The "step" setting should be configurable at runtime and per
plugin.  Haven't looked at your main loop but it shouldn't
be very hard to do.

Now as far as the RRAs go, you're absolutely right.  You
can't hard code these.  Again, my advice is to make them
configurable per plugin, at runtime.  (Default RRAs as well)

You will never please everyone by setting your own RRAs, even
if you do it dynamically.  Allowing runtime configuration
makes collectd far more generic which will make it more usable
by more people.

Hope this helps.
