None of these messages are error messages, only debug messages.
What is missing from the output is Telegraf saying it collected any metrics from your input. Are you sure there are events coming into eventhub? That plugin works by connecting to eventhub, which it looks like it succeeded or it would have errored, and then waits for messages to appear and pull down.
I would check when your latest event is in eventhub and if possible try to send a test event.
If you you believe you are getting metrics from the inputs and not sent to the output, then I would suggest adding the [[outputs.file]] output and see if any metrics are printed out. That will print any metrics collected to STDOUT. However, based on your log messages this does not appear to be the case.
I still believe that your input configuration is not collecting any events. Try the above first to see if any events show up.
