You have a Compute Engine instance hosting a production application. You want to receive an email if the instance consumes more than 90% of its CPU resources for more than 15 minutes. You want to use Google services. What should you do?
A.
1. Create a consumer Gmail account. 2. Write a script that monitors the CPU usage. 3. When the CPU usage exceeds the threshold, have that script send an email using the Gmail account and smtp.gmail.com on port 25 as SMTP server.
B.
1. Create a Cloud Monitoring Workspace and associate your Google Cloud Platform (GCP) project with it. 2. Create a Cloud Monitoring Alerting Policy that uses the threshold as a trigger condition. 3. Configure your email address in the notification channel.
C.
1. Create a Cloud Monitoring Workspace and associate your GCP project with it. 2. Write a script that monitors the CPU usage and sends it as a custom metric to Cloud Monitoring. 3. Create an uptime check for the instance in Cloud Monitoring.
D.
1. In Cloud Logging, create a logs-based metric to extract the CPU usage by using this regular expression: CPU Usage: ([0-9] {1,3})% 2. In Cloud Monitoring, create an Alerting Policy based on this metric. 3. Configure your email address in the notification channel.
B
By setting up a Cloud Monitoring Alerting Policy and configuring the notification channel to an email address, you can receive email alerts when the CPU usage exceeds the threshold that you set. This can be done by using Google Cloud's built-in monitoring and alerting features, which can be more reliable and easier to manage than setting up a custom script or using external email services.
The most appropriate and efficient method to set up an alert for high CPU usage on a Google Compute Engine instance using Google's services would be:
B.
1. Create a Cloud Monitoring Workspace and associate your Google Cloud Platform (GCP) project with it.
2. Create a Cloud Monitoring Alerting Policy that uses the threshold as a trigger condition. 3. Configure your email address in the notification channel.
This option utilizes Google Cloud's built-in Cloud Monitoring service to track the CPU usage and send alerts based on predefined conditions without the need for scripting or managing an email server.
D. 1. In Cloud Logging, create a logs-based metric to extract the CPU usage by using this regular expression: CPU Usage: ([0-9] {1,3})% 2. In Cloud Monitoring, create an Alerting Policy based on this metric. 3. Configure your email address in the notification channel.
answer is B, but I would write it this way as stackdriver is deprecated and Operation Suite uses scopes now.
1. Create a Cloud Monitoring metric scope and associate your Google Cloud Platform (GCP) project with it.
2. Create a Cloud Monitoring Alerting Policy that uses the threshold as a trigger condition.
3. Configure your email address in the notification channel.
The dump has been changed some days ago. This answer was the old and best version:
1. Create a Stackdriver Workspace, and associate your Google Cloud Platform (GCP) project with it.
2. Create an Alerting Policy in Stackdriver that uses the threshold as a trigger condition.
3. Configure your email address in the notification channel.
