-**Real-time performance monitoring, done right!**
+> New to netdata? Live demo: [http://my-netdata.io](http://my-netdata.io)
-
+**netdata** is a highly optimized Linux daemon providing **real-time performance and health monitoring for Linux systems, applications and SNMP devices, over the web**! It has been designed to permanently run on all systems, without disrupting the applications running on them.

+**netdata** visualizes 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:
+
+ - real-time, per second updates, snappy refreshes!
+ - 300+ charts out of the box, 2000+ metrics monitored!
+ - zero configuration, zero maintenance, zero dependencies!
+ - dozens of health monitoring alarms, out of the box!

+## Features
This is what you get:
-1. **Beautiful out of the box** bootstrap dashboards
-2. **Custom dashboards** that can be built using simple HTML (no javascript necessary)
-3. **Blazingly fast** and **super efficient**, written in C (for default installations, expect just 2% of a single core CPU usage and a few MB of RAM)
-3. **Zero configuration** - you just install it and it autodetects everything
-4. **Zero dependencies**, it is its own web server for its static web files and its web API
-4. **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)
-7. **Embeddable**, it can run anywhere a Linux kernel runs
+- **Stunning bootstrap dashboards**, out of the box (theme-able: dark, light)
+- **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)
+- **Zero configuration** - you just install it and it auto-detects everything

+- **Extensible**, you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin - from BASH to python and node.js, so you can easily monitor any application, any API)
+- **Embeddable**, it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too
+- **Powerful alarms and notifications**, it can send alarms as email, slack.com messages, pushover.net mobile push notifications, telegram.org messages, and more.

-## What it monitors?
+## What does it monitor?
This is what it currently monitors (most with zero configuration):
-1. **CPU usage, interrupts, softirqs and frequency** (total and per core)
-2. **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
-3. **Disk I/O** (per disk: bandwidth, operations, backlog, utilization, etc)
