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?

https://docs.microsoft.com/en-us/azure/azure-monitor/platform/alerts-activity-log-service-notifications?toc=%2fazure%2fservice-health%2ftoc.json 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.
