This Week in OpenNMS - November 26th, 2018 - Correlation, Topology, and UI Refactoring

It's time for This Week in OpenNMS!

In the last week we did a lot of OCE work, continued refactoring of topology APIs, did more UI refactoring, and a bunch of other stuff.

Github Project Updates

  • Internals, APIs, and Documentation

    • David Hustace made some enhancements to thresholding events.
    • Will Keaney made some fixes for EIF decoding.
    • Matt worked on graph persistence in OCE.
    • Christian made a convenience method on $OPENNMS_HOME/bin/opennms to ssh to the Karaf console.
    • David Smith worked on making old alarms un-acknowledge situations if they get correlated.
    • David Hustace worked on documenting Thresholding.
    • David Smith fixed situations so they always reference the latest version of an alarm.
    • Chandra worked on detector support in the OpenNMS Integration API.
    • Antonio continued his work on refactoring Enlinkd and topology services.
    • Brynjar Eide fixed the node availability report to honor time zones properly.
    • Matt worked on converting a number of OCE-related objects to be immutable.
    • Matt added support for tagging interface threshold alarms in OCE, and made correlation of SNMP interface poller alarms possible.
  • Web & UI

    • Markus and Sebastian continued the work on creating a Daemon ReST service.
    • Markus did more work porting our Vaadin UI to Vaadin 8.
    • Christian added select/deselect all checkmarks to the scheduled outages page.
    • Sebastian did some work on the Bootstrap 4 UI refactor.
    • Patrick did more work on improving topology UI performance.
