The holiday shopping season can be stressful for ecommerce businesses due to the surge of traffic, which can put a strain on their websites. To mitigate this stress, having an active monitoring solution is crucial to identify website issues before customers do. Synthetic monitoring simulates real user actions to mirror exact user flows, allowing for quick and reliable identification of website issues. Checkly makes it easy to create synthetic monitoring checks with key user flows, such as adding items to a shopping cart, checking out, and collecting a payment, which can be configured to alert immediately about any issues. A checklist is provided to help ecommerce sites set up a monitoring regimen, including starting with low-hanging fruit, getting solid alerting in place, leveraging site history, and monitoring API endpoints among other recommendations.
