Report performance and availability in PBI Premium cloud

If you are using premium capacity, you could install the Premium Capacity Metrics app to gain insights into performance of your capacity

Also, in the Power BI admin portal, in the tenant settings, you can configure the "
Receive email notifications for service outages or incidents" setting, but not sure when this gets fired off

I also believe with the announcement below, there may be other things to monitor or be notified about, though it is not clear to me yet as to the specifics
