This Week in OpenNMS: October 10th, 2016

      It's time for This Week in OpenNMS!

In the last week we worked on data collection, Minion, maps, users and
groups, and bug fixes.



      Github Project Updates

  * *Data Collection*

    Alejandro fixed an issue in SNMP counter wrap causing spikes in
    graphs. Ronny added collection configuration for Elasticsearch stats
    (using the XmlCollector). Seth cleaned up a bunch of graph
    definitions. Chandra fixed the JMX Detector to be able to handle
    timeouts properly despite the Java JMX APIs being ancient and unable
    to handle it themselves. (but we’re not bitter…)

  * *Minion*

    Chandra worked on handling locations in SNMP config and fixed an
    issue with Trapd on shutdown. He also worked on exposing
    location-based definitions in provisiond, poller, and ReST. Pradeep
    added more Kafka metrics to be monitored through JMX. I worked on
    cleaning up the Minion assembly and packaging, and making it so
    Minion can run as non-root. Seth worked on renaming
    the |localhost| default location to |Default| to make it less confusing.

  * *Maps*

    I updated our leaflet maps (geomaps) to the latest version of
    leaflet and the markercluster service. Dustin fixed resource graph
    rendering in the topology map info panel.

  * *Users and Groups*

    Alejandro did more work on migrating the info stored
    in |magic-users.properties| to|users.xml| including an upgrade script.

  * *Bug Fixes*

    Seth fixed a regression in 18 that removed the ability to allow
    nodes to be discovered without a default foreign source. Alejandro
    fixed a bug that prevented installation using PostgreSQL 9.6. We’ve
    also been spending time fixing a bunch of smaller bugs and starting
    to identify blockers for 19.0.0, due in the next few months.
