   6 # Check available flexlm license managers.
   7 # Use lmstat to check the status of the license server
   8 # described by the license file given as argument.
   9 # Check and interpret the output of lmstat
  10 # and create returncodes and output.

  12 # Contrary to the nagios concept, this script takes
  13 # a file, not a hostname as an argument and returns
  14 # the status of hosts and services described in that
  15 # file. Use these hosts.cfg entries as an example
  16 #
  17 #host[anchor]=any host will do;some.address.com;;check-host-alive;3;120;24x7;1;1;1;

  22 # Notes:
  23 # - you need the lmstat utility which comes with flexlm.
  24 # - set the correct path in the variable $lmstat.
