Business Manager has the configuration:• Active Log category is " root "• Log level of...

Therootcategory is the parent of all custom logger categories, includingproducts. Therefore, the WARN threshold configured at root applies to theproductslogger unless a more specific category configuration overrides it.

B2C Commerce logging severity is hierarchical: enabling a particular level also enables all higher-severity levels. Salesforce gives the explicit example that when WARN is enabled for a category,WARN and ERRORmessages are logged for that category and its subcategories. Root configuration likewise applies to all custom categories.

Consequently,log.warn()andlog.error()both qualify for persistence.log.info()does not because INFO is below WARN in the severity hierarchy. The exact text placed inside the INFO call doesn ' t matter; logging eligibility is determined by the API method/severity, not whether the message string contains the word " warn. "

This hierarchical configuration allows administrators to maintain a conservative production logging threshold while selectively enabling more detailed logging for particular categories when troubleshooting.
