Alias patterns
+
+ - $m = replaced with measurement name
+ - $measurement = replaced with measurement name
+ - $tag_hostname = replaced with the value of the hostname tag
+ - You can also use [[tag_hostname]] pattern replacement syntax
+
+
+
+
+
Stacking and fill
+
+ - When stacking is enabled it important that points align
+ - If there are missing points for one series it can cause gaps or missing bars
+ - You must use fill(0), and select a group by time low limit
+ - Use the group by time option below your queries and specify for example >10s if your metrics are written every 10 seconds
+ - This will insert zeros for series that are missing measurements and will make stacking work properly
+
+
+
+
+
Group by time
+
+ - Group by time is important, otherwise the query could return many thousands of datapoints that will slow down Grafana
+ - 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
+ - If you use fill(0) or fill(null) set a low limit for the auto group by time interval
+ - The low limit can only be set in the group by time option below your queries
+ - You set a low limit by adding a greater sign before the interval
+ - Example: >60s if you write metrics to ElasticDB every 60 seconds
