The Cluster Event Log provides detailed information about various events affecting the cluster throughout its lifecycle, including cluster creation, restarts, termination, and resizing events. It displays the timestamp, event type (e.g., "CLUSTER_RESIZED"), and relevant details for each event, allowing the administrator to review the timeline for cluster scaling behavior and identify potential patterns related to user activity or resource-intensive queries.

The timeline for cluster resizing events can be reviewed in the Cluster Event Log. This log provides information about cluster scaling events, including when the cluster is scaled up or down. You can access this information to understand the reasons behind autoscaling events and whether they are triggered by many concurrent users or resource-intensive queries.
