts show whether the kernel will compact memory or direct reclaim to
satisfy a high-order allocation. The extfrag/extfrag_index file in debugfs shows
what the fragmentation index for each order is in each zone in the system.Values
tending towards 0 imply allocations would fail due to lack of memory, values
towards 1000 imply failures are due to fragmentation and -1 implies that the
allocation will succeed as long as watermarks are met.

DISKS

Charts with performance information for all the system disks. Special care has
been given to present disk performance metrics in a way compatible with iostat
-x. netdata by default prevents rendering performance charts for individual
partitions and unmounted virtual disks. Disabled charts can still be enabled by
configuring the relative settings in the netdata configuration file.



SDA

disk.sda

disk.sda

disk_util.sda

The amount of data transferred to and from disk.
disk.sda

The amount of discarded data that are no longer in use by a mounted file system.
disk_ext.sda

Completed disk I/O operations. Keep in mind the number of operations requested
might be higher, since the system is able to merge adjacent to each other (see
merged operations chart).
disk_ops.sda


The number (after merges) of completed discard/flush requests.

Discard commands inform disks which blocks of data are no longer considered to
be in use and therefore can be erased internally. They are useful for
solid-state drivers (SSDs) and thinly-provisioned storage. Discarding/trimming
enables the SSD to handle garbage collection more efficiently, which would
otherwise slow future write operations to the involved blocks down.

Flush operations transfer all modified in-core data (i.e., modified buffer cache
pages) to the disk device so that all changed information can be retrieved even
if the system crashes or is rebooted. Flush requests are executed by disks.
Flush requests are not tracked for partitions. Before being merged, flush...

disk_ext_ops.sda

I/O operations currently in progress. This metric is a snapshot - it is not an
average over the last interval.
disk_qops.sda

Backlog is an indication of the duration of pending disk operations. On every
I/O event the system is multiplying the time spent doing I/O since the last
update of this field with the number of pending operations. While not accurate,
this metric can provide an indication of the expected completion time of the
operations in progress.
disk_backlog.sda

Disk Busy Time measures the amount of time the disk was busy with something.
disk_busy.sda

Disk Utilization measures the amount of time the disk was busy with something.
This is not related to its performance. 100% means that the system always had an
outstanding operation on the disk. Keep in mind that depending on the underlying
technology of the disk, 100% here may or may not be an indication of congestion.
disk_util.sda

The average time for I/O requests issued to the device to be served. This
includes the time spent by the requests in queue and the time spent servicing
them.
disk_await.sda

The average time for discard/flush requests issued to the device to be served.
This includes the time spent by the requests in queue and the time spent
servicing them.
disk_ext_await.sda

The average I/O operation size.
disk_avgsz.sda

The average discard operation size.
disk_ext_avgsz.sda

The average service time for completed I/O operations. This metric is calculated
using the total busy time of the disk and the number of completed operations. If
the disk is able to execute multiple parallel operations the reporting average
service time will be misleading.
disk_svctm.sda

The number of merged disk operations. The system is able to merge adjacent I/O
operations, for example two 4KB reads can become one 8KB read before given to
disk.
disk_mops.sda

The number of merged discard disk operations. Discard operations which are
adjacent to each other may be merged for efficiency.
disk_ext_mops.sda

The sum of the duration of all completed I/O operations. This number can exceed
the interval if the disk is able to execute I/O operations in parallel.
disk_iotime.sda

The sum of the duration of all completed discard/flush operations. This number
can exceed the interval if the disk is able to execute discard/flush operations
in parallel.

ip.tcpconnaborts


The accept queue of the kernel holds the fully established TCP connections,
waiting to be handled by the listening application.

Overflows - the number of established connections that could not be handled
because the receive queue of the listening application was full. Drops - number
of incoming connections that could not be handled, including SYN floods,
overflows, out of memory, security issues, no route to destination, reception of
related ICMP messages, socket is broadcast or multicast.



ip.tcp_accept_queue


TCP prevents out-of-order packets by either sequencing them in the correct order
or by requesting the retransmission of out-of-order packets.

Timestamp - detected re-ordering using the timestamp option. SACK - detected
re-ordering using Selective Acknowledgment algorithm. FACK - detected
re-ordering using Forward Acknowledgment algorithm. Reno - detected re-ordering
using Fast Retransmit algorithm.

ip.tcpreorders


TCP maintains an out-of-order queue to keep the out-of-order packets in the TCP
communication.

