swapinfo will give info on whether the system has paged/swapped out data.

Glance is a way to monitor a process's action, for instance paging.

sar,vmstat, etc. might give info on a system level.

If you use vmstat look at the PO (page outs). If this number is high, then your system is paging.

Bring up the glance ascii interface:

# glance

Hit "m" to take you to the memory page.

Check for "deactivations".

If your system is forced to "page out" for memory pressure reasons, there will be deactivations.

If deactivations is "0", then you are not paging out.

This doesn't help in the middle of the night, when you aren't at work, but it will tell you something during the day.

BTW, we don't page out - we bought enough memory to cover that.
