Sending one message to IoT hub and IoT hub metrics says 16 RRS feed

  • Question

  • Dear, 

    I am sending with an ESP32 messages to the IoTHub. I am sending a JSON within it an array of 100 elements which is then parsed with the stream analytics to a sql database. When I send just one JSON to the IoT hub, this is saying that 17 messages where sent... My message is 25 kB big. Do you guys know why it is like that?

  • hi

    you could open a support ticket in your Azure Portal

    basically its related to message counting

    for example device to cloud messages are charged in 4KB chunks on ingress into IoT Hub, additionally you have stream analytics and a sql database …

    so for IoT Hub 25 / 4 = 7 messages, not sure about stream analytics and sql database costs

    Azure IoT Hub pricing information
