Actual exam question from Google's Professional Cloud DevOps Engineer
Question #: 31
Topic #: 1
[All Professional Cloud DevOps Engineer Questions]

Your team is designing a new application for deployment into Google Kubernetes Engine (GKE). You need to set up monitoring to collect and aggregate various application-level metrics in a centralized location. You want to use Google Cloud Platform services while minimizing the amount of work required to set up monitoring. What should you do?

  • A. Publish various metrics from the application directly to the Stackdriver Monitoring API, and then observe these custom metrics in Stackdriver.
  • B. Install the Cloud Pub/Sub client libraries, push various metrics from the application to various topics, and then observe the aggregated metrics in Stackdriver.
  • C. Install the OpenTelemetry client libraries in the application, configure Stackdriver as the export destination for the metrics, and then observe the application's metrics in Stackdriver.
  • D. Emit all metrics in the form of application-specific log messages, pass these messages from the containers to the Stackdriver logging collector, and then observe metrics in Stackdriver.

C. OpenTelemetry with Stackdriver: OpenTelemetry is a vendor-neutral instrumentation framework. By configuring Stackdriver as the export destination, you leverage a standardized approach with minimal coding effort. OpenTelemetry offers an easy way to collect and export metrics from your application to Stackdriver, minimizing setup work. Answer : C

Selected Answer: C
OpenTelemetry provides standardized metrics collection, with it's SDK and various client libraries. So using OpenTelemetry is much faster and easier than using Cloud Monitoring API directly. So it's C.

You can create user-defined metrics by using the Cloud Monitoring API directly. However, we recommend that you use OpenTelemetry. https://cloud.google.com/monitoring/custom-metrics

I think coding raw API calls is more effort than configure Open Telemetry. But maybe I am wrong.

You should use a library/SDK instead of coding raw API requests all over the place. Hence I go with C - OpenTelemetry.

The ans should be A. 3 main points here: application-level metrics use Google Cloud Platform services minimizing the amount of work required B: b is not correct as google suggest only external metrics are pushed using pub/sub. For custom metrics use stackdriver api. C: OpenTelemetry is not a gcp service D: too much work
