False positives in the case of server monitoring are extremely rare and easy to detect when they do happen.
Can you imagine if your server monitoring runs once per minute and randomly fails 1/100 times? You'd be getting panic-inducing server is down emails many times per day. Such server monitoring would produce little to no value as you'd quickly ignore them as noise, just like you should avoid doing more tests like this on your body.
Additionally, CTs in particular produce ionizing radiation and increase your risk of cancer. If monitoring your server increased the risk of it failing, would you still want monitoring on it?
