[hobbit] Hobbit client to monitor Solaris RAID devices

20 Jun 2008

      The last one seems to have lost something in translation. Please accept
my apologies and use this (working) version!
#!/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.

This has been tested with BB 1.8c and Hobbit 4.2.0

Tested on :

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.
