# Metrics and Metadata Overview Product: AMPLIF > Learn about the metrics and metadata F5 NGINX Amplify collects. --- Most metrics are collected by F5 NGINX Amplify Agent without requiring the user to perform any additional setup. For troubleshooting, see [Troubleshooting Metrics Collection](/amplify/nginx-amplify-agent/troubleshooting-metrics-collection.md). Some additional metrics for NGINX monitoring will only be reported if the NGINX configuration file is modified accordingly. See [Additional NGINX Metrics](/amplify/metrics-metadata/nginx-metrics#additional-nginx-metrics), and review the *Source* and *Variable* fields in the metric descriptions that follow.
