How can I set up logging in AWS SAM templates?

You can set up logging in AWS SAM templates by defining a LogGroup resource and associating it with your Lambda function.

Can you show me an example of a SAM template with logging?

Sure! Here's a simple example:

Resources:
  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: index.handler
      Runtime: nodejs14.x
      Policies:
        - AWSLambdaBasicExecutionRole
      Environment:
        LOG_GROUP_NAME: !Ref MyLogGroup

  MyLogGroup:
    Type: AWS::Logs::LogGroup
    Properties:
      LogGroupName: /aws/lambda/MyFunction
      RetentionInDays: 14

What permissions do I need for logging?

You need to attach the AWSLambdaBasicExecutionRole policy to your Lambda function, which includes permissions for logging.

Can I customize the log retention period?

Yes, you can customize the log retention period by setting the RetentionInDays property in the LogGroup resource.
