Alarm Northbounder

The alarm northbounder listens for all northbound alarms. Alarms are sent to a Camel processor, which can filter or transform these, before being sent to the AMQP endpoint.

The alarm northbounder exposes the following properties via the org.opennms.features.amqp.alarmnorthbounder pid:

Property Default Description

connectionUrl

amqp://localhost:5672

destination

Target queue or topic. See AMQP for details.

processorName

default-alarm-northbounder-processor

Named org.apache.camel.Processor implementation used to filter and/or format the alarms.

The default processor, the default-alarm-northbounder-processor, converts the alarms to a string and does not perform any filtering. This means that when enabled, all alarms will be forwarded to the AMQP destination with strings as the message body.

Setup

Start by logging into a Karaf shell.

Update the properties with your deployment-specific values:

config:edit org.opennms.features.amqp.alarmnorthbounder
config:property-set connectionUrl amqp://localhost:5672
config:property-set destination amqp:topic:opennms-alarms
config:property-set processorName default-alarm-northbounder-processor
config:update
