In this scenario lets imagine we've created a Policy with a Watch. The Policy was then linked to a Global Collection.
Then a rule change for the Global Collections membership was made in error. The bad query triggered the addition of many unwanted models to the collections membership.
The models were removed from the collection membership but the Watch and its related alarm remain applied to them. How can we delete them?
A policy was created to enable an uptime watch on a limited global collection. When a logical mistake was made in that GC's search parameters, the Watch was applied to all models in the environment.
Select a model that has the Watch applied to it. Delete the Watch for this one model.
This deletion activity triggers deletion of the Watch from ALL models it is tied to globally.
The Watch will need to then be reapplied to the models it belongs with.
