问题
I tried to set offset 3 and 0, all works fine with statistics with REST setup for now. However, the DAS wso2carbon.log keeps throwing the following error messages:
TID: [-1] [] [2016-09-15 16:27:30,727] ERROR {org.wso2.carbon.databridge.agent.endpoint.DataEndpointConnectionWorker} -

I am wondering what caused this, and how to fix it?
回答1:
What I did is to remove port 7711 from data receiver config in apim admin-dashabord/Analytics. It is now only list tcp://localhost:7611 . That seems to fix it, but don't know why it did not respond at 7711 as it is actually configured in DAS conf/data-bridge/data-bridge-config.xml.
回答2:
If you have installed any car files, you may need to update the port of receiver URL in scripts inside them, to match with your offset.
