Methods

Modifier and Type	Method and Description

Method Detail

started

void started(ThreadMonitor.ThreadExecutionState state)

Callback method to notify a thread has started execution.

Note: ThreadExecutionState's end time is updated by the executing thread, so by the moment the state is processed the thread might have finished execution.

Parameters:

state - thread execution state

finished

void finished(ThreadMonitor.ThreadExecutionState state)

Callback method to notify a thread has finished execution. This method could be used to track threads that take too long to execute.

Parameters:

state - thread execution state

executing

void executing(Collection<ThreadMonitor.ThreadExecutionState> states)

Callback method to notify a snapshot of the active threads in execution. This method could be used to track threads spending too long in execution state (Potentially in deadlock).

Note: ThreadExecutionState's end time is updated by the executing thread, so by the moment the state is processed the thread might have finished execution.

Parameters:

states - threads execution states

overlapped

void overlapped(ThreadMonitor.ThreadExecutionState state,
              javax.measure.Measurable<javax.measure.quantity.Duration> period)

Callback method to notify when a Runnable is submitted to be executed at a fixed rate but it took more time to execute than its period.

Parameters:

state - thread execution state

period - period the Runnable was scheduled with.

failed

void failed(ThreadMonitor.ThreadExecutionState state,
          Exception failure)

Callback method to notify a thread has failed and the exception was not caught.

Parameters:

state - thread execution state

failure - failure
