It's time for OpenNMS On the Horizon!

In the last week we updated documentation, fixed a number of important bugs, continued to work on topology and classification UI improvements, and more.

Github Project Updates

  • Internals, APIs, and Documentation

    • Ronny worked with Alejandro and Jesse to improve our Newts installation guide to follow more best practice with Schema installation and we have stopped maintaining our own Cassandra installation instructions.
    • Patrick continued his work on refactoring and evaluating our time series APIs.
    • Markus worked on documentation for the new graph service.
    • Dustin fixed some issues with dropped packets on the telemetryd listeners.
    • Jesse fixed some issues with exception handling in OIA.
    • Markus made improvements to the flow classification rule engine to reduce memory usage and to fix port range handling.
    • Chandra updated the SNMP detector to support SNMP profiles.
    • Christian fixed some issues with associating flows with nodes behind NAT.
    • Jesse did more work on the changes to allow flows to balance across Kafka partitions.
    • Markus worked on optimizations in graph view enrichment.
    • I worked on adding support for deleting nodes triggered by the downtime model if only unmanaged interfaces remain.
    • Jesse updated Alarmd processing to use Drools streaming again now that they have fixed upstream bugs.
  • Web, ReST, and UI

    • Markus did more work on adding support for choosing a layer in the topology UI in the URL.
    • Markus fixed the classification UI to report better error messages.
    • Antonio continued his work on enhancements to the topology link provider.

Calendar of Events

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.