InQueue - the TCP layer receives an out-of-order packet and has enough memory to
queue it. Dropped - the TCP layer receives an out-of-order packet but does not
have enough memory, so drops it. Merged - the received out-of-order packet has
an overlay with the previous packet. The overlay part will be dropped. All these
packets will also be counted into InQueue. Pruned - packets dropped from
out-of-order queue because of socket buffer overrun.

IPV4 NETWORKING

Metrics for the IPv4 stack of the system. Internet Protocol version 4 (IPv4) is
the fourth version of the Internet Protocol (IP). It is one of the core
protocols of standards-based internetworking methods in the Internet. IPv4 is a
connectionless protocol for use on packet-switched networks. It operates on a
best effort delivery model, in that it does not guarantee delivery, nor does it
assure proper sequencing or avoidance of duplicate delivery. These aspects,
including data integrity, are addressed by an upper layer transport protocol,
such as the Transmission Control Protocol (TCP).



PACKETS



IPv4 packets statistics for this host.

Received - packets received by the IP layer. This counter will be increased even
if the packet is dropped later. Sent - packets sent via IP layer, for both
single cast and multicast packets. This counter does not include any packets
counted in Forwarded. Forwarded - input packets for which this host was not
their final IP destination, as a result of which an attempt was made to find a
route to forward them to that final destination. In hosts which do not act as IP
Gateways, this counter will include only those packets which were Source-Routed
and the Source-Route option processing was successful. Delivered - packets
delivered to the upper layer protocols, e.g. TCP, UDP, ICMP, and so on.

ipv4.packets



ERRORS

InDiscards, OutDiscards - inbound and outbound packets which were chosen to be
discarded even though no errors had been detected to prevent their being
deliverable to a higher-layer protocol. InHdrErrors - input packets that have
been discarded due to errors in their IP headers, including bad checksums,
version number mismatch, other format errors, time-to-live exceeded, errors
discovered in processing their IP options, etc. OutNoRoutes - packets that have

NETWORK INTERFACES

Performance metrics for network interfaces.

Netdata retrieves this data reading the /proc/net/dev file and /sys/class/net/
directory.




WLP1S0

net.wlp1s0

net.wlp1s0

The amount of traffic transferred by the network interface.
net.wlp1s0

The number of packets transferred by the network interface. Received multicast
counter is commonly calculated at the device level (unlike received) and
therefore may include packets which did not reach the host.
net_packets.wlp1s0

The interface's latest or current speed that the network adapter negotiated with
the device it is connected to. This does not give the max supported speed of the
NIC.
net_speed.wlp1s0


The interface's latest or current duplex that the network adapter negotiated
with the device it is connected to.

Unknown - the duplex mode can not be determined. Half duplex - the communication
is one direction at a time. Full duplex - the interface is able to send and
receive data simultaneously.

net_duplex.wlp1s0


The current operational state of the interface.

Unknown - the state can not be determined. NotPresent - the interface has
missing (typically, hardware) components. Down - the interface is unable to
transfer data on L1, e.g. ethernet is not plugged or interface is
administratively down. LowerLayerDown - the interface is down due to state of
lower-layer interface(s). Testing - the interface is in testing mode, e.g. cable
test. It can’t be used for normal traffic until tests complete. Dormant - the
interface is L1 up, but waiting for an external event, e.g. for a protocol to
establish. Up - the interface is ready to pass packets and can be used.

net_operstate.wlp1s0

The current physical link state of the interface.
net_carrier.wlp1s0

The interface's currently configured Maximum transmission unit (MTU) value. MTU
is the size of the largest protocol data unit that can be communicated in a
single network layer transaction.
net_mtu.wlp1s0



ENP2S0



The interface's latest or current duplex that the network adapter negotiated
with the device it is connected to.

Unknown - the duplex mode can not be determined. Half duplex - the communication
is one direction at a time. Full duplex - the interface is able to send and
receive data simultaneously.

net_duplex.enp2s0


The current operational state of the interface.

