Use redis-cli with port 26379 to connect to sentinel.
Note: you always want to tail the /var/log/sentinel/sentinel.log
on all sentinels to see the cluster interaction.
redis-cli -p 26379
List masters for all managed clusters:
127.0.0.1:26379> sentinel masters # to get all masters (or if you don't know the cluster name)
127.0.0.1:26379> sentinel master <cluster-id> # get current sentinel master
127.0.0.1:26379> sentinel get-master-addr-by-name <cluster-id> # get current sentinel master IP
Determine slaves for one cluster
sentinel slaves <cluster-id>
Force failover
sentinel failover <cluster-id>
