Azure IOT Edge message quota

问题


I have a problem with an Edge device that I have. Even though no devices are sending any data, the message quota is seeing a lot of traffic even though no messages are beeing sent. For example 14000 messages will be accumulated during 7 hrs or so.

Is there any way to debug the internal messages?

I've checked with docker logs edgeHub and docker logs edgeAgent but nothing out of the ordinary there.

If it can help someone, I had this kind of problem yesterday, sending message from my edge device with a Python test app and never find it on the cloud. I missed the async behaviour of the send_message function.

You should have something like :

# At the beginning of you code

# Create an IoT Hub client
client = IoTHubModuleClient.create_from_edge_environment()
# connect the client.
await client.connect()

# ... and in your main loop

# Send the message.
await client.send_message(message)

Your Python app should use asyncio. If you forgot await for send_message, your code will not produce errors but it just won't work.

If it works, you should see a bunch of azure sdk debug logs with a docker logs of your Python app, like :

About this :

Even though no devices are sending any data, the message quota is seeing a lot of traffic even though no messages are beeing sent

Take care of the bad interpretation of Total number of messages used. The real value you should look at is Telemetry messages sent
