**Real-time performance and health 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!
- dozens of health monitoring alarms, out of the box!
Live demo: [http://my-netdata.io](http://my-netdata.io)

## 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 (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 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
---
## 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)
- **Network interfaces** (per interface: bandwidth, packets, errors, drops, etc)
- **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 DDoS protection** (SYNPROXY metrics)
- **Processes** (running, blocked, forks, active, 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)
- **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)
- **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 servers** mod-status (v2.2, v2.4) and cache log statistics (multiple servers - compatible with lighttpd too)
- **Nginx web servers** stub-status (multiple servers)
- **mySQL databases** (multiple servers, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, etc)
- **Redis databases** (multiple servers, each showing: operations, hit rate, memory, keys, clients, slaves)
- **memcached databases** (multiple servers, each showing: bandwidth, connections, items, etc)
- **ISC Bind name servers** (multiple servers, each showing: clients, requests, queries, updates, failures and several per view metrics)
- **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.
