This Week in OpenNMS - January 14th, 2019 - Correlation, Kafka, Syslog, Docker, and more!

It's time for This Week in OpenNMS!

Last week we did more alarm correlation updates, lots of Kafka fixes and enhancements, worked on a new SNMP collector, and did a lot of other smaller changes.

Github Project Updates

  • Internals, APIs, and Documentation

    • Jesse worked on handling clock skew when triggering alarms in Alarmd.
    • Matt worked on making it possible for the integration API to handle situation feedback without Kafka.
    • Antonio continued his work to publish topology data to Kafka.
    • Patrick started work on a new SnmpCollector that works with Minions.
    • Chandra did more work on handling caching/large buffer sizes in Kafka RPC.
    • I did some more fixes to my opennms shell refactor.
    • I worked on attempting to update to a newer version of HikariCP.
    • Matt added support for optionally attaching the raw syslog message to Syslogd-generated events.
    • Ronny worked on refactoring/replacing our Docker test images.
  • Web & UI

    • I fixed some issues in the group-by-node portion of Helm's alarm details tab.

Until Next Week…

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