How do you troubleshoot OpenTelemetry when it fails?

// Example: Basic troubleshooting steps for OpenTelemetry
try {
    // Initialize OpenTelemetry
    $tracer = OpenTelemetry\Sdk\TracerProvider::getTracer('my-instrumentation');
    
    // Start a new span
    $span = $tracer->startSpan('my-operation');
    // Your application logic here...
    
    // End the span
    $span->end();
} catch (Exception $e) {
    // Log error for debugging
    error_log('OpenTelemetry Error: ' . $e->getMessage());
}
