New to netdata? Here is a live demo: https://my-netdata.io

netdata is a system for distributed real-time performance and health monitoring. It provides unparalleled insights, in real-time, of everything happening on the system it runs (including applications such as web, or database servers), using modern interactive web dashboards.

netdata is fast and efficient, designed to permanently run on all systems (physical & virtual servers, containers, IoT devices), without disrupting their core function.

Since May 16th 2016 (the date the global public netdata registry was released):

in the last 24 hours:

Oct 4th, 2016 - netdata v1.4.0 released!

• the fastest netdata ever (with a better look too)
• improved IoT and containers support
• alarms improved in almost every way
• new plugins: softnet netdev, extended TCP metrics, UDPLite, NFS v2, v3 client (server was there already), NFS v4 server & client, APCUPSd, RetroShare
• improved plugins: mysql, cgroups, hddtemp, sensors, phpfm, tc (QoS)

• Stunning interactive bootstrap dashboards
  mouse and touch friendly, in 2 themes: dark, light

• Blazingly fast
  responds to all queries in less than 0.5 ms per metric, even on low-end hardware (such as a raspberry pi 1)

• Highly efficient data collection
  collects thousands of metrics per server per second, with just 1% CPU utilization of a single core, a few MB or RAM and no disk I/O at all

• Sophisticated alarming
  supports dynamic thresholds, hysteresis, alarm templates, multiple role-based notification methods (such as slack.com, pushover.net, telegram.org, email)

• Extensible
  you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin, BASH, python, perl, node.js, java, Go, ruby, etc)

• Embeddable
  it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too

• Zero configuration
  auto-detects everything, it can collect up to 5000 metrics per server out of the box

• Zero dependencies
  it is even its own web server, for its static web files and its web API

• Zero maintenance
  you just run it, it does the rest

• Custom dashboards
  that can be built using simple HTML (no javascript necessary)

• scales to infinity
  requiring minimal central resources

netdata monitors several thousands of metrics per device. All these metrics are collected and visualized in real-time.

Almost all metrics are auto-detected, without any configuration.

This is a list of what it currently monitors:

• CPU
  usage, interrupts, softirqs, frequency, total and per core

• Memory
  RAM, swap and kernel memory usage, including KSM the kernel memory deduper

• Disks
  per disk: I/O, operations, backlog, utilization, space

  

• Network interfaces
  per interface: bandwidth, packets, errors, drops

  

• IPv4 networking
  bandwidth, packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets

• IPv6 networking
  bandwidth, packets, errors, fragments, ECT, udp: packets, errors, udplite: packets, errors, broadcast: bandwidth, multicast: bandwidth, packets, icmp: messages, errors, echos, router, neighbor, MLDv2, group membership, break down by type

• netfilter / iptables Linux firewall
  connections, connection tracker events, errors

• Linux DDoS protection
  SYNPROXY metrics

• Processes
  running, blocked, forks, active

• Entropy
  random numbers pool, using in cryptography

• NFS file servers and clients
  NFS v2, v3, v4: I/O, cache, read ahead, RPC calls

• Network QoS
  the only tool that visualizes network tc classes in realtime

  

• Linux Control Groups
  containers: systemd, lxc, docker

• Applications
  by grouping the process tree and reporting CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets - per group

  

• Users and User Groups resource usage
  by summarizing the process tree per user and group, reporting: CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets

• Apache and lighttpd web servers
  mod-status (v2.2, v2.4) and cache log statistics, for multiple servers

• Nginx web servers
  stub-status, for multiple servers

• Tomcat
  accesses, threads, free memory, volume

• mySQL databases
  multiple servers, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, and more

• Redis databases
  multiple servers, each showing: operations, hit rate, memory, keys, clients, slaves

• memcached databases
  multiple servers, each showing: bandwidth, connections, items

• ISC Bind name servers
  multiple servers, each showing: clients, requests, queries, updates, failures and several per view metrics

• Postfix email servers
  message queue (entries, size)

• exim email servers
  message queue (emails queued)

• IPFS
  bandwidth, peers

• Squid proxy servers
  multiple servers, each showing: clients bandwidth and requests, servers bandwidth and requests

• Hardware sensors
  temperature, voltage, fans, power, humidity

• NUT and APC UPSes
  load, charge, battery voltage, temperature, utility metrics, output metrics

• PHP-FPM
  multiple instances, each reporting connections, requests, performance

• hddtemp
  disk temperatures

• SNMP devices
  can be monitored too (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.

Use our automatic installer to build and install it on your system.

It should run on any Linux system (including IoT). It has been tested on:

• Alpine
• Arch Linux
• CentOS
• Debian
• Fedora
• Gentoo
• OpenSuse
• PLD Linux
• RedHat Enterprise Linux
• SUSE
• Ubuntu
