Alert or monitoring for Traffic Manager service going down?

Hey everyone,

I was wondering if there was way to be alerted or to monitor when a component of the Traffic Manager service fails.
I know Traffic Manager is resilient to Azure region failures, as described here:
https://video2.skills-academy.com/en-us/azure/traffic-manager/traffic-manager-faqs

"In the unlikely event of an outage of an entire Azure region, Traffic Manager is expected to continue to function normally. Applications deployed in multiple Azure regions can rely on Traffic Manager to direct traffic to an available instance of their application."

However it seems to have a contradiction or qualification here:
https://video2.skills-academy.com/en-us/azure/traffic-manager/traffic-manager-performance-considerations

"If a Traffic Manager service component fails, there is no effect on the DNS name associated with your Traffic Manager profile. The records in the Microsoft DNS servers remain unchanged. However, endpoint monitoring and DNS updating do not happen. Therefore, Traffic Manager is not able to update DNS to point to your failover site when your primary site goes down."

Since our use of the Traffic Manager is primarily used for an update to DNS in case of an endpoint being detected as degraded, it would impact our service overall in this scenario. So, is there any method or built-in way for us to know when a Traffic Manager service component goes down? Everything I saw about metrics and alerting only pertained to the endpoints and not the Traffic Manager itself.

    Hello @Joseph Thomas ,

    Below is the update from the Product group team:

    Both situation mentioned by you are referring to different types of failures. In the first scenario Azure Traffic Manager is resilient to regional outages, due to our service being hosted across multiple regions. The second scenario refers to when Azure Traffic Manager components fail.

    Azure Traffic Manager will log any active events like ongoing service issues on Service health, when our service does go down/a component fails.
    Refer : https://video2.skills-academy.com/en-us/azure/service-health/service-health-overview

    So, you can configure Alerts for Service Health. You can receive an alert when Azure sends service health notifications to your Azure subscription. You can configure the alert based on:

    • The class of service health notification (Service issues, Planned maintenance, Health advisories, Security advisories).
    • The subscription affected.
    • The service(s) affected.
    • The region(s) affected.

    Refer : https://video2.skills-academy.com/en-us/azure/service-health/alerts-activity-log-service-notifications-portal
