OpenNMS On the Horizon – September 13th, 2021

Since last time, we worked on documentation, trapoid/hwEntity handling, Nephron and Cortex, Karaf 4.3, classification rules, config manager upgrade and ReST API, and vue-based UI and geomaps.

Github Project Updates

  • Freddy worked on fixing some smoke tests.

Web, ReST, UI, and Helm

Release Roadmap

Completed September 2021 Releases - Horizon 28.1.0, Meridians 2021.1.4, 2020.1.12, 2019.1.23

In September, we released updates to all OpenNMS Meridian versions under active support, as well as an update for Horizon 28.

Horizon 28.1.0

Release 28.1.0 contains a bunch of bug fixes and enhancements, including a dependency update related to a CVE.

Note that we bumped the minor version on the release because of the changes made in NMS-13479 — in order to optimize the flow classification processing, some significant changes were made behind the scenes. There shouldn’t be any change from a user perspective, but we bumped the version just in case.

The codename for Horizon 28.1.0 is Bumblebee

For a high-level overview of what has changed in Horizon 28, see What’s New in OpenNMS Horizon 28.

Meridian Point Releases

All Meridian releases this month contained minor security updates, so it is recommended that you upgrade.

2021.1.4 adds a fix for additional node metadata showing in syslog events, plus documentation improvements.

For a list of changes, see the release notes:

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. 😅
