[All Professional Cloud DevOps Engineer Questions]

Your company processes IoT data at scale by using Pub/Sub, App Engine standard environment, and an application written in Go. You noticed that the performance inconsistently degrades at peak load. You could not reproduce this issue on your workstation. You need to continuously monitor the application in production to identify slow paths in the code. You want to minimize performance impact and management overhead. What should you do?

  • A. Use Cloud Monitoring to assess the App Engine CPU utilization metric.
  • B. Install a continuous profiling tool into Compute Engine. Configure the application to send profiling data to the tool.
  • C. Periodically run the go tool pprof command against the application instance. Analyze the results by using flame graphs.
  • D. Configure Cloud Profiler, and initialize the cloud.google.com/go/profiler library in the application.

Selected Answer: D
Choose option D Configure Cloud Profiler and initialize the cloud.google.com/go/profiler library in the application. Cloud Profiler is designed for low-overhead continuous profiling in production environments. By configuring Cloud Profiler and initializing the corresponding library in the Go application, you can collect detailed performance data without significantly impacting the application's performance. This approach allows you to analyze profiling information, identify slow paths in the code, and gain insights into performance bottlenecks, providing a powerful and efficient way to troubleshoot and optimize the application in a production environment.
