Traffic Manager (Custom Header Settings)

Question

Hi,

I configured (Custom Header Settings) with some multisite.

host: site1.company.com, host2: site2.company.com, host3: site3.company.com

doubt:

When host1 is degraded, but host2 and 4 are still on, will the status monitor be degraded?

If so, how will I use my accesses for host1, 2 and 3 as a priority to move to another endpoint?

I don't want this, because my condition is when everything is unavailable and not just a website.

I have an Application Gateway for Onpremises and another for the DR website.

It can only be migrated to the DR site when all sites are unavailable.

Thank you.

Azure Traffic Manager monitors its endpoints using Endpoint Monitoring. I am unsure what you mean by 'status monitor', but Traffic Manager will monitor the endpoint to check for outages. If only one instance of many goes down on your endpoint, it should still be responding, and the endpoint will remain up.

For Example, your 'site1.company.com' is hosted on an Application Gateway and one of your instances goes down, the Application Gateway should detect and stop routing traffic to that instance, but the endpoint 'site1.company.com' should still be responsive and distributing traffic.

If all instances go down, then the endpoint will report as unhealthy, and traffic will not be directed to that endpoint.

If all of your sites are hosted in the same place, and you need to fallover to a backup site, you can still use endpoint monitoring with priority routing to send traffic to your DR site in the event your original site becomes unavailable. Traffic will only go to your DR site in the event that your original endpoint becomes unavailable.
