Hi @Vishwanath Hariharan Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.
One of the possible reasons why you might be receiving data could be the usage of the same
Consumer group. IoT Hub allows you to add consumer groups for endpoints to provide independent views into the event stream that enable apps and Azure services to independently consume data from the same Event Hub endpoint. It is recommended that there's only one active receiver on a partition within a consumer group. Inspect your Azure Stream Analytics input section to see if the Consumer Group is set to
$Default Please refer the below image for reference.
Add a new Consumer Group on your IoT Hub and set it to the Stream Analytics job consumer group. Wait a few minutes and see if the events start.
Another reason why the Stream analytics job might be failing could be due to multiple parallel jobs running on Stream Analytics cluster. This might be the reason why the
Watermark delay keeps increasing. If you suspect this could be the cause, please refer the article Analyze Stream Analytics job performance by using metrics and dimensions for debugging steps on how to overcome this issue.
