2. Click on "Create Policy".
3. Select the condition type, such as an uptime check or metric threshold.
4. Configure the condition details, such as the metric to monitor and the threshold value.
5. Set up notification channels, such as email or SMS, to receive alerts.
6. Click "Save" to create the alerting policy.

Condition: Uptime check failed
Threshold: Greater than 0
Notification Channel: Email (admin@example.com)

Monitoring Metrics

Cloud Monitoring allows you to monitor various metrics related to your resources, such as CPU usage, memory usage, and network traffic. Here's how to view and analyze metrics:
