Sometimes it might happen that you need “enriched” notifications from OpenNMS. Suppose you would like to send a notification including an information which is present on the asset view of your node: the Event Translator of OpenNMS is what you’re looking for.
At this Event Translator web page you can find the official documentation from OpenNMS but for a full implementation I suggest you to have a look at the following post.
Scenario: I will enrich the notification just for a specific category of devices that I use to call TimeClock. When one of these devices is down, It will send an enriched notification that include node label, ip address of the primary snmp interface and the description stored on the asset of the node. By default on OpenNMS notifications you won’t get these 2 additional information.
