is a OSGi-based runtime which provides a lightweight container onto which various components and applications can be deployed. Apache Karaf uses either Apache Felix Framework or Eclipse Equinox OSGi frameworks Provisioning: Apache Karaf supports a large set of URL where you can install your application (Maven repository, HTTP, file, etc). It also provides the concept of "Karaf Feature" which is a way to describe your managed directly from a main instance (root). APACHE KARAF OVERVIEW 5 • OSGi frameworks: Apache Karaf is not tight to one OSGi framework. By default, Apache Karaf runs with Apache Felix Framework, but

The first thing to do is to add the Decanter features repository in Karaf: Or Now, you have to install the collectors, appenders, and eventually SLA alerters installation of the decanter-collector-log feature is enough. NOTE The Decanter log collector is using osgi:DecanterLogCollectorAppender appender. In order to work, your Apache Karaf Pax Logging configuration actually process the message logs. log4j.rootLogger = DEBUG, out, osgi:* log4j.rootLogger = DEBUG, out, osgi:DecanterLogCollectorAppender, osgi:VmLogAppender 1.2.3.
