Apologies for the skipped OOH, I was on vacation last week.

In the last two weeks we worked on documentation, CI, a number of detectors and pollers, flows, meta-data, Helm, and custom resource graphs.

Github Project Updates

Internals, APIs, and Documentation

  • I worked on updating our CI builds to use Cloudsmith for assets
  • I updated the HTTP detector to work with servers that do not send a response reason phrase
  • Christian did more work adding support for setting meta-data in requisitions
  • Dustin worked on improved support for DNS hostname resolution in flow data
  • Bonnie and Ronnie worked on migrating documentation to Antora
  • Alejandro added support for custom.system.properties in the Sentinel Docker image
  • Jeff worked on being able to handle indirect and complex SNMP indices
  • David Schlenk updated some of our WMI bits to support NTLMv2/SMBv2
  • Christian added a fix to handle invalid flow data from some vendor devices
  • Christian fixed VCenter CIM handling on OpenJDK 11

Web, ReST, UI, and Helm

  • I changed the custom resource list to be sorted
  • I did more work on fixing Helm in Grafana 7
  • Chandra made the custom resource graph handle being unable to "graph all" more gracefully

October Releases - Horizon 26.2.2, Meridians 2018.1.23, 2019.1.12, and 2020.1.0

Last week we released Horizon 26.2.2, as well as the latest Meridian 2018, 2019, and 2020.

For a complete rundown of the releases, see the October release announcement.

Release Roadmap

November Releases

The next OpenNMS release day is November 3rd, 2020.

The current plan is to release Horizon 27 as well as Meridians 2019 and 2020.

Next Horizon: 27 (Q4 2020)

The next major Horizon release will be Horizon 27.
It's going to contain a bunch of great stuff:

  • improvements to node caching for flow processing
  • VMware meta-data has been moved from assets to the new node meta-data
  • Minion improvements, including configuration enhancements and an overhaul to RPC thread-handling
  • a new handy global search bar in the web UI
  • improved SNMPv3 auth configuration
  • a major rework of remote poller functionality, now integrated with the Minion (we're calling it Application Perspective Monitoring)

Next Meridian: 2021 (Q2 2021)

With the recent release of Meridian 2020, plans are still tentative.
However, the current expectation is that Meridian 2021 will be based on Horizon 28, which is expected to build on Horizon 27 with additional flow and metadata improvements.

We'll know more once development plans start to firm up.
