425 <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.
428 <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.
431 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/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.
434 <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>%),
435 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).
438 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/issues/36" target="_blank">a raspberry pi 2 can sustain 300 charts updates per second</a>!).

472 <h4>Mouse Over / Hover</h4>
473 Mouse over on a chart to show, at its legend, the values for the timestamp under the mouse (the chart will also highlight the point at the chart).
475 All the other visible charts will also show and highlight their values for the same timestamp.
479 <h4>Trag Chart Contents</h4>
480 Trag the contents of a chart to pan it horizontally.
482 All the charts will follow soon after you let the chart alone (this little delay is by design: it speeds up your browser and lets you focus on what you are exploring).
484 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double click</b> a panned chart.
488 <h4>Double Click</h4>
489 Double Click a chart to reset all the charts to their default auto-refreshing state.
493 <h4>SHIFT + Trag</h4>
494 While pressing the shift key, select with the mouse and area of a chart, to zoom in. The other charts will follow too. Zooming is performed in two phases:
496 <li>The already loaded chart contents are zoomed (low resolution)</li>
497 <li>New data are transfered from the netdata server, to refresh the chart with possibly more detail.</li>
499 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
503 <h4>SHIFT + Mouse Wheel <small>(does not work on firefox and IE/Edge)</small></h4>
504 While pressing the shift key and the mouse pointer is over the contents of a chart, scroll the mouse wheel to zoom in or out. This kind of zooming is aligned to center below the mouse pointer. The other charts will follow too.
506 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
510 <h4>Legend Operations</h4>
511 Click on the label or value of a dimension, will select / unselect this dimension.
513 You can press any of the shift or control keys and the click on legend labels or values, to select / unselect multiple dimensions.
516 <div role="tabpanel" class="tab-pane" id="help_touch">
519 Single Tap on the contents of a chart to show, at its legend, the values for the timestamp tapped (the chart will also highlight the point at the chart).

526 Touch and Trag the contents of a chart to pan it horizontally.

530 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double tap</b> a panned chart.

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).
