OpenNMS On the Horizon – September 20th, 2021

Since last time, we worked on updated provisioning, datacollection, event, and monitor/detector docs, logging improvements, Cortex support, flow model updates, flow classification engine improvements, smoke tests, SNMP trap counts, twin API implementation for Trapd, DCT in foundation 2021, Karaf 4.3.3, config management, Vue UI, Vue geomap, ReST mappings, and OpenAPI docs.

  • Stefan worked on improvements to the flow classification engine.
  • Patrick continued his work on converting provisiond-configuration.xml to be in the database.
  • I reworked the smoke test build to put "flaky" tests into a separate build to ease restarts.
  • Christian fixed a bug in how JMX tracks SNMP trap counts.
  • Dustin worked on using the twin API for Trapd configuration.

Release Roadmap

Upcoming October Releases

OpenNMS is on a monthly release schedule, with releases happening on the second Wednesday of the month.

The next OpenNMS release day is October 13th, 2021.

We currently expect a Horizon 28 release, as well as Meridian 2021 update.

Next Horizon: 29 (Q4 2021)

The next major Horizon release will be Horizon 29.

The current roadmap for Horizon 29 includes the following goals:

  • running as non-root by default
  • refactor the Minion's communication to get rid of out-of-band ReST calls to the OpenNMS core
  • add support for persistence of flows to Cortex
  • start the groundwork for replacing the topology UI with a pure-javascript version

Next Meridian: 2022 (Q? 2022)

With Meridian 2021 recently out, we do not yet have a specific timeline for Meridian 2022.

Expect it to include -- at the very least -- the JDK11 requirement and flow aggregation improvements from Horizon 28.

Ideally it will contain work going into Horizons 29 (and probably 30) if our timeline holds. 😅
