[hobbit] MRTG-based Graphs in Trends Section

[Schwimmer, Eric E *HS]

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

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


Regards,
Henrik
