Java Util or Log4J logging frameworks are replaced with Logback.
Due to dropped Java Util and Log4J logging frameworks their configuration files /opt/open-xchange/etc/file-logging.properties and /opt/open-xchange/etc/log4j.xml are dropped.
The introduced Logback framework is configured through the configuration file /opt/open-xchange/etc/logback.xml. This file contains examples how to write logs to log files and how to send logs to a remote syslog daemon. By default writing to local log files is configured.
If Java Util or Log4J logging configuration contained any additional configured log level for classes or packages or modified log level, these are migrated by package post installation scripts to the new logback configuration.
Depending whether open-xchange-log4j was installed or not, the package post installation scripts modify the default logback configuration to send logs to a remote syslog daemon.
