Event notification reference

  • Reference
  • 8-min read

These tables list the Managed Cluster events by category and show which of them send email under the notifications you set up in Configure event notifications.

In the Email notification column, Configurable means that you can turn the email notification for that event on or off through the Settings API, with the settings schema builtin:cluster-events-notification-settings. The API token needs the settings.read and settings.write scopes.
