BREAKING: Metrics removals and renames

[lauzadis]

An upcoming release of the AWS SDK for Kotlin removes and renames metrics namespaced under smithy.client.*.

If you do not use smithy.client.* metrics, this change should not affect you.

Release Date

This feature will ship with the v0.33.0-beta release planned for 10/26/2023.

What’s changing

All metrics under the smithy.client.* namespace are changing to smithy.client.call.*. The base metric names remain unchanged.

The following metrics are being removed entirely:

• smithy.client.request.size
• smithy.client.response.size
• smithy.client.retries

How to Migrate

If you are using smithy.client.* metrics, change your usage to smithy.client.call.*.

If you are using smithy.client.retries, you can calculate the same metric by subtracting one from smithy.client.call.attempts.

If you are using smithy.client.request.size or smithy.client.response.size, these metrics have been deemed unnecessary and no direct migration is offered. Consider using smithy.client.http.bytes_sent and smithy.client.http.bytes_received which offer a total count of bytes sent/received by the client.
