Our azure event hub has been running for a few months now in a production environment. Today the event hub stopped receiving inputs and processing any outputs. Not sure what the problem is?
Our stream analytics also can't connect to the event hub anymore - also one of the stream jobs has a status of 'degraded'. Could this be the cause for the whole hub to go down?
Most likely the degraded status of your Stream Analytics job is caused by the Event Hub access issue. You can confirm this from the job's activity log.
