Azure Service Health - minimum privileges

In Azure Service Health some of our Global Administrators are getting "No permissions to read Service Health events for 1 subscription(s)" messages. What are the minimum roles or privileges needed in a subscription to allow Azure Service Health (and alerts) to function?

Create activity log alerts on service notifications and related articles do not seem to address the issue we are trying to address. 

We would like to be able to have non-Global Admin accounts, like tier 1 support, to see Azure Service Health, but first just knowing how to make it function as expected would be good.
