Time-interval based monitor function for dynamic insertion into and removal from a running application

Abstract

A time-interval based monitor tool is provided for monitoring performance of a running application. The tool includes a time-based monitor function which is dynamically insertable into and removable from an address space of a running application to be monitored transparent to the application and without requiring recompilation. The time-based monitor function allows an operator to reset the monitor time interval without requiring extraction of the monitor function. In addition, the time-based monitor function allows access to one or more global variables of the application, and by changing a global variable can effect a change in the application's operation path.
