Abstract
A performance monitoring device has an interrupt detection unit that detects generation of an interrupt process to be executed by a processor in accordance with TLB entry invalidation executed in an operating system. A counter value acquisition unit acquires a counter value of a predetermined event counted by the processor when the interrupt process is detected by the interrupt detection unit. A process information acquisition unit acquires identification information for identifying a process executed on the processor from the operating system immediately before the interrupt process is detected by the interrupt detection unit. An associating unit associates the counter value acquired by the counter value acquisition unit during the interrupt process with the identification information acquired by the process information acquisition unit immediately before the interrupt process.
