\n\n - **Stunning interactive bootstrap dashboards**
\n mouse and touch friendly, in 2 themes: dark, light\n\n - **Amazingly fast**
\n responds to all queries in less than 0.5 ms per metric,\n even on low-end hardware\n\n - **Highly efficient**
\n collects thousands of metrics per server per second,\n with just 1% CPU utilization of a single core, a few MB of RAM and no disk I/O at all\n\n - **Sophisticated alerting**
\n hundreds of alarms, **out of the box**!
\n supports dynamic thresholds, hysteresis, alarm templates,\n multiple role-based notification methods (such as email, slack.com, flock.com,\n pushover.net, pushbullet.com, telegram.org, twilio.com, messagebird.com, kavenegar.com)\n\n - **Extensible**
\n you can monitor anything you can get a metric for,\n using its Plugin API (anything can be a netdata plugin,\n BASH, python, perl, node.js, java, Go, ruby, etc)\n\n - **Embeddable**
\n it can run anywhere a Linux kernel runs (even IoT)\n and its charts can be embedded on your web pages too\n\n - **Customizable**
\n custom dashboards can be built using simple HTML (no javascript necessary)\n\n - **Zero configuration**
\n auto-detects everything, it can collect up to 5000 metrics\n per server out of the box\n\n - **Zero dependencies**
\n it is even its own web server, for its static web files and its web API\n\n - **Zero maintenance**
\n you just run it, it does the rest\n\n - **scales to infinity**
\n requiring minimal central resources\n\n - **several operating modes**
\n autonomous host monitoring, headless data collector, forwarding proxy, store and forward proxy, central multi-host monitoring, in all possible configurations.\n Each node may have different metrics retention policy and run with or without health monitoring.\n\n - **time-series back-ends supported**
\n can archive its metrics on `graphite`, `opentsdb`, `prometheus`, json document DBs, in the same or lower detail\n (lower: to prevent it from congesting these servers due to the amount of data collected)\n\n![netdata](https://cloud.githubusercontent.com/assets/2662304/14092712/93b039ea-f551-11e5-822c-beadbf2b2a2e.gif)\n\n---\n\n## What does it monitor?\n\nnetdata collects several thousands of metrics per device.\nAll these metrics are collected and visualized in real-time.\n\n> _Almost all metrics are auto-detected, without any configuration._\n\nThis is a list of what it currently monitors:\n\n- **CPU**
