guanaco — events

This subproject provides Camel & logging event messages, an Akka-based event dispatcher and some bundles to collect the events in Karaf/ServiceMix and forward them to Kafka topics.

Requirements

• Apache ServiceMix 7.0.1
• Apache Kafka 1.1.1

Installation

config.properties

Before you start, add the sun.net package to the org.osgi.framework.system.packages.extra setting in etc/config.properties.

org.osgi.framework.system.packages.extra = \
    org.apache.karaf.branding, \
    org.apache.karaf.jaas.boot.principal, \
    org.apache.karaf.jaas.boot, \
    sun.misc, \
+     sun.net, \
    javax.xml.stream;uses:=\"javax.xml.namespace,javax.xml.stream.events,javax.xml.stream.util,javax.xml.transform\";version=1.2, \
    javax.xml.stream.events;uses:=\"javax.xml.namespace,javax.xml.stream\";version=1.2, \
    javax.xml.stream.util;uses:=\"javax.xml.namespace,javax.xml.stream,javax.xml.stream.events\";version=1.2, \

org.ops4j.pax.logging.cfg

Update the etc/org.ops4j.pax.logging.cfg file to send log events to all appenders

- log4j.rootLogger = INFO, out, osgi:VmLogAppender
+ log4j.rootLogger = INFO, out, osgi:*

Feature

Afterwards, just install the features (business as usual)

feature:repo-add mvn:io.guanaco.events/features/1.0-SNAPSHOT/xml/features feature:install guanaco-camel-events guanaco-log-appender guanaco-kafka

Events

If everything is working properly, events will be published to two Kafka topics:

• messages will contain a stream of Camel exchange events
• logging will contain a stream of logging events
