Front-End applications are judged by how the UI feels to users—the perceived performance and the experience during interaction. That means not just how fast code runs, but how quickly content renders, how responsive actions are, and how performance tracks as demand changes. ITSI supports this by bringing together telemetry from the client side and the rest of the stack to provide data-driven service intelligence. With this, you can define metrics around user experience—like load times, time to interactive, and error rates—and see how frontend performance correlates with backend and infrastructure health. This holistic view helps teams diagnose issues that directly affect users and drive improvements.

The other options are too narrow: focusing only on server-side logs, or only on database query performance, misses the user-facing aspect of Front-End apps. Hardware procurement is unrelated to the real-time experience users have with the UI.
