Hi,
Service Health alerts are basically Activity Log Alerts. These alerts can be configured at subscription level at most. This means you will have to configure such alert for each subscription no matter at which tenant is located. If you want to consolidate the notification for those alerts I would suggest to use some ITSM tool where you log a ticket for those alerts. You can create your own custom logic via some automation service like Azure Functions, Azure Logic App, Azure Automation, etc. where incident with trackingId value already exists you do not open a new ticket but rather update the existing one. trackingId is available in common alert schema for those types of alerts. The trackingId will have the same value for a service health issue no matter which tenant/subscription affects.
