Field |
Description |
|---|---|
thread_creations |
Total number of times that threads are successfully created since the thread group is initialized |
thread_creations_due_to_stall |
Number of times that threads are successfully created by check_stall since the thread group is initialized |
wakes |
Total number of thread wakeups since the thread group is initialized |
wakes_due_to_stall |
Total number of thread wakeups by the timer thread since the thread group is initialized |
throttles |
Total number of times that threads are successfully created due to timeout detection since the thread group is initialized. The value increases by 1 each time when the timer thread identifies that the interval between the last thread creation time and the current creation exceeds the value of throttling_interval by calling check_stall. |
stalls |
Number of suspensions detected by the timer thread by calling check_stall since the thread group is initialized |
dequeues_by_listener dequeues_by_worker |
Number of times that tasks are pulled from the queue since the thread group is initialized.
|
