System Summary Overview (PI)

Function

The System Summary Overview (PI) record stores the performance data per unit time on the entire system.

If you are collecting processor performance data from the results output by the sar command in the AIX environment, the displayed numeric 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.

Notes:
  • If you are collecting data in a Solaris 10 non-global zone environment or an AIX System WPAR environment, the following fields cannot be collected:
    NFS Server Lookup Ops, NFS Server Ops/sec, NFS Server Read Ops, NFS Server Read Ops/sec, NFS Server Total Bad Ops, NFS Server Total Ops, NFS Server Write Ops, NFS Server Write Ops/sec
  • If the DLPAR function of AIX V6.1, 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.

Collection Offset#0Yes
LogNoYes
LOGIFBlankYes
#
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.
