Westwood, Massachusetts-based Cullinet Software Inc has a new windowing facility for resource management in Release 10.1 of Performance Monitor, its on-line program analysis system for users of the IDMS/R database manager. It comprises three tools, Application Monitor, System Interval Monitor and Realtime Monitor. The Realtime Monitor provides the system programmer with statistics on resources the system is currently using, automatically refreshing the screen display with new data. The System Interval Monitor displays detailed wait statistics for a defined time interval. The new multiple windowing display enables the user to view several resources concurrently, helpful in using the Realtime and System Interval Monitors, since it allows a comparison of the use of various resources in the system simultaneously. A multi-directional scrolling feature enables users to take advantage of their terminals’ full data presentation potential by offering the capability to view information beyond the standard screen.
