- What Grafana version and what operating system are you using? alloy, version v1.9.2 using Rocky 9.5

- **What** are you trying to achieve? Setting up authentication ( any kind ) between Alloy agent and Alloy proxy

- **How** are you trying to achieve it? using prometheus.receive\_http

- What happened? i cant seem to setup any kind of authentication between then so only authenticated servers can send data

- What did you **expect** to happen? tried http {} block but its not working

- Can you copy/paste the configuration(s) that you are having problems with? Yes here it is: http {  
auth {  
basic {  
username = “admin”  
password = “/etc/alloy/secrets/mimir-password”  
}  
filter {  
paths = [“/metrics”, “/v1”]  
authenticate\_matching\_paths = true  
}  
}  
}

- Did you receive any errors in the Grafana UI or in related logs? If so, please tell us **exactly** what they were. When i tried auth inside receiver\_http it doesnt exist

- Did you follow any online instructions? If so, what is the URL? Did not find any accurate ones

Looking at the HTTP block I don’t see a way to configure simple auth.

Not sure how you segment your network, but I don’t think this is a common use case. If you really want authentication on an Alloy proxy, putting alloy behind nginx with simple auth might be your easiest workaround.
