@jake-engelberg - I realize that we need to make error codes concept much more visible to developers by adding a topic under https://docs.dapr.io/developing-applications/building-blocks/ called "API Error codes" describing what they are and also how you can get metrics for them (This can point to the error codes list and the metrics configuration)

Also in this article we should mention that each SDK can handle and return the error code in the language specific way. For example this is Go https://docs.dapr.io/developing-applications/sdks/go/go-client/#error-handling but we also need to discuss with each of the SDK maintainers how to handle these. I suggest raising an issue into each of SDK repos for this to track this (if my understanding is correct)

@hhunter-ms can help as needed. Hannah - This reference article https://docs.dapr.io/reference/api/error_codes/ should be called "API Error codes" in the index file. I did not realize this was buried under Dapr API reference.

@jake-engelberg this is HTTP and gRPC?

[jake-engelberg]

Yes, it is both and we'll update the wording soon to reflect the auto generated chart with both codes which at the moment sometimes differ:

dapr/dapr#8346

You also need to;

1. update this table in configuration setting https://docs.dapr.io/operations/configuration/configuration-overview/#metrics And in that table point to this article for the details.
2. Update the configuration schema to add this under metrics section here https://docs.dapr.io/reference/resource-specs/configuration-schema/

@hhunter-ms - Will do this. Do Jake you can ignore this comment.
