How to disable scheduler log

Install / Update Setup

I see a whole lot of scheduler logs which are created in log directories of site as well as frappe-bench log directory:

  1. /home/frappe/frappe-bench/logs
  2. /home/frappe/frappe-bench/sites/<site.name>/logs

They pollute the log files and the frequency of update is also quiet quick. Also size of files swells too quickly.

How to disable these scheduler log or best case decrease the frequency only for critical error.
