All RRD files are updated in "the right" interval. I.e., RRDs containing
data from some node are updated using a ten seconds interval and those
belonging to the central server are updated using a 60 seconds interval.

Each plugin "knows" the interval with which it's queried and passes that
information along when dispatching data to collectd. This information is
also transferred over the network and, thus, available on the server as
well.

HTH,
Sebastian
