Comprehensive and Detailed Explanation:
Google Cloud Trace is specifically designed to analyze request latency and identify performance bottlenecks across services. Since the issue is related to slow performance after a new release, the best approach is to use Cloud Trace to:
Visualize request latency across services
Pinpoint slow dependencies affecting response time
Analyze performance trends over time
????Why not other options?
B (Error Reporting)❌→ Focuses on uncaught exceptions and crashes, not latency issues.
C (Cloud Profiler)❌→ Helps with CPU and memory analysis, not request tracing.
D (Prometheus for Cloud Monitoring)❌→ Useful for metrics collection, but not ideal for debugging specific request latency issues.
