+> *New to netdata? Here is a live demo: [http://my-netdata.io](http://my-netdata.io)*
-And it still runs with 600+ git downloads... per day!
+**netdata** is an application for **real-time performance and health monitoring**. It provides **unparalleled insights, in real-time**, of everything happening on the system it runs (including key applications such as web and database servers), using **modern interactive web dashboards**.
-**[Check what our users say about netdata](https://github.com/firehol/netdata/issues/148)**.

-Thank you!
+_netdata is **very fast** and **super efficient**, designed to permanently run on all systems (**physical** & **virtual** servers, **containers**, **IoT** devices), without disrupting their core function._

-## Features
+`Oct 4th, 2016` - **[netdata v1.4.0 released!](https://github.com/firehol/netdata/releases)**
-**netdata** is a highly optimized Linux daemon providing **real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web**!
+ - the **fastest** netdata ever (with a better look too)!
+ - improved **IoT** and **containers** support!
+ - **alarms** improved in almost every way!
+ - new plugins: softnet netdev, extended TCP metrics, UDPLite, NFS v2, v3 client (server was there already), NFS v4 server & client, APCUPSd, RetroShare
+ - improved plugins: mysql, cgroups, hddtemp, sensors, phpfm, tc (QoS)
-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.

+
+ - **Stunning interactive bootstrap dashboards**<br/>2 themes are provided: dark, light
+ - **Blazingly fast visualization**<br/>responds to all queries in less than 0.5 ms per metric, even on low-end hardware
+ - **Highly efficient data collection**<br/>collects thousands of metrics per server per second, with just 1% CPU utilization of a single core on modern hardware
+ - **Sophisticated alarming**<br/>supports dynamic thresholds, hysteresis, templating, multiple notification methods
+ - **Extensible**<br/>you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin, BASH, python, perl, node.js, java, Go, etc)
+ - **Zero configuration**<br/>auto-detects everything, out of the box it can collect up to 5000 metrics per server
+ - **Zero dependencies**<br/>it is even its own web server, for its static web files and its web API
+ - **Zero maintenance**<br/>you just run it, it does the rest
+ - **Embeddable**<br/>it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too
+ - **Custom dashboards**<br/>that can be built using simple HTML (no javascript necessary)
+ - **scales to infinity**<br/>requiring minimal central resources!
-- **Stunning bootstrap dashboards**, out of the box (themable: 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 autodetects everything
-- **Zero dependencies**, it is its own web server for its static web files and its web API
-- **Zero maintenance**, you just run it, it does the rest
-- **Custom dashboards** that can be built using simple HTML (no javascript necessary)
-- **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)
