# Semantic Conventions for AWS S3 **Status**: [Experimental][DocumentStatus] The Semantic Conventions for AWS S3 extend the general [AWS SDK Semantic Conventions](/docs/cloud-providers/aws-sdk.md) that describe common AWS SDK attributes in addition to the Semantic Conventions described on this page. | Attribute | Type | Description | Examples | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Stability | |---|---|---|---|---|---| | [`rpc.system`](/docs/attributes-registry/rpc.md) | string | The value `aws-api`. | `aws-api` | `Required` |  | | [`aws.request_id`](/docs/attributes-registry/aws.md) | string | The AWS request ID as returned in the response headers `x-amz-request-id` or `x-amz-requestid`. | `79b9da39-b7ae-508a-a6bc-864b2829c622`; `C9ER4AJX75574TDJ` | `Recommended` |  | | [`aws.s3.bucket`](/docs/attributes-registry/aws.md) | string | The S3 bucket name the request refers to. Corresponds to the `--bucket` parameter of the [S3 API](https://docs.aws.amazon.com/cli/latest/reference/s3api/index.html) operations. [1] | `some-bucket-name` | `Recommended` |  | | [`aws.s3.copy_source`](/docs/attributes-registry/aws.md) | string | The source object (in the form `bucket`/`key`) for the copy operation. [2] | `someFile.yml` | `Recommended` |  | | [`aws.s3.delete`](/docs/attributes-registry/aws.md) | string | The delete request container that specifies the objects to be deleted. [3] | `Objects=[{Key=string,VersionId=string},{Key=string,VersionId=string}],Quiet=boolean` | `Recommended` |  | | [`aws.s3.key`](/docs/attributes-registry/aws.md) | string | The S3 object key the request refers to. Corresponds to the `--key` parameter of the [S3 API](https://docs.aws.amazon.com/cli/latest/reference/s3api/index.html) operations. [4] | `someFile.yml` | `Recommended` |  | | [`aws.s3.part_number`](/docs/attributes-registry/aws.md) | int | The part number of the part being uploaded in a multipart-upload operation. This is a positive integer between 1 and 10,000. [5] | `3456` | `Recommended` |  | | [`aws.s3.upload_id`](/docs/attributes-registry/aws.md) | string | Upload ID that identifies the multipart upload.

[8] | `DynamoDB`; `S3` | `Recommended` |  | **[1] `aws.s3.bucket`:** The `bucket` attribute is applicable to all S3 operations that reference a bucket, i.e. that require the bucket name as a mandatory parameter. This applies to almost all S3 operations except `list-buckets`. **[2] `aws.s3.copy_source`:** The `copy_source` attribute applies to S3 copy operations and corresponds to the `--copy-source` parameter of the [copy-object operation within the S3 API](https://docs.aws.amazon.com/cli/latest/reference/s3api/copy-object.html). This applies in particular to the following operations: - [copy-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/copy-object.html) - [upload-part-copy](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part-copy.html) **[3] `aws.s3.delete`:** The `delete` attribute is only applicable to the [delete-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/delete-object.html) operation. The `delete` attribute corresponds to the `--delete` parameter of the [delete-objects operation within the S3 API](https://docs.aws.amazon.com/cli/latest/reference/s3api/delete-objects.html). **[4] `aws.s3.key`:** The `key` attribute is applicable to all object-related S3 operations, i.e. that require the object key as a mandatory parameter. This applies in particular to the following operations: - [copy-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/copy-object.html) - [delete-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/delete-object.html) - [get-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/get-object.html) - [head-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/head-object.html) - [put-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/put-object.html) - [restore-object](https://docs.aws.amazon.com/cli/latest/reference/s3api/restore-object.html) - [select-object-content](https://docs.aws.amazon.com/cli/latest/reference/s3api/select-object-content.html) - [abort-multipart-upload](https://docs.aws.amazon.com/cli/latest/reference/s3api/abort-multipart-upload.html) - [complete-multipart-upload](https://docs.aws.amazon.com/cli/latest/reference/s3api/complete-multipart-upload.html) - [create-multipart-upload](https://docs.aws.amazon.com/cli/latest/reference/s3api/create-multipart-upload.html) - [list-parts](https://docs.aws.amazon.com/cli/latest/reference/s3api/list-parts.html) - [upload-part](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part.html) - [upload-part-copy](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part-copy.html) **[5] `aws.s3.part_number`:** The `part_number` attribute is only applicable to the [upload-part](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part.html) and [upload-part-copy](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part-copy.html) operations. The `part_number` attribute corresponds to the `--part-number` parameter of the [upload-part operation within the S3 API](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part.html). **[6] `aws.s3.upload_id`:** The `upload_id` attribute applies to S3 multipart-upload operations and corresponds to the `--upload-id` parameter of the [S3 API](https://docs.aws.amazon.com/cli/latest/reference/s3api/index.html) multipart operations. This applies in particular to the following operations: - [abort-multipart-upload](https://docs.aws.amazon.com/cli/latest/reference/s3api/abort-multipart-upload.html) - [complete-multipart-upload](https://docs.aws.amazon.com/cli/latest/reference/s3api/complete-multipart-upload.html) - [list-parts](https://docs.aws.amazon.com/cli/latest/reference/s3api/list-parts.html) - [upload-part](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part.html) - [upload-part-copy](https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part-copy.html) **[7] `rpc.method`:** This is the logical name of the method from the RPC interface perspective, which can be different from the name of any implementing method/function. The `code.function` attribute may be used to store the latter (e.g., method actually executing the call on the server side, RPC client stub method on the client side). **[8] `rpc.service`:** This is the logical name of the service from the RPC interface perspective, which can be different from the name of any implementing class. The `code.namespace` attribute may be used to store the latter (despite the attribute name, it may include a class name; e.g., class with method actually executing the call on the server side, RPC client stub class on the client side). --- `rpc.system` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used. | Value | Description | Stability | |---|---|---| | `apache_dubbo` | Apache Dubbo |  | | `connect_rpc` | Connect RPC |  | | `dotnet_wcf` | .NET WCF |  | | `grpc` | gRPC |  | | `java_rmi` | Java RMI |  | [DocumentStatus]: https://opentelemetry.io/docs/specs/otel/document-status
