The default log level for user plugins is "warn". To change a plugin log level, add the following to $JFROG_HOME/artifactory/var/etc/artifactory/logback.xml:
<logger name="my-plugin">
<level value="info"/>
</logger>The logger name is the name of the plugin file without the ".groovy" extension (in the example above the plugin file name is my-plugin.groovy). The logging levels can be either error, warn, info, debug or trace.
