This Week in OpenNMS: May 2nd, 2016

      It's time for This Week in OpenNMS!

In the last week we worked on the BSM, topology maps, Minion, the TSRM
ticketing plugin, JMX data collection configuration, Newts,
Documentation, Requisitions, Compass, and bug fixes.



      Github Project Updates

  * *Business Service Monitor and Topology Maps*

    This week was more of Jesse, Ronny, and Markus wrapping up BSM for
    Horizon 18. Jesse did a ton of performance work on loading Enlinkd
    data into the topology UI, bringing his test set load time down from
    5 minutes down to 5 seconds.

  * *OSGi Updates and Minion*

    Seth spent some time working on various issues related to Karaf —
    updating our embedded Karaf container, as well as more work on
    getting Minion-related code loading.

  * *TSRM Ticketing Plugin*

    Chandra finished wrapping up the IBM TSRM plugin and has merged it
    into the Horizon 18 branch.

  * *JMX Data Collection*

    Jesse updated the JMX data collection configuration to support split
    files in the jmx-datacollection-config.d directory.

  * *Newts and Cassandra Performance Investigation*

    Jesse spent some time investigating a performance issue reported by
    a number of our customers related to Newts and Cassandra. It turns
    out the issue was related to default logging levels and the
    Cassandra driver, and the fix was as simple as adding this to your
    OpenNMS log4j2.xml file:

    <logger name=”com.datastax.driver” additivity=”false” level=”INFO”>
       <appender-ref ref=”RoutingAppender”/>
    </logger>

  * *Documentation*

    Chandra, Seth, Ronny, Jesse, and Sven Reissmann have updated
    documentation in multiple places in preparation for Horizon 18. It
    is also now possible to view the documentation in the “opennms-doc”
    package from the OpenNMS web UI by default.

  * *Requisitions*

    Alejandro has done a bit more cleanup and fixing of the Requisitions
    UI for Horizon 18.

  * *Compass*

    I spent more time this last week cleaning up small things and fixing
    a few bugs in Compass. I also beefed up the (almost nonexistent)
    analytics inside Compass, and added an opt-out for analytics
    tracking. If you’d like to help beta test Compass, see the Compass
    web site: https://compass.opennms.io/#beta

  *

    *Bug Fixes*

    A lot of other minor bug fixes have been going in in preparation for
    OpenNMS Horizon 18.



      OpenNMS Horizon 18 Due Monday, May 9th

Barring any last-minute bugs we may discover in testing, the Horizon 18
branch is finished and our plan is to release next Monday, May 9th. If
you have a test setup, please give the OpenNMS 18 snapshots a try and
let us know if you run into any issues; this is shaping up to be a
really nice release. Just change your yum or apt configuration to use
“snapshot” instead of “stable” and you’ll get the snapshot builds. While
we are prepping 18, “snapshot” points to the release branch, rather than
develop.
