# usage: 
#    check_flexlm.pl license_file
#
# Check available flexlm license managers.
# Use lmstat to check the status of the license server
# described by the license file given as argument.
# Check and interpret the output of lmstat
# and create returncodes and output.
#
# Contrary to the nagios concept, this script takes
# a file, not a hostname as an argument and returns
# the status of hosts and services described in that
# file. Use these hosts.cfg entries as an example
#
#host[anchor]=any host will do;some.address.com;;check-host-alive;3;120;24x7;1;1;1;
#service[anchor]=yodel;24x7;3;5;5;unix-admin;60;24x7;1;1;1;;check_flexlm!/opt/lic/licfiles/yodel_lic
#service[anchor]=yeehaw;24x7;3;5;5;unix-admin;60;24x7;1;1;1;;check_flexlm!/opt/lic/licfiles/yeehaw_lic
#command[check_flexlm]=/some/path/libexec/check_flexlm.pl $ARG1$
#
# Notes:
# - you need the lmstat utility which comes with flexlm.
# - set the correct path in the variable $lmstat.
