Patent ID: 7472039

Claim:
A computer-readable storage medium encoded with instructions that, when executed on a computer, perform a method comprising: sampling addresses being accessed by a central processing unit (CPU) at prescribed sampling intervals, and recording the sampled addresses and acquisition times thereof in an address record table in an order that the addresses are sampled; searching a process-address table for a name of a process corresponding to each sampled address recorded in the address record table, and adding the name of the process to a corresponding entry of the address record table, the process-address table storing names of processes to be executed by the CPU and addresses to be specified during execution of the processes; counting, in response to an analysis request specifying an analysis time period, occurrences of each process name in the address record table for each analysis time period specified, and summarizing executed processes for each analysis time period, based on a number of occurrences of each process name; and displaying results of said summarizing on a monitor screen.
