AppScaling DescribeScalingPolices FailedResourceAccessException due to throttling

[s-maj]

Version of AWS SDK for Go?

aws-sdk-go/1.8.34

Version of Go (go version)?

go1.8.3; darwin; amd64

What issue did you see?

On DescribeScalingPolices, due to throttling, I am getting:
FailedResourceAccessException: Unable to retrieve alarms for scaling policy $policy_arn due to reason: Rate exceeded (Service: AmazonCloudWatch; Status Code: 400; Error Code: Throttling; Request ID: ce1253eb-81e9-11e7-ba0a-dd79b677bd46)

From what I understand DescribeScalingPolices is doing DescribeAlarms on behalf and this call is being throttled. FailedResourceAccessException is a very general error and I'm not quite sure how to handle it. I can retry but what if there is a real permission problem or the alarm resource does not exist anymore?

Steps to reproduce

DescribeScalingPolices very fast using tons of resources

Looking at the

aws-sdk-go/service/applicationautoscaling/errors.go

Line 43 in feaea4b

ErrCodeLimitExceededException = "LimitExceededException"

I can see a quite suitable error for this case but it's not listed in API documentation (http://docs.aws.amazon.com/ApplicationAutoScaling/latest/APIReference/API_DescribeScalingPolicies.html).

Hello @s-maj, thank you for reaching out to us. I am going to go ahead and forward this to the service team as this isn't an issue with the SDK. The best place for these types of issues is the service team forums. Please let us know if you have any additional issues!
