It's time for This Week in OpenNMS!

Last week we made improvements to Sentinel, CDP support, correlation
feedback, and more.


    <#github-project-updates>Github Project Updates

  *

    *Internals, APIs, and Documentation*

      o Markus worked on some improvements to the Sentinel container code.
      o David worked on adding additional filtering support to Sextant.
      o Patrick did some performance improvements to CDP topology
        calculation.
      o Jesse fixed JSON collection on the minion.
      o Dustin continued his work to support multiple flow protocols on
        a single UDP port.
      o Matthew worked on high availability and leader election for
        Sentinel containers.
      o Matthew added support for skipping publishing alarm updates to
        Kafka if the change only affects event count or last time.
      o Chandra worked on queueing sink messages to disk until
        communication comes back online.
  *

    *Web & UI*

      o Antonio worked on a ReST service to expose CDP topology.
      o Christian added a button to delete a minion in the minion status UI.
      o I fixed an old regression in the web UI to make "1 day" the
        default graph period again (and made it configurable).
      o David worked on improving alarm and summary data in OpenNMS.js
        and Helm.
      o David also worked on cleaning up and finalizing the alarm
        correlation feedback UI in Helm.
