OpenNMS On the Horizon – February 14th, 2022

It's time once again for OpenNMS On the Horizon.

Since last time, we worked on moving configs to the new config manager API, requisition validation, Docker image updates, test infrastructure improvements, system report improvements, Nephron, flow, and SNMP property extender docs, Adoptium/Temurin JDK support, device config backup, Helm docs, Karaf shell, Telemetryd, JMX RMI, IPC, service startup, Maven, Non-Root, Jetty config, UI dependencies, web plugins, event configuration UI, and provisioning UI updates.

Release Roadmap

Completed February 2022 Releases - Horizon 29.0.6, Meridians 2021.1.11, 2020.1.19, 2019.1.30

In February, we released updates to all OpenNMS Meridian versions under active support, as well as Horizon 29.

Meridian Stable Updates

Meridians 2019.1.30 and 2020.1.19 contain a number of bug fixes and security updates.

On top of those changes, Meridian 2021.1.11 includes few additional bug fixes and a doc update.

For a list of changes, see the release notes:

• 2019.1.30 (Pipitea)
• 2020.1.19 (Mid-Ocean Ridge)
• 2021.1.11 (Magellan)

Horizon 29.0.6

Release 29.0.6 contains all of the fixes included in the Meridian stable release, as well as a number of additional bugfixes and enhancements.

For a high-level overview of what has changed in Horizon 29, see What’s New in OpenNMS Horizon 29.

For a complete list of changes, see the changelog.

Thanks to Sahil Tikoo from Etisalat for reporting the Grafana endpoint issue.

A note about security issues: we have traditionally created CVEs in a pretty ad-hoc manner. We are in the process of formalizing how we’ll be doing so going into the future.

The codename for Horizon 29.0.6 is Dodo.

Upcoming March Releases

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

The next OpenNMS release day is March 9th, 2022.

We currently expect updates to Horizon 29 and all supported Meridian releases.

Next Horizon: 30 (Q2 2022)

The next major Horizon release will be Horizon 30.

Horizon 30 is currently expected to have the following features:

• the start of a new Vue-based UI using the Feather Design System
• thresholding support for Flow data
• initial work moving configuration from XML files to the database -- the first config file implemented on top of the new system will be provisiond-configuration.xml
• support for running OIA plugins on Minion and Sentinel
• support for backing up router configuration files

Next Meridian: 2022 (Q1 2022)

The current expectation is that we will release Meridian 2022 in March of 2022.

It will be based on Horizon 29.
