I bet the reason that my server periodically goes offline is because it is being blocked and not because it is actually offline!
It can be the metrics server seeing server down but server actually being up. Seen this multiple times.
A simple method is to record the network traffic. vnstat is a lightweight tool, just works without config. You can view your daily, weekly, monthly, yearly, 5 minute and whatever traffic.
If you need it, you can also have PNG output using a cron job with vnstati.
