 Metrics can be useful to identify performance bottlenecks and pinpoint areas of high resource consumption within NGINX Gateway Fabric. To set up metrics collection, refer to the [Prometheus Metrics guide]({{< ref "prometheus.md" >}}). The metrics dashboard will help you understand problems with the way NGINX Gateway Fabric is set up or potential issues that could show up with time.
 
-For example, metrics `nginx_reloads_total` and `nginx_reload_errors_total` offer valuable insights into the system's stability and reliability. A high `nginx_reloads_total` value indicates frequent updates or configuration changes, while a high `nginx_reload_errors_total` value suggests issues with the configuration or other problems preventing successful reloads. Monitoring these metrics helps identify and resolve configuration errors, ensuring consistent service reliability.
-
-In such situations, it's advisable to review the logs of both NGINX and NGINX Gateway containers for any potential error messages. Additionally, verify the configured resources to ensure they are in a valid state.
