 1. Before you can configure Sumo Logic to ingest metrics, you must enable the Prometheus metrics in the Nginx Ingress controller and annotate the Nginx Ingress pods, so Prometheus can find the Nginx Ingress metrics. For instructions on Nginx Open Source, refer to [this documentation](https://docs.nginx.com/nginx-ingress-controller/logging-and-monitoring/prometheus/).
 2. Ensure you have deployed the [Sumologic-Kubernetes-Collection](https://github.com/SumoLogic/sumologic-kubernetes-collection), to send the logs and metrics to Sumologic. For more information on deploying Sumologic-Kubernetes-Collection, [visit here](/docs/send-data/kubernetes/install-helm-chart). Once deployed, logs will automatically be picked up and sent by default. Prometheus will scrape the Nginx Ingress pods, based on the annotations set in Step 1, for the metrics. Logs and Metrics will automatically be sent to the respective [Sumo Logic Distribution for OpenTelemetry Collector](https://github.com/SumoLogic/sumologic-otel-collector) instances, which consistently tag your logs and metrics, then forward them to your Sumo Logic org.

 ## Installing the Nginx Ingress app
+import AppInstall2 from '../../reuse/apps/app-install-sc-k8s.md';
 
-This section demonstrates how to install the Nginx Ingress app. These instructions assume you have already set up the collection as described above.
-
-To install the app:
-
-Locate and install the app you need from the **App Catalog**. If you want to see a preview of the dashboards included with the app before installing, click **Preview Dashboards**.
-
-1. From the **App Catalog**, search for and select the app.
-2. Select the version of the service you're using and click **Add to Library**.
-3. To install the app, complete the following fields.
-   1. **App Name.** You can retain the existing name, or enter a name of your choice for the app.
-   2. **Data Source.**
-   3. Choose **Enter a Custom Data Filter**, and enter a custom Nginx Ingress farm filter. Examples:
-      1. For all Nginx Ingress farms: `webserver_farm=*`.
-      2. For a specific farm: `webserver_farm=nginx-ingress.dev.01`.
-      3. Farms within a specific environment: `webserver_farm=nginx-ingress.dev.01` and `environment=prod` (This assumes you have set the optional environment tag while configuring collection).
-      4. **Advanced**. Select the **Location in Library** (the default is the Personal folder in the library), or click **New Folder** to add a new folder.
-4. Click **Add to Library**.

-Template variables provide dynamic dashboards that can rescope data on the fly. As you apply variables to troubleshoot through your dashboard, you view dynamic changes to the data for a quicker resolution to the root cause. You can use template variables to drill down and examine the data on a granular level. For more information, see [Filter with template variables](/docs/dashboards/filter-template-variables.md).
