The Wiki is Dead, Long Live the (Discourse) Wiki

As many of you know, the OpenNMS wiki has long been a bit of a mess.
A bunch of folks have been doing the hard work of migrating the useful bits to the Discourse.

At this point, the value of keeping the wiki around is lower than the value of closing it down, so we are going to finally do just that, on December 1st.

We'll keep an internal copy around in case we need to migrate anything else that got missed, so if you can think of something specific that really needs moving over, let us know.

The new location for general (non-versioned) configuration tips and other useful stuff in the Knowledge Base category of the OpenNMS Discourse.

Knowledge Base.


Tell your friends.

Release Roadmap

Upcoming December Releases

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

The next OpenNMS release day is December 8th, 2021.

We currently expect a minor update to Horizon 29.

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
  • 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 Q1 of next year. It will be based on Horizon 29 plus any bug fixes that happen between November and the Meridian release.
