+
+## View your NGINX data in New Relic [#find-data]
+
+Once your setup is complete and data is flowing, you can view your NGINX metrics and logs in New Relic and create custom alerts.
+
+**Method 1: Through Integrations & Agents**
+1. Go to [one.newrelic.com](https://one.newrelic.com) > **Integrations & Agents**
+2. Click **Dashboards**
+3. Find and click **NGINX OTel overview** dashboard
+4. Select your account and click **View dashboard**
+
+**Method 2: Through Infrastructure monitoring**
+1. Go to [one.newrelic.com](https://one.newrelic.com) > **On-host integrations**
+2. Search for your NGINX server by deployment name (e.g., `production-web-01`)
+3. Click on your server to see detailed metrics
+
+## Query your data with NRQL
+
+You can create custom queries to analyze your NGINX data:
+
+**Example queries:**
+
+```sql
+-- View request rate over time
+FROM Metric SELECT rate(sum(nginx.requests), 1 minute)
+WHERE nginx.deployment.name = 'production-web-01'
+TIMESERIES
+
+-- Check connection states
+FROM Metric SELECT latest(nginx.connections_current)
+WHERE nginx.deployment.name = 'production-web-01'
+FACET state
+
+-- Analyze log patterns (if log forwarding enabled)
+FROM Log SELECT count(*)
+WHERE nginx.deployment.name = 'production-web-01'
+FACET status SINCE 1 hour ago
+```
+
+## Troubleshoot data visibility
+
+If you don't see data:
+
+1. Allow some time - Initial data ingestion can take a few minutes
+2. Check the time range - Ensure you're looking at recent data
+3. Verify deployment name - Use the exact name from your Collector config
+4. Check for data with NRQL:
+   ```sql
+   FROM Metric SELECT * WHERE nginx.deployment.name LIKE '%production%' LIMIT 1
+   ```
+
+If data appears intermittent:
+
+1. Check Collector logs for errors:
+   ```bash
+   sudo journalctl -u otelcol-contrib -n 50
+   ```
+2. Verify NGINX is generating traffic - Test with `curl http://localhost`
+3. Check authentication - Ensure license key and endpoint are correct
