About This Manual
ViewSys gives system managers and system operators the ability to view system
resources on HP NonStop systems. It also provides data to those responsible for load
balancing and overall system performance.
ViewSys returns system resource information interactively, reporting data similar to that
provided by PEEK, another HP NonStop resource reporting utility, and Measure, an HP
NonStop performance analysis tool. PEEK displays resource use from a specific
timestamp to the present. ViewSys provides the average resource use for each polling
period.
Measure provides detailed resource use for each interval, but the results are generally
interpreted offline after the measurement is complete. ViewSys allows the viewing of
system resources in an online environment, so you can view the effects of process
relocations or the altering of controller paths as the changes are made. ViewSys must
be run from an HP block mode terminal or from any HP NonStop terminal emulator.
If you are familiar with either Measure or PEEK, you can translate that knowledge to
this utility and need only become familiar with the commands and function keys to
control the utility. If you are unfamiliar with the resources being measured, first read the
Measure User's Guide.
