Cluster Event Log

The cluster event log displays important cluster life cycle events that you trigger manually or are automatically triggered by Azure Databricks. Such events affect the operation of a cluster as a whole and the jobs running in the cluster.

The following event types are available:

  • CREATING
  • STARTING
  • RESTARTING
  • TERMINATING
  • EDITED
  • RUNNING
  • RESIZING - includes manual resizing and automatic resizing by auto-scaling.
  • NODES_LOST - includes when a worker is terminated by the cloud provider (for example, spot instance termination, maintenance, and so on).

Events are stored for 60 days, which is comparable with other data retention times in Databricks.
