OpenNMS Plugin for Grafana

OpenNMS Plugin for Grafana (formerly known as Helm) is a Grafana application that allows users to create flexible monitoring dashboards using data from OpenNMS® Horizon™ and/or OpenNMS® Meridian™.

Supported data:

• Performance and response time (time series metrics)
• Fault (alarms and outages)
• Inventory (nodes, IP & SNMP interfaces, services)
• NetFlow (NetFlow v5 & v9, IPFIX, sFlow)

For help on installing, configuring, and using the application, read the documentation.

Features

Flexible data filtering

Isolate the data you want to display using custom filters and conditions. The filter panel goes a step further—enabling global data filtering for your dashboard.

Configurable displays

Present fields that are most relevant to you and your teams to improve tracking and triage.

Alarm interactions

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

Storage engine agnostic

Retrieve time series metrics stored in persistence engines, including OpenNMS Time Series DB, Newts, Cortex, RRDtool, or JRobin.

Flows deep-dive dashboard

This custom dashboard, included in the app, provides a powerful, flexible interface for exploring NetFlow data alongside performance metrics.

Template support

Populate template variables with query results from any of the included OpenNMS data source plugins.

Trending and forecasting of time series data

Remove outliers and perform trending or forecasting using the built-in series filters or develop your own filters using Java or R. Derive new series using JEXL expressions.
