Apache Karaf Decanter is a complete monitoring platform for Apache Karaf. It is very extensible, flexible, easy to install and use.

• Collectors: The collectors are responsible of harvesting monitoring data. Two kinds of collectors are available: * the polling collectors are invoked periodically by a scheduler * the event driven collectors react to some events. It's very dynamic (thanks to the OSGi services), so it's possible to add a new custom collector (user/custom implementations).
• Dispatcher: The dispatcher is called by the scheduler or the event driven collectors to dispatch the collected data to the appenders.
• Appenders: The appenders are responsible to send/store the collected data to target backend systems.
• Processor: The processors can manipulate the internal Decanter events between the collectors and the appenders. Decanter provides ready to use processors (aggregate, groupBy, camel, ...).
• Alerting: the alerting layer provides a checker, responsible of testing values of harvested data (coming from the collectors) and send alerts when the data is not in the expected state.

Apache Karaf Decanter is available as a Karaf features. The following command registers the Karaf Decanter features repository.

karaf@root()> feature:repo-add decanter
