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

Last week was DevJam, so keep that in mind when you get excited about some of the projects you see. ;)
Plenty of these are proof-of-concept work that may or may not make it into a release.

Anayway, since last time, we worked on Horizon Stream (Minion RPC and gateway, operator improvements, hashicorp vault support, device UI and events), documentation (quick start guide, grafana, flows), OpenTelemetry, VNC integration, Sonar (CI workflow, bug fixes), Enlinkd scheduling and OSPF area support, and hashicorp vault SCV integration (including REST).

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

September 2022 Releases - Horizon 30.0.3, Meridians 2022.1.7, 2021.1.19, 2020.1.27, 2019.1.38

In September, we released updates to all OpenNMS Meridian versions under active support, as well as Horizon 30.0.3.

Meridian Stable Updates

Meridians 2019.1.38, 2020.1.27 , 2021.1.19 , and 2022.1.7 contains a couple of bug fixes.

For a list of changes, see the release notes:

Horizon 30.0.3

Release 30.0.3 contains quite a few bug fixes as well as number of small features and security fixes.

For a high-level overview of what has changed in Horizon 30, see What’s New in OpenNMS Horizon 30.

For a complete list of changes, see the changelog.

The codename for Horizon 30.0.3 is Chipmunk.

OpenNMS Helm 8.0.1

Helm 8.0.1 is primarily a bugfix release.

It contains a number of small fixes and enhancements to improve querying of nodes and interfaces.

It also contains a large number of node dependency updates.

Please note that Helm is still targeted to Grafana 8.
Work is underway to update to support Grafana 9.

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 October 12th, 2022.

We currently expect updates to Horizon 30.

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.
