**netdata** is a system for **distributed real-time performance and health monitoring**.
It provides **unparalleled insights, in real-time**, of everything happening on the
-system it runs (including applications such as web, or database servers), using
+system it runs (including applications such as web and database servers), using
**modern interactive web dashboards**.
_netdata is **fast** and **efficient**, designed to permanently run on all systems
- **Stunning interactive bootstrap dashboards**<br/>
mouse and touch friendly, in 2 themes: dark, light
- - **Blazingly fast**<br/>
+ - **Amazingly fast**<br/>
responds to all queries in less than 0.5 ms per metric,
- even on low-end hardware (such as a raspberry pi 1)
+ even on low-end hardware
- - **Highly efficient data collection**<br/>
+ - **Highly efficient**<br/>
collects thousands of metrics per server per second,
with just 1% CPU utilization of a single core, a few MB or RAM and no disk I/O at all
- **Sophisticated alarming**<br/>
supports dynamic thresholds, hysteresis, alarm templates,
- multiple role-based notification methods (such as slack.com, pushover.net, telegram.org, email)
+ multiple role-based notification methods (such as email, slack.com,
+ pushover.net, pushbullet.com telegram.org, twilio.com)
- **Extensible**<br/>
you can monitor anything you can get a metric for,
it can run anywhere a Linux kernel runs (even IoT)
and its charts can be embedded on your web pages too
+ - **Customizable**<br/>
+ custom dashboards can be built using simple HTML (no javascript necessary)
+
- **Zero configuration**<br/>
auto-detects everything, it can collect up to 5000 metrics
per server out of the box
- **Zero maintenance**<br/>
you just run it, it does the rest
- - **Custom dashboards**<br/>
- that can be built using simple HTML (no javascript necessary)
-
- **scales to infinity**<br/>
requiring minimal central resources
+
+ - **back-ends supported**<br/>
+ can archive its metrics on `graphite` or `opentsdb`, in the same or lower detail
+ (lower: to prevent it from congesting these servers due to the amount of data collected)
