Metrics

The Shark.Fido2.Sample application exposes metrics at the /metrics endpoint.

Running the Prometheus Server

1. Create a prometheus.yml file with the following content:

   global:
     scrape_interval: 5s
   
   scrape_configs:
     - job_name: "shark_fido2_sample"
       scheme: https
       tls_config:
         insecure_skip_verify: true
       static_configs:
         - targets: ["host.docker.internal:8082"]
   

2. Start the Prometheus server in Docker

   docker run -p 9090:9090 -v ./prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus.

3. Start the sample application.

4. Open the application at https://localhost:8082/.

5. Interact with the application (e.g., create public key credentials).

6. Open the Prometheus server UI at http://localhost:9090/

7. Run the following sample query and switch to the Graph tab to view requests per second (RPS) across all endpoints:

   sum(rate(http_requests_received_total[1m]))
