  49 ## Features
  50
  51 **netdata** is a highly optimized Linux daemon providing **real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web**!
  52
  53 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.
  54
  55 This is what you get:
  56
  57 - **Stunning bootstrap dashboards**, out of the box (themable: dark, light)
  58 - **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)
  59 - **Zero configuration** - you just install it and it autodetects everything
  60 - **Zero dependencies**, it is its own web server for its static web files and its web API
  61 - **Zero maintenance**, you just run it, it does the rest
  62 - **Custom dashboards** that can be built using simple HTML (no javascript necessary)
  63 - **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)
  64 - **Embeddable**, it can run anywhere a Linux kernel runs and its charts can be embedded on your web pages too

  68 ## What does it monitor?
  69
  70 This is what it currently monitors (most with zero configuration):

  73
  74 - **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
