Busiest Processes (by CPU) (PBSYCPU)
This report uses the GLOBINFO, VSIOTOT, and DOPENSUM entities.
Parameters used are:
•
LID—specifies the Measure Load ID
•
EXCLUDE—specifies a value under which to exclude the number of requests per
second
•
SECTION—specifies the report section number
The report is sorted by volume name and descending total driver calls.
Busiest Processes (by CPU) (PBSYCPU)
This 132-column report shows the busiest processes in each CPU. The report
includes:
•
Average time messages spent on $RECEIVE queue
•
Average memory pages used
•
Total CPU busy time
•
CPU utilization (as percentage of measurement window)
•
Priority
•
Ratio of total ready time to CPU busy time
•
Messages received per second
•
Messages sent per second
•
Ratio of messages sent to messages received
•
Average CPU milliseconds consumed per message received
•
Average CPU milliseconds consumed per message sent
