Detailed performance analysis by flow aware marker mechanism

摘要

According to aspects of the disclosure, a method is provided comprising: executing a set of threads in a storage system, the set of threads including at least a first thread; executing a plurality of performance counters of the storage system, the plurality of performance counters including at least: (i) a first performance counter that is executed when an operating state of the first thread is changed in response to the first thread accessing a synchronization object, and (ii) a second performance counter that is executed when a marker inserted in the first thread is executed; generating one or more performance data containers associated the first thread based on performance data associated with the first thread; and generating a directed graph based on the performance data containers.
