This Week in OpenNMS: July 17th, 2017

It's time for This Week in OpenNMS! In the last week we worked on
various internals and web code.



      Github Project Updates

  * *Internals, APIs, and Documentation
    *

      * Jesse fixed maskelement matches for events
      * Jesse worked on a project to provide alarm correlation
      * Seth worked on upgrading Karaf to 4.1
      * Ronny worked on AsciiBinder documentation infrastructure
      * Alejandro fixed varbind matching of events

  * *Web and UI
    *

      * Seth did more work on alarm endpoints in the ReSTv2 API
      * Alejandro made it possible to associate foreign sources and IDs
        with events sent through ReST
      * Markus worked on a bunch of BSM and topology issues
      * Dustin worked on GraphML topology status propagation
      * Markus worked on OSGi ReST support
      * Markus made an outage-based node status calculator
      * I added support for ack/unack/escalate/clear of alarms in OpenNMS.js
      * Jesse added support for handling alarm sticky and journal memos
        to OpenNMS.js, and added support for displaying them in Grafana


      OpenNMS Horizon 20.0.1 (Korben Dallas
      <http://fifth-element.wikia.com/wiki/Korben_Dallas>) Released

    OpenNMS Horizon 20.0.1 was released last Monday. It contains fixes
    for number of bugs introduced in 20 including a deadlock in polling.

    For a complete list of what was changed, see the release notes:

      Dev-Jam 2017

    Dev-Jam 2017

    While I am writing this TWiO, Tarus and Jesse are introducing
    Dev-Jam 2017 at Concordia University in Montréal, Canada. Dev-Jam is
    our yearly OpenNMS un-conference where everyone gets a chance to
    socializer and to work on their own personal OpenNMS projects.

    This morning everyone introduced themselves and talked about what
    they planned on doing:

      * updating packaging (yum/Debian) infrastructure including better
        support of upstream PostgreSQL packages
      * improved wifi link support in Enlinkd and topology
      * improving the opennms.com and opennms.org web sites
      * simplifying collection of OCAs
      * integrating DigitalOcean and Xen requisition tools
      * Spark chat integration
      * ReST infrastructure improvements
      * discussing how to improve Docker image generation
      * grafana dashboard for UPS data
      * northbound interfaces for Drools (scriptd-like interface for Alarms)
      * a structured data monitor (using the XML collector infrastructure)
      * Cisco ACI integration
      * OSGi deployment of ReST services
      * donut charts on the front page
      * rewrite the node list page
      * migrate documentation to AsciiBinder
      * trigger IFTTT events when alarms change
      * porting the Go version of the minion to a new platform

    Obviously not all of this will get done in a week, but there are
    lots of neat things going on. Stay tuned for cool new features in
    OpenNMS Horizon 21.0.0!

    Also, Jessica handed out this year's t-shirt, with an awesome design:
