System Overview (6.0) (historical report indicating the system operation status)

Active CPUs

Number of processors

CPU %

Processor usage rate (%). This is also the average value for all processors.

Effective Free Mem %

Percentage of the physical memory size actually available to applications (%)

Effective Free Mem Mbytes

Size of the physical memory actually available to applications (megabytes)

Free Swap %

In Windows:

Percentage of unused space in the virtual memory area (%)

In UNIX:

Percentage of unused space in the swap area (%)

Free Swap Mbytes

In Windows:

Size of the unused space in the virtual memory area (megabytes)

In UNIX:

Size of the unused space in the swap area (megabytes)

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

In Windows:

Size of the virtual memory area (megabytes)

In UNIX:

Size of the swap area (megabytes)

Effective Used Mem %

Actual usage rate of physical memory (%)

Effective Used Mem Mbytes

Actual size of the used physical memory area (megabytes)

Used Swap %

In Windows:

Virtual memory usage rate (%)

In UNIX:

Swap area usage rate (%)

Used Swap Mbytes

In Windows:

Size of the virtual memory area used (committed) (megabytes)

In UNIX:

Size of the swap area used (megabytes)

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.
