ViewSys

ViewSys is a system resource monitor that displays processor performance statistics and resource consumption for a set polling period. It updates the numbers automatically at the end of each polling period, which allows you to evaluate the effects of changes as those changes are made. ViewSys indicates the current allocation of a given resource and the percentage of that resource used. Thus, possible resource contention problems can be detected before they become serious.

Viewing the resource allocations across processors on a running system allows you to balance the application load more evenly. It can help you decide when to move user processes to processors and disk files that are less busy or when to relocate partitions to disk volumes that are less busy.
