1 Getting Started
ViewSys is a system resource monitor. Viewing the resource allocations across
processors on a running system allows you to balance the application load more
evenly. ViewSys can help you decide when to move user processes to less busy
processors and disk files or relocate partitions to less busy disk volumes.
ViewSys indicates the current allocation of a given resource and the percentage used
of that resource, allowing you to detect possible resource contention problems before
they become serious.
The program is nonprivileged. It requires little system overhead and is most useful
when run during application processing.
Starting ViewSys
To start the program, type VIEWSYS at the TACL prompt. ViewSys compiles the
maximum values contained in the ViewSysC file and then puts the terminal in block
mode. Initially, ViewSys displays statistics for all processors that have been configured
on the node. If there are more than eight processors, it alternates between two screens
to display all the processors. You can use the USERCPUS and UPCPUS commands
to limit the number of processors monitored.
