# 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.

# Set up the initial colour

# Get the svcs header line first

# Scan through the svcs -a list. Use -a to ensure we get everything.
