Abstract: A system and method for tracing individual transactions on method call granularity is disclosed. The system uses instrumentation based transaction tracing mechanisms to enhance thread call stack sampling mechanisms by a) only sampling threads executing monitored transactions while execution is ongoing b) tagging sampled call stacks with a transaction id for correlation of sampled call stacks with instrumentation bases tracing data. The combination of instrumentation based tracing with thread call stack sampling reduces sampling generated overhead by only sampling relevant thread, and reduces instrumentation generated overhead because it allows reducing instrumentation.
