/**
 * This is the default Limbus Monitoring activator that searches for a valid monitoring configuration and initializes
 * the monitoring facade. The configuration is determined by the following strategy:
 * 
 * Try to find a valid configuration in conf/-directory. The system searches for a monitoring.xml in the
 * Limbus default configuration directory.
 * If nothing was found the classpath is searched for a monitoring.xml
 * If still nothing was found, the Limbus Monitoring Facade defaults to a no-op state.
 *
