Server-Side Event Tracking: PHP, Node.js, and More

Server-Side Event Tracking Challenges

Server-side event tracking presents unique challenges including high volume, sensitive data, and different error types across various languages and frameworks.

PHP Event Tracking

<?php
class ErrorTracker {
    public static function trackError($error, $context = []) {
        $errorData = [
            'message' => $error->getMessage(),
            'file' => $error->getFile(),
            'line' => $error->getLine(),
            'trace' => $error->getTraceAsString(),
            'context' => $context,
            'timestamp' => time()
        ];
        
        // Send to tracking service
        self::sendToService($errorData);
    }
}

PHP applications can implement comprehensive event tracking using custom error handlers:

Node.js Event Tracking

process.on('uncaughtException', (error) => {
    console.error('Uncaught Exception:', error);
    // Send to tracking service
    trackError(error);
});

process.on('unhandledRejection', (reason, promise) => {
    console.error('Unhandled Rejection at:', promise, 'reason:', reason);
    // Send to tracking service
    trackError(reason);
});

Node.js applications should handle both synchronous and asynchronous events:

Database Error Handling

Database events require special attention as they often indicate serious application issues:

Performance Considerations

Server-side event tracking must be designed to minimize performance impact:

Performance Best Practices

• Use asynchronous event reporting
• Implement batching for high-volume applications
• Set up proper sampling rates
• Cache event tracking configuration
• Use background workers for error processing
