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

Since last time, we worked on documentation (notifications, daemons, "deep dive", Helm), Horizon Stream (Skaffold/operator/gateway infrastructure, Minion, graph API, metrics, containers, device UI), ALEC (situation REST and UI), CircleCI improvements, Docker improvements, datachoices/telemetry, JICMP6, off-heap improvements, SNMP4J, location, config manager, and interface REST, and Helm (entity and flow datasource improvements).

Coming Soon: JIRA Migration

We will be migrating our JIRA issue-tracker from a self-hosted version to Atlassian's cloud version.
I don't have a timeline for this yet, but expect it in the coming months.

If you currently have an account at the OpenNMS issue tracker your account should already be migrated to JIRA Cloud, but you will need to perform a password reset with the "Can't log in?" link before you can log in.

Releases and Roadmap

Upcoming September Releases

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

The next OpenNMS release day is September 14th, 2022.

We currently expect updates to Horizon 30 and all supported Meridian releases.

Next Horizon: 31 (Q4 2022)

The next major Horizon release will be Horizon 31.

It will contain a number of improvements, including:

  • a refactoring of flow APIs including support for some flow hooks in the plugin API (plugin API 1.1.0+)
  • major improvements and refactoring in Enlinkd's bridge topology mapping and collection scheduling

Next Meridian: 2023 (Q1 2023)

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

Open Source Day 2022 - September 16th

The OpenNMS Group is proud to support Grace Hopper Conference's Open Source Day (OSD) 2022, and our very own Sandy Skipper is serving on the OSD Steering Committee.

OSD is an all-day hackathon in which participants of all skill levels learn about open source while contributing to projects designed to solve real world problems.
The goal is to celebrate and encourage women in open source.

OSD will take place as a pre-event on Friday, September 16 from 8am - 3pm PDT. Participation is open to anyone who has a GHC registration ticket (in-person or virtual).

For more information, contact Sandy Skipper or see the OSD site.
