Audit repository events

Starting in DTR 2.6, each repository page includes an Activity tab which displays a sortable and paginated list of the most recent events within the repository. This offers better visibility along with the ability to audit events. Event types listed vary according to your repository permission level. Additionally, MSR admins can enable auto-deletion of repository events as part of maintenance and cleanup.

In the following section, we will show you how to view and audit the list of events in a repository. We will also cover the event types associated with your permission level.

View List of Events

As of DTR 2.3, admins were able to view a list of MSR events using the API. MSR 2.6 enhances that feature by showing a permission-based events list for each repository page on the web interface. To view the list of events within a repository, do the following:

  1. Navigate to https://<msr-url> and log in with your MSR credentials.

  2. Select Repositories from the left-side navigation panel, and then click on the name of the repository that you want to view. Note that you will have to click on the repository name following the / after the specific namespace for your repository.

  3. Select the Activity tab. You should see a paginated list of the latest events based on your repository permission level. By default, Activity shows the latest 10 events and excludes pull events, which are only visible to repository and MSR admins.

    • If you’re a repository or a MSR admin, uncheck Exclude pull to view pull events. This should give you a better understanding of who is consuming your images.

    • To update your event view, select a different time filter from the drop-down list.

Activity Stream

The following table breaks down the data included in an event and uses the highlighted Create Promotion Policy event as an example.

Event detail




Friendly name of the event.

Create Promotion Policy


This will always be the repository in review following the <user-or-org>/<repository_name> convention outlined in Create a repository



Tag affected by the event, when applicable.

test-org/test-repo-1:latest where latest is the affected tag


The digest value for ``CREATE` operations such as creating a new image tag or a promotion policy.



Event type. Possible values are: CREATE, GET, UPDATE, DELETE, SEND, FAIL and SCAN.


Initiated by

The actor responsible for the event. For user-initiated events, this will reflect the user ID and link to that user’s profile. For image events triggered by a policy – pruning, pull / push mirroring, or promotion – this will reflect the relevant policy ID except for manual promotions where it reflects PROMOTION MANUAL_P, and link to the relevant policy page. Other event actors may not include a link.


Date and Time

When the event happened in your configured time zone.

Event Audits

Given the level of detail on each event, it should be easy for MSR and security admins to determine what events have taken place inside of MSR. For example, when an image which shouldn’t have been deleted ends up getting deleted, the security admin can determine when and who initiated the deletion.
