You can do this with a custom script. I believe there is a thrah in the archive for this but here is what I came up with to handle it:
XYMON_NAME=`$XYMON $XYMONSERVERHOSTNAME "hostinfo host=$BBHOSTNAME" | $SED -e 's/|/\n/g' | $GREP NAME | $CUT -d: -f2`

Subject: [Xymon] alert scripting
In our hosts.cfg file, we include a NAME setting to standardize a naming convention for the several xymon clients. In creating alert scripts, I would like to display this name, rather than the clients hostname. Is this possible, without manually grepping through the hosts.cfg file? It appears that BBHOSTNAME displays the hostname rather than the value set by name.
Suggestions appreciated.
