> *New to netdata? Here is a live demo: [http://my-netdata.io](http://my-netdata.io)*
**netdata** is a system for **distributed real-time performance and health monitoring**.
(**physical** & **virtual** servers, **containers**, **IoT** devices), without
disrupting their core function._
+netdata runs on **Linux**, **FreeBSD**, and **MacOS**.

- - improved plugins: mysql, cgroups, hddtemp, sensors, phpfm, tc (QoS)
+ - netdata now runs on **FreeBSD** and **MacOS**
+ - netdata now supports **Graphite**, **OpenTSDB**, **Prometheus** and compatible backends
+ - netdata now monitors **systemd Services**
+ - new plugins: fping, postgres, varnish, elasticsearch, haproxy, freeradius, mdstat, ISC dhcpd, fail2ban, openvpn, NUMA memory, CPU Idle States, gunicorn, ECC memory errors, IPC semaphores, uptime
+ - improved plugins: netfilter conntrack, mysql/mariadb, ipfs, cpufreq, hddtemp, sensors, nginx, nginx_log, phpfpm, redis, dovecot, containers and cgroups, disk space, apps.plugin, tc (QoS) and almost all internal plugins (memory, IPv4 and IPv6, network interfaces, QoS, etc)
+ - dozens of new and improved alarms (including performance monitoring alarms for mysql)
+ - new alarm notifications: messagebird.com, pagerduty.com, pushbullet.com, twilio.com, hipchat, kafka
+ - dozens more improvements and performance optimizations
---
with just 1% CPU utilization of a single core, a few MB of RAM and no disk I/O at all
- **Sophisticated alarming**<br/>
+ hundreds of alarms, **out of the box**!<br/>
supports dynamic thresholds, hysteresis, alarm templates,
multiple role-based notification methods (such as email, slack.com,
- pushover.net, pushbullet.com telegram.org, twilio.com, messagebird.com)
+ pushover.net, pushbullet.com, telegram.org, twilio.com, messagebird.com)
- **Extensible**<br/>
you can monitor anything you can get a metric for,
- **scales to infinity**<br/>
requiring minimal central resources
- - **back-ends supported**<br/>
- can archive its metrics on `graphite` or `opentsdb`, in the same or lower detail
+ - **several operating modes**<br/>
+ autonomous host monitoring, headless data collector, forwarding proxy, store and forward proxy, central multi-host monitoring, in all possible configurations.
+ Each node may have different metrics retention policy and run with or without health monitoring.
+
+ - **time-series back-ends supported**<br/>
+ can archive its metrics on `graphite`, `opentsdb`, `prometheus`, json document DBs, in the same or lower detail
(lower: to prevent it from congesting these servers due to the amount of data collected)
## What does it monitor?
-netdata monitors several thousands of metrics per device.
+netdata collects several thousands of metrics per device.
All these metrics are collected and visualized in real-time.
> _Almost all metrics are auto-detected, without any configuration._
This is a list of what it currently monitors:
- **CPU**<br/>
- usage, interrupts, softirqs, frequency, total and per core
+ usage, interrupts, softirqs, frequency, total and per core, CPU states
