DATABASE SETTING "log.level" TO "TRACE";`

Memgraph creates daily log files and retains them for 35 days by default. You
can change the retention period using the
[`--log-retention-days`](/database-management/configuration#other) configuration
flag.

The configuration set during runtime will be applied only for that session.

You can check the log level by running `SHOW DATABASE SETTING "log.level";` query.
