Audit event streaming

Users can set a streaming destination for a top-level group to receive all audit events about the group, its subgroups, and projects as structured JSON.

Top-level group owners can 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.

Add a new streaming destination

Use the GitLab UI

Users with the Owner role for a group can add streaming destinations for it:

1. On the top bar, select Main menu > Groups and find your group.
2. On the left sidebar, select Security and Compliance > Audit events.
3. On the main area, select Streams tab.
4. Select Add streaming destination to show the section for adding destinations.
5. Enter the destination URL to add.
6. Optional. Locate the Custom HTTP headers table.
7. Ignore the Active checkbox because it isn’t functional. To track progress on adding functionality to the Active checkbox, see issue 367509.
8. Select Add header to create a new name and value pair. Enter as many name and value pairs as required. You can add up to 20 headers per streaming destination.
9. After all headers have been filled out, select Add to add the new streaming destination.

Use the API

To enable streaming and add a destination, users with the Owner role for a group must use the externalAuditEventDestinationCreate mutation in the GraphQL API.

mutation {
  externalAuditEventDestinationCreate(input: { destinationUrl: "https://mydomain.io/endpoint/ingest", groupPath: "my-group" } ) {
    errors
    externalAuditEventDestination {
      id
      destinationUrl
      verificationToken
      group {
        name
      }
    }
  }
}

Group owners can also optionally specify their own verification token (instead of the default GitLab-generated one) using the GraphQL auditEventsStreamingHeadersCreate mutation. Verification token length must be within 16 to 24 characters and trailing whitespace are not trimmed. GitLab recommends setting a cryptographically random and unique value. For example:

mutation {
  externalAuditEventDestinationCreate(input: { destinationUrl: "https://mydomain.io/endpoint/ingest", groupPath: "my-group", verificationToken: "unique-random-verification-token-here" } ) {
    errors
    externalAuditEventDestination {
      id
      destinationUrl
      verificationToken
      group {
        name
      }
    }
  }
}

Event streaming is enabled if:

• The returned errors object is empty.
• The API responds with 200 OK.

Group owners can add an HTTP header using the GraphQL auditEventsStreamingHeadersCreate mutation. You can retrieve the destination ID by listing all the streaming destinations for the group or from the mutation above.

mutation {
  auditEventsStreamingHeadersCreate(input: { destinationId: "gid://gitlab/AuditEvents::ExternalAuditEventDestination/24601", key: "foo", value: "bar" }) {
    errors
  }
}

The header is created if the returned errors object is empty.

List streaming destinations

Users with the Owner role for a group can list streaming destinations.

Use the GitLab UI

To list the streaming destinations:

1. On the top bar, select Main menu > Groups and find your group.
2. On the left sidebar, select Security and Compliance > Audit events.
3. On the main area, select Streams tab.
4. To the right of the item, select Edit () to see all the custom HTTP headers.

Use the API

Users with the Owner role for a group can view a list of streaming destinations at any time using the externalAuditEventDestinations query type.

query {
  group(fullPath: "my-group") {
    id
    externalAuditEventDestinations {
      nodes {
        destinationUrl
        verificationToken
        id
        headers {
          nodes {
            key
            value
            id
          }
        }
        eventTypeFilters
      }
    }
  }
}

If the resulting list is empty, then audit streaming is not enabled for that group.

You need the ID values returned by this query for the update and delete mutations.

Update streaming destinations

Users with the Owner role for a group can update streaming destinations.

Use the GitLab UI

To update a streaming destinations custom HTTP headers:

1. On the top bar, select Main menu > Groups and find your group.
2. On the left sidebar, select Security and Compliance > Audit events.
3. On the main area, select Streams tab.
4. To the right of the item, select Edit ().
5. Locate the Custom HTTP headers table.
6. Locate the header that you wish to update.
7. Ignore the Active checkbox because it isn’t functional. To track progress on adding functionality to the Active checkbox, see issue 367509.
8. Select Add header to create a new name and value pair. Enter as many name and value pairs as required. You can add up to 20 headers per streaming destination.
9. Select Save to update the streaming destination.

