Abstract: The invention efficiently provides user code information for kernel level tracing approaches. It applies an advanced variation of stack walking called multi-mode stack walking to the entire system level and generates the unified trace where the user code and kernel events are integrated. The invention uses runtime stack information and internal kernel data structures. Therefore, source code for user level code and libraries are not required for inspection. The invention introduces the mechanism to narrow down the monitoring focus to specific application software and improve monitoring performance.

Abstract: A method for request profiling in service systems with kernel events includes collecting kernel events traces from a target system, the kernel event traces being obtainable from individual service machines by instrumenting core kernel functions, analyzing kernel event traces for constructing end-to-end request profiling traces consisting of kernel events belonging to service processes, and categorizing request traces responsive to the analyzing with the constructing including grouping requests based on marking kernel events used in the analyzing.

Abstract: A system for automatically instrumenting and tracing an application program and related software components achieves a correlated tracing of the program execution. It includes tracing of endpoints that are the set of functions in the program execution path that the developers are interested. The tracing endpoints and related events become the total set of functions to be traced in the program (called instrument points). This invention automatically analyzes the program and generates such instrumentation points to enable correlated tracing. The generated set of instrumentation points addresses common questions that developers ask when they use monitoring tools.
