[Release] – OpenNMS Horizon 18.0.0

We welcome our new release of OpenNMS Horizon 18.0.0 with code name Tardigrade, named after a perhaps one of the most durable known organisms. This release introduces a few really cool new features.

Business Service Monitoring

To be able to get your monitored assets into Business Service related context the “Business Service Monitoring (BSM)” can be used. The goal of the Business Service Monitor is to provide a high-level correlation of business rules, and to display them in the topology map. In the BSM, you define a Business Service that encompasses a set of entities (nodes, interfaces, services, and other Business Services) and the relationships among them. The alarm states of the component entities are rolled up in a map-reduce fashion to drive a state machine. The state of a Business Service is reflected in a new type of event, and can also be visualized (along with the service hierarchy) in the existing OpenNMS topology map. A Business Service can create his own Alarms which can be used in workflows. The graph representation allows to analyze the root cause from the BSM to the technical service and the other way around – which Business Service is impacted by a specific technical service outage.

For details on using the BSM, see the User and Administrators Guide.

ElasticSearch 1.x Event Forwarder

We have added the possibility to forward OpenNMS Events and Alarms into ElasticSearch for analyzing and plotting with other tools like Kibana or Grafana. For more details see the Admin Guide. Big thank you to our community contributor Umberto Nicoletti started this thing.

OpenNMS Properties are modular

Now most properties set in the opennms.properties file can be instead overriden by creating a file in the ${OPENNMS_HOME}/etc/opennms.properties.d directory. It makes it maintenance friendlier and makes it easier to use configuration management tools like SaltStack, Ansible, Chef or Puppet.

Notification for Slack and Mattermost

With the new notification strategies it is now possible to send monitoring notifications to Slack and Mattermost.

OpenNMS Plugin Manager

An API for adding 3rd-party “plugins” to OpenNMS. The core of a tool for adding plugins into OpenNMS has been included in Horizon 18. This provides a set of tools for finding and adding plugins to be loaded into the OpenNMS OSGi container.

Requisition UI improvements

A huge number of improvements have gone into the requisition UI. Also, the old “Quick-Add Node” functionality has been reimplemented using the same backend as the requisition UI.

“Scan Report” Remote Poller GUI

A new front-end for the remote poller that lets you perform a single scan and get a pass/fail report in a GUI has been added. You can enable this alternate UI with the “-s” option on the remote poller CLI.

Topology UI Updates

As part of the BSM work, the topology UI has been vastly improved for both performance and usability.

TSRM Ticketing Plugin

We have added a new Ticketing Plugin for IBM Tivoli Service Request Manager (TSRM).
Information on configuring the TSRM ticketing plugin can be found in the Administrators Guide.

Collect anonymous usage statistics

To get a better idea of how to estimate hardware requirements and the performance characteristics of OpenNMS, we wrote a tool to occasionally submit anonymous diagnostic information about your OpenNMS install. It will submit information like the number of nodes, alarms, etc. as well as some basic system information to our servers for statistical reasons.

When a user with the Admin role logs into the system for the first time, they will be prompted as to whether or not they want to opt-in to publish these statistics. Statistics will only be published once an Administrator has opted-in.
These statistics are visualized on stats.opennms.org.

OpenNMS Data Source is Grafana 3 compliant

We have uploaded the OpenNMS Data Source to Grafana Plugin Platform which allows now easy setup and install with a simple sudo grafana-cli plugins install opennms-datasource.

Vagrant Boxes Refreshed

We have updated the Vagrant boxes which are uploaded to the Atlas Platform. They are updated with latest Horizon 18 and pre-configured Grafana 3 as a test, dev or play environment.

Beside that there are lot of bugs fixed and you can find all of it more detailed in our Release Note.

Happy Updating and Thank you to all contributors to make this great release happen.
