# Metrics and Metadata Overview


> 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.
