Henrik,
Works great! Thanks so much!
For those that dont want to read the c code, you need to replace the title in your [mrtg] stanza in the hobbitgraph.cgi file with something like the following:
TITLE exec:/usr/local/hobbit/server/bin/mrtg-title.sh
... or wherever you saved the shell script below to.
One small change I made to the shell script was to change the MRTGTITLE capture line to:
MRTGTITLE=grep -i "Title\[$MRTGSET\]:" /usr/local/mrtg/cfg/$HOSTNAME.cfg | cut -d: -f2-
...since our hosts our configured on a per-file basis and included from the main mrtg.conf
Thanks again! -Eric

Any way to have Hobbit read the Title Tag in the MRTG Configuration File and thus label the graphs accordingly?
Not directly, but the attached patch lets you have an external script decide what the title is.
I've tried it on my own MRTG setup and it appears to work fine. I used this script to generate the title from mrtg.cfg (note that you may have to change the permissions on mrtg.cfg to let the CGI user read it):
#!/bin/sh
HOSTNAME="$1"; shift GTYPE="$1"; shift LEGEND="$1"; shift
RRD="$1"; shift #echo "RRD=$RRD, rest is $*" >>/tmp/title.log
MRTGSET="echo $RRD | sed -e's/\.rrd$//'"
#echo "MRTGSET=$MRTGSET" >>/tmp/title.log
MRTGTITLE=grep -i "Title\[$MRTGSET\]:" /etc/mrtg.cfg | cut -d: -f2-
#echo "TITLE=$MRTGTITLE" >>/tmp/title.log
echo "$MRTGTITLE $LEGEND" exit 0
