CPU - Per Processor Detail (PI_CPUP)

Function

The CPU - Per Processor Detail (PI_CPUP) record stores the performance data per unit time on the processor usage. Every time performance data is collected, a record is created for each processor. This is a multi-instance record.

Note:
  • If the DLPAR function of AIX 5L V5.3 or later, the vPars function of HP-UX 11i, or the DR function of Solaris 9 or later is used to modify a system resource while a PFM - Agent for Platform service is running, some types of performance data cannot be correctly collected. The table below shows the types of system resources that are affected and the actions that you can take to correctly display reports after the modification:
    System resource type Report type Actions to be taken after modification
    CPU Real-time Display the report again.
    Historical Specify the display period such that it does not include the date and time when the system resources were modified.
    Fields other than those listed below are affected by a system resource modification:
    [Figure] Interval (INTERVAL)
    [Figure] Record Time (RECORD_TIME)
    [Figure] Record Type (INPUT_RECORD_TYPE)
    [Figure] Fields that are added only when data is recorded in the Store database
    For details about the notes on modifying system resources, see Notes on performance information when modifying system resources under Notes on records in this chapter.
