title: How do you monitor Azure Event Hub consumer lag?
body: <p>We have been trying monitor consumer lag on Event Hub partitions. </p>
  
  <p>I have looked in the azure portal and the Event Hub Api's but so far found nothing. </p>
  
  <p>Was wondering if anyone has tried this and if so could you point me in the right direction. </p>
  
  <p>Thanks. </p>
