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

Since last time, we worked on documentation (Minion, plugin API, events), Horizon Stream (monitoring, time-series storage, Kubernetes operator, notifications, PagerDuty, Skaffold/Tilt config, device/appliance UI and maps), Enlinkd scheduling, datachoices telemetry, CI dynamic config, build assembly, ALEC (situations backend and UI), JMX collection, time-series off-heap storage, and password complexity checks.

Github Project Updates

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 August Releases

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

The next OpenNMS release day is August 10th, 2022.

We currently expect updates to Horizon 30 and all supported Meridians.

Next Horizon: 31 (Q4 2022)

The next major Horizon release will be Horizon 31.

Since Horizon 30 was only recently released, there is nothing concrete on the roadmap for Horizon 31 yet.
Stay tuned for details when they come.

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.


Note that this is just based on current plans; dates, features, and releases can change or slip depending on how development goes.
