Log files rotate when they reach 10 MB and, as with console output, `ERROR`-level,
`WARN`-level, and `INFO`-level messages are logged by default. Size limits can be changed
using the `logging.file.max-size` property. Previously rotated files are archived
indefinitely unless the `logging.file.max-history` property has been set.
indefinitely unless the `logging.file.max-history` property has been set. The total size
of log archives can be capped using `logging.file.total-size-cap`. When the total size of
log archives exceeds that threshold, backups will be deleted. To force log archive cleanup
on application startup, use the `logging.file.clean-history-on-start` property.
NOTE: The logging system is initialized early in the application lifecycle. Consequently,
logging properties are not found in property files loaded through `@PropertySource`
