421 <div class="modal-body">
423 <b><a href="https://github.com/firehol/netdata/" target="_blank">netdata</a></b> is the fastest way to visualize data. 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, to web site visitors, e-shop orders, revenue and profits.
426 To make a chart in <b><a href="https://github.com/firehol/netdata/" 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/" target="_blank">netdata</a></b> will turn this number to a real time web chart. For collecting these numbers, it supports <a href="https://github.com/firehol/netdata/tree/master/plugins.d" target="_blank">external plugins</a>, even <a href="https://github.com/firehol/netdata/tree/master/charts.d" target="_blank">bash shell plugins</a>. Any computer program, in any language, that can print a few lines of text on its standard output, can be a netdata data collector.
429 <b><a href="https://github.com/firehol/netdata/" 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>%),
430 or this one <div data-netdata="ipv4.tcppackets" data-dimensions="received" data-after="-120" data-width="25%" data-height="15px" data-chart-library="dygraph" data-dygraph-theme="sparkline" data-show-value-of-received-at="ipv4.tcppackets.received.modal.1"></div> (my IPv4 received TCP packets, which are <span id="ipv4.tcppackets.received.modal.1" style="display: inline-block; width: 60px; text-align: right;"></span>/second).
433 You can have <b><a href="https://github.com/firehol/netdata/" 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/" target="_blank">netdata</a></b> performance - <a href="https://github.com/firehol/netdata/issues/36" target="_blank">a raspberry pi 2 can sustain 300 charts updates per second</a>!).
436 If you like this project, <b>we need help writing documentation, coding plugins, testing new features, supporting end users.</b>
439 We will be glad to have you on board...

508 <small>When set to <b>parallel</b>, visible charts are refreshed in parallel (all queries are sent to netdata server in parallel) and are rendered asynchronously.

521 <small>When set to <b>Resync</b>, the dashboard will attempt to re-synchronize all the charts so that they are refreshed concurrently. When set to <b>Best Effort</b>, each chart may be refreshed with a little time difference to the others. Normally, the dashboard starts refreshing them in parallel, but depending on the speed of your computer and the network latencies, charts start having a slight time difference. Setting this to <b>Resync</b> will attempt to re-synchronize the charts on every update. Setting it to <b>Best Effort</b> may lower the pressure on your browser and the network.</small>

If you also use <a href="http://firehol.org/#fireqos" target="_blank">FireQOS</a> for setting up QoS, netdata automatically collects interface and class names. If your QoS configuration includes overheads calculation, the values shown here will include these overheads (the total bandwidth for the same interface as reported in the Network Interfaces section, will be lower than the total bandwidth reported here). Also, data collection may have a slight time difference compared to the interface (QoS data collection is implemented with a BASH script, so a shift in data collection of a few milliseconds should be justified).',

The plugin internaly builds a process tree (much like <code>ps fax</code> does), and groups processes together (evaluating both child and parent processes) so that the result is always a chart with a predefined set of dimensions (of course, only application groups found running are reported).<br/><b>IMPORTANT</b>: The values shown here are not 100% accurate. 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.
