OpenNMS On the Horizon – SNMPv3, Dependencies, Kafka Certificates, Flows, CircleCI, Documentation

In the last week we did more changes for SNMPv3 credentials, updated dependencies, Kafka certificate validation, flows, continuous, and documentation.

Github Project Updates

Internals, APIs, and Documentation

• Chandra worked on encrypting stored SNMPv3 credentials.
• I did a number of dependency updates.
• Chandra made Kafka certificate validation configurable.
• Bonnie did more work on documentation for thresholding metadata, and users.
• Sean worked on a fix for the flow "last seen" column not getting updated in raw mode.
• Christian continued his work on moving remote polling functionality to the Minion.
• Jeff added documentation for the snmpTrapAddress varbind, used when processing proxied SNMP traps.
• I updated our CircleCI builds to perform some extra steps to publish documentation, XSDs, and other build output used during releases as artifacts.

Calendar of Events

Upcoming Releases - August 4th, 2020

The next OpenNMS release day is August 4th, 2020.
Currently we expect new bugfix releases from Meridian 2019 and Horizon 26.

Also coming up soon is Horizon 27, hopefully by early fall.
It's going to contain a bunch of great stuff:

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

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.
