  38 **Real-time performance monitoring, done right!**
  39
  40 This is the default dashboard of **netdata**:
  41
  42  - real-time, per second updates, snappy refreshes!
  43  - 300+ charts out of the box, 2000+ metrics monitored!
  44  - zero configuration, zero maintenance, zero dependencies!

  52 ## Features
  53
  54 **netdata** is a highly optimized Linux daemon providing **real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web**!
  55
  56 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.
  57
  58 This is what you get:
  59
  60 - **Stunning bootstrap dashboards**, out of the box (themable: dark, light)
  61 - **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)
  62 - **Zero configuration** - you just install it and it autodetects everything
  63 - **Zero dependencies**, it is its own web server for its static web files and its web API
  64 - **Zero maintenance**, you just run it, it does the rest
  65 - **Custom dashboards** that can be built using simple HTML (no javascript necessary)
  66 - **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)
  67 - **Embeddable**, it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too

  71 ## What does it monitor?
  72
  73 This is what it currently monitors (most with zero configuration):
  74
  75 - **CPU usage, interrupts, softirqs and frequency** (total and per core)
  76
  77 - **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
  78
  79 - **Disks** (per disk: I/O, operations, backlog, utilization, space, etc)
