Which process monitors components, detects failures, and manages failover?

The Cluster Controller plays a crucial role in a Tableau Server environment by monitoring various components of the server. Its primary responsibility is to oversee the health of worker nodes within a cluster, ensuring that each component is functioning optimally. If any component encounters a failure, the Cluster Controller detects this issue and manages the failover process, which involves rerouting tasks to functioning nodes to maintain continuity and minimize disruption.

This functionality is essential for maintaining the performance and reliability of the Tableau environment, particularly in situations where high availability is necessary. By effectively managing these failover processes, the Cluster Controller helps ensure that users experience minimal downtime and that the system remains responsive even in the event of component failures. Thus, its monitoring capabilities and management of failover processes make it a vital component of the Tableau Server architecture.
