Health monitoring of web pages without using GET check

I am looking for a solution to monitor the health (DOWN or UP) of my web pages.Let's say I have three services,

site.com/datasite.com/usersite.com/id

Now, what I can do is that I can create a GET request which will be served every second and check if response status code is 200 OK. If it is anything else than 200 OK, then it will trigger an alert. But, I don't want to hit the server continuously, as it will create unnecessary logs. I am using a mongodb logger. What is the recommended way to achieve this?
