This is such a common misconception that the development team should
consider removing the name field from the data_source configuration line
entirely.
Fundamentally, cluster names come from the gmond.conf files. The names of
datasources exist only to confuse the hell out of you and create bugs. You
need to change those gmond.conf's to match the cluster names you want.
IIRC, it's a good idea for the datasources lines to match those because they
actually are used in a few places and having them *not* match just confuses
the next guy who maintains your system.
