Is one of the hostnames a substring of the other one? IIRC, the parameter
sent via "host=" is done as a PCRE match. If you have a whole hostname,
adding \b before or after might help.

You can use "hostinfo clone=$BBHOSTNAME" to do an exact match, which will
also break out data into different lines finally.

Finally, I think $XMH_RAW is available in the environment of scripts from
xymond_alert itself. If so (it might have been a patch -- I forget :/ )
that would save you a callback into xymond for the data.


HTH,
