Computer monitoring is a new technique to control costs and improve performance. Critical differences between hardware and software monitors are indicated. Monitoring requires a pragmatic approach since little theory is yet available. Monitoring should be done to one, save money; two, understand the computer system; and three, to indicate future developments. Several specific cases are given showing types of activities monitored, improvements achieved, and concepts used. Fallacies of intuition can be clarified with monitors. Three are mentioned: peak load processing, reasons for delay in terminal response time, and effect of arm contention on dual density disk drives. Future developments should include greater modularity of hardware and software systems, inclusion of specific aids for monitoring (like the Honeywell 6000), and development of measurable performance specifications and units.Problems and costs of monitoring are mentioned.
