如何通过CloudFormation使用CloudWatch查看EC2实例的详细监控？

If you want to set up detailed CloudWatch monitoring for EC2 instances during creation (instead of relying on the post-launch aws ec2 monitor-instances command), you can directly configure this in your CloudFormation template using the EC2 Instance resource's Monitoring property.

Key Configuration Step #

In your CloudFormation template, add the Monitoring attribute to your AWS::EC2::Instance resource and set its value to true. This switches the instance from default basic monitoring (5-minute metric intervals) to detailed monitoring (1-minute intervals).

Example CloudFormation Snippet #

Resources:
  MyMonitoredEC2Instance:
    Type: AWS::EC2::Instance
    Properties:
      ImageId: ami-1234567890abcdef0 # Replace with your target AMI ID
      InstanceType: t2.micro
      Monitoring: true # Enables detailed CloudWatch monitoring
      # Include other required properties like SubnetId, SecurityGroupIds, etc.

Important Notes #

• Cost Reminder: Detailed CloudWatch monitoring comes with additional charges compared to basic monitoring. Be sure to account for this if enabling it across multiple instances.
• No Post-Deployment Steps: Unlike the monitor-instances CLI/console action that targets existing instances, this setting takes effect as soon as the EC2 instance is provisioned via CloudFormation—no extra work needed after deployment.
• Enhanced Metrics Access: With detailed monitoring enabled, you’ll get access to the full suite of EC2 metrics (CPU utilization, disk I/O, network throughput, etc.) at 1-minute granularity in the CloudWatch console.
