I think the question relates to the fact that "Used" pages are not
always *actually* in use.
But it seems that this is not a very important question. The important
thing to monitor is that the percentage of used does not get close to
the max. But also, note that the maxsize can be larger than the
underlying disk storage available space. This can be dangerous. It's
always important to monitor both the used/max percentage as well as the
used% of the underlying disk storage.
Now that we're on this topic. And this is only an academic question,
probably: I'm wondering what are olmMDBPagesFree? It seems intuitive
that (max - used) would equate to free, but it does not. Are "free"
pages pages that were once used?
