Nagios Support Forum

Hi all,

I am a bit desperate here and I need help with one check command on Nagios XI. I will try my best to explain what is it that I can't get working.

I have a Nagios XI which monitors Windows servers with NSClient++ installed. I have a working service on one server that I would like to use on some other servers. It is a command defined in nsclient.ini that uses a powershell script.

When adding a new command to another server exactly as defined on first server on which that command works OK and copying the script I get some odd behaviour that I can't solve.

Command works OK from nagiosxi CLI, it returns expected results to command line, tried to run the check as root and as nagios user.
Command works OK from nagiosxi web ui from core config manager from defined service where there is a Run command button to check the service against a host you wish.
Command DOES NOT WORK OK from nagiosxi web ui after the service is created and configuration is applied. Service status is in UNKNOWN state with the output Unknown command(s): check_command_name

I am using check_nrpe from nagios server and NSClient++ on Windows server. Could someone point me in the right direction where to look, and how to troubleshoot this and make this to work. Thans in advance.

Can you show us the actual command, run from the command line, along with the output of it, and the service config?

CCM > Services > <your service> > View config

Desperately I went through configuration for that service on nagios server, nsclient++ configuration on the client server, and all looked good.

Then I found out why the service can't work, and it was about wrong host configuration. The IP address in host definition was wrong.

That explains why I was getting the expected results when testing, either from command line or web UI while service definition, beacause there I used dns name of the server. When the service was defined it was run against the wrong host.

I'm sorry for posting, it turned out to be a rookie mistake with host definition.

Glad you figured it out!
