2750 if there is a metric for something, we want it visualised<br/>
2751 and we want this visualisation to be <strong>real-time</strong>, <strong>efficient</strong> and <strong>awesome</strong>
2755 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2756 is a new way to monitor your systems and applications, to get <strong>real-time insights</strong>
2757 of what is really happening and what affects performance.
2758 It is carefully optimised to be a real-time system, without interfering in any way,
2759 to the core function of your systems.
2762 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2763 has been designed to monitor <strong>massive amounts of metrics, per server, per second</strong>.
2764 When installed, it might come up with 1k to 3k metrics, but we have been testing it with 100k
2765 metrics, all collected per second, and still the cpu utilisation remained negligible.
2767 We have also tried to give each metric, a meaning, a context.
2768 We have grouped and categorized all metrics into meaningful charts, providing a
2769 better understanding of the underlying technologies and mechanisms.
2772 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> is free,
2773 open-source software. If you decide to use it,
2774 <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>.
2777 Enjoy real-time performance monitoring!

2811 <h4>Mouse Over / Hover</h4>
2812 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).
2814 All the other visible charts will also show and highlight their values for the same timestamp.
2818 <h4>Drag Chart Contents</h4>
2819 Drag the contents of a chart to pan it horizontally.
2821 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).
2823 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double click</b> a panned chart.
2827 <h4>Double Click</h4>
2828 Double Click a chart to reset all the charts to their default auto-refreshing state.
2832 <h4>SHIFT + Drag</h4>
2833 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:
2835 <li>The already loaded chart contents are zoomed (low resolution)</li>
2836 <li>New data are transferred from the netdata server, to refresh the chart with possibly more detail.</li>
2838 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
2842 <h4>SHIFT + Mouse Wheel</h4>
2843 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.
2845 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
2849 <h4>Legend Operations</h4>
2850 Click on the label or value of a dimension, will select / un-select this dimension.
2852 You can press any of the SHIFT or CONTROL keys and then click on legend labels or values, to select / un-select multiple dimensions.
2855 <div role="tabpanel" class="tab-pane" id="help_touch">
2858 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).

2864 <h4>Drag Chart Contents</h4>
2865 Touch and Drag the contents of a chart to pan it horizontally.
2867 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).
2869 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double tap</b> a panned chart.

When set to <b>All</b>, all dimensions will always be shown. Set it to <b>Non Zero</b> to lower the data transferred between netdata and your browser, lower the CPU requirements of your browser (fewer lines to draw) and increase the focus on the legends (fewer entries at the legends).</small>

When set to <b>Hide</b>, the not-visible charts will be just hidden, to simplify the DOM and speed up your browser. Set it to <b>Destroy</b>, to lower the memory requirements of your browser.

3001 <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.

3007 <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>
