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

Since last time, we worked on documentation (quick start guide, ALEC, partial config updates, cortex time-series), Horizon Stream (notifications, unit/integration test, ignite detector client, operator, Minion gRPC, Grafana, Keycloak, map UI, widgets, trap processing), SNMP metadata provisioning, ALEC (release work and UI), dynamic CI config, datachoices (notifications and outages, poller fixes), Enlinkd collection scheduling, Docker, offheap storage, dependabot updates, filter rules, Sonar, OpenTelemetry, and Helm.

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

OpenNMS.js 2.5.0 Released

OpenNMS.js 2.5.0 contains a bunch of dependency updates including a move to core-js v3 for compatibility, as well as a few build system cleanups, fixes for querying SNMP interfaces by node ID and a query fix for 0-indexed enums.

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
  • more stuff, which I haven't had a chance to go back and enumerate yet, watch this space :D

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.
