Reduces surface area of attack, you never know when a 0day is going to be found. Exposing monitoring/metrics is particularly interesting as it exposes a lot of information to an attacker, if they're trying to starve your machine of a resource or whatever.

Exactly. They have direct access to your vitals and can push certain buttons to figure out how your system is running to brute-force that attack, ultimately ruining whatever they intended to do.

I'm probably going to change how publicly accessible my monitoring view is soon, but for now, it seems pretty cool for everyone to see.

Indeed it was cool.

Would love to get a link to a screenshot of your system's resource monitoring. The description of each panel & eache metric was quite useful!

It's still public as of now.
