It’s time for This Week in OpenNMS!
Sorry I missed last week, but I was out for a bit and by the time I was back figured I’d just punt to this week.
In the last two weeks we did more work on moving code to using OIA, improved flow persistence, fixed a bunch of alarm bugs, worked on a bunch of code debt, did more topology UI work, and made lots of improvements to Helm.
Github Project Updates
Internals, APIs, and Documentation
- Chandra continued his work on service detector support in OIA.
- Dustin worked on making it possible to use JSR-223 scripting to modify flow data before it is persisted.
- David has been working on adding explicit priority support to events for more predictable ordering.
- Matt worked on being able to send inventory directly to in-JVM OCE without using Kafka.
- Christian added support for transforming nodeId and interface in JEXL when using the
- Jesse worked on optimizing alarm (re)publishing to occur only if
- Christian updated the DHCP service monitor to use dhcp4java.
- Chandra did more work on service monitor support in OIA.
- Jesse continued develpment indexing alarm history in Elasticsearch.
- Dustin worked on tracking flows by application rather than source and destination port.
- Jesse worked on an example set of Drools alarm rules to create “nag” notification events.
- Matt added correlation feedback support to OIA.
- Matt did more work on fixing support for additional syslog formats.
- Christian fixed a bug where
linkDownalarms would not be generated if
- Matt worked on improving performance of alarm snapshotting in the Drools context.
- Patrick started on the thankless job of modernizing the SnmpCollector. (Thanks!)
- Patrick worked on normalizing a number of places where we convert integers from strings.
- Jesse did a number of fixes to improve edge cases and failures in the new alarm handling.
Web & UI
- I did a ton of enhancements to Helm (mostly in the alarm table code) in preparation for a 3.0 release.
- Christian added applications to edges in the BSM topology view.
- Antonio continued his work on a topology ReST service.
- Dustin added support for using the browser notification API for getting notifications.
- Dustin fixed the measurements API to return responses in the same column order as requested.
- Patrick worked on wrapping up his topology performance enhancements.
- Sebastian continued to work on the Bootstrap 4 UI refactor.
As many of you are surely aware, traffic on our e-mail discussion lists has steadily declined for a long time.
People have, for the most part, been moving to other venues for asking questions, and a lot of folks have embraced https://chat.opennms.com/ as a way to get real-time help from other community members.
Thanks to the fine folks at Discourse, we now have a community forum that can hopefully meet the needs of folks who traditionally used the e-mail lists.
I realize it’s no replacement for the oldskool listservs I still hold in my heart, but it at least provides a lot of tools for notifications and replying by e-mail to give some amount of equivalence to the mailing lists.
OpenNMS Holiday Break and Releases
The OpenNMS Group will be on break next week for the holidays, and we will resume normal operations in the new year.
Also, a note: normally we’d do releases on the third Thursday of the month, but this time around that is… the day before we disappear for a week.
So obviously that’s not the greatest idea, and we’ll be skipping this month’s releases.
The next Horizon and Meridian update scheduled is Thursday, January 17th.
I hope everyone has a happy holiday and a good new year!
See you in 2019!
Until Next Week…
