Logging AWS Config API Calls with AWS CloudTrail

AWS Config is integrated with AWS CloudTrail, a service that captures API calls made by or on behalf of AWS services in your AWS account and delivers the log files to an Amazon Simple Storage Service (S3) bucket that you specify. CloudTrail captures all API calls from the AWS Config console or from the AWS Config API. Using the information collected by CloudTrail, you can determine what request was made to AWS Config, the source IP address from which the 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.

AWS Config Information in CloudTrail

When enabled in your AWS account, CloudTrail tracks API calls made to AWS Config. AWS Config records are written together with other AWS service records in a log file. CloudTrail determines when to create and write to a new file based on a time period and file size.

All AWS Config operations are logged and are documented in the AWS Config API Reference. For example, calls to the DeliverConfigSnapshot, DeleteDeliveryChannel, and DescribeDeliveryChannels operations generate entries in the CloudTrail log files.

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

By default, your log files are encrypted by using Amazon S3 server-side encryption (SSE). You can store your log files in your bucket for as long as you want, but you can also define Amazon S3 lifecycle rules to archive or delete log files automatically. For information on setting up lifecycle rules, see Managing Lifecycle Configuration in the Amazon Simple Storage Service Console User Guide.

If you want to take quick action upon log file delivery, you can choose to have CloudTrail publish Amazon SNS notifications when new log files are delivered. For more information, see Configuring Amazon SNS Notifications.

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

Understanding AWS Config Log File Entries

CloudTrail log files can contain one or more log entries where each entry is made up of multiple JSON-formatted events. A log entry represents a single request from any source and includes information about the requested operation, any parameters, the date and time of the operation, and so on. The log entries are not guaranteed to be in any particular order. That is, they are not an ordered stack trace of the public API calls.

Example Log Files
