My Monitor (CHANGEME)

Author	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:

UNAME="/bin/uname"
SWAP="/usr/sbin/swap" 
PSRINFO="/usr/sbin/psrinfo"
MPSTAT="/usr/bin/mpstat"

Modify your clientlaunch.cfg, adding:

[cpu2]
	ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
	CMD $HOBBITCLIENTHOME/ext/cpu2.sh
	LOGFILE $HOBBITCLIENTHOME/logs/cpu2.log
	INTERVAL 5m

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.
