Description

This is a Question / Feature Proposal

Description

For bug reports:

  • What went wrong?
  • What did you expect should have happened?
  • What was the config you used?
  • What stacktrace or error message from your provider did you see?

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. Is it possible to create an alarm with math expressions? For example I would like to have a health percentage (100 - 100 * errors / invocations). Is this possible already to define somehow?

Contributor guide

Research direction
Research whether AWS CloudWatch supports math expressions in alarms and how to integrate them into the serverless plugin aws alerts. Look at CloudWatch Metrics Math documentation and the plugin's current alarm definition structure.
