Calendar log events

Audit and investigation page: View and track changes to user events in Google Calendar
The audit log page has been replaced with a new audit and investigation page. For information about this change, go to Improved audit and investigation experience: What's new in Google Workspace

You can use the audit and investigation page to run searches related to Calendar log events. There you can view a record of actions to track changes to calendars, events, and subscriptions. You can also track the email notifications associated with these actions. This information is helpful when you troubleshoot issues or when your users notice discrepancies or unexpected changes to their calendars, shared calendars, or specific calendar events. Log entries usually appear within one half-hour of the user action.

For a full list of services and activities that you can investigate, such as Google Drive or user activity, read through the data sources for the audit and investigation page.
