Azure Front Door - Determine which origin is unavailable
Have a Azure Front Door setup currently with 2 origin groups. In each of the Origin Groups, I have added 1 origin.
The first origin group is working fine, and the Origin Health metric was at 100%.
I added a second origin group, which does not work, and the Origin Health is now 0.
However, the first endpoint works fine through Front Door. First question, should not this return in a Origin Health of 50% ? 1 out of 2 origins is unavailable for some reason.
I tried to figure out in the Portal, if you can see the actual status of the origins, but I have not been able to locate it.
Looking in the logs, FrontDoorHealthProbeLog, there actual is no info either, as far as I can see, on which of the thats unavailable.
According to the docs , I could guess that the "OriginName" could be the origin (URL/hostname of the backend/origin service), but that does not seem to be the case.
Can anyone point me in the direction of spotting which of the backends (origins) are down?
In the Metrics of your Front Door, apply splitting by Origin and you'll get this graph where you can see what the status of each origin is.
