View Running Bundles
The Nexus Repository Manager application runs on the OSGi container Apache Felix. All features and plugins are managed by the container and are implemented as OSGi bundles. The Bundles feature view is available in the System section of the Administration main menu. It allows you to inspect a list of all the OSGi bundles that are deployed as part of the application and access detailed information about each bundle.
Find out more about OSGi and OSGi bundles on the website of the OSGi Alliance.
