Use case:
We are sending alert notification to multiple destinations. For some reason, we don't want to send notification to one destination any more.

I see the destination can be deleted on "Destinations" page. But if the destination is in usage, it can't be deleted and will pop up such warning "Couldn't delete destination dest1. One or more monitors uses this destination." As the message doesn't show which monitor is using the destination, I have to go through all of the triggers and delete the actions which are using the destination (currently, one action can only send notification to one destination, maybe we can enhance it to support multiple destinations in one action?).

Suggestions:
1.Show which monitor/trigger/action are using the destination
2.Just suspend one destination if the delete action is too heavy.

Start by tracing the Destinations page and how monitors, triggers, and actions reference destinations. Resolve whether the intended outcome is usage visibility or suspending a destination, then verify that the selected behavior lets users stop notifications without deleting an in-use destination.
