The following chapters describe the relevant configurations of MashZone NextGen Dashboard in a clustered scenario.
From MashZone NextGen 10.2 on, Event Service can be run in clustered high-availability mode. There is no distinction between MashZone NextGen master and slave servers anymore. This means, to achieve high availability, you can now deploy multiple instances of Event Service to form a cluster. Cluster management is implemented using Apache Zookeeper.
Each MashZone NextGen server may connect to an arbitrary Event Service instance in the cluster and receive data from it. In case of an Event Service node failure, MashZone NextGen will automatically and transparently fail over to another alive node. When an Event Service node re-joins the cluster after a node failure, it will restore its state from Event Service' internal HA-Store.
