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
(0.17%). If it is constantly high, your disks are a bottleneck and they slow
your system down.
An important metric worth monitoring, is softirq

softirq
(0.34%). A constantly high percentage of softirq may indicate network driver
issues. The individual metrics can be found in the kernel documentation.

Pressure Stall Information identifies and quantifies the disruptions caused by
resource contentions. The "some" line indicates the share of time in which at
least some tasks are stalled on CPU. The ratios (in %) are tracked as recent
trends over 10-, 60-, and 300-second windows.

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.

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

Pressure Stall Information identifies and quantifies the disruptions caused by
resource contentions. The "some" line indicates the share of time in which at
least some tasks are stalled on I/O. The "full" line indicates the share of time
in which all non-idle tasks are stalled on I/O 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. The ratios (in %) are tracked as
recent trends over 10-, 60-, and 300-second windows.
system.io_some_pressure

system.io_full_pressure



RAM


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

Pressure Stall Information identifies and quantifies the disruptions caused by
resource contentions. The "some" line indicates the share of time in which at
least some tasks are stalled on memory. The "full" line indicates the share of
time in which all non-idle tasks are stalled on memory 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. The ratios (in %) are tracked
as recent trends over 10-, 60-, and 300-second windows.
system.memory_some_pressure

system.memory_full_pressure



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.

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

Number of times that either do_fork, or kernel_clone if you are running kernel
newer than 5.9.16, is called to create a new task, which is the common name used
to define process and tasks inside the kernel. Netdata identifies the threads
monitoring tracepoint sched_process_fork. This chart is provided by eBPF plugin.
system.process_thread

Calls for the functions responsible for closing (do_exit) and releasing
(release_task) tasks. This chart is provided by eBPF plugin.
system.exit

Difference between the number of process created and the number of threads
created per period(process dimension), it also shows the number of possible
zombie process running on system. This chart is provided by eBPF plugin.
system.process_status



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

Total time spent servicing hardware interrupts. Based on the eBPF hardirqs from
BCC tools.
system.hardirq_latency



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



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. It is strongly recommended having the
clock in sync with reliable NTP servers. Otherwise, it leads to unpredictable
problems. 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

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.
system.shared_memory_bytes

Monitor calls to functions shmget, shmat, shmdt, and shmctl. When integration
with apps is enabled, Netdata also shows shared memory system call usage per
application.
system.shared_memory_calls

MEMORY

Detailed information about the memory management of the system.



SYSTEM


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

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

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


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



KERNEL


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


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



HUGEPAGES

Hugepages is a feature that allows the kernel to utilize the multiple page size
capabilities of modern hardware architectures. The kernel creates multiple pages
of virtual memory, mapped from both physical RAM and swap. There is a mechanism
in the CPU architecture called "Translation Lookaside Buffers" (TLB) to manage
the mapping of virtual memory pages to actual physical memory addresses. The TLB
is a limited hardware resource, so utilizing a large amount of physical memory
with the default page size consumes the TLB and adds processing overhead. By
utilizing Huge Pages, the kernel is able to create pages of much larger sizes,
each page consuming a single resource in the TLB. Huge Pages are pinned to
physical RAM and cannot be swapped/paged out.

Transparent HugePages (THP) is backing virtual memory with huge pages,
supporting automatic promotion and demotion of page sizes. It works for all
applications for anonymous memory mappings and tmpfs/shmem.
mem.transparent_hugepages



SYNCHRONIZATION (EBPF)


System calls for fsync() and fdatasync() transfer all modified page caches for
the files on disk devices. These calls block until the device reports that the
transfer has been completed.
mem.file_sync

System calls for msync() which flushes changes made to the in-core copy of a
file that was mapped.
mem.memory_map

System calls for sync() and syncfs() which flush the file system buffers to
storage devices. Performance perturbations might be caused by these calls. The
sync() calls are based on the eBPF syncsnoop from BCC tools.
mem.sync

System calls for sync_file_range() permits fine control when synchronizing the
open file referred to by the file descriptor fd with disk. This system call is
extremely dangerous and should not be used in portable programs.
mem.file_segment


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


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.



VDA

disk.vda

disk.vda

disk_util.vda

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

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

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.vda


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.vda

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

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.vda

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

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.vda

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.vda

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.vda

The average I/O operation size.
disk_avgsz.vda

The average discard operation size.
disk_ext_avgsz.vda

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.vda

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.vda

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

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.vda

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.

NETWORKING STACK

Metrics for the networking stack of the system. These metrics are collected from
/proc/net/netstat or attaching kprobes to kernel functions, apply to both IPv4
and IPv6 traffic and are related to operation of the kernel networking stack.



TCP



TCP connection aborts.

BadData - happens while the connection is on FIN_WAIT1 and the kernel receives a
packet with a sequence number beyond the last one for this connection - the
kernel responds with RST (closes the connection). UserClosed - happens when the
kernel receives data on an already closed connection and responds with RST.
NoMemory - happens when there are too many orphaned sockets (not attached to an
fd) and the kernel has to drop a connection - sometimes it will send an RST,

ip.tcpconnaborts


The SYN queue of the kernel tracks TCP handshakes until connections get fully
established. It overflows when too many incoming TCP connection requests hang in
the half-open state and the server is not configured to fall back to SYN
cookies. Overflows are usually caused by SYN flood DoS attacks.

