Abstract

The Graphic Display Monitoring System (GDM) is an experimental monitoring facility for Multics, a general purpose time-sharing system implemented at Project MAC cooperatively with General Electric and the Bell Telephone Laboratories. GDM allows design, systems programming, and operating staff to graphically view the dynamically changing properties of the timesharing system. It was designed and implemented by the author to provide a medium for experimentation with the real-time observation of time-sharing system behavior. GDM has proven to be very useful both as a measuring instrument and a debugging tool and as such finds very general use.
