This Week in OpenNMS: April 9th, 2018

It's time for This Week in OpenNMS!

In the last week we released Helm 1.1.0, continued to do more work in
preparation for Drift in Horizon 22, and worked on various integrations
with other tools.


    <#github-project-updates>Github Project Updates

  *

    *Internals, APIs, and Documentation*

      o I fixed a bug that would cause some event comparisons to not
        match properly.
      o Jesse, David, and I fixed some bugs in building on Windows.
      o Jesse fixed an issue with template compatibility across
        different Elasticsearch versions.
      o Chandra did more work on Kafka integration.
      o Christian updated our embedded Karaf to 4.1.5 to fix some Karaf
        shell issues.
      o Jesse refactored our Camel sink implementation.
  *

    *Web & UI*

      o I wrapped up my fixes for Helm and ReST timeouts.
      o I implemented support for fallback attributes (eg, handling
        ifHCInOctets/ifInOctets gracefully) in Helm
      o I fixed a bug in the Helm perf-ds that would cause it to not
        report errors properly on timeout.


    <#opennms-helm-110-released>OpenNMS Helm 1.1.0 Released

A new version of our Grafana integration, OpenNMS Helm, has been
released. It includes a number of bug fixes and features, including
Grafana 5 support as well as support for defining custom actions in the
alarm table panel.

Packages are available in our Debian and RPM repositories, as well as
directly in the Grafana plugin registry.

The DockerHub image for Helm
<https://hub.docker.com/r/opennms/helm/tags/> has been updated as well,
with Helm 1.1.0 and Grafana 5.0.4.
