The long-awaited OpenNMS Horizon 19 (code name: Ice Hockey) is here!

It is chock full of bug fixes and new features, most notably full support for OpenNMS's polling and data collection APIs on the Minion.

    • Polling
    • SNMP data collection
    • SNMP link discovery
    • Syslog reception (sent to OpenNMS via JMS or Apache Kafka)
    • SNMPv1/v2/v3 trap reception (sent to OpenNMS via JMS or Apache Kafka)
  • Automatic provisioning of Minions: Minion devices will be added to the Minions requisition and monitored for connectivity with OpenNMS.
  • GraphML Topology Provider: A new Topology Provider is available that reads GraphML formatted graphs and displays them in the the Topology UI.
  • OpenNMS Elasticsearch ReST Forwarder: This Elasticsearch forwarder can store events, alarms, and alarm state changes in Elasticsearch for archival or searching. It is compatible with all currently supported versions of Elasticsearch.
  • Unified JAAS Authentication: The web UI, the Apache Karaf OSGi console, and the built-in ActiveMQ broker all use unified authentication.
