Detailed Description

Supported statistics:

  • thp_queue_size - current size of the thread pool queue size
  • thp_task_exec_time - the number of microseconds spent by workers to execute tasks
  • thp_worker_exec_time - the number of microseconds spent to by thread pool workers on waiting for tasks and execute tasks
  • sched_task_exec_time - the number of microseconds spent by workers to execute tasks, without callback overhead
  • thp_thread_internal_id - thread internal id, set once after thread starts
