Re: TimerService Troubleshooting/Metrics
As far as I know, there are no timer service metrics exposed at the moment.
I pull in Stefan into the thread, maybe, he could add more.
In case of RocksDB, you can try enabling RocksDB internal metrics .
Timer service uses RocksDB state backend to queue timers and has a dedicated column in RocksDB.
The metrics of this column might help, like 'state.backend.rocksdb.metrics.estimate-num-keys’.
