2981 if there is a metric for something, we want it visualised<br/>
2982 and we want this visualisation to be <strong>real-time</strong>, <strong>efficient</strong> and <strong>awesome</strong>
2986 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2987 is a new way to monitor your systems and applications, to get <strong>real-time insights</strong>
2988 of what is really happening and what affects performance.
2989 It is carefully optimised to be a real-time system, without interfering in any way,
2990 to the core function of your systems.
2993 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2994 has been designed to monitor <strong>massive amounts of metrics, per server, per second</strong>.
2995 When installed, it might come up with 1k to 3k metrics, but we have been testing it with 100k
2996 metrics, all collected per second, and still the cpu utilisation remained negligible.
2998 We have also tried to give each metric, a meaning, a context.
2999 We have grouped and categorized all metrics into meaningful charts, providing a
3000 better understanding of the underlying technologies and mechanisms.
3003 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> is free,
3004 open-source software. If you decide to use it,
3005 <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>.
3008 Enjoy real-time performance monitoring!

3042 <h4>Mouse Over / Hover</h4>
3043 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).
3045 All the other visible charts will also show and highlight their values for the same timestamp.
3049 <h4>Drag Chart Contents</h4>
3050 Drag the contents of a chart to pan it horizontally.
3052 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).
3054 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double click</b> a panned chart.

3063 <h4>SHIFT + Drag</h4>
3064 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:
3066 <li>The already loaded chart contents are zoomed (low resolution)</li>
3067 <li>New data are transferred from the netdata server, to refresh the chart with possibly more detail.</li>
3069 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
3073 <h4>SHIFT + Mouse Wheel</h4>
3074 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.
3076 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
3080 <h4>Legend Operations</h4>

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

3238 <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.
