How to debug edgeHub module in Azure IoT Edge

is there anyway to trace the messaging flow in edgeHub? i have two modules that connect sensors (the opc-ua publisher) and a coap proxy and i am routing them to the cloud with
"all2hub": "FROM /messages/* INTO $upstream" That works fine and I can see the telemetry from both devices If i add another module that does nothing but writes to the console every message it receives with "all2test": "FROM /messages/* INTO BrokeredEndpoint(\"/modules/tester/inputs/test\")" I don't get a single message coming to the test module...I wonder if I could trace and see what is happening....

You can enable debug logs for edgeHub by adding RuntimeLogLevel environment variable with value debug to the deployment (from the portal go to Set modules -> Configured advanced Edge runtime settings)

Another way to enable debug logs is by updating the IoT Edge security manager config file

Replace env: {} with 

env:
  RuntimeLogLevel: debug

Save the file and restart the IoT Edge security manager.

With debug logs enavled you should check edgeHub logs if messages are received and sent.
