It is very extensible, flexible, easy to install and use. Apache Karaf Decanter is composed into: * Collectors and SLA Policies The collectors are OSGi services 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). The collectors are also responsible of checking the SLA, and delegate to a notifier. * Scheduler The scheduler service is responsible to call the Polling Collectors, gather the harvested data, and delegate to the dispatcher. * 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 systems. * Notifier The notifier is called by the collectors' SLA. The notifier uses external system to "publish" the SLA alert. * Console & Web UI The console is responsible of both SLA configuration and dashboard view. Getting Started =============== Apache Karaf Decanter is available as a Karaf features. The commands below start the jmx collector, log collector and an appender to a local elasticsearch instance on the default port. Prerquisite is a running elasticsearch instance. feature:repo-add mvn:org.apache.karaf.decanter/apache-karaf-decanter/3.0.0-SNAPSHOT/xml/features feature:install decanter-simple-scheduler decanter-collector-jmx decanter-collector-log decanter-appender-elasticsearch Features ======== Alternatively you can install exactly the features you need. * decanter-simple-scheduler Very simple Decanter Scheduler that polls collectors in a fixed time interval. * decanter-collector-log Collector listening for all log messages happening in Karaf. * decanter-collector-jmx Collector harvesting the JMX MBeans metrics. * decanter-appender-log Appender that sends the collected data as log messages. * decanter-appender-elasticsearch Appender that sends the collected data to a Elasticsearch database. * elasticsearch Elasticsearch running inside Apache Karaf * kibana Kibana running inside Apache Karaf.
