title: What are outgoing messages in Service Bus?
body: <p>I need help interpreting this graph:
  <a href="https://i.stack.imgur.com/o0lhD.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/o0lhD.png" alt="enter image description here" /></a>
  It looks like messages are coming in, then being processed, and going back to 0. The graph is not continually rising.</p>
  <p>However, the outgoing messages has &quot;--&quot;. Does this mean 0?</p>
  <p><strong>Does an outgoing message represent a message being read by a service?</strong></p>
  <p>If the messages are not being read, then what is happening to them? The dead letter queue has 0 messages.</p>
