More labels

[bahamat]

As an operator, some other labels I always want are account and datacenter_name. I have these additional relabel_configs

    - source_labels: [__param_datacenter_name]                                  
      target_label: datacenter_name                                             
      replacement: ${dc}                                                        
    - source_labels: [__param_account]                                          
      target_label: account_name                                                
      replacement: ${user}

I'm not sure I'm following how the __param_* relabels are used. Are you adding datacenter_name=foo to the url when you query Prometheus (which otherwise has no notion of DCs), to inject it into the results?

No, I'm using this as a way to arbitrarily add labels. The __param_* labels don't need to exist and in this context have no meaning. They may as well be random strings, if you wanted to ensure that there was no collision.
