# netdata #### 230.000+ views, 62.000+ visitors, 18.500+ downloads, 9.500+ github stars, 500+ forks, 14 days! And it still runs with 700+ git downloads... per day! **[Check what our users say about netdata](https://github.com/firehol/netdata/issues/148)**. Thank you! --- **Real-time performance monitoring, done right!** This is the default dashboard of **netdata**: - real-time, per second updates, snappy refreshes! - 300+ charts out of the box, 2000+ metrics monitored! - zero configuration, zero maintenance, zero dependencies! Live demo: [http://netdata.firehol.org](http://netdata.firehol.org) ![netdata](https://cloud.githubusercontent.com/assets/2662304/14092712/93b039ea-f551-11e5-822c-beadbf2b2a2e.gif) --- ## Features **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) - **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 autodetects everything - **Zero dependencies**, 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 - **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 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? 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, etc) ![sda](https://cloud.githubusercontent.com/assets/2662304/14093195/c882bbf4-f554-11e5-8863-1788d643d2c0.gif) - **Network interfaces** (per interface: bandwidth, packets, errors, drops, etc) ![dsl0](https://cloud.githubusercontent.com/assets/2662304/14093128/4d566494-f554-11e5-8ee4-5392e0ac51f0.gif) - **IPv4 networking** (bandwidth, packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets) - **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) - **netfilter / iptables Linux firewall** (connections, connection tracker events, errors, etc) - **Linux anti-DDoS protection** (SYNPROXY metrics) - **Processes** (running, blocked, forks, active, etc) - **Entropy** (random numbers pool, using in cryptography) - **NFS file servers**, 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) - **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) - **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) - **Apache web server** mod-status (v2.2, v2.4) - **Nginx web server** stub-status - **mySQL databases** (multiple servers, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, etc) - **ISC Bind name server** (multiple servers, each showing: clients, requests, queries, updates, failures and several per view metrics) - **Postfix email server** message queue (entries, size) - **Squid proxy server** (clients bandwidth and requests, servers bandwidth and requests) - **Hardware sensors** (temperature, voltage, fans, power, humidity, etc) - **NUT UPSes** (load, charge, battery voltage, temperature, utility metrics, output metrics) - **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. --- ## Still not convinced?
