Using NSKCOM to Monitor and Alter Swap Files

A report such as the following is sent to your home terminal:

The difference between the creates and releases equals the current number of
reservations.

The difference between allocates and frees is the actual number of pages currently
being used for storing swap data.

This actual current usage can be at most equal to the number of Reserved CPU
Pages at any given time.

For more information about NSKCOM, see the Kernel-Managed Swap Facility (KMSF)
Manual
