[collectd] On $Interval differences between hosts

[Trent W. Buck]

Suppose I have centralized monitoring (i.e. hub-and-spoke), similar to
centralized syslogging.  On the central host (accepts UDP and writes
RRD), I have

    Interval 60

On the nodes (collectd data and write to UDP), I have

    Interval 10

Is a given RRD file updated every ten seconds, or every minute?
