We develop Drools based applications and use Guvnor as a a repository. Hard-coding the hostname where Guvnor runs is not an option for us because the names are different in each installation and we do not want to modify all the changeset.xml files for each deployment.

Instead we would pass one (or more) Resources to the KnowledgeAgent and let it do the monitoring. This would allow us to build URLs dynamically from our system environment configuration.
