Dynatrace provides audit logs of all changes to your account-level identity and access (IAM) management settings, including:
Administrators can view these logs in Account Management > Settings > Audit log.
For more information about audit logs, see Audit logs on Grail.
To view Account Management audit logs you need the following permissions:
To view the Audit logs page, you need the account-company-info role.
To access audit logs via API, you need
account-audit-logs-read scope.account-company-info role.Each audit log contains all information about a specific configuration change. These could be caused by a UI interaction, an API call via Dynatrace Platform Subscription API, a system event, or a scheduled non-interactive task.
This includes, for example:
Timestamp: The time at which the request was processed. (All time references are based on the UTC+0 time zone.)
User: The user that made change.
(The DYNATRACE user indicates a change made by a Dynatrace employee or an internal system event.)
Event provider: The category of resource in which the change was made, such as IAM (Identity and account management).
Event type: A specific identifier from the area that specifies the change that is recorded in the audit log.
Resource: The identifier of the resource that is being audited.
Resource name: The name of the resource.
Examples of complete audit log entries are provided at Account Management audit log examples.

To run a query, select either Update or Refresh (depending on whether or not you've already run a query).
The table, visible in the middle of the page, presents the main information related to the request.

When you select a log entry, a pane opens at the bottom of the page to show the specific change that was made.
The Raw data pane, to the left of the diff-style view, contains the complete JSON contents of a given audit event.
