Abstract
A method and system for enabling the monitoring of software executing on a computer system. The system inserts monitor instrumentation without recompiling the source code of the program. Encapsulation of the target routine does not disrupt the relative addressing of the target routine since an instruction is simply replaced. No instructions are added to the target routine. User specified entry and exit routines are used to collect selected performance and system state data. 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.
