Google Professional Cloud Developer Exam - Topic 14 Question 91 Discussion

You are developing an online gaming platform as a microservices application on Google Kubernetes Engine (GKE). Users on social media are complaining about long loading times for certain URL requests to the application. You need to investigate performance bottlenecks in the application and identify which HTTP requests have a significantly high latency span in user requests. What should you do9
D) Configure GKE workload metrics using kubect1. Select all Pods to send their metrics to Cloud Monitoring. Create a custom dashboard of application metrics in Cloud Monitoring to determine performance bottlenecks of your GKE cluster.
A) Update your microservices lo log HTTP request methods and URL paths to STDOUT Use the logs router to send container logs to Cloud Logging. Create fillers in Cloud Logging to evaluate the latency of user requests across different methods and URL paths.
B) Install tcpdiimp on your GKE nodes. Run tcpdunm-- to capture network traffic over an extended period of time to collect data. Analyze the data files using Wireshark to determine the cause of high latency
C) Instrument your microservices by installing the Open Telemetry tracing package. Update your application code to send traces to Trace for inspection and analysis. Create an analysis report on Trace to analyze user requests

I feel like capturing network traffic with tcpdump could give us some insights, but it seems a bit complicated for just checking latency.

I think I practiced a question similar to this where we had to use OpenTelemetry for tracing. It might help us identify where the delays are happening.

I remember something about using Cloud Logging to track HTTP requests, but I'm not sure if that's the best way to pinpoint latency issues.

I'm leaning towards option D on this one. Monitoring the GKE cluster metrics in Cloud Monitoring could give me a high-level view of where the performance issues are, and then I can dig deeper from there. The tracing approach in option C also sounds promising, but I'm not sure I have time to implement that in the exam setting.

Option A looks like a good starting point to me. Logging the request details and using Cloud Logging to analyze the latency patterns seems like a simple but effective way to identify the problematic requests. I might go with that unless I see a really compelling reason to use a more complex solution.

Hmm, I'm a bit unsure about this one. The options all seem reasonable, but I'm not super familiar with some of the tools like tcpdump and Cloud Logging. I'll have to read through the details carefully to decide which one I think is the best approach.

BPaaS sounds like the most relevant option since the question is specifically about a hosted IP phone PBX, which is a business process. I'll go with that.

Option B with tcpdump? That's so old-school, I thought we were beyond that in the Kubernetes era. Might as well use a telegraph to debug your application.
