You can track changes to calendars, events, and subscriptions in your Google Calendar audit log. You can also track the email notifications associated with these actions in the audit log. 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.
From the Admin console Home page, go to Reports.
- On the left, under Audit, click Calendar.
(Optional) To customize what you review, on the right, click Manage columns , select the columns that you want to see or hide, and click Save.

At Add a filter, select an Activity name to filter data for that event. The audit report will show log entries for each time that event occurred during the time range that you set. The event names are self-explanatory. For example, if you select Calendar created, your report will show a log entry for each time a user created a calendar.
