Grafana supports different storage backends which provides a variety of ways to query and visualize the data. The mapSeries and reduceSeries take this list and for each server applies the asPercent reduce function to the two values. It should already be implemented in #10050. See joining series in the InfluxDB docs on how to do this in your The divideSeries function can be used in a Graph panel too, as long as the divisor is a single time series (for example, it will work for the sum of all servers but not when grouped by server). I still loathe MRTG graphs, but configuring InfluxSNMP was a bit of a pain. Trusted and loved by the community. If the query letter is white, then the results are displayed. Usage InfluxDB.
