Python3 monitoring script for WEB servers in the DNS load balancing Environment

Many large websites use multiple server (IP) addresses to provide services for a single website to relieve stress and avoid spof. This includes using DNS round training for load balancing. But for administrators, how can they monitor these servers? The following script can help you implement it. Importsocket, urllib. parse

But for administrators, how can they monitor these servers?

The following script can help you implement it.
