# Another Plugin for Nagios to monitor the hylafax-queue
# Written by T. Bruentjen (alte-schlonte at gmx dot com)
# Date: 2007/12/06
#
# Usage: ./check_faxq -<warn> -<crit>
#
# Output:
# This plugin gives a number of faxes with errors 
#
# Exit Codes:
# 0 OK       The number of faxes in the queue are under the warning
#            or under the critical threshold
# 1 Warning  Number of faxes with errors in the queue above "warning" threshold
# 2 Critical Number of faxes with errors in the queue above "critical" threshold
# 3 Unknown  One of the needed services are not running e.g. hfaxd,faxgetty,faxq
#
