clog_expire_days specifies the retention period of clog files. When the retention period of a clog file expires, it will be deleted.

This parameter is used with the clog_disk_usage_limit_percentage parameter but has a lower priority. If the clog disk usage exceeds 80% but the interval between the time when a clog file was last updated and the current time is less than the value of clog_expire_days, the clog file will still be deleted.
