# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'yearnv2'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
