Call stack sampling for a multi-processor system
A computer implemented method for sampling call stack information. Responsive to identifying a set of interrupts, a determination is made as to whether all processors in a plurality of processors have generated the set of interrupts.

| Zusammenfassung: | A computer implemented method for sampling call stack information. Responsive to identifying a set of interrupts, a determination is made as to whether all processors in a plurality of processors have generated the set of interrupts. A number of addresses are identified for a set of interrupted threads identified by the set of interrupts response to a determination that all of the processors have generated the set of interrupts. A determination is made as to whether the identified address falls within a set of address ranges. Responsive to a determination that the identified address falls within the set of address ranges, a sampler thread is notified to obtain call stack information. |
