Research direction

Start with the linked Azure Monitor Java standalone configuration documentation, especially the preview roleNameOverrides section, then locate the existing implementation of that feature in the repository. Determine how the request hostname is exposed to the agent and how override matching currently works. Done means hostname-based prefixes can select the configured role name, with coverage for the examples in the issue.

Description

Enhancement

I've seen the preview feature, which I think is great: https://learn.microsoft.com/en-us/azure/azure-monitor/app/java-standalone-config#cloud-role-name-overrides-preview

I think it would be a good extension if you could also use the hostname as a prefix.

e.g. you have two domains like https://app1.my-domain.com and https://app2.my-domain.com

E.g.

{
  "preview": {
    "roleNameOverrides": [
      {
        "hostPrefix": "app1",
        "roleName": "Role A"
      },
      {
        "hostPrefix": "app2",
        "roleName": "Role B"
      }
    ]
  }
}

{
  "preview": {
    "roleNameOverrides": [
      {
        "hostPrefix": "app1.my-domain.com ",
        "roleName": "Role A"
      },
      {
        "hostPrefix": "app2.my-domain.com ",
        "roleName": "Role B"
      }
    ]
  }
}
