The following forms allow to configure logging in Apache Marmotta. Logging in Marmotta is based on
Logback and uses the following concepts:
appenders are log output destinations (either the console, a logfile, or a syslog facility);
each appender has at least a pattern describing the layout (following the
Logback Pattern Layout) and a maximum
level; messages with higher level are always ignored by the appender
modules are logical components in Marmotta that represent a certain functionality (e.g. "SPARQL");
each module has a loglevel and a list of appenders to which it will send its output.
