I had Azure AKS monitoring turned on for a minuscule, essentially unused hobby project. After about four months the monitoring costs suddenly exploded from about $4/mo to about $4k/mo.

No idea what happened and MSFT support couldn't tell me what was happening because at more than $100/day burn rate on a hobby project I started deleting everything connected with the effort as fast as possible.

All I know is my AKS wasn't exploding. Services were still responsive and acting normally in their minuscule cluster, this was just a logging cost explosion.

Also billing alerts are your friend.
