OpenNMS On the Horizon – June 17th, 2019 – Flow Hostname Resolution, Helm and UI Enhancements, and More!

It’s time for OpenNMS On the Horizon!

Sorry I missed one, I am pretty sure I wrote it but left it in a tab and never hit “save” or something. ¯\_(ツ)_/¯

In the last two weeks we worked on a number of flow-related changes including bug fixing, resolving hostnames, and new Helm features. We also worked on a number of other UI enhancements relating to topology graphs, reporting, and authentication.

Github Project Updates

  • Internals, APIs, and Documentation
    • Christian worked on some fixes to Netflow 9 value scaling.
    • Chandra did more work on sending events from Minions.
    • Matt worked on adding search support to the new graph service.
    • Dustin and Christian continued to work on adding hostname resolution during flow processing.
    • Ronny and Jesse worked on CircleCI and test environment changes.
    • Chandra started work on supporting moving a (provisioned) node to a new location.
  • Web, ReST, and UI
    • Matt wrapped up his changes to add flow conversation, application, and host queries to OpenNMS.js and Helm.
    • Markus worked on rewriting the reporting UI in Angular.
    • Markus worked on adding support for generating reports from Grafana dashboards.
    • Markus fixed some issues with 401 authentication handling in Angular-based apps in the web UI.
    • Matt created a new histogram panel to Helm.
    • I updated a number of dependencies in OpenNMS.js and Helm to fix security alerts.
    • Markus worked on a UI to interact with Matt’s graph service search API.
    • Christian fixed a bug that would keep services with slashes in their name from showing timelines in the node detail page.
    • I worked on refactoring the experimental inventory datasource with the faults datasource into a new entity datasource.
    • Chandra worked on making the web UI graph page lazy-load graphs as well as support searching.

Upcoming Events and Appearances

Until Next Week…

If there’s anything you’d like me to talk about in a future OOH, or you just have a comment or criticism you’d like to share, don’t hesitate to say hi.
