C, the partition running time to be monitored;
In partition operating system runs, when process or empty interruption switch, check whether that subregion occurs to be switched, and switches if there occurs subregion, then calculate this working time subregion simultaneously; Specific as follows:
Update time, step 3 by the last subregion in subregion integrating instrument) described in subregion outer working time and current time calculate, formula is:
Subregion this working time=(current time)-(update time of last subregion)-(subregion outer working time)
Subregion is increased in subregion accumulator this working time;
6) step 3 is repeated) to step 5), realize the event-monitoring interrupted empty in process in subregions all in operating system, subregion and subregion.
The invention has the advantages that:
