> *New to netdata? Here is a live demo: [http://my-netdata.io](http://my-netdata.io)*
**netdata** is a system for **real-time performance and health monitoring**! It provides **unparalleled insights, in real-time, with interactive web dashboards**, of everything happening on the system it runs, including supported applications.
_netdata is designed to permanently run on all systems (**physical** & **virtual** servers, **containers**, **IoT** devices), without disrupting the applications running on them._

</p>
- is **blazingly performance data visualization** - it responds to all queries in less than 0.5 ms per metric, even on low-end hardware!
- is **highly efficient performance data collector** - it collects thousands of metrics per server per second, with just 1% CPU utilization of a single core on modern hardware!
- has a **sophisticated alarming engine** - supporting dynamic thresholds, hysteresis, templating, multiple notification methods!
- out of the box collects **2000+ metrics**!
- needs **no configuration** - it auto-detects everything!
- needs **zero maintenance**!
- has **zero dependencies** - it is even its own web server!
- **scales to infinity**, requiring minimal central resources!

## Features
This is what you get:
- **Stunning bootstrap dashboards**, out of the box (theme-able: 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)
- **Zero configuration** - you just install it and it auto-detects everything
- **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)
- **Extensible**, you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin - from BASH to python and node.js, so you can easily monitor any application, any API)
- **Embeddable**, it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too
- **Powerful alarms and notifications**, it can send alarms as email, slack.com messages, pushover.net mobile push notifications, telegram.org messages, and more.
---
## What does it monitor?
This is what it currently monitors (most with zero configuration):
- **CPU usage, interrupts, softirqs and frequency** (total and per core)
- **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
- **Disks** (per disk: I/O, operations, backlog, utilization, space, etc)

- **Entropy** (random numbers pool, using in cryptography)
- **NFS file servers and clients**, v2, v3, v4 (I/O, cache, read ahead, RPC calls)
- **Network QoS** (yes, the only tool that visualizes network `tc` classes in realtime)
![qos-tc-classes](https://cloud.githubusercontent.com/assets/2662304/14093004/68966020-f553-11e5-98fe-ffee2086fafd.gif)
- **Linux Control Groups** (containers), systemd, lxc, docker, etc
- **Applications**, by grouping the process tree (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)
![apps](https://cloud.githubusercontent.com/assets/2662304/14093565/67c4002c-f557-11e5-86bd-0154f5135def.gif)

- **Redis databases** (multiple servers, each showing: operations, hit rate, memory, keys, clients, slaves)
- **memcached databases** (multiple servers, each showing: bandwidth, connections, items, etc)

- **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, etc)
- **NUT and APC UPSes** (load, charge, battery voltage, temperature, utility metrics, output metrics)
- **Tomcat** (accesses, threads, free memory, volume)
- **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.
