Blackbox are not recognizing another modules than not is http_2xx

[Ricardo Estalder]

Hello
I have the following issue with blackbox exporter module
Currently the blackbox are not recognized another module that no is http_2xx
These are my config files

prometheus.yml

  - job_name: 'blackbox'
    metrics_path: /probe
    file_sd_configs:
      - files:
          - '/etc/prometheus/blackbox/targets/*.yml'
    relabel_configs:
      - source_labels: [__address__]
        separator: ;
        regex: (.*)
        target_label: __param_target
        replacement: $1
        action: replace
      - source_labels: [__param_target]
        separator: ;
        regex: (.*)
        target_label: instance
        replacement: $1
        action: replace
      - target_label: __address__
        replacement: prometheus.edgelan:9115 # The blackbox exporter
        action: replace

Blackbox

config.yml

   modules:
      https_2xx:
        prober: http
        timeout: 5s
        http:
          method: GET
          no_follow_redirects: false
          fail_if_ssl: false
          fail_if_not_ssl: true
          preferred_ip_protocol: "ipv4"
      http_2xx:
        prober: http
        timeout: 5s
        http:
          method: GET
          no_follow_redirects: false
          fail_if_ssl: true
          fail_if_not_ssl: false
          preferred_ip_protocol: "ipv4"

#Target config files

http_2xx.yml

- labels:
    module: http_2xx
  targets:
  - http://www.stealmylogin.com/

https_2xx.yml

- labels:
    module: https_2xx
  targets:
  - https://www.sethryder.com
  - https://www.modpackindex.com

On the logs of the probe only matches with module http_2xx but no the module https_2xx or another modules present on the config file
When i delete all the modules and only set the module https_2xx the probe logs show Unknown module "http_2xx" that means what I said before, blackbox is not recognize another modules that no is http_2xx

In your relabeling, you also need to copy label "module" to "__param_module" (otherwise it won't get sent to the exporter)

Thank now it works !

    relabel_configs:
      - source_labels: [module]
        target_label: __param_module
      - source_labels: [module, __address__]

        target_label: __param_target
        replacement: $1
        action: replace
      - source_labels: [__address__]
        separator: ;
        regex: (.*)
        target_label: __param_target
        replacement: $1
        action: replace
      - source_labels: [__param_target]
        separator: ;
        regex: (.*)
        target_label: instance
        replacement: $1
        action: replace
      - target_label: __address__
        replacement: prometheus.edgelan:9115 # The blackbox exporter
        action: replace

Not sure what's going on: there's no need to join labels together, and then later on you replace __param_target anyway.

It should simplify down to:

    relabel_configs:

      - source_labels: [__address__]

        target_label: instance

      - source_labels: [__address__]

        target_label: __param_target

      - source_labels: [module]

        target_label: __param_module
