Swapper

Three probes trace the activity of the swapper.

• The swapout_process probe traces the swapping out of a process address space; it records the process identifier and the total number of pages either freed or queued for output.

• The swapout_lwp probe traces the swapping out of an LWP's stack pages; it records the LWP's identity and the number of pages queued for output.

• The swapin_lwp probe traces the swapping in of an LWP's stack pages; it records the LWP's identity and the number of stack pages brought in.
