Method Detail

getInflatedJavaMonitors

MonitorData[] getInflatedJavaMonitors()

Gets an array of MonitorData objects representing locks taken by the application that is being monitored.

Returns:

an array of MonitorData objects.

getInflatedSystemMonitors

MonitorData[] getInflatedSystemMonitors()

Gets an array of MonitorData objects representing locks taken by the Java runtime environment.

Returns:

an array of MonitorData objects.

startNotifying

void startNotifying(long delay)

Starts a thread which checks for updates and sends Notifications if any updates have occurred. To handle these notifications, a NotificationListener needs to be added to the class the thread is being started from.

Parameters:

delay - The number of milliseconds between each update. The default is 2000 milliseconds and anything below this will not be accepted.
