The plugin above is not network aware and simply runs the command
`omreport chassis temps` on the host it is run on and parses that
output. It accepts no command line arguments other than a -v for verbose
output. You can not pass it warning and critical thresholds as it
figures those out from the "Maximum Warning" and "Maximum Failure"
output of omreport. Your service definition check command should simply
be --

check_command check_nrpe!nagios_check_temps

presuming that you have a 'nagios_check_temps' command definition in
your nrpe.cfg on the remote machine ala --

command[nagios_check_temps]=/path/to/nagios_check_temps

and nagios_check_temps is installed on the machine you are wanting to
check the temperature on in the location specified in the nrpe.cfg
command definition. The command definition that you included above isn't
used at all, at least by the service definition you included.

You didn't give any indication about what the actual problem was you
were experiencing so that's about all I can tell you.
