[Nagiosplug-help] NRPE: Unable to read output

[Brian Tomjack]

Marc thanks for more ideas,

The requiretty was in there, i have hashed that item out.

modified the nrpe config to be
command[check_mailq]="/usr/bin/sudo 
/usr/local/nagios/libexec/check_mailq -w 120 -c 175"

locally the command still works. when it is forced through nrpe i still 
get a unable to read output error unfortunately.

so i tried the addition of the 2>&1 to the end. appending that in the 
nrpe config and reloading nrpe still gave a unable to read output error 
on the nagios side. locally when executing with the 2>&1 on the end 
there was no error. the console output:
sudo /usr/local/nagios/libexec/check_mailq -w 120 -c 175 2>&1
OK: mailq (119) is below threshold (120/175)|unsent=119;120;175;0

which is the same output as when the 2>&1 is left off.


Im beginning to think that maybe nrpe just does not want to watch my 
mail queue on this server heh.


thanks,

Brian
