This is no longer possible and configuration must be done through an XML file named logback-spring xml. ## External configuration file You can instruct Valsights `Logback` component to use an external configuration file with a system property: ``` $ ./gradlew -Dlogging.config=/Users/me/config/logback-spring.xml bootRun ``` In our distribution folder you can simply add the system property to one of the following files, depends on your environment: * **Windows** * *windowsservice/valsightservice.xml*: simply add the property to the tag * *bin/valsight-server.bat*: Add the property to the already declared variable DEFAULT\_JVM\_OPTS * **Unix** * *bin/valsight-server*: Add the property to the already declared variable DEFAULT\_JVM\_OPTS ### Example logback-spring.xml configuration files:

Configure Logback given the number of days to keep the logs to archived

Configure Logback given the size of the files and the number of logs to archive

Download the attached file and configure manually the following parameter to customize the number of days that a log is kept.
