OpenNMS Plugin for Grafana 
OpenNMS Plugin for Grafana is a Grafana application plugin that allows users to create flexible monitoring dashboards using data from OpenNMS® Horizon™ and/or OpenNMS® Meridian™.

- 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.
