> *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**.

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)
- **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
- **Memory**<br/>
RAM, swap and kernel memory usage, KSM (Kernel Samepage Merging), NUMA
- **Disks**<br/>
- per disk: I/O, operations, backlog, utilization, space
+ per disk: I/O, operations, backlog, utilization, space, software RAID (md)
- **Tomcat**<br/>
accesses, threads, free memory, volume
+- **web server log files**<br/>
+ extracting in real-time, web server performance metrics and applying several health checks
