Where can one review the timeline for cluster resizing events in Databricks?

The timeline for cluster resizing events in Databricks can be reviewed in the Cluster Event Log. This log captures detailed events related to the lifecycle of clusters, including actions such as resizing, starting, stopping, and termination of clusters. Each event is timestamped, providing a clear chronological history of changes that have occurred to the cluster, which is crucial for monitoring performance and troubleshooting any issues related to resource management.

The other options provide different types of information that may not encompass the detailed timeline of resizing events. For example, workspace audit logs primarily focus on user actions and permissions changes within the workspace environment. The driver's log file contains logs specific to the execution of jobs on that driver node, which does not specifically target cluster resizing events. Ganglia, while effective for monitoring cluster performance metrics, does not maintain a granular event log for resizing actions. Thus, the Cluster Event Log is the most appropriate resource for tracking and reviewing cluster resizing events in Databricks.
