I use telegraf for data collection and monitor a few processes with the procstat module.
At the moment i query the results manually in grafana from influxdb.
SELECT mean("cpu_usage") AS "telegraf" FROM "procstat" WHERE "exe" = 'telegraf' AND "host" = 'grafana' AND $timeFilter GROUP BY time($interval) fill(null)
I tried using
… WHERE "exe" = '*' … in grafana but that does not return results.
Where is the error in the query?
Thank you very much for your help.
