In the last week we continued to work on the new documentation framework, performance and bug fixes, flow handling, ticketing, monitors, ReST, and BSM.

Github Project Updates

Internals, APIs, and Documentation

  • Ronny and Bonnie continued to work on tweaking and improving the Antora doc rework.
  • Jesse made a performance improvement to event label lookups, as well as introducing parallel event processing in the Kafka producer.
  • Jeff worked on adding support to Newts for connecting to a Cassandra Datastax database.
  • Chandra did more work on fixing up some bugs in ticketing change handling.
  • I worked on improving smoke test runs.
  • I changed the Trapd minion config so that SNMPv3 config refresh time is configurable.
  • Craig continued to work on modernizing the Selenium monitor.
  • Chandra added an in-memory ticketing plugin to simplify testing the ticketing API.
  • Stefan continued to work on performance improvements to flow processing.
  • Christian added a flag to clear %dpname% in alarms, to be used in cases where people run multiple minions in a single location.
  • Marcel did more work on documenting undocumented detectors.

Web, ReST, UI, and Helm

  • Jane wrapped up her initial implementation of OpenAPI swagger support for our ReST interfaces.
  • Christian fixed an issue with changing reductionKey in the BSM editor.

Release Roadmap

April Releases

The next OpenNMS release day is April 6th, 2021.

Currently we expect new bug fix releases for Horizon 27 and Meridians 2019 and 2020.

Next Horizon: 28 (Q? 2021)

The next major Horizon release will be Horizon 28.

Horizon 28 will still be coming down the pipeline soon.
Currently, we hope for it to contain the move to building with JDK 11 (and, consequently, a requirement to only run on JDK 11 or higher), QoS flow aggergation, and some other improvements in the pipeline.

Next Meridian: 2021 (Q2 2021)

Meridian 2021 is on track for a release in 2nd quarter of 2021. It is expected to be based on the Horizon 27.1 codebase, which means it will contain all of the bug fixes and new features introduced in Horizon 26 and 27.


Note that this is just based on current plans; dates, features, and releases can change or slip depending on how development goes.

Until Next Time…

If there’s anything you’d like me to talk about in a future OOH, or you just have a comment or criticism you’d like to share, don’t hesitate to say hi.
