Adding app insights to APIM instance automatically adds broken "availability tests"

Question

This is the second time I'm posting this, because the first time directed me to a 404 page and my post wasn't saved.

Long story short, I added app insights to my APIM gateway so I could get better error logging.

I checked my logs the next day and see that 4000 new GET requests have failed on the gateway, from different countries all over the world. Looks like a DDOS attack, as our gateway doesn't have any GET endpoints, it has a single POST endpoint.

Spend the next few hours trying to figure what's going on. Finally I google the endpoint being hit (GET /status-0123456789abcdef) and see that this is a health check endpoint that doesn't work on my APIM. Further discover an "availability test" is automatically added after adding app insights to my APIM, and it is configured with a bad URL (for Consumption tiers, it should be GET /internal-status-0123456789abcdef).

Where in the APIM dash is this mentioned or configured? How are we supposed to know when setting this up that all this baked in (broken) stuff will be implemented. Did I miss something when adding app insights? Please let me know, it has cost a lot of time and energy for what seems like a bug.

Thanks in advance.
