FW: NRPE: Unable to read output - Plugin(event handler)

[Lewis Getschel]

Nathan-
   If I'm following you (which I may not be)...

Your nrpe.cfg command listed here doesn't have ANY arguments shown for 
cycle_tomcat.

Assuming that you're using nrpe's original configuration, it doesn't 
accept any arguments while 'calling' nrpe from your nagios server 
(security issues abound, i.e. dont_blame_nrpe=1).
Therefore, if cycle_tomcat needs any parameters, you need to list them 
along with the script path/name. Here is one of my nrpe.cfg commands:

command[check_fsdisk4]=/usr/lib/nagios/plugins/check_disk -w 10% -c 5% 
-p /dev/sde1

In services.cfg it is simply called with:
check_nrpe!check_fsdisk4

I don't put any parameters in the services.cfg file, just in the 
nrpe.cfg file.

I hope I got what you wanted.
