Logging AWS Elemental MediaPackage API calls with AWS CloudTrail

Logging is available with only live workflows in AWS Elemental MediaPackage.

MediaPackage is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service in MediaPackage. CloudTrail captures all API calls for MediaPackage as events. These include calls from the MediaPackage console and code calls to the MediaPackage API operations. If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon S3 bucket, including events for MediaPackage. 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 MediaPackage, 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 AWS CloudTrail User Guide.

AWS Elemental MediaPackage information in CloudTrail

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

For an ongoing record of events in your account, including events for MediaPackage, 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 AWS Regions. The trail logs events from all AWS Regions in the AWS partition and delivers the log files to the Amazon S3 bucket that you specify. Additionally, you can configure other AWS services to further analyze and act upon the event data collected in CloudTrail logs. For more information, see the following:

• Overview for creating a trail

• CloudTrail supported services and integrations

• Configuring Amazon SNS notifications for CloudTrail

• Receiving CloudTrail log files from multiple regions and Receiving CloudTrail log files from multiple accounts

All MediaPackage actions are logged by CloudTrail and are documented in the AWS Elemental MediaPackage API Reference. For example, calls to the CreateChannel, CreateOriginEndpoint, and RotateIngestEndpointCredentials 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 user or IAM user credentials

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

• Whether the request was made by another AWS service

For more information, see the CloudTrail userIdentity element.

Understanding AWS Elemental MediaPackage 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, 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 UpdateChannel operation:
