OpenNMS On the Horizon – August 5th, 2019 – Updating Dependencies, Fixing Bugs, Enhancing Flows and Reporting, Helm Improvements

In the last week we did a ton of work modernizing some dependencies in OpenNMS and Helm, fixed a bunch of bugs, and continued work to enhance flows reporting, and UIs on the road to Horizon 25.

Github Project Updates

• Internals, APIs, and Documentation
  • Matt continued his work on persisting threshold state to the database and sharing that state across Sentinels.
  • Jesse worked on wrapping up his high-performance DNS hostname resolution integration.
  • Chandra finished some changes to Kafka initialization settings.
  • Jesse updated the Elasticsearch integration so you can set a prefix, allowing multiple “namespaces” for data persisted to ES.
  • Ronny wrapped up his work to make our continuous integration containers run as non-root. He also made it so branch builds can be tagged in CI for release to dockerhub.
  • Jesse updated our Elasticsearch support to ES 7.2.0. Note that Horizon 25 (and Meridian 2019) will require ElasticSearch 7.
  • Chandra continued his work on an optimized off-heap storage on the Minion (to replace H2).
  • Christian added support for %interface% and %interfaceresolve% on node events, using the primary IP when available.
  • I fixed an issue with find-java.sh failing when java is behind multiple levels of symlinks.
  • Alejandro updated the NXOS GPB parser to provide more info on configuring the Nexus switch to work with it.
  • Jesse fixed the snmphost mask in clogMessageDiscarded in the default eventconf.
  • Sean did more work on improving our CircleCI workflow.
  • Ron Roskens continued to work on getting the build and tests running under JDK 11.
  • Justin Wood contributed a patch to fix provision:show-import when using the DNS importer.
  • Jesse updated our embedded Drools to 7.24.
  • Chandra worked on adding support for “profiles” when attempting to connect to new SNMP hosts.
  • Sean contributed an update to Jaeger tracing with current thread info in the Camel and Kafka IPC bits.
• Web, ReST, and UI
  • Markus did more work on simplifying the UI for scheduling reports.
  • Patrick updated his branch to make flow classification rule priority customizable.
  • I fixed some issues with DAOs and property caching in OpenNMS.js.
  • I cleaned up some authorization-management code in OpenNMS.js after the recent refactor.
  • I updated OpenNMS.js to use dependabot to update dependencies semi-automatically.
  • Christian fixed a bug with displaying headers in Vaadin apps when embedded in an <iframe> tag.
  • I added support for configuring alignment (left, center, right) in Helm Alarm Table columns.

Upcoming Events and Appearances

• All Things Open in Raleigh, NC - October 13th through 15th
  Tarus Balog will be speaking at All Things Open again this year. It’s a wonderful open-source conference here in the back yard of The OpenNMS Group’s offices.

  The speaking schedule is still to be determined.

• NETHINKS Training in Fulda, Germany - October 21st through 25th

  NETHINKS will be offering German-language training in their headquarters in Fulda, Germany the week of October 21st.

• OSMC 2019 in Nuremberg, Germany - November 4th through 7th
  We will be at OSMC in November.

  There will be a 1-day workshop on November 4th, focusing on getting started with OpenNMS including notifications, alarms, and graphing in Grafana with Helm.

  For more information on OSMC, see their website. Details on the workshop and a link to purchase tickets are available on their workshops page.

Until Next Week…

If there’s anything you’d like me to talk about in a future OOH, or you just have a comment or criticism you’d like to share, don’t hesitate to say hi.
