End-User Monitoring in Production

In this episode of Test in Production, we discuss Real User Monitoring (RUM) and Synthetic Monitoring with Zach Henderson from Catchpoint. We explore how to use these monitoring techniques to improve the performance and reliability of your applications. We also delve into some interesting bugs that can arise when using these tools. Some key takeaways include: - Real User Monitoring (RUM) involves collecting data about how real users are interacting with your application, including metrics such as page load times, error rates, and user engagement. - Synthetic Monitoring involves simulating user interactions with your application to proactively identify performance issues before they impact real users. - To effectively use RUM and Synthetic Monitoring, it's important to establish clear goals and metrics for success, as well as a plan for how you will respond to any issues that are identified. - One interesting bug that can arise when using these tools is the issue of network time synchronization (NTP). This can cause delays in user interactions with your application if not properly addressed.
