When I try to monitor a WebLogic server, I get an "Unknown host name" message.
There are two possible reasons for this message:
- Hostname is not resolving properly.
To monitor WebLogic server, the hostname should be resolving properly in the Applications Manager host. If the host is not resolving, specify the correct entry in the ‘etc/hosts’ file of Applications Manager. - The listen address not specified correctly in the WebLogic console.
Check if the Listen Address is correctly provided in the WebLogic server. You can check the Listen Address from the below path:
The Listen Address field should have the correct WebLogic host name/IP address.Environment -> Servers -> <myserver> -> Configuration -> General -> Listen Address field
