Netdata – linux performance monitoring, done right

Features

netdatais a highly optimized Linux daemon providing real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web !

It tries to visualize the truth of now , in its greatest detail , so that you can get insights of what is happening now and what just happened, on your systems and applications.

This is what you get:

  1. Beautiful out of the box bootstrap dashboards
  2. Custom dashboards that can be built using simple HTML (no javascript necessary)
  3. Blazingly fast and super efficient , written in C (for default installations, expect just 2% of a single core CPU usage and a few MB of RAM)
  4. Zero configuration – you just install it and it autodetects everything
  5. Zero dependencies , it is its own web server for its static web files and its web API
  6. Extensible , you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin – from BASH to node.js)
  7. Embeddable , it can run anywhere a Linux kernel runs

What is monitors?

This is what it currently monitors (most with zero configuration):

  1. CPU usage, interrupts, softirqs and frequency (total and per core)
  2. RAM, swap and kernel memory usage (including KSM and kernel memory deduper)
  3. Disk I/O(per disk: bandwidth, operations, backlog, utilization, etc)

  4. Network interfaces(per interface: bandwidth, packets, errors, drops, etc)

  5. IPv4 networking(packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets)

  6. netfilter / iptables Linux firewall (connections, connection tracker events, errors, etc)
  7. Processes (running, blocked, forks, active, etc)
  8. Entropy
  9. NFS file servers , v2, v3, v4 (I/O, cache, read ahead, RPC calls)
  10. Network QoS(yes, the only tool that visualizes network tc classes in realtime)

  11. Applications, by grouping the process tree (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)

  12. Apache web servermod-status (v2.2, v2.4)

  13. Nginx web server stub-status
  14. mySQL databases (multiple servers, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, etc)
  15. ISC Bind name server (multiple servers, each showing: clients, requests, queries, updates, failures and several per view metrics)
  16. Postfix email server message queue (entries, size)
  17. Squid proxy server (clients bandwidth and requests, servers bandwidth and requests)
  18. Hardware sensors (temperature, voltage, fans, power, humidity, etc)
  19. NUT UPSes (load, charge, battery voltage, temperature, utility metrics, output metrics)

Any number of SNMP devices can be monitored, although you will need to configure these.

And you can extend it, by writing plugins that collect data from any source, using any computer language.
