log_quiet

A log you have stopped reading is not a log. Odoo emits a handful of harmless messages at ERROR and WARNING until a real failure is just one more line in the scroll — and once people learn to scroll past them, they scroll past the real one too.

• ✓ Serialization retries the ORM already handles drop to WARNING — still logged
• ✓ Export / unsubscribe / import "ignoring args" noise, gone
• ✓ Crawler junk, stale sourcemaps, Studio boot warnings, gone
• ✓ No filter matches on level or logger alone — every one matches a named message
• ✓ Nine core loggers; the root logger is never touched
• ✓ Any filter switched off with one env var. No uninstall
