Dev-Jam 2019

Introducing Dev-Jam

Dev-Jam is our annual hackathon and developer conference where the OpenNMS Group, the Order of the Green Polo, and other OpenNMS contributors join each other in one place and work on whatever project tickles our fancy.

This Year at Dev-Jam

This year we were again at the University of Minnesota’s Minneapolis campus.

On Monday, some folks did presentations to launch Dev-Jam, including catching up on the last year of OpenNMS changes, tips on getting started with OpenNMS development, and more. Then we settled in for a week of hacking on code, socializing, and generally having a great time. On Friday, many folks gave presentations on what they worked on for the week.

If you want a feel for what the day-to-day is like during Dev-Jam, our CEO Tarus has been chronicling it on his blog starting at day 0 (Sunday night).

Projects

People worked on all kinds of projects, including but not limited to:

  • finishing a years-long refactor of the database infrastructure in our integration tests
  • modernizing OpenNMS Compass’s build infrastructure and backend code to use OpenNMS.js
  • sending Kubernetes events to OpenNMS
  • integrating PRIS into the OpenNMS core as a Karaf/OIA plugin
  • an Alexa skill for querying alarms and outages from OpenNMS
  • a demo of the MQTT plugin integration
  • a visualization framework for topology and alarms using GL and VR
  • a new “spotlight” search bar that searches nodes, alarms, categories, and more
  • massive performance improvements to ALEC processing
  • a tool for evaluating configuration changes to aid in upgrading
  • CircleCI performance improvements to bring the pipeline time down to a couple of hours
  • a Cisco APIC controller plugin for importing inventory and receiving faults as events
  • building and running tests under OpenJDK 11

Most of the projects had Friday video presentations, and we will work to get those out to you soon.

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.
