See the state of your entire Sentinel-based cluster including which nodes are serving which roles and and real-time stream of Sentinel updates.
Need to restart a host for patching? Want a master to relinquish its duties for any other reason? Start a failover to promote a slave at any time.
Adding additional nodes to improve reliability is easy. Just choose the desired Sentinel and select a node to add! It will now be a candidate for failover if the master fails.
Easily create entirely new Sentinel configurations. Set the quorum, and choose a few nodes to add and you're done.
Change the rules that Sentinel follows when it monitors your nodes. Set the failover timeout and other key variables.
