5 And it still runs with 1.000+ git downloads... per day!
7 **[check what our users say about netdata](https://github.com/firehol/netdata/issues/148)**.
13 **Real-time performance monitoring, done right!**
15 This is the default dashboard of **netdata**:
17 - real-time, per second updates, snappy refreshes!
18 - 300+ charts out of the box, 2000+ metrics monitored!
19 - zero configuration, zero maintenance, zero dependencies!
21 Live demo: [http://netdata.firehol.org](http://netdata.firehol.org)

29 **netdata** is a highly optimized Linux daemon providing **real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web**!
31 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.
35 - **Stunning bootstrap dashboards**, out of the box
36 - **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)
37 - **Zero configuration** - you just install it and it autodetects everything
38 - **Zero dependencies**, it is its own web server for its static web files and its web API
39 - **Zero maintenance**, you just run it, it does the rest
40 - **Custom dashboards** that can be built using simple HTML (no javascript necessary)
41 - **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)
42 - **Embeddable**, it can run anywhere a Linux kernel runs and its charts can be embedded on your web pages too
46 ## What does it monitor?
48 This is what it currently monitors (most with zero configuration):
50 - **CPU usage, interrupts, softirqs and frequency** (total and per core)
52 - **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
54 - **Disks** (per disk: I/O, operations, backlog, utilization, etc)

58 - **Network interfaces** (per interface: bandwidth, packets, errors, drops, etc)
60 ![dsl0](https://cloud.githubusercontent.com/assets/2662304/14093128/4d566494-f554-11e5-8ee4-5392e0ac51f0.gif)
62 - **IPv4 networking** (bandwidth, packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets)
64 - **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)
66 - **netfilter / iptables Linux firewall** (connections, connection tracker events, errors, etc)
68 - **Linux anti-DDoS protection** (SYNPROXY metrics)
70 - **Processes** (running, blocked, forks, active, etc)
72 - **Entropy** (random numbers pool, using in cryptography)
74 - **NFS file servers**, v2, v3, v4 (I/O, cache, read ahead, RPC calls)
76 - **Network QoS** (yes, the only tool that visualizes network `tc` classes in realtime)
78 ![qos-tc-classes](https://cloud.githubusercontent.com/assets/2662304/14093004/68966020-f553-11e5-98fe-ffee2086fafd.gif)
80 - **Applications**, by grouping the process tree (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)
82 ![apps](https://cloud.githubusercontent.com/assets/2662304/14093565/67c4002c-f557-11e5-86bd-0154f5135def.gif)
84 - **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)
86 - **Apache web server** mod-status (v2.2, v2.4)
88 - **Nginx web server** stub-status
90 - **mySQL databases** (multiple servers, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, etc)
92 - **ISC Bind name server** (multiple servers, each showing: clients, requests, queries, updates, failures and several per view metrics)
94 - **Postfix email server** message queue (entries, size)
96 - **Squid proxy server** (clients bandwidth and requests, servers bandwidth and requests)
98 - **Hardware sensors** (temperature, voltage, fans, power, humidity, etc)
100 - **NUT UPSes** (load, charge, battery voltage, temperature, utility metrics, output metrics)
102 Any number of **SNMP devices** can be monitored, although you will need to configure these.
104 And you can extend it, by writing plugins that collect data from any source, using any computer language.

110 Read **[Why netdata?](https://github.com/firehol/netdata/wiki/Why-netdata%3F)**
116 Use our **[automatic installer](https://github.com/firehol/netdata/wiki/Installation)** to build and install it on your system
118 It should run on any Linux system. We have tested it on:
130 Check the **[netdata wiki](https://github.com/firehol/netdata/wiki)**.
135 You are looking at a version of the sources extracted directly from git.
136 If you want a version of the source package where `configure` and any
137 documentation has been built for you, please get an official
