# Nagios plugin to pull the Dell service tag and check it 
# against Dell's website 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.

some servers have multiple lines of support on the dell site. the script only uses the bottom line though occasionally one of the other lines has longer support.

Someone that knows python could really clean this up and probably easily add some features. (please do).
