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.
