2788 if there is a metric for something, we want it visualised<br/>
2789 and we want this visualisation to be <strong>real-time</strong>, <strong>efficient</strong> and <strong>awesome</strong>
2793 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2794 is a new way to monitor your systems and applications, to get <strong>real-time insights</strong>
2795 of what is really happening and what affects performance.
2796 It is carefully optimised to be a real-time system, without interfering in any way,
2797 to the core function of your systems.
2800 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2801 has been designed to monitor <strong>massive amounts of metrics, per server, per second</strong>.
2802 When installed, it might come up with 1k to 3k metrics, but we have been testing it with 100k
2803 metrics, all collected per second, and still the cpu utilisation remained negligible.
2805 We have also tried to give each metric, a meaning, a context.
2806 We have grouped and categorized all metrics into meaningful charts, providing a
2807 better understanding of the underlying technologies and mechanisms.
2810 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> is free,
2811 open-source software. If you decide to use it,
2812 <strong><a href="https://github.com/firehol/netdata/wiki/a-github-star-is-important" target="_blank">it is important to give netdata a star at GitHub</a></strong>.

2849 <h4>Mouse Over / Hover</h4>
2850 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).
2852 All the other visible charts will also show and highlight their values for the same timestamp.
2856 <h4>Drag Chart Contents</h4>
2857 Drag the contents of a chart to pan it horizontally.
2859 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).
2861 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double click</b> a panned chart.
2865 <h4>Double Click</h4>
2866 Double Click a chart to reset all the charts to their default auto-refreshing state.
2870 <h4>SHIFT + Drag</h4>
2871 While pressing the shift key, click on the contents of a chart and move the mouse to select an area, to zoom in. The other charts will follow too. Zooming is performed in two phases:
2873 <li>The already loaded chart contents are zoomed (low resolution)</li>
2874 <li>New data are transferred from the netdata server, to refresh the chart with possibly more detail.</li>
2876 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
2880 <h4>SHIFT + Mouse Wheel</h4>
2881 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.
2883 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
2887 <h4>Legend Operations</h4>
2888 Click on the label or value of a dimension, will select / un-select this dimension.
2890 You can press any of the SHIFT or CONTROL keys and then click on legend labels or values, to select / un-select multiple dimensions.
2893 <div role="tabpanel" class="tab-pane" id="help_touch">
2896 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).
2898 All the other visible charts will also show and highlight their values for the same timestamp.
2902 <h4>Drag Chart Contents</h4>
2903 Touch and Drag the contents of a chart to pan it horizontally.
2905 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).
2907 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double tap</b> a panned chart.
2912 Double tap a chart to reset all the charts to their default auto-refreshing state.
2916 <h4>Zoom <small>(does not work on firefox and IE/Edge)</small></h4>
2917 With two fingers, zoom in or out.
2919 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.

When set to <b>All</b>, all dimensions will always be shown.

3045 <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.
