...
Add the following metrics via a sensor:1) kafka.coordinator.group
- kafka.server:type=
...
- group-coordinator-metrics,name=
...
- group-load-time-max
Type: SampledStat.Max
Value: 0 or greater over time; maximum time, in milliseconds, it took to load offsets and group metadata from
...
the __consumer_offsets
...
partitions loaded in the last
...
30 seconds.
...
- kafk.aserver:type=group-coordinator-metrics,name=group-load-time-avg
Type: SampledStat.Avg
Value: 0 or greater over time; average time, in milliseconds, it took to load offsets and group metadata from the __consumer_offsets partitions loaded in the last 30 seconds.
Note: this average may look very low at times when a majority of the partitions are unused causing some load times to be 0 seconds.
- kafka.server:type=transaction-coordinator-metrics,name=transaction-load-time-max
Type: SampledStat.Max
Value: 0 or greater over time; maximum time, in milliseconds, it took to load offsets and transaction state from
...
the __
...
transaction_state partitions loaded in the last 30 seconds.
- kafka.server:type=transaction-coordinator-metrics,name=transaction-load-time-avg
Type: SampledStat.Avg
Value: 0 or greater over time; average time, in milliseconds, it took to load offsets and transaction state from the __transaction_state partitions loaded in the last 30 seconds.
Note: this average may look very low at times when a majority of the partitions are unused causing some load times to be 0 seconds.
Proposed Changes
For each of the group metadata manager and transaction state manager, add a sensor that indicates the max and avg number of milliseconds it took to load the each partition. This max is and average are computed from a running window based on the partitions that were loaded finished loading in the last 3 hours. Lengthening or shortening the 3 hour time window is up for discussion (default is 30sec)30 seconds.
