@ryan-carroll-graylog The code changes here look good to me and test successfully.

One aside: I noticed that the adapter is not flagged as no longer working in the frontend with that alert icon.

The details page does show it's not working though:

I think removed inputs have a way that they show an error state that the input class is no longer available at the top-level. It would be helpful to users if something similar were supported for adapters at the top level list, maybe showing that same alert icon as is done when CSV files are no longer available. What do you think about creating a separate task for that and maybe we can look into it separately?

Ah great point, yeah I think something similar to inputs to notify users that the adapter won't work makes sense. Opening an issue for it now.
