Ummm, how about a situation where you have a steadily
increasing work load (more customers?) and want to have
decent statistics of your servers to determine exactly
what parts to upgrade and/or if you need to put extra
machines into service?
I agree that *any* statistics become useless after some
time in a completely static situation, but thruth is that
the number of internet users is still increasing and the
workload on servers is doing the same ;)
