ABSTRACT:
A method and system for enabling the monitoring of a target software routine in a stripped object executable on a computer system. The system enables monitor instrumentation of the target routine without access to or recompiling the source code of the object and without access to information required to link with the stripped object. A single demultiplexor entry for each target routine provides access to common instrumentation code and to user specified entry and exit routines for the particular target routine. Common instrumentation code is not replicated when used to monitor a number of software programs. User specified entry and exit routines are used to collect selected performance and system state data. Common instrumentation code is provided to link the target routines to the user specified entry and exit routines. The standard link interface allows the entry and exit routines to be written in high level languages.
