This dashboard charts the NGINX metrics that the OpenTelemetry Collector's nginx receiver scrapes from the stub_status page: request volume, accepted and handled connections, and current connections by state.

What This Dashboard Monitors
- Request volume: How many requests NGINX serves over the selected time range.
- Connection handling: Whether NGINX handles every connection it accepts. A gap between accepted and handled connections points to a resource limit such as
worker_connections. - Connection states: How many connections are active, reading, writing, or waiting (idle keep-alive).
Use the host.name and service.name variables at the top of the dashboard to filter by NGINX host or service.
