title: Connected_Slaves Metric When Using Slave of Slave in Redis
body: <p>When using the replication features of Redis in an environment with slaves of slaves, would the <code>connected_slaves</code> counter increase for the master, the slave which is acting as a master, or both? Refer to the example diagram: <a href="https://imgur.com/Ge1WLzX" rel="nofollow">https://imgur.com/Ge1WLzX</a></p>
  
  <p>In the image, there is a master with two slaves, each slave having its own two slaves. In this instance would the master's <code>connected_slaves</code> value be 6? Would the <code>connected_slaves</code> value of the first pair of slaves be 2 each?</p>
  
  <p>I have looked through Redis's documentation and have found nothing describing this.</p>
