18 > - **[netdata registry](https://github.com/firehol/netdata/wiki/mynetdata-menu-item)**, the first step towards scaling out performance monitoring!
19 > - real-time Linux Containers monitoring!
20 > - dozens of additional new features, optimizations, bug-fixes
26 ##### 320.000+ views, 92.000+ visitors, 28.500+ downloads, 11.000+ github stars, 700+ forks, 1 month!
28 And it still runs with 600+ git downloads... per day!
30 **[Check what our users say about netdata](https://github.com/firehol/netdata/issues/148)**.
34 **Real-time performance monitoring, done right!**
36 This is the default dashboard of **netdata**:
38 - real-time, per second updates, snappy refreshes!
39 - 300+ charts out of the box, 2000+ metrics monitored!
40 - zero configuration, zero maintenance, zero dependencies!
42 Live demo: [http://netdata.firehol.org](http://netdata.firehol.org)
44 ![netdata](https://cloud.githubusercontent.com/assets/2662304/14092712/93b039ea-f551-11e5-822c-beadbf2b2a2e.gif)
50 **netdata** is a highly optimized Linux daemon providing **real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web**!
52 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.
56 - **Stunning bootstrap dashboards**, out of the box (themable: dark, light)
57 - **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)
58 - **Zero configuration** - you just install it and it autodetects everything
59 - **Zero dependencies**, it is its own web server for its static web files and its web API
60 - **Zero maintenance**, you just run it, it does the rest
61 - **Custom dashboards** that can be built using simple HTML (no javascript necessary)
62 - **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)
63 - **Embeddable**, it can run anywhere a Linux kernel runs and its charts can be embedded on your web pages too
67 ## What does it monitor?
69 This is what it currently monitors (most with zero configuration):
71 - **CPU usage, interrupts, softirqs and frequency** (total and per core)
73 - **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
75 - **Disks** (per disk: I/O, operations, backlog, utilization, space, etc)
77 ![sda](https://cloud.githubusercontent.com/assets/2662304/14093195/c882bbf4-f554-11e5-8863-1788d643d2c0.gif)
79 - **Network interfaces** (per interface: bandwidth, packets, errors, drops, etc)
81 ![dsl0](https://cloud.githubusercontent.com/assets/2662304/14093128/4d566494-f554-11e5-8ee4-5392e0ac51f0.gif)
83 - **IPv4 networking** (bandwidth, packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets)
85 - **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)
87 - **netfilter / iptables Linux firewall** (connections, connection tracker events, errors, etc)
89 - **Linux DDoS protection** (SYNPROXY metrics)
91 - **Processes** (running, blocked, forks, active, etc)
93 - **Entropy** (random numbers pool, using in cryptography)
95 - **NFS file servers**, v2, v3, v4 (I/O, cache, read ahead, RPC calls)
97 - **Network QoS** (yes, the only tool that visualizes network `tc` classes in realtime)
99 ![qos-tc-classes](https://cloud.githubusercontent.com/assets/2662304/14093004/68966020-f553-11e5-98fe-ffee2086fafd.gif)
101 - **Linux Control Groups** (containers), systemd, lxc, docker, etc
103 - **Applications**, by grouping the process tree (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)
105 ![apps](https://cloud.githubusercontent.com/assets/2662304/14093565/67c4002c-f557-11e5-86bd-0154f5135def.gif)
107 - **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)
109 - **Apache web server** mod-status (v2.2, v2.4)
111 - **Nginx web server** stub-status
113 - **mySQL databases** (multiple servers, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, etc)
115 - **ISC Bind name server** (multiple servers, each showing: clients, requests, queries, updates, failures and several per view metrics)
117 - **Postfix email server** message queue (entries, size)
119 - **Squid proxy server** (clients bandwidth and requests, servers bandwidth and requests)
121 - **Hardware sensors** (temperature, voltage, fans, power, humidity, etc)
123 - **NUT UPSes** (load, charge, battery voltage, temperature, utility metrics, output metrics)
125 - **Tomcat** (accesses, threads, free memory, volume)
127 - **PHP-FPM** (multiple instances, each reporting connections, requests, performance)
129 - **SNMP devices** can be monitored too (although you will need to configure these)
131 And you can extend it, by writing plugins that collect data from any source, using any computer language.
