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?

APublish various metrics from the application directly to the Slackdriver Monitoring API, and then observe these custom metrics in Stackdriver.

BInstall the Cloud Pub/Sub client libraries, push various metrics from the application to various topics, and then observe the aggregated metrics in Stackdriver.

CInstall 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.

DEmit 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.

Your application can report a custom metric to Cloud Monitoring. You can configure Kubernetes to respond to these metrics and scale your workload automatically. For example, you can scale your application based on metrics such as queries per second, writes per second, network performance, latency when communicating with a different application, or other metrics that make sense for your workload. https://cloud.google.com/kubernetes-engine/docs/concepts/custom-and-external-metrics

C is definitely the way to go, OpenTelemetry is super reliable!

B sounds like overkill for just monitoring metrics.

I’m surprised that using logs for metrics (D) is even an option.

I disagree, I think A could work too, but it might be more complex.

Option C seems like the best choice for easy integration with Stackdriver.

I’m a bit confused about whether we should use Cloud Pub/Sub for metrics; it seems like overkill for what we need, right?

I feel like option C is the most straightforward since it mentions using OpenTelemetry, which we practiced a lot.

I think we discussed using OpenTelemetry in one of our practice sessions, but I'm not entirely sure how it integrates with Stackdriver.

I remember something about publishing metrics directly to Stackdriver, but I can't recall if that's the best approach for GKE.

Hmm, this is a tricky one. I know the Advanced report has a lot of detailed options, so that's my best guess. But I'm not 100% sure about the exclusionary operators part.

I'm leaning towards option B. Deleting the old entitlement and creating a new one from scratch might be the most straightforward approach, especially if there are any complications with the existing one. As long as I get the new parameters right, that should work.

I'm a bit unsure about this one. I know colchicine can affect various lab tests, but I'm not sure which specific ones. I'll have to make an educated guess.
