A Computer System Performance Measurement Program.
Abstract
Computer performance information is usually collected by three types of measurement tools: (1) accounting logs which are operating system routines that record the quantities of system resources used by each job, (2) hardware monitors which operate independently of the monitored host system and interface to the host system to record selected events or performance data, and (3) software monitors which are memory - resident programs that search operating system tables for meaningful data. The data from each tool can be implicitly or explicitly synchronized to the computer clock. A software program, written in FORTRAN 4, is used to consolidate the performance data from these tools and provide output summaries of user specified parameters. The evaluation time periods of the performance data are defined by the program user. The software program is organized into modules so that it can be used in different computer systems if a small portion of the program is recoded.
