Logging Elastic Transcoder API Calls Using CloudTrail

Elastic Transcoder is integrated with CloudTrail, an AWS service that captures information about every request that is sent to the Elastic Transcoder API by your AWS account, including your IAM users. CloudTrail periodically saves log files of these requests to an Amazon S3 bucket that you specify. CloudTrail captures information about all requests, whether they were made using the Elastic Transcoder console, the Elastic Transcoder API, the AWS SDKs, the Elastic Transcoder CLI, or another service, for example, CloudFront.

You can use information in the CloudTrail log files to determine which requests were made to Elastic Transcoder, the source IP address from which each request was made, who made the request, when it was made, and so on. To learn more about CloudTrail, including how to configure and enable it, see the AWS CloudTrail User Guide.

Elastic Transcoder Information in CloudTrail Log Files

When you enable CloudTrail, CloudTrail captures every request that you make to every AWS service that CloudTrail supports. (For a list of supported services, see Supported Services in the AWS CloudTrail User Guide.) CloudTrail saves the captured requests in log files in each region separately, and stores them in an Amazon S3 bucket. The log files aren't organized or sorted by service; each log file might contain records from more than one service. CloudTrail determines when to create a new log file.

Note

CloudTrail supports all Elastic Transcoder API actions.

Every log file entry contains information about who made the request. The user identity information in the log file helps you determine whether the request was made using root or IAM user credentials, using temporary security credentials for a role or federated user, or by another AWS service. For more information, see userIdentity Element in the AWS CloudTrail User Guide.

You can store log files for as long as you want. You can also define Amazon S3 life cycle rules to archive or delete log files automatically.

By default, your log files are encrypted by using Amazon S3 server-side encryption (SSE).

You can choose to have CloudTrail publish Amazon SNS notifications when new log files are delivered if you want to take quick action upon log file delivery. For more information, see Configuring Amazon SNS Notifications in the AWS CloudTrail User Guide.

You can also aggregate log files from multiple AWS regions and multiple AWS accounts into a single Amazon S3 bucket. For more information, see Aggregating CloudTrail Log Files to a Single Amazon S3 Bucket in the AWS CloudTrail User Guide.

There is no cost to use the CloudTrail service. However, standard rates for Amazon S3 usage apply as well as rates for Amazon SNS usage should you include that option. For pricing details, see the Amazon S3 and Amazon SNS pricing pages.

Understanding Elastic Transcoder Log File Entries

Each JSON-formatted CloudTrail log file can contain one or more log entries. A log entry represents a single request from any source and includes information about the requested action, including any parameters, the date and time of the action, and so on. The log entries are not guaranteed to be in any particular order; they are not an ordered stack trace of API calls.

The eventSource element identifies the source of the action that occurred. For example, the following eventSource value indicates that Elastic Transcoder was called:

elastictranscoder.amazonaws.com

The eventName element identifies the action that occurred. For example, the following eventName value indicates that a job was created:

CreateJob

The following example shows a CloudTrail log entry that demonstrates five actions:

  • Creating a job. The value of eventName is CreateJob.

  • Listing jobs by status. The value of eventName is ListJobsByStatus.

  • Getting a job. The value of eventName is ReadJob.

  • Deleting a Preset. The value of eventName is DeletePreset.

  • Deleting a pipeline. The value of eventName is DeletePipeline.
