[Nagiosplug-help] check_mailq and check_nrpe = cannot read input

[Erik Cummings]

I have searched and found nothing to help with this, although I've seen several others with the same/similar issues.

When running check_mailq locally I get good output/success.

When running check_mailq via check_nrpe I am having NO luck - "Unable to read output"

I have made a sudo entry to allow nagios user to run check_mailq without a password.

This command from the local host works:
/usr/bin/sudo /usr/lib64/nagios/plugins/check_mailq -w 10 -c 20

This command via NRPE does NOT
/usr/lib64/nagios/plugins/check_nrpe -H XXXXX -c check_mailq -a 10 20

NRPE.cfg excerpt:
command[check_mailq]=/usr/bin/sudo /usr/lib64/nagios/plugins/check_mailq -w $ARG1$ -c $ARG2$ 

sudoers entry (via visudo):
nagios ALL = NOPASSWD: /usr/lib64/nagios/plugins/
	(and yes...once I figure this out I'll restrict that a little more!)

Only "Unable to read output".

All other commands work fine via NRPE.

Any help is greatly appreciated!~!!!!
