How do I instrument BGP basics with OpenTelemetry?

<?php
// Initialize OpenTelemetry
use OpenTelemetry\Sdk\Trace\TracerProvider;
use OpenTelemetry\SemanticAttributes;

// Create a Tracer
$tracerProvider = TracerProvider::builder()->build();
$tracer = $tracerProvider->getTracer("bgp-instrumentation");

// Define a BGP session operation
$bgpSession = $tracer->startSpan("bgpSession");

// Add attributes related to BGP connection
$bgpSession->setAttribute(SemanticAttributes::NET_PEER_IP, '192.0.2.1');
$bgpSession->setAttribute(SemanticAttributes::NET_PEER_PORT, '179');
$bgpSession->setAttribute("bgp.neighbor.as", '65001');

// Assume some BGP operations happen here...
// For example, processing and monitoring BGP updates

// End the BGP session operation
$bgpSession->end();
?>
