- <li>You can host your dashboard anywhere.</li>

<li>You can have charts from many different netdata servers (add <pre>data-host="http://another.netdata.server:19999/"</pre> to each chart).</li>
- <li>You can use different chart libraries on the same page: <b>peity</b>, <b>sparkline</b>, <b>dygraph</b>, <b>google</b>, <b>morris</b></li>
- <li>You can customize each chart to your preferences. For each chart library most of their attributes can be given in <b>data-</b> attributes.</li>
- <li>Each chart can have each own duration - it is controlled with the <b>data-after</b> attribute to give that many seconds of data.</li>
- <li>Depending on the width of the chart and <b>data-after</b> attribute, netdata will automatically refresh the chart when it needs to be updated. For example giving 600 pixels for width for -600 seconds of data, using a chart library that needs 3 pixels per point, will yeld in a chart updated once every 3 seconds.</li>

<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 real-time time series data, from CPU usage, disk activity, SQL queries, API calls, web site visitors, etc.
- </div>
-
<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.
- </div>
-
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/wiki/External-Plugins" target="_blank">external plugins</a>, even <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">shell</a> or <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">node.js</a> plugins. Any computer program, in any language, that can print a few lines of text on its standard output, can be a netdata data collector.
- </div>
-
<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>%),
-
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).
- </div>
-
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/wiki/Performance" target="_blank">a raspberry pi 2 can sustain 300 charts updates per second</a>!).

- 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).
- <br/>

- <h4>SHIFT + Drag</h4>
- 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:

- Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.

- <h4>Legend Operations</h4>
- Click on the label or value of a dimension, will select / un-select this dimension.

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>

+ <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.

+ <div class="p">
+ 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>.

For collecting these numbers, it supports <a href="https://github.com/firehol/netdata/wiki/External-Plugins" target="_blank">external plugins</a>, even <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">shell</a> or <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">node.js</a> plugins.
