Drew,

Your counters probably reset a couple of times during the month, when they
reach some maximum value. Or perhaps because somebody power cycles the
switch.

So, no, it's not a good idea to look at the counter on day 1 and on day 30
and compare them. Check it every 5 minutes and store it in a database.
That way, the same system can do aggregate or 95th percentile, it's all in
the report script you write.
