Fields

Table 6‒48: Description of fields (Memory Used Status (real-time report indicating the physical memory usage status in the system))

Field name

Description

Free Mem %

In Windows:

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

In UNIX:

Percentage of the size of unused physical memory (%).

It does not include the amount of releasable areas assigned to the caches and buffers.

Free Mem Mbytes

In Windows:

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

In UNIX:

Size of unused physical memory (megabytes).

It does not include the amount of releasable areas assigned to the caches and buffers.

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)

Page Fault Counts/sec

Frequency of page faults (times/second)

Page-In Pages/sec

Rate at which pages were paged in (pages/second)

Page-Out Pages/sec

Rate at which pages were paged out (pages/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

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)

Used Mem %

Physical memory usage rate (%)

Used Mem Mbytes

Size of the physical memory area used (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)
