I think I'm missing something.
Alerts only used to show something that required an action or attention from someone that could administer that request.
Does it now show things that succeed and fail?
I think only showing an Error when an Error occurred is good but I want to make sure that your request is not saying "hey I don't like alerts so I don't want to see them" at all.
In that I think I would modify your request to say make the Alerting system customizable for the user experience. Allow the user to set whether they see events for specific items.
