ABSTRACT:
A system and method for monitoring software locks is presented. Metric data collection is invoked only when thin lock contention arises in a computer system's application layer. Instrumentation in a computer system's middleware layer tracks time-based metric information such as a waiting time for an application to acquire a lock. Instrumentation tracks garbage collection events and removes garbage collection time durations from time-based metric data as to not distort time-based metric data. Instrumentation also tracks quantity-based events such as the number of applications that request a particular lock. An instrumentation user may retrieve metric data for computer system performance analysis.
