I'm trying to use an external command with the nsclient++. but in Nagios get the message No output returned from plugin.
When I try the command from the commandline it is working.
echo "Warning: appl2"
Running the command I get
./check_nrpe -H x.x.x.x -p 5666 -c testappl2
But within nagios web I get: No output returned from plugin
I also use check_nrpe for some services and uptime and these are reported correctly within nagios
