Hi @ffje , thanks for the contribution! From looking at the docs, it seems like there should be more dimensions listed?

[ffje]

that's right @iwysiu, thanks for noticing! Will add it soon.

hey @iwysiu I've updated the PR. However, I'm not sure it worth to keep something besides my initial proposed metrics: GetEventPrediction, GetEventPredictionLatency, GetEventPrediction4XXError, GetEventPrediction5XXError. And the only dimension - DetectorID.

AWS Cloudwatch console does not show any metrics except those. Could you please advice, should I keep as is or revert it back?

[iwysiu]

Thanks @ffje ! (I don't have fraud detector set to test this myself) Does using the other dimensions do anything/successfully query? If so, I'd keep them, otherwise feel free to revert it.

[ffje]

@iwysiu Thanks for suggestion. For my own FraudDetector setup it does nothing, however there are multiple FraudDetector types, so it might be useful for other ones. I'd keep it as is for now.

Any further steps should I do to proceed with PR? Thanks in advance. (seems I don't have permissions to put appropriate labels to make CI checks fully green)

[iwysiu]

LGTM! Nope, there's nothing else you have to do, I'll handle the CI checks. Thanks again for contributing!