Drops - number of connections dropped because the SYN queue was full and SYN
cookies were disabled. Cookies - number of SYN cookies sent because the SYN
queue was full.

ip.tcp_syn_queue


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.

ip.tcpofo


SYN cookies are used to mitigate SYN flood.

Received - after sending a SYN cookie, it came back to us and passed the check.
Sent - an application was not able to accept a connection fast enough, so the
kernel could not store an entry in the queue for this connection. Instead of
dropping it, it sent a SYN cookie to the client. Failed - the MSS decoded from
the SYN cookie is invalid. When this counter is incremented, the received packet
won’t be treated as a SYN cookie.

ip.tcpsyncookies



ECN

Explicit Congestion Notification (ECN) is an extension to the IP and to the TCP
that allows end-to-end notification of network congestion without dropping
packets. ECN is an optional feature that may be used between two ECN-enabled
endpoints when the underlying network infrastructure also supports it.


Total number of received IP packets with ECN bits set in the system.

CEP - congestion encountered. NoECTP - non ECN-capable transport. ECTP0 and
ECTP1 - ECN capable transport.

ip.ecnpkts


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


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).



SOCKETS


The total number of used sockets for all address families in this system.
ipv4.sockstat_sockets



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



The number of discarded IPv4 packets.

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
been discarded because no route could be found to transmit them to their
destination. This includes any packets which a host cannot route because all of
its default gateways are down. InAddrErrors - input packets that have been
discarded du...

ICMP



The number of transferred IPv4 ICMP messages.

Received, Sent - ICMP messages which the host received and attempted to send.
Both these counters include errors.

ipv4.icmp


The number of IPv4 ICMP errors.

InErrors - received ICMP messages but determined as having ICMP-specific errors,

IPV6 NETWORKING

Metrics for the IPv6 stack of the system. Internet Protocol version 6 (IPv6) is
the most recent version of the Internet Protocol (IP), the communications
protocol that provides an identification and location system for computers on
networks and routes traffic across the Internet. IPv6 was developed by the
Internet Engineering Task Force (IETF) to deal with the long-anticipated problem
of IPv4 address exhaustion. IPv6 is intended to replace IPv4.



PACKETS



IPv6 packet 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. Delivers - packets
delivered to the upper layer protocols, e.g. TCP, UDP, ICMP, and so on.

no errors had been detected to prevent their being deliverable to a higher-layer
protocol. InHdrErrors - errors in IP headers, including bad checksums, version
number mismatch, other format errors, time-to-live exceeded, etc. InAddrErrors -
invalid IP address or the destination IP address is not a local address and IP
forwarding is not enabled. InUnknownProtos - unknown or unsupported protocol.
InTooBigErrors - the size exceeded the link MTU. InTruncatedPkts - packet frame
did not carry enough data. InNoRoutes - no route could be found while
forwarding. OutNoRoutes - no route could be found for packets generated by this
host.

WEB LOG APACHE VHOSTS

Information extracted from a server log file. web_log plugin incrementally
parses the server log file to provide, in real-time, a break down of key server
performance metrics. For web servers, an extended log file format may optionally
be used (for nginx and apache) offering timing information and bandwidth for
both requests and responses. web_log plugin may also be configured to provide a
break down of requests per URL pattern (check
/etc/netdata/python.d/web_log.conf).
web_log_apache_vhosts.response_statuses

web_log_apache_vhosts.response_statuses

web_log_apache_vhosts.response_statuses

web_log_apache_vhosts.response_statuses



RESPONSES


Web server responses by type. success includes 1xx, 2xx, 304 and 401, error
includes 5xx, redirect includes 3xx except 304, bad includes 4xx except 401,
other are all the other responses.
web_log_apache_vhosts.response_statuses

Web server responses by code family. According to the standards 1xx are
informational responses, 2xx are successful responses, 3xx are redirects
(although they include 304 which is used as "not modified"), 4xx are bad
requests, 5xx are internal server errors, other are non-standard responses,
unmatched counts the lines in the log file that are not matched by the plugin
(let us know if you have any unmatched).
web_log_apache_vhosts.response_codes

Number of responses for each response code individually.
web_log_apache_vhosts.detailed_response_codes



BANDWIDTH

Bandwidth of requests (received) and responses (sent). received requires an
extended log format (without it, the web server log does not have this
information). This chart may present unusual spikes, since the bandwidth is
accounted at the time the log line is saved by the web server, even if the time
needed to serve it spans across a longer duration. We suggest to use QoS (e.g.
FireQOS) for accurate accounting of the web server bandwidth.

Unique client IPs accessing the web server, within each data collection
iteration. If data collection is per second, this chart shows unique client IPs
per second.
web_log_apache_vhosts.clients

Unique client IPs accessing the web server since the last restart of netdata.
This plugin keeps in memory all the unique IPs that have accessed the web
server. On very busy web servers (several millions of unique IPs) you may want
to disable this chart (check /etc/netdata/python.d/web_log.conf).

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 sequencially download all the charts, to avoid
congesting network and server resources.
Please, do not print netdata dashboards on paper!

PREPARING DASHBOARD FOR PRINTING...

Please wait while we initialize and render all the charts on the dashboard.

The print dialog will appear as soon as we finish rendering the page.

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 transfered 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.
