On the Administration Events page it lists the admin events that have issues, most of these events (in our case) are related to Image Scanning. For instance, if an image is removed from our repo and not removed from a deployment, we will have 404 errors.

The fix for this is to either delete the deployment file or update the image.
This in turn will clean up the event.
However, it is almost impossible for us to track down which deployment or otherwise its related to.

Having extra metadata included on where it is getting the image from would greatly help us tracing these back to the source and be able to remediate. The metadata should include: "Cluster name, Namespace, Deployment".
