Clients not showing up on master. No errors encoutnered. New deployment

Icinga 2
1

Hi community

I am a noob with Icinga so I am sure I am missing something. The installation of the master, and client was flawless. I received no errors, as I wsas able to follow the debaian steps for deployment using your documetnations here Installation - Icinga 2

I am trying a very simple setup in a lab. Basically one master, adn one client. I have completed the node wizard to setup the master, and the node wizard to setup the client. Once completed and all services are restarted I do not get the new client in the icinga web 2. I don’t even get any errors or warnings in the log files whenever I restart the client. Any help here would be much appreciated, as I have now eliminated all errors, and have no clue where to go from here.

I also have full communications between the two hosts, I have been able to telnet on port 5665 in both directions.

Hi @techninja80

It looks like you created the zones and endpoints correctly, but you didn’t create a host object for the new client/agent. This doc entry may help.

Kind regards

Thanks, mate. You were spot on. The host is up and alive, thank you for putting me in the right direction. Again many thanks.
