Abstract

A major objective for all interactive systems is to provide adequate response time performance for terminal users. The best way to find the causes of inadequate response is to examine the behaviour of the components of response time plotted against workload. (Examples of components are : time running or waiting for the CPU, and time spent waiting for IO transfers). This report describes the development of ASHMON, a monitoring package designed to produce such plots for Prime 50 series computers. In addition to software performance monitors, the package includes data interpretation programs which produce performance summaries and plots, a program which combines data from a number of monitoring sessions, and a program to configure the package on any Prime 50 series machine (apart from the P850). The report also includes discussion of experiments done to validate measurements obtained by the monitors.
