"Failed Exception : Connection failure" while trying to add WebLogic monitor
- Check whether the WebLogic host and port is accessible via TELNET.
- Check if you have used the configured listener address while trying to add the monitor.
- Listener can be obtained under Environment -> Servers -> <myserver> -> Configuration -> General -> Listen Address field
- Check whether there is any firewall between WebLogic Host and the Applications Manager machine. If this is the case, then open WebLogic host and port in the Applications Manager side.
- Check whether Filters are enabled in Weblogic domain, and Applications Manager Host/IP is restricted.
- <mydomain> -> Security -> Filter
- Check whether the Hostname / IP address of WebLogic machine is resolvable from Applications Manager machine. The Hostname / IP address can be resolved by executing the nslookup command.
- Check whether the /etc/resolv.conf file (in windows it is Windows\System 32\drivers\etc\hosts file) in the Applications Manager Machine has correct domain.
- Enable T3 Tunneling by following the steps mentioned here.
