add ignoreNullValues for AWS CloudWatch Scaler #5635

robpickerill · 2024-03-28T15:03:29Z

This PR adds support for erroring the AWS Cloudwatch Scaler when the GetMetricData call returns an empty set of metrics, resulting in no scale-changing behaviour when no custom metrics are available during the Cloudwatch query window.

I added end to end tests here for both minMetricValue and errorWhenNullValues to cover off both scenarios. I need to tidy them up a little, which ill do over the next few days.

Fixed conflicts, this needs another e2e test run

@robpickerill there is also a problem in static checks

@robpickerill there is also a problem in static checks

Fixed, all tests should pass now.

I see e2e didn't run due to Azure cluster scaling actions failing, would it be easier for me to put the e2e tests in a different PR and unblock this PR? The unit tests here cover the error case for the scaler, but I wanted to add e2e to prove the backward compatibility for the change.

Let me know what works best for you.
