#@---------------------------------------------------
#@ History
#@---------------------------------------------------
#@ Date   : 20080820
#@ Author : David Ligeret
#@ Reason : Initial release
#@---------------------------------------------------
#@ Date   : 20080821
#@ Author : David Ligeret
#@ Reason : Add verbose mode
#@---------------------------------------------------
#@ Date   : 20090219
#@ Author : Joshua Daniel Franklin
#@ Reason : Add try/except to catch AuthError and CIMError
#@---------------------------------------------------
#@ Date   : 20100202
#@ Author : Branden Schneider
#@ Reason : Added HP Support (HealthState)
#@---------------------------------------------------
#@ Date   : 20100512
#@ Author : Claudio Kuenzler www.claudiokuenzler.com
#@ Reason : Combined different versions (Joshua and Branden)
#@ Reason : Added hardware type switch (dell or hp)
#@---------------------------------------------------
#@ Date   : 20100626/28
#@ Author : Samir Ibradzic www.brastel.com
#@ Reason : Added basic server info
#@ Reason : Wanted to have server name, serial number & bios version at output
#@ Reason : Set default return status to Unknown
#@---------------------------------------------------
#@ Date   : 20100702
#@ Author : Aaron Rogers www.cloudmark.com
#@ Reason : GlobalStatus was incorrectly getting (re)set to OK with every CIM element check
#@---------------------------------------------------
#@ Date   : 20100705
#@ Author : Claudio Kuenzler www.claudiokuenzler.com
#@ Reason : Due to change 20100702 all Dell servers would return UNKNOWN instead of OK...
#@ Reason : ... so added Aaron's logic at the end of the Dell checks as well
#@---------------------------------------------------
#@ Date   : 20101028
#@ Author : Claudio Kuenzler www.claudiokuenzler.com
#@ Reason : Changed text in Usage and Example so people dont forget to use https://
#@---------------------------------------------------
#@ Date   : 20110110
#@ Author : Ludovic Hutin (Idea and Coding) / Claudio Kuenzler (Bugfix)
#@ Reason : If Dell Blade Servers are used, Serial Number of Chassis was returned
#@---------------------------------------------------
#@ Date   : 20110207
#@ Author : Carsten Schoene carsten.schoene.cc
#@ Reason : Bugfix for Intel systems (in this case Intel SE7520) - use 'intel' as system type
#@---------------------------------------------------
#@ Date   : 20110215
#@ Author : Ludovic Hutin
#@ Reason : Plugin now catches Socket Error (Timeout Error) and added a timeout parameter
#@---------------------------------------------------
#@ Date   : 20110217/18
#@ Author : Ludovic Hutin / Tom Murphy
#@ Reason : Bugfix in Socket Error if clause
#@---------------------------------------------------
#@ Date   : 20110221
#@ Author : Claudio Kuenzler www.claudiokuenzler.com
#@ Reason : Remove recently added Timeout due to incompabatility on Windows
#@ Reason : and changed name of plugin to check_esxi_hardware
#@---------------------------------------------------
#@ Date   : 20110426
#@ Author : Claudio Kuenzler www.claudiokuenzler.com
#@ Reason : Added 'ibm' hardware type (compatible to Dell output). Tested by Keith Erekson.
#@---------------------------------------------------
#@ Date   : 20110426
#@ Author : Phil Randal
#@ Reason : URLise Dell model and tag numbers (as in check_openmanage)
#@ Reason : Return performance data (as in check_openmanage, using similar names where possible)
#@ Reason : Minor code tidyup - use elementName instead of instance['ElementName']
#@---------------------------------------------------
#@ Date   : 20110428
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : If hardware type is specified as 'auto' try to autodetect vendor
#@ Reason : Return performance data for some HP models
#@ Reason : Indent 'verbose' output to make it easier to read
#@ Reason : Use OptionParser to give better parameter parsing (retaining compatability with original)
#@---------------------------------------------------
#@ Date   : 20110503
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : Fix bug in HP Virtual Fan percentage output
#@ Reason : Slight code reorganisation
#@ Reason : Sort performance data
#@ Reason : Fix formatting of current output
#@---------------------------------------------------
#@ Date   : 20110504
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : Minor code changes and documentation improvements
#@ Reason : Remove redundant mismatched ' character in performance data output
#@ Reason : Output non-integral values for all sensors to fix problem seen with system board voltage sensors
#@          on an IBM server (thanks to Attilio Drei for the sample output)
#@---------------------------------------------------
#@ Date   : 20110505
#@ Author : Fredrik Aslund
#@ Reason : Added possibility to use first line of a file as password (file:)
#@---------------------------------------------------
#@ Date   : 20110505
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : Simplfy 'verboseoutput' to use 'verbose' as global variable instead of as parameter
#@ Reason : Don't look at performance data from CIM_NumericSensor if we're not using it
#@ Reason : Add --no-power, --no-volts, --no-current, --no-temp, and --no-fan options
#@---------------------------------------------------
#@ Date   : 20110506
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : Reinstate timeouts with --timeout parameter (but not on Windows)
#@ Reason : Allow file:passwordfile in old-style arguments too
#@---------------------------------------------------
#@ Date   : 20110507
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : On error, include numeric sensor value in output
#@---------------------------------------------------
#@ Date   : 20110520
#@ Author : Bertrand Jomin
#@ Reason : Plugin had problems to handle some S/N from IBM Blade Servers
#@---------------------------------------------------
#@ Date   : 20110614
#@ Author : Claudio Kuenzler (www.claudiokuenzler.com)
#@ Reason : Rewrote file handling and file can now be used for user AND password
#@---------------------------------------------------
#@ Date   : 20111003
#@ Author : Ian Chard (ian@chard.org)
#@ Reason : Allow a list of unwanted elements to be specified, which is useful
#@          in cases where hardware isn't well supported by ESXi
#@---------------------------------------------------
#@ Date   : 20120402
#@ Author : Claudio Kuenzler (www.claudiokuenzler.com)
#@ Reason : Making plugin GPL compatible (Copyright) and preparing for OpenBSD port
#@---------------------------------------------------
#@ Date   : 20120405
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : Fix lookup of warranty info for Dell
#@---------------------------------------------------
#@ Date   : 20120501
#@ Author : Craig Hart
#@ Reason : Bugfix in manufacturer discovery when cim entry not found or empty
#@---------------------------------------------------
#@ Date   : 20121027
#@ Author : Claudio Kuenzler (www.claudiokuenzler.com)
#@ Reason : Added workaround for Dell PE x620 where "System Board 1 Riser Config Err 0: Connected"
#@          element outputs wrong return code. Dell, please fix that.
#@          Added web-link to VMware CIM API 5.x at top of script. 
#@---------------------------------------------------
#@ Date   : 20130424
#@ Author : Claudio Kuenzler (www.claudiokuenzler.com)
#@ Reason : Another workaround for Dell systems "System Board 1 LCD Cable Pres 0: Connected"
#@---------------------------------------------------
#@ Date   : 20130702
#@ Author : Carl R. Friend
#@ Reason : Improving wrong authentication timeout and exit UNKNOWN
#@---------------------------------------------------
#@ Date   : 20130725
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : Fix lookup of warranty info for Dell
