I am using Azure's service bus (topics/subscriptions specifically) to send messages back and forth. Seemingly at random, when sending a message to the topic, the message seems to be disappearing and no errors are thrown. If I look at the chart in the Azure management portal for the topic, I can see a portion of messages are failing.
2 questions:
1 - Where is documentation on what can cause a request to fail?
2 - How do I log these requests so I can see the error?
