Nagios Support Forum

I installed NagiosXi on my Centos AWS instance to monitor another host (AWS instance running Amazon Linux, however I get "(No output on stdout) stderr: Traceback (most recent call last):" for most of the services, I'm not sure how to fix it.

Can you show us one of the failing checks run from the command line along with the output of it? Please add "-v" to the check for increased verbosity.
