It's Black Friday morning. Your traffic is up 500% from normal levels. Everything looks green on your monitoring dashboards. Then you notice something troubling in your revenue reports - despite the massive traffic spike, sales are actually down compared to last year. Your site is technically "up," but something is broken in ways your monitoring isn't catching.
You dig deeper and discover the problem: your payment processor is timing out during checkout, but only under high load. Customers are filling their carts, going through checkout, entering their payment information, and then getting mysterious errors at the final step. They're abandoning their purchases and shopping elsewhere.
This scenario illustrates the fundamental challenge of e-commerce monitoring. Traditional uptime monitoring tells you if your servers are running, but it can't tell you if customers can actually complete purchases. E-commerce success depends on complex workflows that span multiple systems, third-party services, and user interactions that can fail in subtle ways.
Critical E-commerce Monitoring Points: Cart, Checkout, and Payment
E-commerce monitoring must focus on the business-critical workflows that directly generate revenue rather than just technical infrastructure health.
