# Audit event streaming **(ULTIMATE)**

> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/332747) in GitLab 14.5 [with a flag](../administration/feature_flags.md) named `ff_external_audit_events_namespace`. Disabled by default.
> - [Enabled on GitLab.com and by default on self-managed](https://gitlab.com/gitlab-org/gitlab/-/issues/338939) in GitLab 14.7.
> - [Feature flag `ff_external_audit_events_namespace`](https://gitlab.com/gitlab-org/gitlab/-/issues/349588) removed in GitLab 14.8.

Users can set an HTTP endpoint 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 endpoint.

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

## Add a new event streaming destination

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

### Use the GitLab UI

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

1. On the top bar, select **Menu > Groups** and find your group.
1. On the left sidebar, select **Security & Compliance > Audit events**
1. On the main area, select **Streams** tab.
    - When the destination list is empty, select **Add stream** activate edit mode and add a new destination.
    - When the destination list is not empty, select **{plus}** under the **Streams** tab to activate edit mode.
1. Enter the endpoint you wish to add and select **Add**.

Event streaming is enabled if:

- No warning is shown.
- The added endpoint is displayed in the UI.

### Use the API

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

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

Event streaming is enabled if:

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

## List streaming destinations

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

### Use the GitLab UI

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/336411) in GitLab 14.9.

Users with at least the Owner role for a group can list event streaming destinations:

1. On the top bar, select **Menu > Groups** and find your group.
1. On the left sidebar, select **Security & Compliance > Audit events**
1. On the main area, select **Streams** tab.

### Use the API

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

```graphql
query {
  group(fullPath: "my-group") {
    id
    externalAuditEventDestinations {
      nodes {
        destinationUrl
        verificationToken
        id
      }
    }
  }
}
```

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

## Delete streaming destinations

Users with at least the Owner role for a group can delete event streaming destinations using the
`deleteAuditEventDestinations` mutation type.

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

### Use the GitLab UI

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/336411) in GitLab 14.9.

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

1. On the top bar, select **Menu > Groups** and find your group.
1. On the left sidebar, select **Security & Compliance > Audit events**
1. On the main area, select **Streams** tab.
1. Select **{remove}** at the right side of each item.

The external streaming destination is deleted when:

- No warning is shown.
- The deleted endpoint is not displayed in the UI.

### Use the API

Delete an event streaming destination by specifying an ID. Get the required ID by
[listing the details](audit_event_streaming.md#use-the-api-1) of event
streaming destinations.

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

Destination is deleted if:

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

## Custom HTTP header values

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/361216) in GitLab 15.1 [with a flag](feature_flags.md) named `streaming_audit_event_headers`. Disabled by default.

FLAG:
On self-managed GitLab, by default this feature is not available. To make it available per group, ask an administrator to [enable the feature flag](../administration/feature_flags.md) named `streaming_audit_event_headers`.
On GitLab.com, this feature is not available.
The feature is not ready for production use.

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

### Add with the API

Group owners can add a HTTP header using the GraphQL `auditEventsStreamingHeadersCreate` mutation.

```graphql
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.

## Verify event authenticity

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/345424) in GitLab 14.8.

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

Each streamed event contains a random alphanumeric identifier for the `X-Gitlab-Event-Streaming-Token` HTTP header that can be verified against
the destination's value when [listing streaming destinations](#list-streaming-destinations).

## Audit event streaming on Git operations

> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/332747) in GitLab 14.9 [with a flag](../administration/feature_flags.md) named `audit_event_streaming_git_operations`. Disabled by default.
> - [Enabled on GitLab.com](https://gitlab.com/gitlab-org/gitlab/-/issues/357211) in GitLab 15.0.
> - [Enabled on self-managed](https://gitlab.com/gitlab-org/gitlab/-/issues/357211) in GitLab 15.1 by default.

FLAG:
On self-managed GitLab, by default this feature is available. To hide the
feature, ask an administrator to [disable the feature flag](feature_flags.md) named `audit_event_streaming_git_operations`.

Streaming audit events can be sent when signed-in users push or pull a project's remote Git repositories:

- [Using SSH](../user/ssh.md).
- Using HTTP or HTTPS.
- Using the **Download** button (**{download}**) in GitLab UI.

Audit events are not captured for users that are not signed in. For example, when downloading a public project.

To configure streaming audit events for Git operations, see [Add a new event streaming destination](#add-a-new-event-streaming-destination).
