Abstract: PROBLEM TO BE SOLVED: To provide an improved method and device for monitoring the performance of a data processing system. SOLUTION: A cyclically generated event such as timer interruption or the like is detected and a stack related to a program is identified in response to the detection of such an event. The stack is investigated and respective routines (and specified calling point or offset) executed at present relating to the program are identified. The respective routines (and offset) are indicated as nodes inside a tree structure.
