+ <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> is the fastest way to visualize metrics. It is a resource efficient, highly optimized system for collecting and visualizing any type of realtime timeseries data, from CPU usage, disk activity, SQL queries, API calls, web site visitors, etc.
+ </div>
+ <div class="p">
+ <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> tries to visualize the truth of <b>now</b>, in its <b>greatest detail</b>, so that you can get insights of what is happening now and what just happened, on your systems and applications.
+ </div>
+ <div class="p">
+ To make a chart in <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>, you just need a <b>number</b>. Just a number you can read somehow. <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> will turn this number to a real time, interactive, web chart. For collecting these numbers, it supports <a href="https://github.com/firehol/netdata/wiki/External-Plugins" target="_blank">external plugins</a>, even <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">shell</a> or <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">node.js</a> plugins. Any computer program, in any language, that can print a few lines of text on its standard output, can be a netdata data collector.
+ </div>
+ <div class="p">
+ <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> can embed charts everywhere, like this one <div data-netdata="system.cpu" data-dimensions="system" data-after="-120" data-width="25%" data-height="15px" data-chart-library="dygraph" data-dygraph-theme="sparkline" data-show-value-of-system-at="system.cpu.system.modal.1"></div> (my CPU system usage which is <span id="system.cpu.system.modal.1" style="display: inline-block; width: 40px; text-align: right;"></span>%),

+ <div class="p">
+ You can have <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> charts on your site too. Just give it a <code>div</code> and a real time chart, zoomable and draggable will appear (try it even on these tiny ones - <b>drag</b> them to pan horizontally, <b>shift + drag</b> to zoom in, on <b>chrome shift + mouse wheel</b> to zoom in/out, <b>double click</b> on them to reset them - don't be afraid of <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> performance - <a href="https://github.com/firehol/netdata/wiki/Performance" target="_blank">a raspberry pi 2 can sustain 300 charts updates per second</a>!).

They only include values for the processes running. If an application is spawning childs continiously, which are terminated in just a few milliseconds (like shell scripts do), the values reported will be inaccurate. Linux does report the values for the exited childs of a process. However, these values are reported to the parent process <b>only when the child exits</b>. If these values, of the exited child processes, were also aggregated in the charts below, the charts would have been full of spikes, presenting unrealisting utilization for each process group. So, we decided to ignore these values and present only the utilization of <b>the currently running processes</b>.',
