Relay Server serves these metrics produced by Prometheus from a Unix socket.
To retrieve metrics from the Relay Server's Unix socket, you can use the curl command to make a request to the following endpoint: http://localhost/metrics on the Unix socket /var/run/Binalyze.AIR.Relay.sock. Here's an example command:
Executing this command will provide you with a response containing various metrics related to the Relay Server. The response will include information such as the number of active connections, request duration, request errors, reload count, and more.
Please note that you need to run this command on the same system where the Relay Server is running, as it communicates via the Unix socket.
Here's a sample response:
