Hi Benedict,
as discussed at the #Checkmkconference10 here more information about the problem:
When you use a Bar Gauge it is not possible to remove rows which are "0" (Zero (and or Null)) also not intresting. At the Graph there is a solution in Grafana but not with "Bar Gauge".
The most important one is a switch to remove all rows who are "0"
an additional thing would be a filter to remove rows with special names (we ha an "_all" counter we do not need and who will disturb)
Thanks
Frank
