A software system is disclosed which facilitates the process of tracing the execution paths of a program, called a client or application. Trace data corresponding to selected system resources that interact with the execution of the application is collected during the tracing operation and stored in an application signature. A computer system user can generate trace options, trace the application, and compare the application signature to a known software configuration. The application signature is compared to a reference signature created by tracing the execution of the application on a system with the known software configuration. In another embodiment, the application signature is compared to a static configuration of a reference computer.
