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:
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.
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.
