#Python

Logs, traces and metrics from a dozen containers pushed over OTLP into one deliberately dumb collector, then read in Kibana — with a disk queue so a restart loses nothing, audit events counted exactly once, and the rule that telemetry must never become a failure point.

Build output, not my own code, was filling the disk: five projects shrank from 21 GB to 749 MB once the rebuildable folders were gone. I automated that cleanup instead of buying a bigger SSD, without trusting folder names or confirming hundreds of folders by hand.
