The current documentation says following:
Logging By default, Odoo displays all logging of level info except for workflow logging (warning only), and log output is sent to stdout. Various options are available to redirect logging to other destinations and to customize the amount of logging output.
You can change it by starting Odoo with following parameter or defining this parameter in Odoo's config file.
--logfile <file>sends logging output to the specified file instead of stdout. On Unix, the file can be managed by external log rotation programs and will automatically be reopened when replaced
