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://docs.microsoft.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://docs.microsoft.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.
