Detailed Description

Supported statistics:

  • active_job_cnt - the number of currently executed jobs by thread pool workers (equal to active workers)
  • active_trx_cnt - the number of currently applied transactions (started transactions, active until "commit", regardless possible wait on commit order)
  • committed_cnt - transactions committted count
  • trx_exec_time - transactions execution time (all transactions executed for a particular instance id / channel id)
  • worker_session - session ids currently utilized by workers
  • session_worker - workers that currently work on a given session
  • trx_provided_cnt - provided transaction count (e.g. read)
  • trx_scheduled_cnt - scheduled transaction count
  • ap_queue_size - asynchronous provider queue size
  • applied_events_cnt - the overall, and ever-increasing, number of applied events
