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 and 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):
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 -
Amazingly fast
responds to all queries in less than 0.5 ms per metric, even on low-end hardware -
Highly efficient
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 email, slack.com, pushover.net, pushbullet.com telegram.org, twilio.com) -
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 -
Customizable
custom dashboards can be built using simple HTML (no javascript necessary) -
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 -
scales to infinity
requiring minimal central resources -
back-ends supported
can archive its metrics ongraphite
oropentsdb
, in the same or lower detail (lower: to prevent it from congesting these servers due to the amount of data collected)
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 -
Interprocess Communication - IPC
such as semaphores and semaphores arrays -
netfilter / iptables Linux firewall
connections, connection tracker events, errors -
Linux DDoS protection
SYNPROXY metrics -
fping latencies
for any number of hosts, showing latency, packets and packet loss -
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 -
Postres databases
multiple servers, each showing: per database statistics (connections, tuples read - written - returned, transactions, locks), backend processes, indexes, tables, write ahead, background writer 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) -
Dovecot POP3/IMAP servers
-
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
