Actual exam question from Google's Professional Cloud DevOps Engineer
Question #: 5
Topic #: 1
[All Professional Cloud DevOps Engineer Questions]

You are running an application in a virtual machine (VM) using a custom Debian image. The image has the Stackdriver Logging agent installed. The VM has the cloud-platform scope. The application is logging information via syslog. You want to use Stackdriver Logging in the Google Cloud Platform Console to visualize the logs. You notice that syslog is not showing up in the "All logs" dropdown list of the Logs Viewer. What is the first thing you should do?

  • A. Look for the agent's test log entry in the Logs Viewer.
  • B. Install the most recent version of the Stackdriver agent.
  • C. Verify the VM service account access scope includes the monitoring.write scope.
  • D. SSH to the VM and execute the following commands on your VM: ps ax | grep fluentd.

Between C and D, I think D Reason : When an instance is created, we can specify which service account the instance uses when calling Google Cloud APIs. The instance is automatically configured with access scope and one such access scope is monitoring.write (Link : https://cloud.google.com/compute/docs/access/service- read is to publish metric data and logging.write is to write compute engine logs. Considering above, I believe D as the answer (check whether the agent is running)

Agree. If you check here: https://cloud.google.com/logging/docs/agent/logging/troubleshooting#checklist You will see that first recommended troubleshooting step is to check if the agent is running or not... So it should be D. Also if you refer to Google Groups link provided as the answer, you will see that they first checked if the agent is running/installed.

D. Check if fluentd is running is the right answer. C is incorrect as monitoring.write scope is for monitoring agent and not logging agent.

The VM has cloud-platform scope on the VM means Full access if you using the default compute account. I would say answer D is right check is the fluentd daemon running.

i don't think so , reason is option-D is looking for fluent d which is specifically for customized logs , also by default the syslog will be captured with default monitoring agent and no need for fluent-d

https://cloud.google.com/logging/docs/agent/logging/installation Logging agent is fluentd based (now fluentbit). The Logging agent streams logs from your VM instances and from selected third-party software packages to Cloud Logging. It is a best practice to run the Logging agent on all your VM instances. The VM images for Compute Engine and Amazon Elastic Compute Cloud (EC2) don't include the Logging agent, so you must complete these steps to install it on those instances. The agent runs under both Linux and Windows. If your VMs are running in Google Kubernetes Engine or App Engine, the agent is already included in the VM image, so you can skip this page.

C, first thing to check should be the access scope. There are 3 types of scopes, default, full access and access for each API. Even thought the default scope have the Stackdriver write access, it doesn't mean the instance has the default scope. It could be access for each API. Hence, first thing to check is the scope. After that, you can check the fluentd service in the system. C over D.

Monitoring.write is for metric, so C is not correct. In that case logging.write was the right command. So D is the correct ANS ;)
