It's time for OpenNMS On the Horizon!

In the last week we worked on more Helm bugs and documentation, BMP support, flow enhancements, Karaf commands, gRPC and Kafka, graph service improvements, and more!

Github Project Updates

Internals, APIs, and Documentation

  • Bonnie did more work cleaning up and improving Helm documentation.
  • Ronny and Bonnie worked on converting Helm's documentation to publish with Antora.
  • Chandra worked on persisting BMP data to Elasticsearch.

Web, ReST, and UI

  • Ronny worked on updating the Helm CircleCI build to do automatic merging.

  • I fixed an issue in Helm where an error would be shown while configuring performance datasource filters.

OpenNMS February Releases

On February 4th we released Meridian 2019.1.3 and Horizon 25.2.0.

Both releases contained a few bug fixes, most notably a fix for some NPEs as well as a performance issue in topology processing.

Additionally, Horizon 25.2.0 included an enhancement to the sink API to persist to disk when the Minion can't reach the broker.

Calendar of Events

SCaLE 18x - Pasadena, California - March 5th through 8th, 2020

Until Next Week…

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.
