I have contacted AWS Support to help resolve an issue with Amazon Simple Storage Service (Amazon S3). How do I generate information for the AWS Support team to most effectively troubleshoot this issue?

Amazon S3 generates a pair of request IDs for each request that it processes. When you contact AWS Support for help in troubleshooting Amazon S3, you need to provide the values of the S3 request ID pair associated with any failed actions. This information helps AWS Support identify and troubleshoot your issue as quickly as possible.

Amazon S3 request ID pairs are accessible from HTTP headers and verbose logs using several different methods, including using AWS CloudTrail to log Amazon S3 API calls. For more information about how to retrieve Amazon S3 request ID pairs, see Getting my Amazon S3 request IDs. The names used to describe each half of an S3 request ID pair can vary, depending on how the S3 request ID pairs are retrieved. This table lists three commonly used methods for retrieving S3 request ID pairs and the corresponding names used for each half:

Access method

First name in pair

Second name in pair

HTTP response header

x-amz-request-id

x-amz-id-2

HTTP response body
(returned on errors only)

RequestId

HostId

AWS SDK request

AWS Request ID

S3 Extended Request ID

For example, an S3 request ID pair returned in an HTTP request header resembles the following:

x-amz-request-id: 79104EXAMPLEB723
x-amz-id-2: IOWQ4fDEXAMPLEQM+ey7N9WgVhSnQ6JEXAMPLEZb7hSQDASK+Jd1vEXAMPLEa3Km

Important: Be sure to provide both values of an S3 request ID pair when requested.

For more information about using CloudTrail data event logging to retrieve request id pairs, see Logging Amazon S3 API Calls By Using AWS CloudTrail. CloudTrail data event logging for S3 objects retrieves both Request ID and Extended request ID data.
