Load Balancing Monitor Flooding Webserver With Too Many Requests

We are using the Cloudflare load balancer and it has been flooding our nginx webserver with healthcheck requests. Our monitor is set to check every 60 seconds (so we should have in theory 1440 requests per day from the monitor 24*60) but in reality we are getting 7-10 checks per second by the monitor.

I see someone else had the same issue here: DOS attack by Cloudflare against our website - no support provided

And this was solved by cf-scott: https://community.cloudflare.com/u/cf-scott

But the solution was not published publicly. I was hoping someone could publish the solution on the forum so that it could be of use to me and anyone else who is using the CF load balancing monitor.
