Monitoring overtime of tasks

Abstract

A computer system monitors the execution time of each of a plurality of tasks over a plurality of time periods. The system receives a first input that selects a particular time period from the plurality of time periods, and further monitors the execution time of the plurality of tasks in the selected time period. The system receives a second input that selects a particular task from the particular time period, and monitors the execution time of the particular task in the particular time period.