Unknown - the state can not be determined. NotPresent - the interface has
missing (typically, hardware) components. Down - the interface is unable to
transfer data on L1, e.g. ethernet is not plugged or interface is
administratively down. LowerLayerDown - the interface is down due to state of
lower-layer interface(s). Testing - the interface is in testing mode, e.g. cable
test. It can’t be used for normal traffic until tests complete. Dormant - the
interface is L1 up, but waiting for an external event, e.g. for a protocol to
establish. Up - the interface is ready to pass packets and can be used.

net_operstate.enp2s0

The current physical link state of the interface.
net_carrier.enp2s0

The interface's currently configured Maximum transmission unit (MTU) value. MTU
is the size of the largest protocol data unit that can be communicated in a
single network layer transaction.
net_mtu.enp2s0



DOCKER0



The current operational state of the interface.

Unknown - the state can not be determined. NotPresent - the interface has
missing (typically, hardware) components. Down - the interface is unable to
transfer data on L1, e.g. ethernet is not plugged or interface is
administratively down. LowerLayerDown - the interface is down due to state of
lower-layer interface(s). Testing - the interface is in testing mode, e.g. cable
test. It can’t be used for normal traffic until tests complete. Dormant - the
interface is L1 up, but waiting for an external event, e.g. for a protocol to
establish. Up - the interface is ready to pass packets and can be used.

net_operstate.docker0

The current physical link state of the interface.
net_carrier.docker0

The interface's currently configured Maximum transmission unit (MTU) value. MTU
is the size of the largest protocol data unit that can be communicated in a
single network layer transaction.
net_mtu.docker0


--------------------------------------------------------------------------------


WIRELESS INTERFACES

Performance metrics for wireless interfaces.



WLP1S0


wireless.wlp1s0_status

Overall quality of the link. May be based on the level of contention or
interference, the bit or frame error rate, how good the received signal is, some
timing synchronisation, or other hardware metric.
wireless.wlp1s0_link_quality

Received signal strength (RSSI).
wireless.wlp1s0_signal_level

Background noise level (when no packet is transmitted).
wireless.wlp1s0_noise_level


The number of discarded packets.



NWID - received packets with a different NWID or ESSID. Used to detect
configuration problems or adjacent network existence (on the same frequency).
Crypt - received packets that the hardware was unable to code/encode. This can
be used to detect invalid encryption settings. Frag - received packets for which
the hardware was not able to properly re-assemble the link layer fragments (most
likely one was missing). Retry - packets that the hardware failed to deliver.
Most MAC protocols will retry the packet a number of times before giving up.
Misc - other packets lost in relation with specific wireless operations.



wireless.wlp1s0_discarded_packets

The number of periodic beacons from the Cell or the Access Point have been
missed. Beacons are sent at regular intervals to maintain the cell coordination,
failure to receive them usually indicates that the card is out of range.
wireless.wlp1s0_missed_beacon


--------------------------------------------------------------------------------


FIREWALL (NETFILTER)

Performance metrics of the netfilter components.



CONNECTION TRACKER

Netfilter Connection Tracker performance metrics. The connection tracker keeps
track of all connections of the machine, inbound and outbound. It works by
keeping a database with all open connections, tracking network and address
translation and connection expectations.

The number of entries in the conntrack table.
netfilter.conntrack_sockets


Packet tracking statistics. New (since v4.9) and Ignore (since v5.10) are
hardcoded to zeros in the latest kernel.

New - conntrack entries added which were not expected before. Ignore - packets
seen which are already connected to a conntrack entry. Invalid - packets seen
which can not be tracked.

netfilter.conntrack_new


The number of changes in conntrack tables.

Inserted, Deleted - conntrack entries which were inserted or removed.
Delete-list - conntrack entries which were put to dying list.

netfilter.conntrack_changes


The number of events in the "expect" table. Connection tracking expectations are
the mechanism used to "expect" RELATED connections to existing ones. An
expectation is a connection that is expected to happen in a period of time.

Created, Deleted - conntrack entries which were inserted or removed. New -
conntrack entries added after an expectation for them was already present.

netfilter.conntrack_expect


Conntrack errors.

IcmpError - packets which could not be tracked due to error situation.
InsertFailed - entries for which list insertion was attempted but failed
(happens if the same entry is already present). Drop - packets dropped due to
conntrack failure. Either new conntrack entry allocation failed, or protocol
helper dropped the packet. EarlyDrop - dropped conntrack entries to make room
for new ones, if maximum table size was reached.

netfilter.conntrack_errors


Conntrack table lookup statistics.

Searched - conntrack table lookups performed. Restarted - conntrack table
lookups which had to be restarted due to hashtable resizes. Found - conntrack
table lookups which were successful.

netfilter.conntrack_search

LOGIND

Keeps track of user logins and sessions by querying the systemd-logind API.



SESSIONS


Local and remote sessions.
logind.sessions


Sessions of each session type.

Graphical - sessions are running under one of X11, Mir, or Wayland. Console -
sessions are usually regular text mode local logins, but depending on how the
system is configured may have an associated GUI. Other - sessions are those that
do not fall into the above categories (such as sessions for cron jobs or systemd
timer units).

logind.sessions_type


Sessions in each session state.

Online - logged in and running in the background. Closing - nominally logged
out, but some processes belonging to it are still around. Active - logged in and
running in the foreground.

logind.sessions_state



USERS



Users in each user state.

Offline - users are not logged in. Closing - users are in the process of logging
out without lingering. Online - users are logged in, but have no active
sessions. Lingering - users are not logged in, but have one or more services
still running. Active - users are logged in, and have at least one active
session.

POSTGRESQL LOCAL

Performance metrics for PostgreSQL, the open source object-relational database
management system (ORDBMS).



CONNECTIONS

A connection is an established line of communication between a client and the
PostgreSQL server. Each connection adds to the load on the PostgreSQL server. To
guard against running out of memory or overloading the database the
max_connections parameter (default = 100) defines the maximum number of
concurrent connections to the database server. A separate parameter,
superuser_reserved_connections (default = 3), defines the quota for superuser
connections (so that superusers can connect even if all other connection slots
are blocked).

Total connection utilization across all databases. Utilization is measured as a
percentage of (max_connections - superuser_reserved_connections). If the
utilization is 100% no more new connections will be accepted (superuser
connections will still be accepted if superuser quota is available).
postgres_local.connections_utilization


Connections usage across all databases. The maximum number of concurrent
connections to the database server is (max_connections -
superuser_reserved_connections). As a general rule, if you need more than 200
connections it is advisable to use connection pooling.

Available - new connections allowed. Used - connections currently in use.

postgres_local.connections_usage


Number of connections in each state across all databases.

Active - the backend is executing query. Idle - the backend is waiting for a new
client command. IdleInTransaction - the backend is in a transaction, but is not
currently executing a query. IdleInTransactionAborted - the backend is in a
transaction, and not currently executing a query, but one of the statements in
the transaction caused an error. FastPathFunctionCall - the backend is executing
a fast-path function. Disabled - is reported if track_activities is disabled in
this backend.

postgres_local.connections_state

Connection utilization per database. Utilization is measured as a percentage of
CONNECTION LIMIT per database (if set) or max_connections (if CONNECTION LIMIT
is not set).
postgres_local.db_mealie_connections_utilization

Connection utilization per database. Utilization is measured as a percentage of
CONNECTION LIMIT per database (if set) or max_connections (if CONNECTION LIMIT
is not set).
postgres_local.db_postgres_connections_utilization

Number of current connections per database.
postgres_local.db_mealie_connections

Number of current connections per database.
postgres_local.db_postgres_connections



TRANSACTIONS


Running transactions duration histogram. The bins are specified as consecutive,
non-overlapping intervals. The value is the number of observed transactions that
fall into each interval.
postgres_local.transactions_duration

Percentage of committed/rollback transactions.
postgres_local.db_mealie_transactions_ratio

Percentage of committed/rollback transactions.
postgres_local.db_postgres_transactions_ratio


Number of transactions that have been performed

Committed - transactions that have been committed. All changes made by the
committed transaction become visible to others and are guaranteed to be durable
if a crash occurs. Rollback - transactions that have been rolled back. Rollback
aborts the current transaction and causes all the updates made by the
transaction to be discarded. Single queries that have failed outside the
transactions are also accounted as rollbacks.

postgres_local.db_mealie_transactions_rate


Number of transactions that have been performed

Committed - transactions that have been committed. All changes made by the
committed transaction become visible to others and are guaranteed to be durable
if a crash occurs. Rollback - transactions that have been rolled back. Rollback
aborts the current transaction and causes all the updates made by the
transaction to be discarded. Single queries that have failed outside the
transactions are also accounted as rollbacks.

