This is a Bug Report

Description

For bug reports:

• What went wrong?

  • Cannot use Lambdas Insight Metrics

• What did you expect should have happened?

  • Use Lambda Insight memory_utilization metric

• What was the config you used?

custom:
  lambdaInsights:
    defaultLambdaInsights: true #enables Lambda Insights for all functions
  alerts:
    stages:
      - prod
    topics:
      alarm: ${self:service}-${self:provider.stage}-alerts-alarm
      notifications:
        - protocol: email
          endpoint: ${file(./config.${self:provider.stage}.yml):EMAIL_ENDPOINT}
    definitions:
      memoryUsage:
        actionsEnabled: false
        description: 'Memory usage is too high'
        namespace: 'LambdaInsights'
        metric: memory_utilization # also try memoryUtilization
        threshold: 90
        statistic: Maximum
        period: 300

    alarms:
      - functionErrors
      - memoryUsage

• What stacktrace or error message from your provider did you see?
  • I can't see any error but the alarm is not connected to cloudwatch metric

For feature proposals:

• What is the use case that should be solved. The more detail you describe this in the easier it is to understand for us.

It appears that for the LambdaInsights namespace, the dimension name for the function should be function_name and not FunctionName in the generated CloudFormation template:

"Dimensions": [
  {
    "Name": "FunctionName",
    "Value": {
      "Ref": "NameOfLambdaLambdaFunction"
    }
  }
],

should be:

"Dimensions": [
  {
    "Name": "function_name",
    "Value": {
      "Ref": "NameOfLambdaLambdaFunction"
    }
  }
],
