OpenNMS On the Horizon - February 18th, 2020 - Flows, Time-Series, Graph API, Karaf, Helm, SNMPv3, Search, and More!

It’s time for OpenNMS On the Horizon!

In the last week we worked on flows, the time-series and graph APIs, the Karaf CLI, Helm, SNMPv3, web search, and more!

Github Project Updates

Internals, APIs, and Documentation

  • Patrick continued his work on a new time-series API.
  • Christian did more work on flow ingress/egress tagging.
  • Jesse continued working on moving all Karaf commands into an opennms prefix and cleaning up naming.
  • Markus did more work on enhancing flow rule classification configuration.
  • Markus continued his work on integrating the new graph service into OIA.
  • Ronny and I did more work on updating Helm’s workflows in CircleCI.
  • Ronny updated the documentation to include the new options for downtime model handling.
  • Marcel made an enhancement to the data provided by a nodeAdded event.
  • Marcel updated the documentation to include information on the config tester.
  • Chandra worked on improving SNMPv3 support to have a persistent engine ID.

Web, ReST, and UI

  • I wrapped up some release changes for Helm.
  • Christian fixed a bug in serializing ID and IP interface in the ifservices ReST endpoint.
  • Markus did some more work on a universal search web interface.

Helm 5

Last week we released Helm 5, our custom plugin for Grafana.

Helm 5 fixes a number of issues, most notably compatibility with newer Grafana releases. These fixes necessitated dropping compatibility with Grafana versions older than 6.3, so we have bumped the major version of Helm to 5.

Additionally, documentation has been improved and a number of behind-the-scenes changes have been made related to continuous integration and build system.

DockerHub Changes

Ronny pointed out on Discourse that as of Horizon 25, our Docker images are automatically generated from tagged releases in opennms/horizon on DockerHub. Old images that used to reside in the opennms/horizon-core-web DockerHub project have been moved into the new location.

If you have old docker-compose.yml files or K8s deployments that use the old URLs, please migrate them.

Wiki Migration

Marcel has started a project to migrate (and update!) old and outdated wiki pages to Discourse.

If you’d like to help, please check out the discussion and join in the “fun”.
