Feature request: support metrics with unit "None"

[leandrodamascena]

Use case

Original issue: aws-powertools/powertools-lambda-python#4834

Consider changes to the TypeScript naming pattern in the text below.

docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_MetricDatum.html reports that "None" is a valid unit for CloudWatch metrics, but the MetricUnit enum does not have a member for this unit.

The lack of such a member means that there is no way to create metrics with unit "None" via Powertools. One cannot pass the string "None" as the unit parameter of Metric.add_metric, due to this code.

Solution/User Experience

Original issue: aws-powertools/powertools-lambda-python#4834

Of course, I realize that a MetricUnit member for "None" cannot be named None, but can a member with a different name (perhaps named None_ or NoUnit) please be added to the enum?

Alternative solutions

No response

Acknowledgment

• This feature request meets Powertools for AWS Lambda (TypeScript) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Python, Java, and .NET