postgres_local.db_postgres_transactions_rate



QUERIES


Active queries duration histogram. The bins are specified as consecutive,
non-overlapping intervals. The value is the number of observed active queries
that fall into each interval.
postgres_local.queries_duration



THROUGHPUT


The percentage of rows that contain data needed to execute the query, out of the
total number of rows scanned. A high value indicates that the database is
executing queries efficiently, while a low value indicates that the database is
performing extra work by scanning a large number of rows that aren't required to
process the query. Low values may be caused by missing indexes or inefficient
queries.
postgres_local.db_mealie_db_ops_fetched_rows_ratio

The percentage of rows that contain data needed to execute the query, out of the
total number of rows scanned. A high value indicates that the database is
executing queries efficiently, while a low value indicates that the database is
performing extra work by scanning a large number of rows that aren't required to
process the query. Low values may be caused by missing indexes or inefficient
queries.
postgres_local.db_postgres_db_ops_fetched_rows_ratio


Read queries throughput.

Returned - Total number of rows scanned by queries. This value indicates rows
returned by the storage layer to be scanned, not rows returned to the client.
Fetched - Subset of scanned rows (Returned) that contained data needed to
execute the query.

postgres_local.db_mealie_ops_read_rows_rate


Read queries throughput.

Returned - Total number of rows scanned by queries. This value indicates rows
returned by the storage layer to be scanned, not rows returned to the client.
Fetched - Subset of scanned rows (Returned) that contained data needed to
execute the query.

postgres_local.db_postgres_ops_read_rows_rate


Write queries throughput.

Inserted - number of rows inserted by queries. Deleted - number of rows deleted
by queries. Updated - number of rows updated by queries.

postgres_local.db_mealie_ops_write_rows_rate

by queries. Updated - number of rows updated by queries.

postgres_local.db_postgres_ops_write_rows_rate

Number of temporary files created by queries. Complex queries may require more
memory than is available (specified by work_mem). When this happens, Postgres
reverts to using temporary files - they are actually stored on disk, but only
exist for the duration of the request. After the request returns, the temporary
files are deleted.
postgres_local.db_mealie_temp_files_files_created_rate

Number of temporary files created by queries. Complex queries may require more
memory than is available (specified by work_mem). When this happens, Postgres
reverts to using temporary files - they are actually stored on disk, but only
exist for the duration of the request. After the request returns, the temporary
files are deleted.
postgres_local.db_postgres_temp_files_files_created_rate

Amount of data written temporarily to disk to execute queries.
postgres_local.db_mealie_temp_files_io_rate

Amount of data written temporarily to disk to execute queries.
postgres_local.db_postgres_temp_files_io_rate



CACHE


PostgreSQL uses a shared buffer cache to store frequently accessed data in
memory, and avoid slower disk reads. If you are seeing performance issues,
consider increasing the shared_buffers size or tuning effective_cache_size.
postgres_local.db_mealie_cache_io_ratio

PostgreSQL uses a shared buffer cache to store frequently accessed data in
memory, and avoid slower disk reads. If you are seeing performance issues,
consider increasing the shared_buffers size or tuning effective_cache_size.
postgres_local.db_postgres_cache_io_ratio


Amount of data read from shared buffer cache or from disk.

Disk - data read from disk. Memory - data read from buffer cache (this only
includes hits in the PostgreSQL buffer cache, not the operating system's file
system cache).

postgres_local.db_mealie_io_rate


Amount of data read from shared buffer cache or from disk.

Disk - data read from disk. Memory - data read from buffer cache (this only
includes hits in the PostgreSQL buffer cache, not the operating system's file
system cache).

postgres_local.db_postgres_io_rate



SIZE


Actual on-disk usage of the database's data directory and any associated
tablespaces.
postgres_local.db_mealie_size

Actual on-disk usage of the database's data directory and any associated
tablespaces.
postgres_local.db_postgres_size



LOCKS


postgres_local.locks_utilization

Number of held locks. Some of these lock modes are acquired by PostgreSQL
automatically before statement execution, while others are provided to be used
by applications. All lock modes acquired in a transaction are held for the
duration of the transaction. For lock modes details, see table-level locks.
postgres_local.db_mealie_locks_held

