/usr/local/nagios/libexec/check_nrpe -H 192.168.1.4 -t 30 -c check_init_service -a 'amavisd'
NRPE: Unable to read output

Running Nagios XI 5.6.10
CentOS 7

Found a FAQ with this error, and tried those fixes already, and nada.

NRPE had to be installed via YUM, since the agent installer failed.

Any help would be greatly appreciated.

Hello David,

Thanks for joining the support forum. Welcome Aboard!

Did you add the command definition to the nrpe.cfg file and re-start nrpe? Also, let's verify the paths are set correctly? What is the output to the following command:

Code: Select all

find / -name check_init_service

Log in as nagios , su - nagios, user and test the check command locally on the host running NRPE. Are you able to get the correct output?
