Option A is not suitable as the logging agent does not gather latency data. Option B is incorrect because the Cloud Debugger is designed for real-time application state inspection, not latency analysis. Option C is also incorrect since the monitoring agent does not collect latency data. Option D is the correct choice because Cloud Trace offers distributed tracing capabilities, allowing you to inspect both individual request latencies and aggregate application latency through its console.
