System Summary (PI)
- Organization of this page
Function
The System Summary (PI) record stores performance data, taken at a specific interval, about the processors and memory in the entire system of the monitored host.
Note
-
If the connection to the monitored host fails, the information cannot be collected.
-
If the OS of both the PFM - RM host and the monitored host is 64-bit Windows, you can collect a maximum of 32 pieces of CPU information.
-
There is no upper limit to the number of instances you can create. The maximum number of monitoring targets you can create per instance is 50.
-
If the OS of both the monitored hosts is HP-UX, AIX, or Linux, the memory size allocated as the file cache is treated as the size of used physical memory area in the following fields:
-
Free Mem % (FREE_MEM_PERCENT)
-
Free Mem Mbytes (FREE_MEM_MBYTES)
-
Used Mem % (USED_MEM_PERCENT)
-
Used Mem Mbytes (USED_MEM_MBYTES)
-
-
If the OS of the monitored host is AIX and a user other than the root user is collecting information, 0 is displayed in the following fields if that user does not belong to either the adm group or system group:
-
CPU % (CPU_PERCENT)
-
Idle % (IDLE_PERCENT)
-
System % (SYSTEM_PERCENT)
-
User % (USER_PERCENT)
-

-
Free Swap Mbytes (FREE_SWAP_MBYTES)
-
Used Swap % (USED_SWAP_PERCENT)
-
Used Swap Mbytes (USED_SWAP_MBYTES)
-
Total Swap Mbytes (TOTAL_SWAP_MBYTES)
-
Page Fault Counts/sec (PAGE_FAULT_COUNTS_PER_SEC)
-
-
If the OS of the monitored host is the Workload Partition (WPAR) environment of AIX V6.1 or later, 0 is displayed in the following fields:
-
CPU % (CPU_PERCENT)
-
Idle % (IDLE_PERCENT)
-
System % (SYSTEM_PERCENT)
