Telemetry handler for Finch HTTP client instrumentation.

Attaches to Finch telemetry events to track external HTTP requests:

• HTTP requests appear as "HTTP" type layers (External Services)
• Tracks URL, HTTP method, and response status code

Usage

In your application's start/2 function:

def start(_type, _args) do
  ScoutApm.Instruments.FinchTelemetry.attach()
  # ... rest of supervision tree
end

This will automatically instrument all Finch HTTP requests in your application, including those made through libraries built on Finch (like Req).

What's Tracked

• Operation: HTTP/{method} (e.g., "HTTP/GET", "HTTP/POST")
• URL: The full URL of the request (sanitized)
• Status Code: The HTTP response status code

Configuration

Requests to Scout APM's own endpoints are automatically excluded from tracking.
