Exam Professional Cloud Developer topic 1 question 7 discussion

B Process-health policy A process-health policy can notify you if the number of processes that match a pattern crosses a threshold. This can be used to tell you, for example, that a process has stopped running.

C Metric absence You want to be alerted if the UNIX process has not run for at least 5 minutes. Since you cannot modify the application to generate metrics or logs, you need to rely on detecting the absence of metrics collected by the Stackdriver Monitoring Agent.

If the requirement is to simply determine whether a process has stopped reporting metrics, Metric Absence is the preferred choice.

Metric absence allows you to trigger an alert if no metrics (e.g., CPU usage, memory usage, etc.) related to the process are received for a specific period, such as 5 minutes

To be alerted if your Unix process has not run for at least 5 minutes, you should configure a **metric absence** alert condition. Since you cannot modify the application to generate metrics or logs, this approach allows you to monitor the absence of data for a specific duration. When the Unix process stops running, the metric data will be absent, triggering the alert. Therefore, the correct answer is **C. Metric absence**. This type of alerting policy will help you stay informed about any unexpected interruptions in your process execution.

B is correct.
