Am I missing some kind of flag to report "messages" in service or command.cfg?

No. Was '<some message here>' in the first line of output from your plugin?

At the barest minimum, your plugin needs to check something, exit with the correct exit code for the state and to output one line of text for display in the GUI. There are other things it might do and this doc represents the standards for a 'good' plugin (including return codes)-- http://nagiosplug.sourceforge.net/developer-guidelines.html

Not too much... This document will help you identify what's different - http://nagios.sourceforge.net/docs/3_0/whatsnew.html
