It's time for This Week in OpenNMS!
Last week we mostly worked on wrapping up various in-progress projects.
<#github-project-updates>Github Project Updates
*
*Internals, APIs, and Documentation*
o David Hustace did some final cleanup to his updated alarm
workflow code.
o Matthew did some work work on leader election in Sentinel
containers.
o Chandra made some more adjustments to his work on Karaf commands
to reload daemons.
o Matthew extended the Kafka producer to be able to expose
information on situations.
o Dustin continued his work on using a single port for receiving
multiple netflow protocols.
*
*Web & UI*
o Christian added the polling interval to the service status UI.
o I fixed the minion status page to show |unknown| status for
minions that do not have an associated node.
o David added additional situation-related features to the ReST v2
alarm API.
o I updated the minion status page to link to the related node if
there is one.
<#meridian-201810-released>Meridian
<https://www.opennms.com/meridian/> 2018.1.0 Released
I don't normally go into too much detail on the .com side of things
since TWiO is about the open source project for the most part, but it's
the one time of year where we make a significant announcement. (Sorry,
no tote bags.)
Last week we released Meridian 2018.1.0
<https://www.opennms.com/2018/09/06/opennms-meridian-2018-1-0-released/>,
the first release in the 2018 series. Like all Meridian releases, it
will be supported with bugfixes and security updates for 3 years. Note
that this means Meridian 2015 support ends at the end of this calendar year.
Meridian <https://www.opennms.com/meridian/> 2018 is based on OpenNMS
Horizon 21 plus a few other changes and bugfixes that went into Horizon 22.
The most significant addition in Meridian 2018 is official support for
the Minion.
Other new features include:
* *IBM Tivoli Event Integration Facility
<https://meridian.opennms.com/docs/2018/latest/guide-admin/index.html#ga-events-sources-eif>*:
Support has been added to bridge EIF events into OpenNMS.
* *Asset Topology Provider
<https://meridian.opennms.com/docs/2018/latest/guide-admin/index.html#_asset_topology_provider>*:
The Asset Topology Provider generates a GraphML topology based on
node metadata including asset fields.
* *Alarm Sounds
<https://meridian.opennms.com/docs/2018/latest/guide-admin/index.html#ga-alarm-sounds>*:
The web UI can now optionally flash and play an alert sound when
alarms are created and optionally updated.
* *ReST Updates*: A new experimental ReST API (/opennms/api/v2) has
been enabled which supports JEXL 2.x
<https://commons.apache.org/proper/commons-jexl/>.
* *Topology UI*: The topology UI now supports scriptable vertex status
<https://meridian.opennms.com/docs/2018/latest/guide-development/index.html#gd-topology-graphml-vertex-status-provider>.
* **Alarm Northbounders <https://issues.opennms.org/browse/NMS-9513>:
There are new alarm northbounders for running arbitrary BSF scripts
or forwarding to Drools.
* *Web UI*: It is now possible to customize the date format
<https://issues.opennms.org/browse/NMS-10072> used in the UI. You
can configure it by overriding the |org.opennms.ui.datettimeformat|
property in |opennms.properties|.
* *Hawtio*: Hawtio is now included as an optional webapp package
(|opennms-webapp-hawtio|) for convenience.
* *IFTTT*: Support has been added for triggering IFTTT events based on
alarms.
On top of that, there have been many smaller improvements and
enhancements since Meridian 2017. If you follow TWiO regularly, you've
probably already read about them when they arrived in Horizon releases. ;)
