It captures:

• HTTP version (http.flavor);
• HTTP host (http.host);
• Client IP (http.client_ip);
• User agent (http.user_agent);
• Request path (http.target);
• Status code (http.status_code);
• Request id (request_id);
• Display (exception.message) and Debug (exception.details) representations of the error, if there was an error;
• Request id (request_id);
• OpenTelemetry trace identifier (trace_id). Empty if the feature is not enabled;
• OpenTelemetry span kind, set to server (otel.kind).

All field names follow OpenTelemetry’s semantic convention.
