onos-kpimon

The xApplication for ONOS SD-RAN (µONOS Architecture) to monitor KPI

Overview

The onos-kpimon is the xApplication running over ONOS SD-RAN to monitor the KPI. onos-kpimon collects KPIs reported by E2 nodes through the KPM service model version 2.0. Since ONOS SD-RAN has multiple micro-services running on the Kubernetes platform, onos-kpimon should run on the Kubernetes along with the other ONOS SD-RAN micro-services. In order to deploy onos-kpimon on the Kubernetes, a Helm chart is necessary, which is in the sdran-helm-charts repository. Note that this application should be running together with the other SD-RAN micro-services, such as Atomix, onos-operator, onos-e2t, onos-uenib, onos-topo, and onos-cli). Easily, sd-ran umbrella chart can be used to deploy all essential micro-services and onos-kpimon.

Interaction with the other ONOS SD-RAN micro-services

To begin with, onos-kpimon makes a subscription with E2 nodes connected to onos-e2t through onos-topo based ONOS xApplication SDK. Creating a subscription, onos-kpimon sets report interval and granularity period which are the monitoring interval parameters. Once the subscription is done successfully, each E2 node starts sending indication messages periodically to report KPIs to onos-kpimon. Then, onos-kpimon decodes each indication message that has KPI monitoring reports and store them to both KPIMON local store, or onos-uenib. A user can check the stored monitoring results through onos-cli as below. Also, if Prometheus and Grafana are enabled, the user can see the stored monitoring results through Grafana dashboard or Prometheus web GUI.

Command Line Interface

Go to the onos-cli, and command below:

$ onos kpimon list metrics
