Question regarding probing remote instances having basic auth

[svenmueller]

Hi,

Some of our instances (e.g. staging servers) are protected using BASIC AUTH. Is there a way using blackbox-exporter to probe those servers (e.g. using module http_2xx)

Thx in Advance,
Sven

You can pass in headers with the http module, which would let you do basic auth.

[svenmueller]

Ok. So we would need to have have multiple module configurations if we have targets using differrent BASCI AUTH credentials, right? Or is there a way to pass the headers for each target like done with the targets in the Prometheus configuration (via relabeling).

[brian-brazil]

Yes, you'd need a module config per different set of credentials.

I'd suggest looking into having a monitoring set of credentials that works across targets.

[svenmueller]

Yes, that would be one way of limiting the amount of required modules.

Btw, thx for your awesome work here (and all other Prometheus related project). I really appreciate it!

Cheers Sven
