Example Prometheus Configuration

scrape_configs:
  - job_name: 'dns_exporter'
    dns_sd_configs:
      - names: ['_ldap._tcp.dc._msdcs.example.com']
    metrics_path: /dns
    relabel_configs:
      - source_labels: [__address__]
        regex: (.*):[0-9]+
        target_label: __param_nameserver
      - source_labels: [__param_nameserver]
        target_label: instance
      - target_label: __address__
        replacement: 'localhost:9998'
      - source_labels: [__address__]
        target_label: probe
  - job_name: 'dns_normalized_exporter'
    dns_sd_configs:
      - names: ['_ldap._tcp.dc._msdcs.example.com']
    metrics_path: /dns_normalized
    relabel_configs:
      - source_labels: [__address__]
        regex: (.*):[0-9]+
        target_label: __param_nameserver
      - source_labels: [__param_nameserver]
        target_label: instance
      - target_label: __address__
        replacement: 'localhost:9998'
      - source_labels: [__address__]
        target_label: probe
  - job_name: 'icmp_exporter'
    dns_sd_configs:
      - names: ['_ldap._tcp.dc._msdcs.example.com']
    metrics_path: /icmp
    relabel_configs:
      - source_labels: [__address__]
        regex: (.*):[0-9]+
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 'localhost:9998'
      - source_labels: [__address__]
        target_label: probe

Notes

• The replacement: 'localhost:9998' under relabel_configs is the addresses of the exporter you want to scrape data from. So, if you want to be able to log ICMP RTTs to some server from another endpoint, you would add another job with a relabel config that sets the target address to a different exporter.
