The service list status views of Check_MK can now be sorted by the column "Perf-O-Meter".

The sorting of the perfometers is sorted by these values:

  1. First sort by the optional perfometer group or perfometer ID
  2. Second sort by the sort value of each perfometer

The Perfometer group / perfometer ID

Each perfometer declaration can have an optional element sort_group. This element holds a string that can be used to group different perfometers (that visualize comparable values) together.

In case no sort_group is defined, the internal ID of the perfometer definition is used. This means that all perfometers which are rendered by the same logical function are sorted together in a perfometer group.

The sort value

The sort value of a perfometer is calculated in different ways for each perfometer type based on the current metrics of this service.

  • Logarithmic: The single logarithmic value displayed by this perfometer is used
  • Linear: The first segment of the displayed values is used
  • Stacked: The sort value of the first stacked perfometer is used
  • Dual: The maximum of both displayed value is used for sorting

The sorting only works for perfometers that are implemented as metric plugin (in plugins/metrics/). The legacy perfometers that are implemented as perfometer plugins can not be sorted.

Dear check developers: All perfometers that visualize equal types of values have to be sorted together in a sort group. For example all checks that monitor fileystems should have equal perfometers that can be compared to each other and should therefor be sortable by their disk usage.
