PRE-REQUISITES:
1 - SUSE Observability cluster with an exposed OpenTelemetry Collector ingress endpoint.
2 - OpenTelemetry collector installed on SUSE virtualization cluster (>=1.7.x).
3 - Kube-OVN Operator (Experimental) on SUSE virtualization, Refer : [https://docs.harvesterhci.io/v1.8/advanced/addons/kubeovn-operator](https://docs.harvesterhci.io/v1.8/advanced/addons/kubeovn-operator)
PROCEDURE:
Kube-OVN exposes metrics through its own services in the `kube-system` namespace. These need to be scraped and forwarded to SUSE Observability via the OpenTelemetry collector. For example.
`http://kube-ovn-controller.kube-system.svc:10660/metrics `
`http://kube-ovn-monitor.kube-system.svc:10661/metrics `
`http://kube-ovn-cni.kube-system.svc:10665/metrics `
`http://kube-ovn-pinger.kube-system.svc:8080/metrics`
We need to install OpenTelemetry collector on SUSE Virtualization cluster. Deploy the OpenTelemetry Collector to Scrape Kube-OVN Metrics.
Add the Helm Repository and create Namespace.
`helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts`
`helm repo update`
`kubectl create namespace open-telemetry`
The OTel collector uses bearer token authentication when sending data to SUSE Observability. To create TOKEN refer [https://documentation.suse.com/cloudnative/suse-observability/latest/en/setup/otel/getting-started/getting-started-k8s-operator.html#\_create\_a\_service\_token](https://documentation.suse.com/cloudnative/suse-observability/latest/en/setup/otel/getting-started/getting-started-k8s-operator.html#_create_a_service_token).
Store your service token as a Kubernetes secret: Create the API Key Secret.
`kubectl create secret generic suse-observability-api-key --from-literal=API_KEY= -n open-telemetry`
Create the Helm Values File

Install the Otel Collector
`helm upgrade --install opentelemetry-collector open-telemetry/opentelemetry-collector --values otel-kubeovn-values.yaml`
Verify the logs.
`kubectl -n open-telemetry logs opentelemetry-collector-58f95f7896-64hh6 -f`

Verify Metrics in SUSE Observability
Navigate to **Metrics** in the SUSE Observability UI and search for `kube_ovn_`
Successful ingestion confirms that Kube-OVN metrics are being collected and forwarded to SUSE Observability.
### Visualizing Kube-OVN Metrics in SUSE Observability
After the OpenTelemetry Collector has been configured and Kube-OVN metrics are successfully flowing into SUSE Observability, you can create a custom dashboard to monitor the health and performance of the Kube-OVN networking stack.
#### Create a New Dashboard
1. Log in to SUSE Observability.
2. Navigate to **Dashboards**.
3. Select **Create Dashboard**.
4. Once Dashboard created, Add widget into dashboard.
If you want to see total subnet created in kube-OVN use below query.
`sum(kube_ovn_logical_switch_ports_num) by (logical_switch_name)`
`Some of the sample queries listed below.`
`Virtual Machine RX and TX Traffic per Interface`
`sum(delta(kube_ovn_interface_rx_bytes[5m])) by (interfaceName) `
`sum(delta(kube_ovn_interface_tx_bytes[5m])) by (interfaceName)`
`Logical Switch Port Count`
`kube_ovn_logical_switch_ports_num`
`Virtual Machine RX TX Dropped Packets (errors)`
`sum(delta(kube_ovn_interface_rx_dropped[5m])) by (interfaceName)`
`sum(delta(kube_ovn_interface_tx_dropped[5m])) by (interfaceName)`
`Total Active VM Interfaces`
`count(kube_ovn_interface_rx_packets > 0)`
`DNS Latency`
`(sum(delta(pinger_internal_dns_latency_ms_sum[5m])) by (nodeName))`
`/`
`(sum(delta(pinger_internal_dns_latency_ms_count[5m])) by (nodeName))`
An example Kube-OVN dashboard:
