Prometheus Configuration

The Cloudflare exporter needs the name of pools to be passed which can be configured by relabelling in a similar way to the blackbox exporter.

Example config:

scrape_configs:
  - job_name: cloudflare
    static_configs:
      - targets:
        - pool01 # Name of Cloudflare pool to check for.
    relabel_configs:
        - source_labels: [__address__]
          target_label: __param_target
        - source_labels: [__param_target]
          target_label: instance
        - target_label: __address__
          replacement: 127.0.0.1:8080 # The cloudflare exporter's real hostname:port.

Example result:

# HELP cloudflare_origin_health Result of health check
# TYPE cloudflare_origin_health gauge
cloudflare_origin_health{code="200",health_region="NEAS",origin_address="www01.example.com",pool_name="pool01"} 1
cloudflare_origin_health{code="503",health_region="NEAS",origin_address="www02.example.com",pool_name="pool01"} 0
# HELP cloudflare_origin_rtt_seconds RTT to the pool origin
# TYPE cloudflare_origin_rtt_seconds gauge
cloudflare_origin_rtt_seconds{code="200",health_region="NEAS",origin_address="www01.example.com",pool_name="pool01"} 0.0653
cloudflare_origin_rtt_seconds{code="503",health_region="NEAS",origin_address="www02.example.com",pool_name="pool01"} 0
