Problem
Modern web applications often suffer from bugs, performance bottlenecks, and usability issues that are difficult to diagnose without comprehensive monitoring tools. Identifying the root cause of errors and understanding user behavior requires developers to correlate data from multiple sources, leading to increased debugging time and delayed releases.
