I wrote a mon script to monitor swap use because catching systems when memory use gets
excessive before they go Oom is a good thing.
When I deployed it I was notified of one of my servers which had 99% of the 2G of swap
used but also 7G of "buff/cache" memory according to top and seemed to be
running nicely like that.
Would it give a better result to ignore the amount of swap in use and instead monitor the
percentage of RAM used for buff/cache?

What about reporting both? Then users could get a feel for how the
balance pans out for them, I figure. (Assuming that the script is
destined for the wild?)
This aging host is growing slow, and checking up on what happens
especially when iceweasel ploughs into treacle, would be useful.
Mind you, sometimes X just locks up, and I'd have to find and fire up
another host to whack it through ssh. Reset works.

But I
try to avoid adding useless features and to make defaults that are reasonably
useful.

I've been meaning to get into monit which can restart things automatically.
