<h5>Alias patterns</h5>
|
|
<ul>
|
|
<li>$m = replaced with measurement name</li>
|
|
<li>$measurement = replaced with measurement name</li>
|
|
<li>$1 - $9 = replaced with part of measurement name (if you separate your measurement name with dots)</li>
|
|
<li>$col = replaced with column name</li>
|
|
<li>$tag_hostname = replaced with the value of the hostname tag</li>
|
|
<li>You can also use [[tag_hostname]] pattern replacement syntax</li>
|

<h5>Stacking and fill</h5>
|
|
<ul>
|
|
<li>When stacking is enabled it important that points align</li>
|
|
<li>If there are missing points for one series it can cause gaps or missing bars</li>
|
|
<li>You must use fill(0), and select a group by time low limit</li>
|
|
<li>Use the group by time option below your queries and specify for example >10s if your metrics are written every 10 seconds</li>
|
|
<li>This will insert zeros for series that are missing measurements and will make stacking work properly</li>
|
|
</ul>
|
|

<div class="grafana-info-box span6" ng-if="ctrl.panelCtrl.editorHelpIndex === 3">
|
|
<h5>Group by time</h5>
|
|
<ul>
|
|
<li>Group by time is important, otherwise the query could return many thousands of datapoints that will slow down Grafana</li>
|
|
<li>Leave the group by time field empty for each query and it will be calculated based on time range and pixel width of the graph</li>
|
|
<li>If you use fill(0) or fill(null) set a low limit for the auto group by time interval</li>
|
|
<li>The low limit can only be set in the group by time option below your queries</li>
|
|
<li>You set a low limit by adding a greater sign before the interval</li>
|
|
<li>Example: >60s if you write metrics to InfluxDB every 60 seconds</li>
|
|
</ul>
