Abstract: An application for use in a data processing system contains instrumentation code with calls to a probe module (class) containing first and second sub-programs. If no profiling or tracing actions are required then the application is deployed with a first version of the module wherein the first and second sub-programs have null code. If profiling is desired a second version if the probe module having appropriate code for profiling and monitoring the performance of the data processing system is deployed. The probe class can be used to obtain timing information and the timing information can be output to a trace file. The application can be a Java servlet to obtain information about time spent by Java code processing HTTP transactions in a web server.
