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

This is usually the total disk I/O of the system. system.pgpgio RAM System Random Access Memory (i.e. physical memory) usage. system.ram SWAP System swap memory usage. Swap space is used when the amount of physical memory (RAM) is full. When the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space (usually a disk, a disk partition or a file). system.swap System swap I/O. In - pages the system has swapped in from disk to RAM. Out - pages the system has swapped out from RAM to disk. system.swapio 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 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. show more information 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 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 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. system.shared_memory_bytes -------------------------------------------------------------------------------- CPUS Detailed information for each CPU of the system. A summary of the system for all CPUs can be found at the System Overview section. UTILIZATION cpu.cpu0 cpu.cpu1 SOFTNET Statistics for CPUs SoftIRQs related to network receive work. Total for all CPU cores can be found at System / 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). cpu.cpu0_softnet_stat cpu.cpu1_softnet_stat -------------------------------------------------------------------------------- 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 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.

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. / Disk space utilization. reserved for root is automatically reserved by the system to prevent the root user from getting out of space. disk_space._ Inodes (or index nodes) are filesystem objects (e.g. files and directories). On many types of file system implementations, the maximum number of inodes is fixed at filesystem creation, limiting the maximum number of files the filesystem can hold. It is possible for a device to run out of inodes. When this happens, new files cannot be created on the device, even though there may be free space available. disk_inodes._ /DEV Disk space utilization. reserved for root is automatically reserved by the system to prevent the root user from getting out of space. disk_space._dev Inodes (or index nodes) are filesystem objects (e.g. files and directories).

IPVS running on a host acts as a load balancer at the front of a cluster of real servers, it can direct requests for TCP/UDP based services to the real servers, and makes services of the real servers to appear as a virtual service on a single IP address. Netdata collects summary statistics, reading /proc/net/ip_vs_stats. To display the statistics information of services and their servers, run ipvsadm -Ln --stats or ipvsadm -Ln --rate for the rate statistics. For details, see ipvsadm(8). IPVS Total network traffic for all services and their servers. ipvs.net Total created connections for all services and their servers. To see the IPVS connection table, run ipvsadm -Lnc. ipvs.sockets Total transferred packets for all services and their servers. ipvs.packets -------------------------------------------------------------------------------- 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, sometimes it won't. Timeout - happens when a connection times out. Linger - happens when the kernel killed a socket that was already closed by the application and lingered around for long enough. Failed - happens when the kernel attempted to se... 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.

Timeout - happens when a connection times out. Linger - happens when the kernel killed a socket that was already closed by the application and lingered around for long enough. Failed - happens when the kernel attempted to send an RST but failed because there was no memory available. show more information ip.tcpconnaborts 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 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, e.g. bad ICMP checksums, bad length, etc. OutErrors - ICMP messages which this host did not send due to problems discovered within ICMP such as a lack of buffers. This counter does not include errors discovered outside the ICMP layer such as the inability of IP to route the resultant datagram. InCsumErrors - received ICMP messages with bad checksum. ipv4.icmp_errors The number of transferred IPv4 ICMP control messages. ipv4.icmpmsg TCP The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT. This is a snapshot of the established connections at the time of measurement (i.e. a connection established and a connection disconnected within the same iteration will not affect this metric). ipv4.tcpsock The number of TCP sockets in the system in certain states. Alloc - in any TCP state. Orphan - no longer attached to a socket descriptor in any user processes, but for which the kernel is still required to maintain state in order to complete the transport protocol. InUse - in any TCP state, excluding TIME-WAIT and CLOSED. TimeWait - in the TIME-WAIT state. ipv4.sockstat_tcp_sockets The number of packets transferred by the TCP layer. Received - received packets, including those received in error, such as checksum error, invalid TCP header, and so on. Sent - sent packets, excluding the retransmitted packets. But it includes the SYN, ACK, and RST packets. ipv4.tcppackets TCP connection statistics. Active - number of outgoing TCP connections attempted by this host. Passive - number of incoming TCP connections accepted by this host. ipv4.tcpopens TCP errors. InErrs - TCP segments received in error (including header too small, checksum errors, sequence errors, bad packets - for both IPv4 and IPv6). InCsumErrors - TCP segments received with checksum errors (for both IPv4 and IPv6). RetransSegs - TCP segments retransmitted. ipv4.tcperrors TCP handshake statistics. EstabResets - established connections resets (i.e. connections that made a direct transition from ESTABLISHED or CLOSE_WAIT to CLOSED). OutRsts - TCP segments sent, with the RST flag set (for both IPv4 and IPv6). AttemptFails - number of times TCP connections made a direct transition from either SYN_SENT or SYN_RECV to CLOSED, plus the number of times TCP connections made a direct transition from the SYN_RECV to LISTEN. SynRetrans - shows retries for new outbound TCP connections, which can indicate general connectivity issues or backlog on the remote host. ipv4.tcphandshake The amount of memory used by allocated TCP sockets. ipv4.sockstat_tcp_mem UDP The number of used UDP sockets. ipv4.sockstat_udp_sockets The number of transferred UDP packets. ipv4.udppackets The number of errors encountered during transferring UDP packets. RcvbufErrors - receive buffer is full. SndbufErrors - send buffer is full, no kernel memory available, or the IP layer reported an error when trying to send the packet and no error queue has been setup. InErrors - that is an aggregated counter for all errors, excluding NoPorts. NoPorts - no application is listening at the destination port. InCsumErrors - a UDP checksum failure is detected. IgnoredMulti - ignored multicast packets. ipv4.udperrors The amount of memory used by allocated UDP sockets. ipv4.sockstat_udp_mem -------------------------------------------------------------------------------- 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. ipv6.packets ERRORS The number of discarded IPv6 packets. InDiscards, OutDiscards - 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 - 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. ipv6.errors TCP6 The number of TCP sockets in any state, excluding TIME-WAIT and CLOSED. ipv6.sockstat6_tcp_sockets -------------------------------------------------------------------------------- NETWORK INTERFACES Performance metrics for network interfaces. Netdata retrieves this data reading the /proc/net/dev file and /sys/class/net/ directory. ETH0 net.eth0 net.eth0 The amount of traffic transferred by the network interface. net.eth0 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.eth0 -------------------------------------------------------------------------------- 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 -------------------------------------------------------------------------------- APPLICATIONS Per application statistics are collected using apps.plugin.

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. FilenameHostnameOrigin URLCharts InfoSnapshot InfoTime RangeComments Snapshot files contain both data and javascript code. Make sure you trust the files you import! Import Close × EXPORT A SNAPSHOT Please wait while we collect all the dashboard data... Select the desired resolution of the snapshot. This is the seconds of data per point. Filename Compression * Select Compression * * uncompressed * * pako.deflate (gzip, binary) * pako.deflate.base64 (gzip, ascii) * * lzstring.uri (LZ, ascii) * lzstring.utf16 (LZ, utf16) * lzstring.base64 (LZ, ascii) 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. Export Cancel × NETDATA ALARMS * Active * All * Log loading... loading... loading... Close × 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. Close × UPDATE CHECK Your netdata version: v1.35.0-123-nightly New version of netdata available!
