# 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
|
|
}
|
|
}
|
|
```
|
|
|
|
### Delete with the API
|
|
|
|
Group owners can remove a HTTP header using the GraphQL `auditEventsStreamingHeadersDestroy` mutation.
|
|
|
|
```graphql
|
|
mutation {
|
|
auditEventsStreamingHeadersDestroy(input: { headerId: "gid://gitlab/AuditEvents::ExternalAuditEventDestination/24601" }) {
|
|
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).
