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

Since last time, we worked on documentation (OIA, upgrades, non-root, BGP session monitor, introductions, Alarmd, criteria API, XML collector, device config backup, event datacollection, new UI), boostrapping Horizon Stream, updating various dependencies, Trapd, OIA, SSH authentication, Cucumber integration tests, asset search, cron-based Quartz config, hardware inventory, and Helm flows.

Releases and Roadmap

Upcoming May Releases

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

The next OpenNMS release day is May 11th, 2022.

We currently expect an update to Horizon 29, plus Meridians 2019 through 2022.

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: 2023 (Q1 2023)

Meridian 2023 is early in its development cycle, but you can expect it to contain, at the very least, the work that's going into Horizon 30.
