Specifically, I am referring to those companies which need to manage data and applications located on more than one server. In a future grafana releases, this plugin will be incorporated into the main influx plugin and allow a single datasource to support flux queries or influxql (SQL style) queries. On dashboard load works great for me, as I want it to refresh everytime I open the dashboard. With variables you can replace constants in your query in Grafana with – well you guessed it – a variable. SELECT mean(“value”) FROM “check_load” WHERE “hostname” =~ /^$hostname$/ AND “metric” = ‘load15’ AND $timeFilter GROUP BY "hostname" So my first idea was to have the query divided by 1000000 to transform bytes to megabytes.

The plugin includes a custom query editor and supports annotations and query templates. Here's the most promising approach I have tried: However, the problem is that InfluxDB wants its contents in double quotes and Grafana wraps the contents of FROM field with double quotes as well, so the resulting query fails to executed: "FritzBox" WHERE $timeFilter GROUP BY time(10s) fill(null). 1489457127000000000 host002 used_space DISK 20 SELECT (mean("TotalBytesReceived64") - MY_SUB_QUERY) / 1000000 FROM "autogen". Now we have both Influx and Grafana running, we can stitch them together.
