# /usr/local/etc/prometheus.yml

global:
  scrape_interval: 5s

scrape_configs:
  - job_name:      my-server
    metrics_path:  /metrics   # (default) route to query metrics from
    scheme:        http       # (default) scheme to use for query
    static_configs:
      - targets:
        - localhost:9115      # query this ip-addr/port
