摘要：
The present invention is directed to a system and method of measuring performance data utilizing state transitions within a computer system. A number of system states are defined, and the transitions from one state to another are tracked. At each state transition, performance properties related to the computer system may be checked or calculated, and performance data added to a table or tables. The present invention allows performance data to be measured in a way that is highly precise and has minimal effects on the system performance being measured. The act of measuring performance data utilizing state transitions does not create a misleading measure of performance nor does it adversely impact system performance. Furthermore, the present invention requires minimal changes to the operating system and no changes to application code.
