File-logger is a library which implements log file rotation: it maintains max X
log files of max size Y, so that you always have latest logs from the device
persisted on the filesystem. By default there are max 10 files, prefixed with
log_, each of max size 5000 bytes.
See mos.yml file for the possible options. At least you'd have to
enable this lib in your app's mos.yml, like this:
libs:
- origin: https://github.com/mongoose-os-libs/file-logger
config_schema:
- ["file_logger.enable", true]
