It's time for This Week in OpenNMS!

In the last week we continued work on OCE improvements, Java 9+ changes, UI cleanups, Helm and OpenNMS.js updates, and much more!

Github Project Updates

  • Internals, APIs, and Documentation
    • Patrick continued his refactor of the topology provider to use the new graph service.
    • David continued his work on a configurable meta model for OCE.
    • Dustin kept working on supporting arbitrary metadata on nodes.
    • Markus did more work on the CXF upgrade to 3.2 to facilitate running on newer JDKs.
    • Ronny worked on performing OpenNMS builds in CircleCI.
    • Jesse did more work on fixing an SNMP loop caused by bad agents.
    • Chandra worked on improving our error/exit code handling for graceful JVM shutdown.
    • Jesse updated Alarmd to allow for using node category when handling alarms in Drools.
    • Jesse worked on fixing an issue where related alarms were not properly removed from situations.
    • Matt did more work on the "direct" OCE datasource, which allows running OCE in the OpenNMS JVM.
  • Web & UI
    • Christian worked on updating the node detail page to make the number of services displayed configurable.
    • Markus worked on some new UI changes to the web navbar.
    • Christian updated event and alarm search to include logMessage and description.
    • Jesse did some changes to support user-specified (manual) links in the topology UI.
    • I worked on a number of Helm enhancements, including creating an inventory datasource, as well as making a custom filter panel that can do dynamic filtering on the alarm table.
    • Markus worked on cleaning up some table layout issues in the new Bootstrap 4 UI.
    • I added support for isAcknowledged to OpenNMS.js and fixed some bugs in property caching in ReST DAOs.

OpenNMS Horizon and Meridian March Releases

Last week we put out updated OpenNMS Horizon and Meridian releases. These were, for the most part, small bug fix releases as we prep for Horizon 24 (which Meridian 2019 will be based on).

If you are running Meridian 2018 or Horizon 23, it is strongly recommended you upgrade. An SNMP agent loop bug was fixed in both of those releases, as well as an Alarmd deadlock that affects all Horizon 23 versions.

For a complete list of changes, see the release announcements:

Until Next Week…

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