Abstract: Systems and methods for analyzing performance of a processing system are based on performance counters provided in trace points located at selected nodes of the processing system. A first transaction to be monitored is identified as a transaction to be monitored at a first trace point if the transaction is detected, by a performance counter, more than a threshold number of times at the first trace point. A first trace tag identifier is associated with the first transaction at the first trace point. The first transaction is identified at one or more other trace points based on the first trace tag identifier. Based on time stamps at which the first transaction is identified at the trace points, information such as trace information, latency, locality of a consuming device of the first transaction, etc. is obtained from the various trace points.
