Monitor and Dashboard¶

Kube-OVN can export network control plane information and network data plane quality information metrics to the external in formats supported by Prometheus.

We use the CRD provided by kube-prometheus to define the corresponding Prometheus monitoring rules. For all monitoring metrics supported by Kube-OVN, please refer to Kube-OVN Monitoring Metrics.

If you are using native Prometheus, please refer to Configuring Native Prometheus for configuration.

Install Prometheus Monitor¶

Kube-OVN uses Prometheus Monitor CRD to manage the monitoring output.

# network quality related monitoring metrics
kubectl apply -f https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/pinger-monitor.yaml
# kube-ovn-controller metrics
kubectl apply -f https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/controller-monitor.yaml
# kube-ovn-cni metrics
kubectl apply -f https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/cni-monitor.yaml
# ovn metrics
kubectl apply -f https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/ovn-monitor.yaml

The default interval for Prometheus pull is 15s, if you need to adjust it, modify the interval value in yaml.

Import Grafana Dashboard¶

Kube-OVN provides a predefined Grafana Dashboard to display control plane and data plane related metrics.

Download the corresponding Dashboard template:

# network quality related monitoring dashboard
wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/pinger-grafana.json
# kube-ovn-controller dashboard
wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/controller-grafana.json
# kube-ovn-cni dashboard
wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/cni-grafana.json
# ovn dashboard
wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/ovn-grafana.json
# ovs dashboard
wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/monitoring/ovs-grafana.json

Import these templates into Grafana and set the data source to the corresponding Prometheus to see the following Dashboards.
