2 ViewSys Overview
ViewSys runs on all HP NonStop servers as a nonprivileged process. It displays
system resource use in block mode and bar graph form and allows you to select from a
number of display screens.
ViewSys allows you to:
•
Monitor all processors within a system
•
Monitor a selected set of processors within a system
Once ViewSys is running, you can select a screen to:
•
View resource use within a single processor
•
View resource use within all processors being monitored (See Figure 2-1.)
•
View the use of a single resource throughout all the processors being monitored
Figure 2-1 shows resource use for CPU00.
The following metrics are reported for each processor being monitored. You can tailor
each metric's maximum value for controlling the graph size to the users environment.
For an explanation of altering the maximum values, see Appendix D, ViewSys
Definition Language (VDL). Section 5, Interpreting ViewSys, shows a sample screen
for each of the entities reported:
•
Processor busy
•
Processor queue length
•
Page fault rate
•
Memory queue length
