'''
Nagios plug-in to pull the Dell service tag and check it
against Dell's web site to see how many days remain. By default it
issues a warning when there is less than thirty days remaining and critical
when there is less than ten days remaining. These values can be adjusted
using the command line, see --help.

#=============================================================================
# TODO: omreport md enclosures, cap the threads, tests, more I suppose
#
# Revision history:
# 2013-05-13 4.1: Catch SSL exceptions from requests module.
#
# 2013-04-09 4.0: Moved to using api.dell.com and changed out urllib2 in
# preference to the requests library.
#
# 2012-10-08 3.0.2: Add support for hyphen dates
#
# 2012-10-07 3.0.1: Dell dropped the counter for days left from their site,
# this is now calculated internally. Add patch for European style dates
# with periods between that numbers.
#
# 2012-09-05 3.0: Use Net-SNMP bindings for python allowing SNMPv3 support. Add
# debugging output using -V, Small cleanups.
#
# 2012-08-23 2.2.3: Merge in patch from Colin Panisset to dedup serials before
# mutex is created
#
# 2012-07-30 2.2.2: Make regex slightly more robust on scrape.
#
# 2012-07-03 2.2.1: Fix version number mismatch, fix urllib exception catch,
# thanks go to Sven Odermatt for finding that.
#
# 2012-01-08 2.2.0: Fix to work with new website, had to add cookie handeling
# to prod the site correctly to allow scrapping of the information.
#
# 2010-07-19 2.1.2: Patch to again fix Dell's web page changes, thanks
# to Jim Browne http://blog.jbrowne.com/ as well as a patch to work against
# OM 5.3
#
# 2010-04-13 2.1.1: Change to deal with Dell's change to their web site
# dropping the warranty extension field.
#
# 2009-12-17 2.1: Change format back to % to be compatible with python 2.4
# and older.
#
# 2009-11-16 2.0: Fix formatting issues, change some variable names, fix
# a file open exception issue, Dell changed the interface so updated to
# work with that, new option --short for short output.
#
# 2009-08-07 1.9: Add smbios as a way to get the serial number.
# Move away from old string formatting to new string formatting.
#
# 2009-08-04 1.8: Improved the parsing of Dell's website, output is now much
# more complete (read larger) and includes all warranties. Thresholds are
# measured against the warranty with the greatest number of days remaining.
# This fixes the bug with doubled or even tripled warranty days being
# reported.
#
# 2009-07-24 1.7: SNMP support, DRAC - Remote Access Controller, CMC -
# Chassis Management Controller and MD/PV Disk Enclosure support.
#
# 2009-07-09 1.6: Threads!
#
# 2009-06-25 1.5: Changed optparse to handle multiple serial numbers. Changed
# the rest of the program to be able to handle multiple serial numbers. Added
# a de-duper for serial numbers just in case you get two of the same from
# the command line or as is the case with Dell blades, two of the same
# from omreport. So this ought to handle blades, though I don't have
# any to test against.
#
# 2009-06-05 1.4 Changed optparse to display %default in help output. Pretty
# up the help output with <ARG> instead of variable names. Add description
# top optparse. Will now use prefer omreport to dmidecode for systems
# that have omreport installed and in $PATH. Note, that you do not have to be
# root to run omreport and get the service tag.
#
# 2009-05-29 1.3 Display output for all warranties for a system. Add up the
# number of days left to give an accurate count of the time remaining. Fix
# basic check for Dell's database being down. Fixed regex to be non-greedy.
# Start and end dates for warranty now takes all warranties into account.
# Date output is now yyyy-mm-dd because that is more international.
#
# 2009-05-28 1.2 Added service tag to output for nagios. Fixed some typos.
# Added command-line option for specifying a serial number. This gets
# rid of the sudo dependency as well as the newer python dependency
# allowing it to run on older RHEL distros. justin@techadvise.com
#
# 2009-05-27 1.1 Fixed string conversions to do int comparisons properly.
# Remove import csv as I am not using that yet. Add a license to the file.