Number of held locks. Some of these lock modes are acquired by PostgreSQL
automatically before statement execution, while others are provided to be used
by applications. All lock modes acquired in a transaction are held for the
duration of the transaction. For lock modes details, see table-level locks.
postgres_local.db_postgres_locks_held

Number of awaited locks. It indicates that some transaction is currently waiting
to acquire a lock, which implies that some other transaction is holding a
conflicting lock mode on the same lockable object. For lock modes details, see
table-level locks.
postgres_local.db_mealie_locks_awaited_count

Number of awaited locks. It indicates that some transaction is currently waiting
to acquire a lock, which implies that some other transaction is holding a
conflicting lock mode on the same lockable object. For lock modes details, see
table-level locks.
postgres_local.db_postgres_locks_awaited_count

Number of detected deadlocks. When a transaction cannot acquire the requested
lock within a certain amount of time (configured by deadlock_timeout), it begins
deadlock detection.
postgres_local.db_mealie_deadlocks_rate

Number of detected deadlocks. When a transaction cannot acquire the requested
lock within a certain amount of time (configured by deadlock_timeout), it begins
deadlock detection.
postgres_local.db_postgres_deadlocks_rate



VACUUM AND ANALYZE


PostgreSQL databases require periodic maintenance known as vacuuming. For many
installations, it is sufficient to let vacuuming be performed by the autovacuum
daemon. For more information see The Autovacuum Daemon.
postgres_local.autovacuum_workers_count



MAINTENANCE



Number of checkpoints that have been performed. Checkpoints are periodic
maintenance operations the database performs to make sure that everything it's
been caching in memory has been synchronized with the disk. Ideally checkpoints
should be time-driven (scheduled) as opposed to load-driven (requested).

Scheduled - checkpoints triggered as per schedule when time elapsed from the
previous checkpoint is greater than checkpoint_timeout. Requested - checkpoints
triggered due to WAL updates reaching the max_wal_size before the
checkpoint_timeout is reached.

postgres_local.checkpoints_rate


Checkpoint timing information. An important indicator of how well checkpoint I/O
is performing is the amount of time taken to sync files to disk.

Write - amount of time spent writing files to disk during checkpoint processing.
Sync - amount of time spent synchronizing files to disk during checkpoint
processing.

postgres_local.checkpoints_time

Number of times the background writer stopped a cleaning scan because it had
written too many buffers (exceeding the value of bgwriter_lru_maxpages).
postgres_local.bgwriter_halts_rate


Amount of data flushed from memory to disk.

Checkpoint - buffers written during checkpoints. Backend - buffers written
directly by a backend. It may happen that a dirty page is requested by a backend
process. In this case the page is synced to disk before the page is returned to
the client. BgWriter - buffers written by the background writer. PostgreSQL may
clear pages with a low usage count in advance. The process scans for dirty pages
with a low usage count so that they could be cleared if necessary. Buffers
written by this process increment the counter.

postgres_local.buffers_io_rate

Number of times a backend had to execute its own fsync call (normally the
background writer handles those even when the backend does its own write). Any
values above zero can indicate problems with storage when fsync queue is
completely filled.
postgres_local.buffers_backend_fsync_rate

Allocated and re-allocated buffers. If a backend process requests data it is
either found in a block in shared buffer cache or the block has to be allocated
(read from disk). The latter is counted as Allocated.
postgres_local.buffers_alloc_rate

Percentage towards emergency autovacuum for one or more tables. A forced
autovacuum will run once this value reaches 100%. For more information see
Preventing Transaction ID Wraparound Failures.
postgres_local.txid_exhaustion_towards_autovacuum_perc

Percentage towards transaction wraparound. A transaction wraparound may occur
when this value reaches 100%. For more information see Preventing Transaction ID
Wraparound Failures.
postgres_local.txid_exhaustion_perc

The oldest current transaction ID (XID). If for some reason autovacuum fails to
clear old XIDs from a table, the system will begin to emit warning messages when
the database's oldest XIDs reach eleven million transactions from the wraparound
point. For more information see Preventing Transaction ID Wraparound Failures.
postgres_local.txid_exhaustion_oldest_txid_num



WAL


Write-Ahead Logging (WAL) ensures data integrity by ensuring that changes to
data files (where tables and indexes reside) are written only after log records
describing the changes have been flushed to permanent storage.
postgres_local.wal_io_rate


Number of WAL logs stored in the directory pg_wal under the data directory.

