OpenNMS On the Horizon – September 7th, 2021

Sorry for the missing OOH last week, I was on vacation.

Since last time, we worked on the config API, OIA, the time-series API, Netflow debugging, Telemetryd config, the flow classification rule parser, trap OID handling, WSman config validation, documentation, syslog hostname resolution, asynchronous node processing in Kafka, UI cleanups, opennms.js, ReST fixes and updates, Vue gomaps and UI proof-of-concept, Cortex flows in Helm, and OpenAPI documentation.

Release Roadmap

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 8th, 2021.

We currently expect a Horizon 28.0.3 release and updated Meridians 2019 through 2021.

Next Horizon: 29 (Q4 2021)

The next major Horizon release will be Horizon 29.

The current roadmap for Horizon 29 includes the following goals:

• running as non-root by default
• refactor the Minion's communication to get rid of out-of-band ReST calls to the OpenNMS core
• add support for persistence of flows to Cortex
• start the groundwork for replacing the topology UI with a pure-javascript version

Next Meridian: 2022 (Q? 2022)

With Meridian 2021 recently out, we do not yet have a specific timeline for Meridian 2022.

Expect it to include -- at the very least -- the JDK11 requirement and flow aggregation improvements from Horizon 28.

Ideally it will contain work going into Horizons 29 (and probably 30) if our timeline holds.
