2983 if there is a metric for something, we want it visualised<br/>
2984 and we want this visualisation to be <strong>real-time</strong>, <strong>efficient</strong> and <strong>awesome</strong>
2988 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2989 is a new way to monitor your systems and applications, to get <strong>real-time insights</strong>
2990 of what is really happening and what affects performance.
2991 It is carefully optimised to be a real-time system, without interfering in any way,
2992 to the core function of your systems.
2995 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>
2996 has been designed to monitor <strong>massive amounts of metrics, per server, per second</strong>.
2997 When installed, it might come up with 1k to 3k metrics, but we have been testing it with 100k
2998 metrics, all collected per second, and still the cpu utilisation remained negligible.
3000 We have also tried to give each metric, a meaning, a context.
3001 We have grouped and categorized all metrics into meaningful charts, providing a
3002 better understanding of the underlying technologies and mechanisms.
3005 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> is free,
3006 open-source software. If you decide to use it,
3007 <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>.
3010 Enjoy real-time performance monitoring!

3045 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).
3047 All the other visible charts will also show and highlight their values for the same timestamp.
3051 <h4>Drag Chart Contents</h4>
3052 Drag the contents of a chart to pan it horizontally.
3054 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).
3056 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double click</b> a panned chart.

3065 <h4>SHIFT + Drag</h4>
3066 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:
3068 <li>The already loaded chart contents are zoomed (low resolution)</li>
3069 <li>New data are transferred from the netdata server, to refresh the chart with possibly more detail.</li>
3071 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
3075 <h4>SHIFT + Mouse Wheel</h4>
3076 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.
3078 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
3082 <h4>Legend Operations</h4>
3083 Click on the label or value of a dimension, will select / un-select this dimension.

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

3240 <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.
