It’s time for OpenNMS On the Horizon!
Sorry this is out a bit late, I’m super sick. I’ll probably write this and go right back to bed.
In the last week we did a lot of preparation for Horizon 24, plus continued work on the graph service, RPC and sink metrics, and some UI work.
Github Project Updates

- I cleaned up some startup script issues in prep for Horizon 24.
- Jesse worked on extracting additional event parameters from varbind values based on regular expressions.
- Jeff fixed upgrades to keep karaf shell history.
- Matt made some fixes to prefab graph support in OIA.
- Chandra continued to work on enhancing metrics and tracing in the RPC and Sink APIs.
- Lots of documentation work was done in preparation for Horizon 24’s release.
- David started working on fixing thresholds handling node category changes.
- Patrick worked on persisting graph repository collections.
- Ronny did more work on improvements to our docker containers.
- Web & UI
- David did more work on the Helm integration for root cause handling in situations.

April OpenNMS Horizon and Meridian Releases
OpenNMS Horizon (Rapid Release)
April marks a new major Horizon release: OpenNMS Horizon 24. The most notable improvements are big updates to alarm correlation (including support for Tensorflow-based AI correlation), a new developer API for creating OpenNMS plugins, a web UI refresh, and flow enhancements.
For a complete list of changes in Horizon 24, see the release notes.
OpenNMS Meridian (LTS)
We also updated Meridian all the way back to Meridian 2016, primarily to fix a bug in SNMP processing of certain buggy agent behaviors that could cause an out of memory exception.
For a complete list of changes, see the release notes:
