Activate debug mode in nrpe.cfg an have a look on your syslog what's happening when the check is called.

		Hi all,

		I'm trying to check for the presence of a particular process on a remove machine using NRPE and check_procs with a -a or -C argument.  I have defined on the remote machine's nrpe_local.cfg:
		command[check_foo]=/usr/nagios/plugins/check_procs -c 1:1 -C foo
		Running a similar command locally on that machine works fine:
		$ /usr/lib/nagios/plugins/check_procs -c 1:1 -C foo
		PROCS OK: 1 process with command name 'foo'
		But when I try to run the command from the Nagios server, I get the following result:
		$ /usr/lib/nagios/plugins/check_nrpe -H remote.host -c check_foo
		NRPE: Unable to read output
		Whereas other monitored services work fine:
		$ /usr/lib/nagios/plugins/check_nrpe -H remote.host -c check_procs
		PROCS OK: 97 processes

	 Just to be certain, did you restart the nrpe daemon on remote.host after modifying its nrpe.cfg file?
