Anymore? So it worked before? What changed?  Stuff generally doesn't
stop working unless something was changed.

The notification commands below have macros in.  How did you execute
the same command?  Did you increase the debugging levels in nagios to
see what it was executing?

1. Increase the debugging levels to see what the macros are
2. Make sure there are entries in the logs saying it generated the
alerts
