Help creating labels from OTLP formatted logs

Grafana Alloy
1

I am using Alloy to receive OTLP formatted log messages, works great! But I also want to be able to create labels from that data. For example the OTLP formatted logs have a property called resources.service.name (The JSON looks roughly like -

{
  "body": "whatever",
  "severity": "INFO",
  "flags": 1,
  "resources": {
    "host.arch": "x86_64",
    "service.name": "MyJavaApp",
  },
  "instrumentation_scope": {
    "name": "com.example.Main"
  }
}

I’m struggling with creating a loki.process component in my alloy config to create a label from it.
Anyone have any ideas on how one could do that?
