Logback's DBAppender logs all properties in its context and MDC to the database. I would like to control which properties are logged, specifically filtering out certain values, but I can't find any options to do so. The documentation is terse:

The logging_event_property is used to store the keys and values contained in the MDC or the Context

Is it possible to exclude certain properties from being logged? Here is an example: Logback is configured with a `DBAppender` that loads its properties from `vct.properties`: <configuration> <property resource="vct.properties" /> <appender name="DB" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource"> <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource"> <driverClass>com.mysql.jdbc.Driver</driverClass> <jdbcUrl>jdbc:mysql://${log.db.host}:${log.db.port}/${log.db.schema}</jdbcUrl> <user>${log.db.username}</user> <password>${log.db.password}</password> </dataSource> </connectionSource> </appender> <root level="DEBUG"> <appender-ref ref="DB" /> </root> </configuration> `vct.properties` has the connection settings: log.db.host=localhost log.db.port=3306 log.db.schema=logs_development log.db.username=loguser log.db.password=logpass When an event is logged, all of the connection settings are logged: mysql> select * from logging_event_property where event_id=1; +----------+---------------------+-------------------------------------------+ | event_id | mapped_key | mapped_value | +----------+---------------------+-------------------------------------------+ | 1 | log.db.host | localhost | | 1 | log.db.password | logpass | | 1 | log.db.port | 3306 | | 1 | log.db.schema | logs_development | | 1 | log.db.username | loguser | +----------+---------------------+-------------------------------------------+
