By checking the swap usage. Basically, when a system starts swapping
performance will go downhill very, very fast. The disk is several hundred
orders of magnitude slower than the RAM. If you have high swap usage, you
should buy more RAM for your servers (or modify whatever programs are
running on them).

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
