Setting bearer token in rewrites

[Brian Candler]

Suppose I have a bunch of hosts I want to poll, but with different bearer tokens.

Is there a rewrite variable I can use for this, similar to __scheme__, __address__ and __metrics_path__?

Hello,


There is none, since labels are not considered secrets.

Thank you.  So this requires a separate scrape job per target?  Or an external proxy to add the bearer token via a table lookup?

Yes. I do not know your requirements, but we also provide auth2 and tls
client certificates.

It's for scraping minio, which generates a JWT that you have to stick in the bearer token.  That's the only auth method it supports (other than public = no auth).
