how to implement authentication in http_sd api

[木mumu]

in prometheus.yml,it should be like

  - job_name: 'test'

    metrics_path: '/test'

    authorization:

      credentials: mIrLtzDvPr1b90UG

      type: Token

    static_configs:

      - targets: ['10.236.114.9:8850']
now I want to do this with http_sd,my api result is 

[

{

"labels": {

"__authorization__": {

"credentials": "mIrLtzDvPr1b90UG",

"type": "Token"

},

"__metrics_path__": "/test"

},

"targets": [

"10.236.114.9:8850"

]

}

]

the notation for authentication is wrong,how to implement authentication correctly?

Google groups keeps deleting my responses, so I will try one more time.

The answer is, you can't do this.  Define the credentials statically in the job (as you did in your first example), replace static_configs with http_sd_configs, and set only the targets and auxiliary labels in your http endpoint.

Note that you *can* use labels __metrics_path__, __scheme__ and __param_XXX to override those parts of the scrape config per target, as described here.  But not the authentication settings.

thanks

If relabel_configs is designed to be exposed, then the prohibition of setting authentication by relabel is a reasonable limitation. But in use, it would be nice to have a private_relabel_configs mechanism in the future
