====== My Monitor (CHANGEME) ======

^ Author | [[ butchdeal@yahoo.com | Butch Deal ]] |
^ Compatibility | Xymon 4.2 |
^ Requirements | unix, dmidecode for linux |
^ Download | None |
^ Last Update | 2009-06-02 |

===== Description =====
Monitors lots of extra CPU and system related bits. Works on Linux (RH & SuSe), Solaris, and now MacOS X (Darwin). Removed the need to install prtdiag on Linux, and added more complete relese version info.
Added some support for Solaris 10 zones and for dual core Ultra sparc IV.
===== Installation =====
=== Client side ===
add these lines to hobbitclient.cfg:
<code>
UNAME="/bin/uname"
SWAP="/usr/sbin/swap" 
PSRINFO="/usr/sbin/psrinfo"
MPSTAT="/usr/bin/mpstat"
</code>

Modify your clientlaunch.cfg, adding:
<code>
[cpu2]
	ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
	CMD $HOBBITCLIENTHOME/ext/cpu2.sh
	LOGFILE $HOBBITCLIENTHOME/logs/cpu2.log
	INTERVAL 5m
</code>
edit cpu2.sh for proper path to sudo and dmidecode.  Set up sudo so that dmidecode can be run without password.  (script tried both /usr/local/bin/sudo and /usr/bin/sudo).
=== Server side ===

# bb-cpu2.sh: Sun Enterprise Server check - BB external script test
#             ^ and now Linux
#
#####  Purpose is to report back to a central server, all "standard"
#####    detailed information about network, disk, volume, cpu, memory
#####    which is not reported thru regular "easy" checks.
#####
#
# version 1.0
# version 2.0 - includes uname and prtdiag checks too
# version 2.1 - properly uses $CAT instead of cat
# version 2.2 - properly uses $MACHINE instead of `uname -n` in bb-hosts check
# version 2.4 - properly uses $THIS_HOST instead of $MACHINE due to fqdn using
#                 comma in name - thanks Craig Cook
# version 3.0 - updates to work properly with BB 1.6
#               properly uses `uname -i` for platform check on E10K
# version 3.1 - changed /tmp to $BBTMP
#                       cpu2 to $TEST
#                       $THIS_HOST to $MACHINE
#               removed code that checked for the existence of "cpu2"
#                 after the server name in bb-hosts
#               moved comment explaining purpose of script to start of code
#               removed <BLOCKQUOTE> statements
# version 3.2 - made swap check optional
#               Applied Todd Jimenez style get_header and get_footer functions
#               added check for bbsys.local vars being set
#               changed wc to $WC
#               restored functionality to check for the existence of "cpu2"
#                 after the server name in bb-hosts, but now optional
#               changed &red and &yellow to variables
# version 3.3 - Added changes suggested by Andrew Clarke
#               - skip tests that involve uname -x on solaris 2.5.1, since it
#                 does not support this switch.
#               - [ "SWAP_INFO" = "Y" ] was missing a $
#               - new comment line for testing
#               - swap -s on solaris 2.51 returns "1"
# version 3.5 - Added support for Linux
#               - physical cpu count for both Solaris and Linux
#               - OS release information for both Solaris and Linux
#               - have not tested SWAP_INFO for Linux
# version 3.6 - Added some support for Mac OS X (Darwin) 
#               - modularised some of the procedures
#               - removed need for prtdiag on Linux
# version 3.9 - Added some support for Solaris zones
#               - added support for dual core Ultra sparc IV
# version 3.9.1 - started support for Sun4v Niagara chips
# version 3.10 - Added more dmidecode entries

########################################
# NOTE
# This has been tested with BB 1.8c and 1.9e
# 
# Tested on :
#   Sun Solaris, Linux, Darwin
########################################

###########################################################################
# INSTALLATION
#  step 1  - update bb-bbexttab to include this bb-cpu2.sh
#            (older BB versions update EXT section of the bbdef.sh script)
#
#  step 2 - if you want this script to show swap info uncomment
#             SWAP_INFO="Y"
#           NOTE: it does not do any error checking on swap space though
#
#  step 3 - copy lines mentioned to bbsys.local (without the #'s)
#
#  step 4 - 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   # cpu2
#
#  step 5 - restart Big Brother
#
#  *Linux* 
#       install dmidecode to determin actual CPU count
#
# NOTE - the TEST variable in the configuration section, this is the name
#        used as the column header and in the BB-HOSTS file.
