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

Since last time, we worked on documentation (SNMP OPAQUE data types, backups, flow classification, trap configuration, graph API), as well as time-series cache optimizations, flaky tests, Horizon Stream (Keycloak integration, detectors, provisioning, login screen), maven fixes, Enlinkd cleanup, time-series deduplication, Kafka, SNMP config encryption, flow ingress and egress, circleci, device config backup, the MIB compiler, OSGi exports, topology UI, event/alarm advanced search, SCV admin UI, ALEC UI, and UI plugin route support.

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 July Releases

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

The next OpenNMS release day is July 13th, 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 just 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 early in its development cycle, but you can expect it to contain, at the very least, the work that's going into Horizon 30.