Written - generated log segments files. Recycled - old log segment files that
are no longer needed. Renamed to become future segments in the numbered sequence
to avoid the need to create new ones.

postgres_local.wal_files_count


WAL archiving.

Ready - WAL files waiting to be archived. A non-zero value can indicate
archive_command is in error, see Continuous Archiving and Point-in-Time
Recovery. Done - WAL files successfully archived.

postgres_local.wal_archiving_files_count



CATALOG


postgres_local.databases_count

postgres_local.catalog_relations_count

postgres_local.catalog_relations_size



UPTIME


The time elapsed since the Postgres process was started.

SYSTEMD UNITS SERVICE-UNITS

systemd provides a dependency system between various entities called "units" of
11 different types. Units encapsulate various objects that are relevant for
system boot-up and maintenance. Units may be active (meaning started, bound,
plugged in, depending on the unit type), or inactive (meaning stopped, unbound,
unplugged), as well as in the process of being activated or deactivated, i.e.
between the two states (these states are called activating, deactivating). A
special failed state is available as well, which is very similar to inactive and
is entered when the service failed in some way (process returned error code on
exit, or crashed, an operation timed out, or after too many restarts). For
details, see systemd(1).

XSS PROTECTION

This dashboard is about to render data from server:



To protect your privacy, the dashboard will check all data transferred for cross
site scripting (XSS).
This is CPU intensive, so your browser might be a bit slower.

If you trust the remote server, you can disable XSS protection.
In this case, any remote dashboard decoration code (javascript) will also run.

If you don't trust the remote server, you should keep the protection on.
The dashboard will run slower and remote dashboard decoration code will not run,
but better be safe than sorry...

Keep protecting me I don't need this, the server is mine

PRINT THIS NETDATA DASHBOARD

netdata dashboards cannot be captured, since we are lazy loading and hiding all
but the visible charts.
To capture the whole page with all the charts rendered, a new browser window
will pop-up that will render all the charts at once. The new browser window will
maintain the current pan and zoom settings of the charts. So, align the charts
before proceeding.

This process will put some CPU and memory pressure on your browser.
For the netdata server, we will sequentially download all the charts, to avoid
congesting network and server resources.
Please, do not print netdata dashboards on paper!

IMPORT A NETDATA SNAPSHOT

netdata can export and import dashboard snapshots. Any netdata can import the
snapshot of any other netdata. The snapshots are not uploaded to a server. They
are handled entirely by your web browser, on your computer.

Click here to select the netdata snapshot file to import

Browse for a snapshot file (or drag it and drop it here), then click Import to
render it.

Comments
 
Select snaphost resolution. This controls the size the snapshot file.

The generated snapshot will include all charts of this dashboard, for the
visible timeframe, so align, pan and zoom the charts as needed. The scroll
position of the dashboard will also be saved. The snapshot will be downloaded as
a file, to your computer, that can be imported back into any netdata dashboard
(no need to import it back on this server).

Snapshot files include all the information of the dashboard, including the URL
of the origin server, its netdata unique ID, etc. So, if you share the snapshot
file with third parties, they will be able to access the origin server, if this
server is exposed on the internet.
Snapshots are handled entirely by the web browser. The netdata servers are not
aware of them.

NETDATA DASHBOARD OPTIONS

These are browser settings. Each viewer has its own. They do not affect the
operation of your netdata server.
Settings take effect immediately and are saved permanently to browser local
storage (except the refresh on focus / always option).
To reset all options (including charts sizes) to their defaults, click here.

