The logging in Qlik Sense implements a custom appender, QSRollingFileAppender, which is based on the log4net component. The custom appender is used internally by the Qlik Sense logging system.
QSRollingFileAppender and some of the built-in, predefined appenders in the log4net framework can be used to configure customized logging, which is specified in the local log configuration file, LocalLogConfig.xml.
QSRollingFileAppender can also log events in the local log file (for example, the Microsoft Windows event log) or send log information to a remote log server.
