System Overview (historical report indicating the system operation status)
- Organization of this page
Overview
The System Overview report displays the minute-by-minute system operation status over the past hour. The display format is a line graph.

Fields
Field name |
Description |
---|---|
Active CPUs |
Number of processors |
CPU % |
Processor usage rate (%). This is also the average value for all processors. |
Free Mem % |
Percentage of the physical memory size actually available to applications (%) |
Free Mem Mbytes |
Size of the physical memory actually available to applications (megabytes) |
Free Swap % |
|
Free Swap Mbytes |
|
Idle % |
Percentage of the time the processor was in idle status (%). This is also the average value for all processors. |
Page Fault Counts/sec |
Frequency of page faults (times/second) |
Page Scan Counts/sec |
Frequency of page scans (times/second) |
Paging Pages/sec |
Rate at which pages were being paged in and out when a page fault occurred (pages/second). This is the total of the Page-In Pages/sec and Page-Out Pages/sec fields. If this value exceeds 5 continuously, the memory might be the bottleneck in the system. |
Polling Time |
Time the performance data was collected on the PFM - RM host |
Pool Nonpaged KBytes |
Size of the physical memory that cannot be paged out and that was used to allocate area when system components executed tasks (kilobytes). Normally, if server activity has not increased but the value of this field keeps increasing, a process that causes a memory leak might be executing. |
Run Queue Avg 5 min |
Average number of threads waiting in the execution queue for the past 5 minutes. In the case of UNIX (HP-UX, Solaris, and AIX), this value does not include the number of threads waiting for I/O. In Linux, this value does contain the number of threads waiting for I/O. |
Swap-In Pages/sec |
Frequency of page loading by swap-in processing (pages/second). In AIX, this is the frequency of page loading by swap-in processing only in the paging area (pages/second). |
Swap-Out Pages/sec |
Frequency of page removal by swap-out processing (pages/second). In AIX, this is the frequency of page removal by swap-out processing only in the paging area (pages/second). |
System % |
Usage rate for a processor that was executed in the kernel mode (%). This is also the average value for all processors. |
Target Host Time |
Time the performance data was collected on the monitored host |
Total Mem Mbytes |
Size of the physical memory (megabytes) |
Total Swap Mbytes |
|
Used Mem % |
Physical memory usage rate (%) |
Used Mem Mbytes |
Size of the physical memory area used (megabytes) |
Used Swap % |
|
Used Swap Mbytes |
|
User % |
Usage rate for a processor that was executed in the user mode (%). This is also the average value for all processors. |
Wait % |
Percentage of the time the processor was in I/O wait status (%). This is also the average value for all processors. |
