log level

[manojmukkamala]

Hi, it looks like log level defaults to INFO: command += " --stats 0.1s --stats-unit bytes --use-json-log -v"

is it possible to override it to something else like NOTICE?

The line you are referring to is only called for transfer operations, so commands like copy, move, etc.

The Info log level is required as it provides the update information and file sizes. Without it the library cannot display any updates or provide the update dictionary.

So changing the log level here would not make much sense.

Example json update:

{
   "time":"2025-07-12T16:20:41.6441918+02:00",
   "level":"info",
   "msg": "<Some message>",

agreed! i don't mean to change the default value but providing the user a way to override.
I am using args=["--log-file=/rclone_app/logs/documents.json"] to collect the logs and the log files are growing very fast so limiting the log level to something like NOTICE would help.
