It's done: http://xymonton.trantor.org/doku.php/monitors:smf.sh
I hope I got the syntax right, it all looks good to me.

Funny that. About a year ago I discussed using that method with a
colleague.
We never got that far, and I forgot all about it.
And excellent way to do it.
Have you considered posting your script on Xymonton?

I have a script that is one step further than yours, the main difference
being that I have defined the services to be monitored in the
client-local.cfg file as you want:
In client-local.cfg for example:
[nmc-dhcp1]
log:/var/adm/messages:10240
svc:/network/ssh:default|svc:/site/network/dhcpd:default
Data from this file is sent to the client (in this case a server called
nmc-dhcp1) and stored in $BBTMP/logfetch.$MACHINEDOTS.cfg, so in the
client-side script I have:
SVCS=`grep '^svc:' $BBTMP/logfetch.$MACHINEDOTS.cfg`
I was being lazy so have separated the services with the | symbol in
client-local.cfg, this means I can then use the following code with no
pre-processing:
svcs -a | ${EGREP} "${SVCS}" > $SVCFILE
The reason I store the 'svcs -a' output is because I include it in the
data sent back to Xymon.
Service states are checked using the following code:
cat $SVCFILE | while read SVC
do
STATE=`echo ${SVC} | ${AWK} '{print $1}'`
case "${STATE}" in
'uninitialized'|'offline'|'degraded')
if [ "${COLOUR}" != "RED" ]
then
COLOUR="YELLOW"
fi
;;
'maintenance'|'disabled')
COLOUR="RED"
;;
esac
echo ${COLOUR} > $COLOURFILE
done
COLOUR=`cat ${COLOURFILE}`
To be honest I don't know why I am storing the colour in a file and then
re-reading it outside the loop, the value shouldn't change at the end of
the while loop. This script was thrown together so it's likely I
intended to remove it but forgot.
Anyway, after that loop I call $BB and pass it all the parameters.
It doesn't have the options that you want, but it does allow for
different return colours depending on the return state. I coded it to
return RED if a service is in a disabled state since I want to monitor
specific services rather than all of them.
The final code is here:

#!/bin/sh
# A Hobbit script to examine specific Solaris 10 services.
# Author: Martin Ward 19 Feb 2008.
# Version: 1.0 - Initial version.
# V1.1 Script now takes the list of services to monitor from the server
# via the logfetch file.
# SVCS is a list of services to examine the status of. Each name must be
# specific enough to make it unique in the output from the 'svcs -a'
command.
# Separate each service with a | so that we can use ${EGREP} to search
for them.
# The services themselves are configured on the Hobbit server in the
# ~hobbit/server/etc/client-local.cfg file. The line will look something
like:
# svc:/network/ssh:default|svc:/site/tftpd:default
# Verify existence of the config file
if [ ! -f $BBTMP/logfetch.$MACHINEDOTS.cfg ]
then
echo "Unable to retrieve services descriptions."
exit 1
fi
SVCS=`grep '^svc:' $BBTMP/logfetch.$MACHINEDOTS.cfg`
# The name of the column in Hobbit
COLUMN=smf
# COLOUR defaults to green
COLOUR=GREEN
# When you modify a variable inside a while loop its value is local to
that
# loop. This means that when you reach the end of the loop the variable
will
# be the same value that it was before the loop was entered. For this
reason
# we have to store the services and colour in temporary files.
SVCFILE=/tmp/svcs.$$
COLOURFILE=/tmp/svcs.colour.$$
# Set up the initial colour
echo "WHITE" > $COLOURFILE
# Get the svcs header line first
MSGH=`svcs -a | head -1`
# Scan through the svcs -a list. Use -a to ensure we get everything.
svcs -a | ${EGREP} "${SVCS}" > $SVCFILE
cat $SVCFILE | while read SVC
do
STATE=`echo ${SVC} | ${AWK} '{print $1}'`
case "${STATE}" in
'uninitialized'|'offline'|'degraded')

done
COLOUR=`cat ${COLOURFILE}`
# Tell Hobbit about it
