In the last week we did the June releases, fixed some bugs, did more work on Docker impovements, continued to work on Minion updates, time-series enhancements, metadata improvements and documentation, flow ReST, and more.

June Releases - Meridian 2019.1.8, Horizon 26.1.1

For the June releases, we put out relatively small updates to Horizon 26 and Meridian 2019.

Both contained a number of fixes and a few enhancements, including Kafka event forwarding fixes. Horizon 26.1.1 also included a couple other bug fixes, most notably a fix for a performance regression in Netflow handling.

For more details, see the June release announcement.

Calendar of Events

July Releases - July 7th, 2020

The next OpenNMS release day is July 7th, 2020. Currently we expect releases from all supported Meridians as well as Horizon 26, due to backported updates for the RRD Newts converter and an update to the default Java version used in Docker images.

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.
