Special Considerations

Your PPU system/partition’s processor utilization information is 
available from the HP PPU web portal. See “PPU Web Portal” on page 36 
for details of the PPU web portal.

If you are interested in verifying PPU utilization information against the 
PPU web portal information, you can use the 

sar

 command to compare 

processor utilization numbers. The 

sar

 command is a HP-UX system 

activity reporter that samples and accumulates processor utilization. See 
the manpage sar  (1M ) for details on the 

sar

 command.

An overview of the processor utilization verification process is:

•

Create processor utilization numbers for your PPU system/partition 
with the 

sar

 command

•

Go to the PPU web portal and capture processor utilization numbers 
for the same PPU system/partition and duration of time

•

Verify  the 

sar

 utilization numbers against the PPU web portal 

utilization numbers

To perform the utilization verification process, perform the following 
steps:

Because the PPU web-portal’s utilization reports contain 30 minutes of 
information, beginning on the hour or on the half-hour, it is 
recommended to time the execution of 

 (below) immediately upon 

the start of a hour, or half past the hour. Another option is to create a 
shell script that contains the command in 

 and schedule a 

cron

 job 

so it starts exactly on the hour or half hour.

Step 1. In a terminal window on the PPU system, execute the following 

command:

Where “300” represents the (averaged) interval duration of the 
utilization sample, in seconds, and “12” represents the number of
