title: Should Redis Sentinel Monitor Each Master in a cluster?
body: <p>Does it require sentinel to monitor each master in the cluster with a distinct service name, or just one of the 3 masters in the cluster?</p>
  
  <p>My current config is 3 masters, 3 slaves, and 3 sentinel instances. Each instance of sentinel is monitoring each master. master1, master2, master3. I haven't seen any documentation that has more than a single master, and the redis documentation isn't real clear. </p>