 * Performance
 * Synchronization
 * Visual
 * Locale

On FocusAlways
When to refresh the charts?
When set to On Focus, the charts will stop being updated if the page / tab does
not have the focus of the user. When set to Always, the charts will always be
refreshed. Set it to On Focus it to lower the CPU requirements of the browser
(and extend the battery of laptops and tablets) when this page does not have
your focus. Set to Always to work on another window (i.e. change the settings of
something) and have the charts auto-refresh in this window.
Non ZeroAll
Which dimensions to show?
When set to Non Zero, dimensions that have all their values (within the current
view) set to zero will not be transferred from the netdata server (except if all
dimensions of the chart are zero, in which case this setting does nothing - all
dimensions are transferred and shown). When set to All, all dimensions will
always be shown. Set it to Non Zero to lower the data transferred between
netdata and your browser, lower the CPU requirements of your browser (fewer
lines to draw) and increase the focus on the legends (fewer entries at the
legends).
DestroyHide
How to handle hidden charts?
When set to Destroy, charts that are not in the current viewport of the browser
(are above, or below the visible area of the page), will be destroyed and
re-created if and when they become visible again. When set to Hide, the
not-visible charts will be just hidden, to simplify the DOM and speed up your
browser. Set it to Destroy, to lower the memory requirements of your browser.
Set it to Hide for faster restoration of charts on page scrolling.
AsyncSync
Page scroll handling?
When set to Sync, charts will be examined for their visibility immediately after
scrolling. On slow computers this may impact the smoothness of page scrolling.
To update the page when scrolling ends, set it to Async. Set it to Sync for
immediate chart updates when scrolling. Set it to Async for smoother page
scrolling on slower computers.

ParallelSequential
Which chart refresh policy to use?
When set to parallel, visible charts are refreshed in parallel (all queries are
sent to netdata server in parallel) and are rendered asynchronously. When set to
sequential charts are refreshed one after another. Set it to parallel if your
browser can cope with it (most modern browsers do), set it to sequential if you
work on an older/slower computer.
ResyncBest Effort
Shall we re-sync chart refreshes?
When set to Resync, the dashboard will attempt to re-synchronize all the charts
so that they are refreshed concurrently. When set to Best Effort, each chart may
be refreshed with a little time difference to the others. Normally, the
dashboard starts refreshing them in parallel, but depending on the speed of your
computer and the network latencies, charts start having a slight time
difference. Setting this to Resync will attempt to re-synchronize the charts on
every update. Setting it to Best Effort may lower the pressure on your browser
and the network.
SyncDon't Sync
Sync hover selection on all charts?
When enabled, a selection on one chart will automatically select the same time
on all other visible charts and the legends of all visible charts will be
updated to show the selected values. When disabled, only the chart getting the
user's attention will be selected. Enable it to get better insights of the data.
Disable it if you are on a very slow computer that cannot actually do it.

RightBelow
Where do you want to see the legend?
Netdata can place the legend in two positions: Below charts (the default) or to
the Right of charts.
Switching this will reload the dashboard.
DarkWhite
Which theme to use?
Netdata comes with two themes: Dark (the default) and White.
Switching this will reload the dashboard.
Help MeNo Help
Do you need help?
Netdata can show some help in some areas to help you use the dashboard. If all
these balloons bother you, disable them using this switch.
Switching this will reload the dashboard.
PadDon't Pad
Enable data padding when panning and zooming?
When set to Pad the charts will be padded with more data, both before and after
the visible area, thus giving the impression the whole database is loaded. This
padding will happen only after the first pan or zoom operation on the chart
(initially all charts have only the visible data). When set to Don't Pad only
the visible data will be transferred from the netdata server, even after the
first pan and zoom operation.
SmoothRough
Enable Bézier lines on charts?
When set to Smooth the charts libraries that support it, will plot smooth curves
instead of simple straight lines to connect the points.
Keep in mind dygraphs, the main charting library in netdata dashboards, can only
smooth line charts. It cannot smooth area or stacked charts. When set to Rough,
this setting can lower the CPU resources consumed by your browser.

These settings are applied gradually, as charts are updated. To force them,
refresh the dashboard now.
Scale UnitsFixed Units
Enable auto-scaling of select units?
When set to Scale Units the values shown will dynamically be scaled (e.g. 1000
kilobits will be shown as 1 megabit). Netdata can auto-scale these original
units: kilobits/s, kilobytes/s, KB/s, KB, MB, and GB. When set to Fixed Units
all the values will be rendered using the original units maintained by the
netdata server.
CelsiusFahrenheit
Which units to use for temperatures?
Set the temperature units of the dashboard.
TimeSeconds
Convert seconds to time?
When set to Time, charts that present seconds will show DDd:HH:MM:SS. When set
to Seconds, the raw number of seconds will be presented.
