OpenNMS On the Horizon – August 1st, 2022

It's time once again for OpenNMS On the Horizon.

Since last time, we worked on documentation (Kafka, Karaf features, MySQL JDBC and JIRA ticketing, and SNMP varbinds), Horizon Stream (Prometheus and Grafana integration, Minion, Skaffold, notifications, and device APIs), CircleCI, Enlinkd bridge topology, ALEC Hellinger Distance, JUnit and test updates, datachoices telemetry, flow persistence in OIA, Newts Cassandra updates, Grafana database reports, cloud APIs, MySQL collection, Spring, OpenTelemetry, and password updates.

• Alex and Thomas worked on database, event, flow, metric, OIA, and polling stats for the datachoices telemetry.
• Dustin did some work on flow persistence support in the OIA plugin API.
• Dino updated a number of places in the documentation to suggest using the featuresBoot.d folder rather than editing Karaf .cfg files directly.
• Jesse did more work on modernizing the Cassandra driver used in Newts.
• I fixed a bug in the Grafana report backend that didn't handle some Grafana 8+ dashboards properly.
• Yang Li worked on integrating Prometheus and Grafana into the Horizon Stream dev environment.

• Antonio made some changes to collection priority scheduling in Enlinkd.
• DJ continued his work to move to OpenTelemetry for tracing.

Web, REST, UI, and Helm

• Mike Rose worked on device GraphQL and display in Horizon Stream.
• Chinh Le did more work on the device UI in Stream.
• Lars did some final refactoring on his password complexity changes.
• Thomas made some fixes to query parameter escaping related to recent advanced search changes.

Coming Soon: JIRA Migration

We will be migrating our JIRA issue-tracker from a self-hosted version to Atlassian's cloud version.
I don't have a timeline for this yet, but expect it in the coming months.

If you currently have an account at the OpenNMS issue tracker your account should already be migrated to JIRA Cloud, but you will need to perform a password reset with the "Can't log in?" link before you can log in.

Releases and Roadmap

Upcoming August Releases

OpenNMS is on a monthly release schedule, with releases happening on the second Wednesday of the month.

The next OpenNMS release day is August 10th, 2022.

We currently expect updates to Horizon 30 and all supported Meridians.

Next Horizon: 31 (Q4 2022)

The next major Horizon release will be Horizon 31.

Since Horizon 30 was only recently released, there is nothing concrete on the roadmap for Horizon 31 yet.
Stay tuned for details when they come.

Next Meridian: 2023 (Q1 2023)

Meridian 2023 is still reasonably early in its development cycle, but you can expect it to contain, at the very least, the work that's going into Horizon 30.
