Nagios Support Forum

Hello,

We ran below commands as suggested by you. PFA the output for the same.

Also, we removed nrpe using below command:
yum remove nrpe

and again we restarted nrpe and we are getting below error:

[root@EU2XAPL060 etc]# systemctl start nrpe.service
Failed to start nrpe.service: Unit not found.
[root@EU2XAPL060 etc]# systemctl status nrpe.service
Unit nrpe.service could not be found.
[root@EU2XAPL060 etc]#

And in Nagios XI, we are getting other error now:
(Return code of 255 is out of bounds)

The Linux NRPE Agent installer, sets up the agent to be started by xinetd so to load the agent for starting up, run this. Then to test is out, run the following from the Nagios XI server to see if it returns the version of the agent.
