OpenNMS Helm - PM/FM Console for Grafana CircleCI

Helm is a Grafana application that allows users to create flexible dashboards using both fault management (FM) and performance management (PM) data from OpenNMS® Horizon™ and/or OpenNMS® Meridian™.

It is the successor to the original OpenNMS Datasource for Grafana.

Consult the Helm Documentation for help on installing, configuring and using the application.


Fault Management (FM)

Flexible alarm filtering

Isolate the alarms you want displayed using custom filters and conditions that can match against over 150 different fields.

Configurable displays

Present the fields that are most relevant to you and your teams for improved tracking and triage.

Alarm interactions

Acknowledge, escalate and create tickets for alarms directly from the dashboard.

Performance Management (PM)

Storage engine agnostic

Retrieve metrics stored in any of the available persistence engines i.e. rrdtool, JRobin and Newts.

Template support

Populate template variables with all of the nodes belonging to a set of categories, or leverage the complete filter grammar.

Trending and Forecasting

Remove outliers and perform trending or forecasting using the built-in series filters. Develop your own filters using Java or R.

Derive new series using JEXL expressions.
