    Abstract: A method of dynamic cluster manager failover includes routing data traffic associated with managing a plurality of indexers in a cluster to a first cluster manager, wherein the first cluster manager is associated with an active role and is operable to manage the plurality of indexers in the cluster. The method also includes transmitting periodic heartbeat request messages from a second cluster manager of the cluster to the first cluster manager, wherein the second cluster manager is associated with a standby role. Further, the method includes detecting, at the second cluster manager, a loss of heartbeat response messages from the first cluster manager. Also, the method includes receiving information from a set of indexers regarding a status of the first cluster manager and in response to a determination that the status of the first cluster manager is offline, promoting the second cluster manager to switch over to the active role.

    Abstract: A computer-implemented method of providing for dynamic cluster manager failover includes routing data traffic associated with managing network components in a cluster to an active cluster manager, where the active cluster manager manages a plurality of network components in the cluster. The method also includes transmitting periodic heartbeat request messages from a standby cluster manager to the active cluster manager. Further, the method includes detecting a loss of heartbeat response messages from the active cluster manager, where the heartbeat response messages are transmitted from the standby cluster manager to the active cluster manager in response to the periodic heartbeat request messages. The method also includes promoting the standby cluster manager to an active role and re-routing the data traffic associated with managing the network components to the currently active cluster manager.
