This Week in OpenNMS - October 22nd, 2018 - More Horizon 23 Prep, Correlation, Helm UI Updates, Acknowledging Situations

It's time for This Week in OpenNMS!

Last week worked on a bunch more Horizon 23 prep, correlation engine
improvements, Helm UI updates, alarm/situation acknowledgements, and
much more.

    *Internals, APIs, and Documentation*

      o I made some fixes for handling the output of newer JDKs.
      o Jesse worked on a JVM datasource for the correlation engine.
      o Christian did some fixes to timeouts in VMware vCenter handling.
      o Markus and Dustin did more work on the single-port Netflow feature.
      o Matthew added timestamp metadata and weights to vertex
        information generated by the correlation engine.
      o David added support for cascading acknowledgements between
        situations and alarms (and vice-versa).
      o Antonio continued to work on refactoring the Enlinkd codebase.
      o Chandra added timestamps to situation metadata.
      o Chandra continued his work on supporting threshold alarms in
        correlation.
      o Sebastian did more work on improving daemon reload handling.
      o Jesse continued his work on creating a version-agnostic
        integration API.
      o Chandra worked on making sure SASL authentication works with
        Kafka on Minions and Sentinel.
      o Matthew did some work investigating the use of a graph database
        for the OCE cluster engine.
      o I did some work on handling flapping tests better in our Bamboo
        integration test runs.
      o I refactored the Minion and Sentinel assemblies to use a shared
        init script.
  *

    *Web & UI*

      o I worked on handling node template variables in the Alarm Table
        panel in Helm.
      o Patrick worked on performance improvements in the topology UI.
      o Ronny made some UI improvements to the dashboards provided by Helm.
      o Christian did some more work on situation integration in the
        OpenNMS alarm browser.
      o I added support for multi-select variables in the Helm Alarm
        Table panel.
      o David worked on some alarm query improvements in the ReSTv2
        interface.
      o Ronny worked on creating some views to ease report generation.
