Send logs to prometheus gateway

[germankuber]

I want to configure grafana alloy to send me metrics to prometheus gateway instead mimir.
My config.river is :

otelcol.receiver.otlp "default" {
  grpc {}
  http {}
  output {
    metrics = [otelcol.exporter.prometheus.default.input]
  }
}

otelcol.exporter.prometheus "default" {
  forward_to = [prometheus.remote_write.local.receiver]
}

prometheus.remote_write "local" {
  endpoint {
    url = "http://localhost:9091/metrics/job/example"
  }
      headers = {
            "Content-Encoding" = "snappy",
      }
}

I am getting this error in the agent :

ts=2024-06-05T23:08:33.162192211Z level=error msg="non-recoverable error" component_path=/ component_id=prometheus.remote_write.local subcomponent=rw remote_name=bcf55f url=http://localhost:9091/metrics/job/example count=10 exemplarCount=0 err="server returned HTTP status 400 Bad Request: snappy: corrupt input"

I see that I cant disable the compression from config.river, do you have another approach ?

Thank you.

Hello. Is this question for grafana/alloy?

Seems like a grafana/alloy question so I'm going to close this.
