3 > *New to netdata? Here is a live demo: [http://my-netdata.io](http://my-netdata.io)*
5 **netdata** is a system for **real-time performance and health monitoring**!
6 It provides **unparalleled insights, in real-time, with interactive web dashboards**, of everything happening on the system it runs, including supported applications.
8 _netdata is designed to permanently run on all systems (**physical** & **virtual** servers, **containers**, **IoT** devices), without disrupting the applications running on them._
15 *Since May 16th 2016 (the time the [global public netdata registry](https://github.com/firehol/netdata/wiki/mynetdata-menu-item) was released):*<br/>

33 > - **alarms** improved in almost every way!
34 > - new plugins: softnet netdev, extended TCP metrics, UDPLite, NFS v2, v3 client (server was there already), NFS v4 server & client, APCUPSd, RetroShare
35 > - improved plugins: mysql, cgroups, hddtemp, sensors, phpfm, tc (QoS)

45 - **Stunning interactive bootstrap dashboards**, out of the box (theme-able: dark, light)
46 - **Blazingly fast visualization**, it responds to all queries in less than 0.5 ms per metric, even on low-end hardware
47 - **Highly efficient data collection**, it collects thousands of metrics per server per second, with just 1% CPU utilization of a single core on modern hardware
48 - **Sophisticated alarming**, supporting dynamic thresholds, hysteresis, templating, multiple notification methods
49 - **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, etc)
50 - **Zero configuration**, it auto-detects everything, out of the box it can detect up to 5000 metrics per server organized
51 - **Zero dependencies**, it is even its own web server for its static web files and its web API
52 - **Zero maintenance**, you just run it, it does the rest
53 - **Embeddable**, it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too
54 - **Custom dashboards**, that can be built using simple HTML (no javascript necessary)
55 - **scales to infinity**, requiring minimal central resources!

61 ## What does it monitor?
63 This is what it currently monitors (most with zero configuration):
65 - **CPU usage, interrupts, softirqs and frequency** (total and per core)
67 - **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
69 - **Disks** (per disk: I/O, operations, backlog, utilization, space, etc)

135 And you can extend it, by writing plugins that collect data from any source, using any computer language.
141 Use our **[automatic installer](https://github.com/firehol/netdata/wiki/Installation)** to build and install it on your system.
143 It should run on **any Linux** system (including IoT). It has been tested on:
153 - RedHat Enterprise Linux
