Role required: discovery\_admin. ## About this task If you use a service mesh, a pod running on every node \(Informer\) communicates with a Prometheus server to get the traffic information. For more information, see [Install Kubernetes Visibility Agent \(KVA\) Informer](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/cnov-deploy-install.md) ## Procedure - Set parameters either during Helm chart archive installation or by modifying the Kubernetes YAML file provided by ServiceNow.
Method Actions
**During Helm installation** In the `Helm install` command, add the following parameter: ``` --set connectionsDiscovery.method= ``` where <METHOD> is the URL for either Istio \(http://prometheus.istio-system:9090\) or Linkerd \(http://prometheus.linkerd-viz:9090\). **Note:** If your Prometheus server URL is not the default one, use the following parameter: ``` --set connectionsDiscovery.prometheusUrl ```
**Modify the `k8s_informer.yaml` script** 1. Access the `k8s_informer.yaml` script. 2. Set the environment variable *k8s\_informer.yaml* by entering either Istio or Linkerd in quotation marks: ``` -- name: GET_CONNECTIONS_METHOD value: "" ``` 3. Run the following command: ``` kubectl apply -f k8s_informer.yaml ```
