Chris,

OK, slight confusion..

You are sending stats, but it is not from a FQDN..

We are getting stats from "oracle", which appears to be:

node249-201.sim.db.erau.edu

Since this appears to be a local machine feeding from your dish, stats may
not be necessary, but if you are going to send them we would like to plot
them and we need a fully qualified domain name to do so. This can be set
in ldmadmin..

Sooo, instead of oracle if it could be oracle.db.erau.edu that would be
great!


Sorry for the confusion..

Cheers,

Jeff
