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.

If you are collecting processor performance data from the results output by the sar command in the AIX environment, the displayed values will be for different fields. For details about the values displayed in the fields when collecting processor performance data from the results output by the sar command in the AIX environment, see 2.3.22 Monitoring processor performance based on results output by the sar command in an AIX environment.

Note:

• If the DLPAR function of AIX V6.1 or later, the vPars function of HP-UX 11i, or the DR function of Solaris 10 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:
  Interval (INTERVAL)
  Record Time (RECORD_TIME)
  Record Type (INPUT_RECORD_TYPE)
  Fields that are added only when data is recorded in the Store database
  For details about modifying system resources, see Notes on performance information when modifying system resources in Notes on records.
  

Item	Default value	Modifiable
Collection Interval	60	Yes
Collection Offset#	0	Yes
Log	No	Yes
LOGIF	Blank	Yes

#

A value between 0 and 32,767 seconds can be specified (a value within the range specified for Collection Interval). Use this item to distribute the collection load, because executing data collection all at once results in concentration of the processing workload. Note that the data collection duration to be recorded is the same as the Collection Interval, regardless of the value specified for Collection Offset.

When changing the Collection Offset value, specify a value that takes into account the impact of the collection processing load.
