Logging
Es ist möglich, über Einträge in der my.cnf das Query-Log und das Slow-Log zu aktivieren:

general_log = 1
general_log_file = /var/log/mysql/query.log
slow_query_log=1
long_query_time=0.1
slow_query_log_file = /var/log/mysql/slow.log

Über einen Custom-Entrypoint können diese Logdateien in die Standardausgabe (stdout) geschrieben werden, damit sie über docker logs bzw. Graylog ausgewertet werden können:
