Elapsed time in seconds after the first event recorded in trace (if available)
Process identifier
Name of the process using the lock
Stack of called methods (if available)
The number of times the lock was acquired in the analysis interval
The percentage of attempts that failed to acquire the lock
The number of unsuccessful attempts to acquire the lock
The number of times a thread is forced into a suspended wait state while
waiting for the lock to come available
The number of trylock calls that returned busy

The total number of processor seconds the lock is
held by a running thread.
The total number of elapsed seconds the lock is
held, whether the thread was running
or suspended.
The percentage of the cumulative processor time
the lock was held by a running thread.
The percentage of the elapsed real time the lock is
held by any thread, either running or suspended.
The percentage of the cumulative processor time
that running threads spend spinning while it tries to
acquire this lock.
The percentage of elapsed real time that any
thread was waiting to acquire this lock. If two or
more threads are waiting simultaneously, this wait
time is only charged one time. To learn how many
threads are waiting simultaneously, look at the
WaitQ Depth statistics.
The minimum, maximum, and average number of
threads that are spinning on the lock, whether
running or suspended, across the analysis interval
The minimum, maximum, and average number of
threads that are waiting on the lock, across the
analysis interval
The minimum, maximum, and average recursion
depth to which each thread held the lock
