OpenNMS On the Horizon – April 15th, 2019 – OCE is Now ALEC, TWiO is Now OOH, RPC Tracing, Horizon 24, Helm, and More!

In the last week we did a lot of prep work for Horizon 24, including better debug tracing for RPC and geocoder fixes, as well as other ALEC updates.

Oh, and we renamed OCE to ALEC (Architecture for Learning Enabled Correlation) now that it has a TensorFlow-based engine. And I renamed This Week in OpenNMS to OpenNMS On the Horizon because c’mon, you gotta admit it’s a better name. Get it? Horizon? Fine. Well it’s staying this way whether you like it or not.

Github Project Updates

• Internals, APIs, and Documentation
  • Jesse and Ronny continued to work on a CircleCI workflow for OpenNMS builds.
  • Chandra fixed loading a couple of the less common timeseries strategies that got broken in a refactor.
  • Chandra did wrap-up on opentracing support for RPC communications.
  • Markus started in on reworking our geocoder support, including a configuration UI.
  • Dustin worked on making poller configuration applicable to more than one service through wildcards.
  • Matt did more work on running ALEC on the JVM.
  • I updated the dependencies for Horizon 24 so it can be installed without requiring a specific JVM, as well as allowing JDK 8 through 11.
  • Jesse added support for pushing topology edge updates with a Karaf command.
• Web & UI
  • David did more work on the UI for root cause submission.
  • I worked on more enhancements to Helm, including mouseovers for alarm logs, auto-wildcarding for text search in the filter panel, and a number of bug fixes and maintenance chores.
