Strategy: Don't use already-aggregated values

Be aware of already-aggregated values returned by systems and applications. Apache for example returns a value "137.5 kB/request". Sounds good, but this is not a value at the current time of measurement. Instead, it is the average of all requests during the lifetime of the Apache worker process. If you use this in some sort of Grafana panel, you just get a boring line which converges towards a constant value very fast. Not useful at all.

A monitoring plugin has to calculate such values always on its own. If this is not possible because of missing data, discard them.

Task:

• Search all Grafana panels for such values.
• Re-calculate those values on your own, or discard them.
