From the description and screen shot, it would appear that this agent is installed on a host that might be a secondary node and not detecting any database process running.
I see that the server group and default service are assigned.
if this host is a secondary node, then you could add a user defined interface until the node become active, which should then pick up the data interfaces, if this is a primary node and you have database services running on the host, suggest open a case, so that tech support can examine log files.
it's either what Trevor touched on, or it is a RAC on Windows, in which case Data Interface Discovery is not supported so you'll have to add your Data Interfaces manually.
