Exam Professional Cloud DevOps Engineer topic 1 question 17 discussion

* https://cloud.google.com/anthos/clusters/docs/on-prem GKE on-prem is also called Anthos clusters on VMware * https://cloud.google.com/anthos/clusters/docs/on-prem/concepts/logging-and-monitoring You have several logging and monitoring options for your Anthos clusters on VMware: + Cloud Logging and Cloud Monitoring, enabled by in-cluster agents deployed with Anthos clusters on VMware. + Prometheus and Grafana, disabled by default. + Validated configurations with third-party solutions. => it means, if not a special situation, the correct should be using the first option: Logging and Monitoring. In this case, we want metrics, so Monitoring (aka. Cloud Monitoring, Stackdriver Monitoring) should be used. We are talking about GKE, so we will use Kubernetest Engine Monitoring (https://cloud.google.com/kubernetes-engine-monitoring). Obviously, A is correct.

B correct

GKE on prem also has all the agents required to send metrics/logs to Cloud Monitoring (previously Stackdriver). So as of now, A is the right answer.

The answer will change pre and post GKE 1.24 release. If the question is asked before the release of GKE 1.24 the answer should be A. Post GKE 1.24 release metrics deprecated, B is the answer.

If the on-prem was a non-GKE kubernetes solution, the the answer would be B. But it's GKE on-prem, A is the best option here

option A

GKE workload monitoring has been deprecated, so should be Prometheus https://cloud.google.com/stackdriver/docs/solutions/gke/managing-metrics

It should be B check this link It is clearly mentioned if you are application running on GKE or anthos cluster on Vmware you use stack driver counter part but if it is on On-prem then better find other solution With respect to options we have here it is prometheus https://cloud.google.com/anthos/clusters/docs/on-prem/latest/concepts/logging-and-monitoring#:~:text=For%20applications%20with%20components%20running%20on%20Anthos%20clusters%20on%20VMware%20and%20traditional%20on%2Dpremises%20infrastructure%2C%20you%20might%20consider%20other%20solutions%20for%20an%20end%2Dto%2Dend%20view%20of%20those%20applications

Prometheus is made for metrics not logs, in this way the correct answer is A, not be.

B. Use Prometheus to collect and aggregate logs per container, and then analyze the results in Grafana. Prometheus is a popular open-source monitoring and alerting system that is well-suited for monitoring containers running in a Kubernetes cluster. It can scrape metrics from the Kubernetes API server and export them to a time series database, where they can be queried and visualized in Grafana. This approach allows you to monitor CPU and memory usage of individual containers, and set up alerts if usage exceeds certain thresholds.

You support an e-commerce application that runs on a large Google Kubernetes Engine (GKE) cluster deployed on-premises and on Google Cloud Platform. The application consists of microservices that run in containers. You want to identify containers that are using the most CPU and memory. What should you do? A. Use Stackdriver Kubernetes Engine Monitoring. B. Use Prometheus to collect and aggregate logs per container, and then analyze the results in Grafana. C. Use the Stackdriver Monitoring API to create custom metrics, and then organize your containers using groups. D. Use Stackdriver Logging to export application logs to BigQuery, aggregate logs per container, and then analyze CPU and memory consumption.

I think the answer is B. A cant be because is not for on premises.

Ans: A Exam passed and taken on 19/12/2022, 50/50 from this dump without buying the full access and looking for 'devops' word here: https://www.examtopics.com/discussions/google/1/

Ans A - Anthos GKE On-Prem agent collects systems metric however it doesn't collect applications metric. Given that question asks for CPU and Memory GKE On-Prem agent should suffice of containers in on-prem.

for anthos clusters, need cloud monitoring & cloud logging agent, not GKE monitoring.

The Cloud Operations Suite for GKE only displays information for GKE clusters running on Google Cloud. It does not display information for GKE clusters running elsewhere, such as using on-premises or bare metal servers https://cloud-google-com.translate.goog/stackdriver/docs/solutions/gke?hl=fr&_x_tr_sl=fr&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=sc

The eCommerce app is a workload. Since v. 1.24 GKE workload metrics were deprecated and replaced with Prometheus https://cloud.google.com/stackdriver/docs/solutions/gke/workload-metrics#gcloud https://cloud.google.com/stackdriver/docs/solutions/gke/gmp-migration
