Document commands for verifying and monitoring Redis with Redis sentinel in an HA cluster
Add to Redis HA docs how to access sentinel for monitoring purposes. https://redis.io/topics/sentinel#asking-sentinel-about-the-state-of-a-master
Already confirmed with Ian that the commands (also ran the commands on my test cluster) linked to above are available in Omnibus albeit undocumented. The idea is to be able to provide a simple way for administrators to confirm that Redis is setup and working correctly in an HA cluster.
At the moment, if redis isn’t working you get 500 errors although nothing really points to redis as the culprit. So if you aren’t getting 500s, redis is working. But if you are, it could be redis, or maybe something else
