Your organization runs multiple applications on Compute Engine, with instances generating logs and metrics displayed on dashboards. A new requirement has emerged to capture operating system (OS) level logs for security purposes. How can you meet this requirement?
Explanation:
The correct approach is to install the FluentD agent for capturing OS-level logs. The other options are incorrect because: CollectD is not suitable for OS-level logs, log-based metrics require logs already in Cloud Logging, and sinks can only route logs present in Cloud Logging. For more details, refer to the guide on installing the agent via the Google Cloud console.
