Audit event streaming for instances, administrators can:

• Set a streaming destination for an entire instance to receive all audit events about that instance as structured JSON.
• Manage their audit logs in third-party systems. Any service that can receive structured JSON data can be used as the streaming destination.

Each streaming destination can have up to 20 custom HTTP headers included with each streamed event.

GitLab can stream a single event more than once to the same destination. Use the id key in the payload to deduplicate incoming data.

Audit events are sent using the POST request method protocol supported by HTTP.

WARNING: Streaming destinations receive all audit event data, which could include sensitive information. Make sure you trust the streaming destination.

Manage streaming destinations for an entire instance.

• Feature flag ff_external_audit_events enabled by default in GitLab 16.2.
• Instance streaming destinations made generally available in GitLab 16.4. Feature flag ff_external_audit_events removed.

Each streaming destination has a unique verification token (verificationToken) that can be used to verify the authenticity of the event. This token is either specified by the Owner or generated automatically when the event destination is created and cannot be changed.

Each streamed event contains the verification token in the X-Gitlab-Event-Streaming-Token HTTP header that can be verified against the destination's value when listing streaming destinations.

Prerequisites:

• Administrator access on the instance.

To list streaming destinations for an instance and see the verification tokens:

1. On the left sidebar, at the bottom, select Admin.
2. Select Monitoring > Audit events.
3. On the main area, select the Streams tab.
4. View the verification token on the right side of each item.

• Event type filtering in the UI with a defined list of audit event types introduced in GitLab 16.3.

When this feature is enabled, you can permit users to filter streamed audit events per destination. If the feature is enabled with no filters, the destination receives all audit events.

A streaming destination that has an event type filter set has a filtered ({filter}) label.

By default, streaming destinations use a content-type header of application/x-www-form-urlencoded. However, you might want to set the content-type header to something else. For example ,application/json.

To override the content-type header default value for an instance streaming destination, use either:

• The GitLab UI.
• The GraphQL API.
