Hobbit client to monitor Solaris RAID devices

All,
I have been using a script called bb-raid.sh for a few years to monitor
Solaris meta devices. I then came across a Solaris server using raidctl
for hardware raid, so I modified bb-raid.sh to monitor this one as well.
Here is the code. Feel free to use it as you wish:

#!/bin/sh
#
# meta: Sun Enterprise Server check - BB external script test
#
##### Purpose is to report back to a central server, all Solaris
##### DiskSuite RAID software faults.
#####
#
# version 1.0
# version 2.0 - properly uses $THIS_HOST instead of $MACHINE due to fqdn
using
# comma in name
# removed all direct program calls in favor of env vars in
bbsys.*
# changed /tmp to $BBTMP
# meta to $TEST
# $THIS_HOST to $MACHINE
# removed code that checked for the existance of "meta"
# after the server name in bb-hosts
# moved comment explaining purpose of script to start of
code
# caused output of metadb, metastat, and metahs to be
displayed
# on the web page
# version 2.1 - Warns if default values are not used
# Applied changes by Todd Jimenez
# - created get_header and get_footer functions
# - set summary value
# - added &red to red alerts
# - added &yellow to yellow alerts
# restored functionality to check for the existence of
"meta"
# after the server name in bb-hosts, but now optional
# version 2.2 - Change status to &yellow when disk is resyncing.
# version 2.3 - Added code to check for raidctl command and perfrom raid
checks
# using that if it's there.
# Using this version REQUIRES sudo !
# raidctl(1m) on Solaris can only be run as root. Sudo is
a
# nice workaround.

########################################
# NOTE
# This has been tested with BB 1.8c and Hobbit 4.2.0
#
# Tested on :
# Sun 220R, 420R, E250/450, E4500

# INSTALLATION
# step 1 - update bb-bbexttab to include this meta
# (older BB versions update EXT section of the bbdef.sh
script)
#
# step 2 - copy lines mentioned to bbsys.local (without the #'s)
#
# step 3 - if you are using an older version of BB without bb-bbexttab
# and you don't want this run on every client uncomment
# CHECK_BB_HOSTS="Y" and add the name of this $TEST to
# bb-hosts for this client. eg.
# myserver1.domain.com # meta
#
# step 4 - If you have sudo installed need to use the raidctl control,
# add the following line into your /etc/sudoers file:
# hobbit ALL=(root) NOPASSWD:/usr/sbin/raidctl -l
# step 5 - restart Big Brother
#
# NOTE - the TEST variable in the configuration section, this is the
name used
# as the column header.
