Setting up a fallback module in Blackbox.

[yagyans...@gmail.com]

Hi. I want to use a single job and a file for probing targets with different modules. My job currently looks like this.

  - job_name: 'blackbox_TestingAllInSameFile'

    metrics_path: /probe

    file_sd_configs:

      - files:

        - /root/test.yml

    relabel_configs:

      - source_labels: [__address__]

        target_label: __param_target

      - source_labels: [__param_target]

        target_label: instance

      - source_labels: [module]

        target_label: __param_module

      - target_label: __address__

        replacement: 172.20.10.99:9115

    scrape_interval: 10s

My target file looks like this:

- targets:

     - t1

     - t2

  labels:

     module: 'http_healthcheck'

     checkname: 'a'

     cluster: 'b'

     node: 'c'

     env: 'PROD'

My http_healthcheck module will be used for most of the targets. So, is there any way to make it as a fallback module and not define module label everytime for this particular module? I mean I want to define the module label only when it is anything other than http_healthcheck.

Is there any way we could achieve this using relabel_configs?

Thanks in advance!

Yes, you could do:

- source_labels: [__param_module]
regex: '()'
replacement: 'http_healthcheck'
target_label: __param_module

Thanks, Julien.

Hi Julien,

One query.

Using this regex combination that you mentioned, the module is getting set to http_healthcheck itself for all the targets even if I specify a different module for some of the targets.
