This Week in OpenNMS – March 18th, 2019 – Karaf Upgrade, Correlation, Bug Fixing, and Much Much More!

It's time for This Week in OpenNMS!

I'm sorry for missing last week's TWiO, but I was busy in the Caribbean with a bunch of nerds. Meanwhile, everyone was apparently very busy and much more productive without me. Maybe I should get back on the boat.

In the last couple of weeks we did a ton of bug fixing, updated our embedded Karaf to 4.2, and did a ton of work on correlation. Plus a whole lot of other great stuff.

Github Project Updates

• Internals, APIs, and Documentation
  • David worked on fixing up flapping syslog time tests.
  • Jesse did more work on fixing potential deadlocks in Alarmd.
  • Chandra did more work making sure 3rd-party JDBC drivers can be loaded on Minion.
  • Markus wrapped up his work to update our embedded Karaf to 4.2.
  • Patrick did more work making improvements to the events:stress command.
  • Antonio made enhancements to bridge topology generation when events are sent.
  • Matt updated OCE test infrastructure to use a vanilla Sentinel container and worked on integrating the old OCE end-to-end tests into OpenNMS's build.
  • David did more work on the configurable meta-model for OCE.
  • Ronny worked on RPM CI and deployment for OCE.
  • Dustin did more work on handling flow packets that mix templates and data.
  • Antonio fixed an issue with ack escalation events.
  • Matt did more work integrating links from enlinkd into the OCE graph.
  • Matt fixed an issue with the Kafka datasource blocking OCE engine initialization.
  • Ronny started working on a documentation pipeline for OCE.
  • Jesse started work on an alternative OCE plugin that uses TensorFlow for clustering alarms.
  • Chandra fixed an issue with leftover artifacts in .m2 after upgrading the Minion.
  • Jesse made a number of changes to expose useful data including node model updates, exposing requisition providers, and event listeners in the API.
  • Jesse added support to snapshotting data in OCE.
  • Chandra fixed a bug in the Minion status poller config that could cause timeouts or incorrect status.
  • David Hustace improved the documentation for the OCE project.
  • Alejandro improved our Docker images so they can run on OpenShift infrastucture without requiring root permissions. These changes should available alongside the release of Horizon 24.
• Web & UI
  • I got a working inventory datasource put together for Helm, and started on a filter panel using it.
  • Chandra fixed an issue in the ReST adapters that could cause values to be truncated to MAX_INT.
  • Markus did a few fixes and improvements in the new Bootstrap 4 UI.
  • Alejandro fixed an issue in the MIB parser UI.
