Hi,

I wanted to know if it is possible to silence metrics based on an environment variable in the same way it is possible to silence logs.

Basically, I want to omit publishing metrics if the environment is not production. Ideally, that should be controllable with an env var.

Solution/User Experience

• by default, Metrics is enabled (current behavior)
• if the POWERTOOLS_METRICS_DISABLED env variable is present and truthy when the Metrics class is instantiated, then it becomes disabled
• if dev mode is enabled by means of POWERTOOLS_DEV which can be checked with this method, when the Metrics class is instantiated, then it also becomes disabled
• If POWERTOOLS_METRICS_DISABLED is set to false, and dev mode is enabled, then POWERTOOLS_METRICS_DISABLED takes precedence and the utility stays enabled.

Alternative solutions

N/A

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
