When you first start a probe, you should see something like this in the WrapperProbeGw.log:

jvm 1 | <2024-08-19 06:34:42,790> 33475 [INFO ] [Thread-50] (HostKeyUtil.java:704) - Attempting to get complete local host via WMI
jvm 1 | <2024-08-19 06:34:42,830> 33515 [INFO ] [Thread-50] (CloudUtil.java:40) - This is not a cloud probe, so not set cloud instance id to node.
jvm 1 | <2024-08-19 06:34:42,831> 33516 [INFO ] [Thread-50] (HostKeyUtil.java:706) - Got complete local host via WMI successfully

This is how the probe gets its IP Address.  Next you will see some message about the Probe Manager Topology being sent to the UCMDB Server.

This vector will have the IP Address that should be on the UCMDB Server.  If it doesn't there may be some issue getting the IP from the probe server (e.g. permissions of the process running the probe aren't allowed to read the IP Address).  If it does, then it will be inserted into UCMDB and you can check the cmdb.reconciliation.audit.log to see that IP Address either being ignored or rejected due to some reconciliation issue.

That is the start of the checking.  FYI, the IP addresses in
