We have a Docker registry running on 3.1 and various users are allowed to push images to the registry. In order to push they all have to login to the respective registry on NXRM. Currently we can not find a way to determine which users pushed which image. There are numerous attributes like last accessed and others, but none that indicates who created the image.
In NXRM 2 this info is shown for Maven artifacts and it would be great to see that for all components and assets in v3.
