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

It’s time for OpenNMS On the Horizon!

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

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.
