I believe the table you are looking at , i.e- NmsTrackingLogRtEvent Should be blank if it's a control instance. This table is populated only on a RT server (Message centre) and in the Control side the table nms:trackingLogEventHisto should be populated.
This is updated by a Mc_sync workflow and not the usual tracking workflow. In the newer version of 6.1.1 there is a new version of the sync workflow that works. Can you check if this is also running fine and then check the data in nms:trackingLogEventHisto
