are modules initiated at every collection time, or is it initiated at
ganglia start up and kept through the runtime?
I'm asking because I am looking at doing per second metrics based on
the difference between the previously read value and the currently
read value. The code (dstat, from the DAG repository) conveniently
gives me nice classes for everything i'm looking at pulling out
(interrupts per second, context switches per second, etc), and even
goes so far as to check the value since the last time run, but of
course, this produces a big spike in the second run and a 0 value in
the first (thus, giving you a spike). I figure I can extract out the
values a couple of times to get rid of the spike in the instantiation
and then go from there.
