After looking closer at the interface being used to listen for Oracle traffic, it was found the interface was configured with an IPv6 address. Currently, the agent will only discover and listen for traffic on interfaces with an IPv6 address.
As soon as the interface was configured with an IPv4 address and Oracle was configured to listen on that interface suing the IPv4 address, audit and event data was captured by the agent and reported on. If you suspect this be an issue in your situation you can follow these steps to narrow down the problem. This is an example for a non-Windows server, but the principle would be the same for a Windows server:
NOTE: Only part of the IPv6 address is displayed by netstat so you need to search on the first octets only. If it appears this is the issue then work with the Oracle DBA and assign an IPv4 address.Have you run into this situation before?
