Hi @jordanefillatre ! Thanks for the contribution. Would you mind signing the CLA and reordering the new metrics to be in alphabetical order with the old ones?

Adding a link to the documentation: https://docs.aws.amazon.com/AmazonS3/latest/userguide/metrics-dimensions.html
Have you tried it and confirmed that it works? I noticed that the documentation didn't explicitly list the namespace

[jordanefillatre]

Hi @iwysiu ,
You're right, the documentation isn't very clear about namespace.
I have confirm it by querying api using aws cli:

            "MetricName": "OperationsFailedReplication",
            "Dimensions": [
                {
                    "Name": "SourceBucket",
                    "Value": "xxx"
                },
                {
                    "Name": "DestinationBucket",
                    "Value": "xxx"
                },
                {
                    "Name": "RuleId",
                    "Value": "crr-full-standard"
                }
            ]
        },

It also show that I have omitted to add required dimensions.

Last I've take more time to manually check manually the fix by running a dev environment. I can confirm that it works after last commit update:

[iwysiu]

Looks good! Thanks for fixing the Dimensions and checking the namespace. Just one little alphabetization fix.

[jordanefillatre]

Oh, so sorry

[iwysiu]

No problem, I'll finish up the process stuff and then merge it. Thanks again for contributing!
