Method Detail

getThreads

ThreadData[] getThreads()

Returns all the threads that are currently in the monitored application. NOTE If running in "event only" mode, this data will always return an empty array. This is because "event only" does not store any data to inquire on. Instead, you need to use the api calls to register listeners and get notification of when events occur

Returns:

an array of ThreadData objects containing the current threads

getThreadCounts

CountData[] getThreadCounts()

Returns the number of threads in the application over time. NOTE If running in "event only" mode, this data will always return an empty array. This is because "event only" does not store any data to inquire on. Instead, you need to use the api calls to register listeners and get notification of when events occur

Returns:

an array of CountData objects. Each object contains a time and the number of threads that were in the monitored application at that time.

deadlockDetected

boolean deadlockDetected()

Returns whether a deadlock scenario has been detected in the monitored threads.

Returns:

true if a deadlock scenario has been detected, otherwise false.

getLatestThreads

ThreadData[] getLatestThreads()

Returns the latest set of threads in the monitored application. NOTE If running in "event only" mode, this data will always return an empty array. This is because "event only" does not store any data to inquire on. Instead, you need to use the api calls to register listeners and get notification of when events occur

Returns:

an array of ThreadData objects containing the latest threads

getAllThreads

java.util.HashMap<java.lang.Long,ThreadData[]> getAllThreads()

Returns all the threads in the monitored application over time.

Returns:

a HashMap containing the time of the thread snapshot and an array of ThreadData objects

addThreadListener

void addThreadListener(ThreadEventListener listener)

Add a listener for notification of when a thread event occurs

Parameters:

implementation - of the ThreadEventListener class

removeThreadListener

void removeThreadListener(ThreadEventListener listener)

Remove one of registered listeners.

Parameters:

implementation - of the ThreadEventListener class
