netdata is 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:

Stunning bootstrap dashboards , out of the box (themable: dark, light)

, out of the box (themable: dark, light) Blazingly fast and super efficient , mostly written in C (for default installations, expect just 2% of a single core CPU usage and a few MB of RAM)

and , mostly written in C (for default installations, expect just 2% of a single core CPU usage and a few MB of RAM) Zero configuration - you just install it and it autodetects everything

- you just install it and it autodetects everything Zero dependencies , it is its own web server for its static web files and its web API

, it is its own web server for its static web files and its web API Zero maintenance , you just run it, it does the rest

, you just run it, it does the rest Custom dashboards that can be built using simple HTML (no javascript necessary)

that can be built using simple HTML (no javascript necessary) 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, so you can easily monitor any application, any API)

, 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, so you can easily monitor any application, any API) Embeddable , it can run anywhere a Linux kernel runs and its charts can be embedded on your web pages too

What does it monitor?

CPU usage, interrupts, softirqs and frequency (total and per core)



(total and per core) RAM, swap and kernel memory usage (including KSM and kernel memory deduper)



(including KSM and kernel memory deduper) Disks (per disk: I/O, operations, backlog, utilization, etc)

(random numbers pool, using in cryptography) NFS file servers , v2, v3, v4 (I/O, cache, read ahead, RPC calls)



, v2, v3, v4 (I/O, cache, read ahead, RPC calls) Network QoS (yes, the only tool that visualizes network tc classes in realtime)





(yes, the only tool that visualizes network classes in realtime) Linux Control Groups (containers), systemd, lxc, docker, etc



(containers), systemd, lxc, docker, etc Applications , by grouping the process tree (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)





, by grouping the process tree (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc) Users and User Groups resource usage , by summarizing the process tree per user and group (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)



, by summarizing the process tree per user and group (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc) Apache web server mod-status (v2.2, v2.4)
