Pinger makes network requests between pods/nodes/services/dns to test the connectivity in the cluster and expose metrics in Prometheus format.
Kube-OVN will expose metrics of its own components and network quality. All exposed metrics can be found here.
You can use kube-prometheus to scrape the metrics. The related ServiceMonitor yaml can be found here.
