Logging Amazon DataSync API calls with Amazon CloudTrail

Amazon DataSync is integrated with Amazon CloudTrail, a service that provides a record of actions taken by a user, role, or an Amazon Web Service in DataSync. CloudTrail captures all API calls for DataSync as events. The calls that are captured include calls from the DataSync console and code calls to DataSync API operations.

If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon S3 bucket, including events for Amazon DataSync. If you don't configure a trail, you can still view the most recent events in the CloudTrail console in Event history. Using the information collected by CloudTrail, you can determine the request that was made to Amazon DataSync, the IP address from which the request was made, who made the request, when it was made, and additional details.

To learn more about CloudTrail, see the Amazon CloudTrail User Guide.

Working with DataSync information in CloudTrail

CloudTrail is enabled on your Amazon Web Services account when you create the account. When activity occurs in Amazon DataSync, that activity is recorded in a CloudTrail event along with other Amazon Web Service events in Event history. You can view, search, and download recent events in your Amazon Web Services account. For more information, see Viewing events with CloudTrail event history.

For an ongoing record of events in your Amazon Web Services account, including events for Amazon DataSync, create a trail. A trail enables CloudTrail to deliver log files to an Amazon S3 bucket. By default, when you create a trail in the console, the trail applies to all Amazon Web Services Regions. The trail logs events from all Amazon Web Services Regions in the same Amazon partition and delivers the log files to the Amazon S3 bucket that you specify. Additionally, you can configure other Amazon Web Services to further analyze and act upon the event data collected in CloudTrail logs. For more information, see the following:

All DataSync actions are logged by CloudTrail. (For more information, see the DataSync API reference.)

For example, calls to the CreateAgent, CreateTask, and ListLocations operations generate entries in the CloudTrail log files.

Every event or log entry contains information about who generated the request. The identity information helps you determine the following:

  • Whether the request was made with root or Amazon Identity and Access Management (IAM) credentials.

  • Whether the request was made with temporary security credentials for a role or federated user.

  • Whether the request was made by another Amazon Web Service.

For more information, see CloudTrail userIdentity element in the Amazon CloudTrail User Guide.

Understanding DataSync log file entries

A trail is a configuration that enables delivery of events as log files to an Amazon S3 bucket that you specify. CloudTrail log files contain one or more log entries. An event represents a single request from any source and includes information about the requested action, the date and time of the action, the request parameters, and so on. CloudTrail log files aren't an ordered stack trace of the public API calls, so they don't appear in any specific order.

The following example shows a CloudTrail log entry that demonstrates the CreateTask operation.
