I've tried setting up a uptime monitor on my CDN, to keep track of response times and to get notified if something were to happen to it. Problem is; my checks are filling the report logs with junk. There is nothing strange about that, the check is making a HEAD request to some URL and it gets logged.
But; this means that the cache hit value gets either very high or very low. And this value is a bit interesting on a CDN so would like to avoid that. A port monitor does not leave any trace in the logs.
So then comes my question:
Is a monitor for port 443 a (at least somewhat) good indicator that the web server is fine? Would it catch a 500 error?
