New to netdata? Here is a live demo: http://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.
User base
Since May 16th 2016 (the date the global public netdata registry was released):
News
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)
Features
-
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
What does it monitor?
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 networktc
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.
