System Summary Overview (PI)
- Organization of this page
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 2.3.23 Monitoring processor performance based on results output by the sar command in an AIX environment.
- Notes:
-
-
If you are collecting data in a Solaris 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 you are collecting data in a Solaris non-global zone environment, the following fields cannot be collected:
Cache Mem %, Cache Mem Mbytes, Effective Free Mem %, Effective Free Mem Mbytes
Also, the correct value is not collected in the non-global zone environment for the following fields:
Effective Used Mem %, Effective Used Mem Mbytes
(For Effective Used Mem %, 100.0000 is collected, and for Effective Used Mem Mbytes, the same value as Total Physical Mem Mbytes is collected.)
-
If you collect in a non-global zone environment of Solaris, the value of the Boot Time field might not be displayed correctly.
Display example: 1970 01 01 06:00:00

If the DLPAR function of AIX, the vPars function of HP-UX, the DR function of Solaris, or the CPU hotplug of Linux 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.

In AIX, the following fields of PI record treat assigned file cache as "used physical memory".
- Alloc Mem %
- Alloc Mem Mbytes
- Free Mem %
- Free Mem Mbytes
-
If you want to monitor the amount of memory actually available, we recommend that you monitor the Effective Free Mem Mbytes field, not the Free Mem Mbytes field. (Excluding the non-global zone environment of Solaris)
Similarly, for the Free Mem %, Alloc Mem Mbytes, and Alloc Mem % fields, we recommend that you monitor the Effective Free Mem %, Effective Used Mem Mbytes, and Effective Used Mem % fields, which all begin with Effective, respectively.
For details about the difference between the fields, see 3.1.2(2)(e) Checking the amount of memory that the system can actually use.

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.
