Info

The table to the right shows the current status of a cluster of three Event Store appliances running in a high availability configuration, and connected to a set of remotely controlled power sockets.

A test suite is running that constantly reads and writes events to the cluster, you can see the current performance in the Client Activity graph.

To verify that the cluster behaves correctly during a node failure, we have a seperate process which repeatedly kills and restores power to a random node.

If the node to which the client is currently connected to is killed you should see debug text in the console confirming that the client has chosen another server and switched over automatically.
