Concepts for logging and retrieving diagnostic information relating to a computer system that implements a runtime stack when executing a program are presented. One example comprises, determining a depth value, the depth value being configured to identify a level of diagnostic tracing for the runtime stack. For each stack frame of the runtime stack: the depth value is compared with a counter value associated with the stack frame, and data is then retrieved from the stack frame based on the comparison result.

Obtaining diagnostic information

A mechanism is provided for identifying an inter-relationship between a first process and the second process of a computer system. A correlation is detected between the first process and the second process based on a timing of the first process and the second process accessing a system resource of the computer system. An inter-relationship is then identified between the first process and the second process based on the detected correlation between the first process and the second process.
