could any one please help me the lambda code , whenever AWS Ec2 instances get stopped, we need to get the email notifications with sns. In the email we need instance name. I could able to get instance id but not the instance name.

AWS CloudTrail allows you to identify and track EC2 instance lifecycle API calls (launch, start, stop, terminate). See How do I use AWS CloudTrail to track API calls to my Amazon EC2 instances?

And you can trigger a Lambda function to run arbitrary code when CloudTrail logs certain events. See Triggering a Lambda function with AWS CloudTrail events.

You can also create an Amazon CloudWatch alarm that monitors an Amazon EC2 instance and triggers a Lambda via CloudWatch Events.

CodePudding user response：

You can create a rule in Amazon CloudWatch Events that:

• Triggers when an instance enters the Stopped state
• Sends a message to an Amazon SNS Topic

Like this:

If you want to modify the message that is being sent, then configure the Rule to trigger an AWS Lambda function instead. Your function should:

• Extract the instance information (eg InstanceId) from the event parameter
• Call describe-instances to obtain the Name of the instance (presumably the Tag with a Key of Name)
• Publish a message to the Amazon SNS Topic