Use the API

Users with the Owner role for a group can update streaming destinations custom HTTP headers using the auditEventsStreamingHeadersUpdate mutation type. You can retrieve the custom HTTP headers ID by listing all the custom HTTP headers for the group.

mutation {
  externalAuditEventDestinationDestroy(input: { id: destination }) {
    errors
  }
}

Streaming destination is updated if:

• The returned errors object is empty.
• The API responds with 200 OK.

Group owners can remove an HTTP header using the GraphQL auditEventsStreamingHeadersDestroy mutation. You can retrieve the header ID by listing all the custom HTTP headers for the group.

mutation {
  auditEventsStreamingHeadersDestroy(input: { headerId: "gid://gitlab/AuditEvents::Streaming::Header/1" }) {
    errors
  }
}

The header is deleted if the returned errors object is empty.

Delete streaming destinations

Users with the Owner role for a group can delete streaming destinations.

When the last destination is successfully deleted, streaming is disabled for the group.

Use the GitLab UI

To delete a streaming destination:

1. On the top bar, select Main menu > Groups and find your group.
2. On the left sidebar, select Security and Compliance > Audit events.
3. On the main area, select the Streams tab.
4. To the right of the item, select Delete ().

To delete only the custom HTTP headers for a streaming destination:

1. On the top bar, select Main menu > Groups and find your group.
2. On the left sidebar, select Security and Compliance > Audit events.
3. On the main area, select the Streams tab.
4. To the right of the item, Edit ().
5. Locate the Custom HTTP headers table.
6. Locate the header that you wish to remove.
7. To the right of the header, select Delete ().
8. Select Save to update the streaming destination.

Use the API

Users with the Owner role for a group can delete streaming destinations using the externalAuditEventDestinationDestroy mutation type. You can retrieve the destinations ID by listing all the streaming destinations for the group.

mutation {
  externalAuditEventDestinationDestroy(input: { id: destination }) {
    errors
  }
}

Streaming destination is deleted if:

• The returned errors object is empty.
• The API responds with 200 OK.

Group owners can remove an HTTP header using the GraphQL auditEventsStreamingHeadersDestroy mutation. You can retrieve the header ID by listing all the custom HTTP headers for the group.

mutation {
  auditEventsStreamingHeadersDestroy(input: { headerId: "gid://gitlab/AuditEvents::Streaming::Header/1" }) {
    errors
  }
}

The header is deleted if the returned errors object is empty.

Verify event authenticity

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.

Use the GitLab UI

Users with the Owner role for a group can list streaming destinations and see the verification tokens:

1. On the top bar, select Main menu > Groups and find your group.
2. On the left sidebar, select Security and Compliance > Audit events.
3. On the main area, select the Streams.
4. View the verification token on the right side of each item.

Event type filters

When this feature is enabled for a group, you can use an API to 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 () label.

Use the API to add an event type filter

Prerequisites:

• You must have the Owner role for the group.

You can add a list of event type filters using the auditEventsStreamingDestinationEventsAdd query type:

mutation {
    auditEventsStreamingDestinationEventsAdd(input: {
        destinationId: "gid://gitlab/AuditEvents::ExternalAuditEventDestination/1",
        eventTypeFilters: ["list of event type filters"]}){
        errors
        eventTypeFilters
    }
}

Event type filters are added if:

• The returned errors object is empty.
• The API responds with 200 OK.

Use the API to remove an event type filter

Prerequisites:

• You must have the Owner role for the group.

You can remove a list of event type filters using the auditEventsStreamingDestinationEventsRemove query type:

mutation {
    auditEventsStreamingDestinationEventsRemove(input: {
    destinationId: "gid://gitlab/AuditEvents::ExternalAuditEventDestination/1",
    eventTypeFilters: ["list of event type filters"]
  }){
    errors
  }
}

Event type filters are removed if:

• The returned errors object is empty.
• The API responds with 200 OK.
