New Features

ALEC

Meet ALEC, the first open source AIOps platform for fault correlation. ALEC (Architecture for Learning Enabled Correlation) enables users to quickly detect, diagnose, and resolve situations across the entire IT infrastructure. For more information, visit: https://alec.opennms.com

Integration API

A new API has been introduced that presents a simplified interface to a number of integration points including subscribing to events and alarms, writing custom detectors and pollers, and more.

Improvements

New Web UI

The web UI has gone through a major refresh, simplifying the HTML and optimizing space. Browser notifications are now supported in the Web UI. Browser session timeout is now disabled by default.

Flows

Flows are now grouped by conversations using applications instead of ports. This changes the way statistics about flows are presented and grouped.

Helm 3.0

Helm 3.0 contains a large number of changes, mostly related to the Alarm Table in the Fault Management Data Source. Also, fixes for running under Grafana 6.

Metadata

There is now experimental support for associating arbitrary metadata with nodes and interfaces. For details on using the metadata APIs, see the Admin Guide and the Developer Guide.

Topology

Topology information has been refactored into a more generalized graph service that includes ALEC alarm and situation topology. Topology data can be sent to Kafka alongside nodes, events, and alarms.

BSM

Applications can now be added as an edge to a Business Service. This allows you to aggregate IP services.
