Running an example that shows metrics data?

1. Launch a local metrics server, which exposes the metrics data via the /metrics endpoint.

You can choose one of the following:

• Collection Node:

  go run module/metrics/example/collection/main.go
  

• Execution Node:

  go run module/metrics/example/execution/main.go
  

• Verification Node:

  Note: Running example with -happypath flag examines the metrics collection on a real happy path of verification node.

  go run module/metrics/example/verification/main.go
  

• Consensus Node:

  go run module/metrics/example/consensus/main.go
  

The above commands each launch a metrics server on localhost with port 9090

2. Install the prometheus server

brew install prometheus

3. Launch the prometheus server to scrape the metrics from our local metrics server

prometheus --config.file=module/metrics/example/prometheus.yml

4. Open the prometheus UI in your browser http://localhost:9090/graph

5. Go to the "Graph" tab to query and verify the collected metrics data type consensus_cur_view, and press "Enter" to view the metrics data over time
