OpenNMS On the Horizon – August 15th, 2022

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

Since last time, we worked on documentation (Plugin API, daemons, Minion, Helm), Horizon Stream (Minion, build system, Keycloak, operator/Skaffold improvements, notifications, metrics, maps, and device UI), CircleCI, Enlinkd, datachoices telemetry, SNMP provisioning policy handling, ALEC situations, the location REST service, regex node filters in Helm, web validation.

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 Plugin API 1.1.0

OpenNMS Plugin API 1.1.0 was released last week, with a number of improvements to the features available to plugin implementers.

• support serialization of time-series data to disk
• support APIs for flow persistence in plugins
• remove the dev flag from yarn for UI plugins

Please note that some plugin features will only be available in the upcoming Horizon 31 release.

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 Meridian 2022.

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.
