Description

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
