AWS CloudTrail

This is the CloudTrail API Reference. It provides descriptions of actions, data types, common parameters, and common errors for CloudTrail.

CloudTrail is a web service that records AWS API calls for your AWS account and delivers log files to an Amazon S3 bucket. The recorded information includes the identity of the user, the start time of the AWS API call, the source IP address, the request parameters, and the response elements returned by the service.

As an alternative to the API, you can use one of the AWS SDKs, which consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .NET, iOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to AWSCloudTrail. For example, the SDKs take care of cryptographically signing requests, managing errors, and retrying requests automatically. For information about the AWS SDKs, including how to download and install them, see the Tools for Amazon Web Services page.

See the CloudTrail User Guide for information about the data that is included with each AWS API call listed in the log files.

      public GetTrailStatusResult getTrailStatus(GetTrailStatusRequest getTrailStatusRequest)

      Returns a JSON-formatted list of information about the specified trail. Fields include information on delivery errors, Amazon SNS and Amazon S3 errors, and start and stop logging times for each trail. This operation returns trail status from a single region. To return trail status from all regions, you must call the operation on each region.

      Specified by:
      getTrailStatus in interface AWSCloudTrail
      Parameters:
      getTrailStatusRequest - The name of a trail about which you want the current status.

    • lookupEvents

      public LookupEventsResult lookupEvents(LookupEventsRequest lookupEventsRequest)

      Looks up API activity events captured by CloudTrail that create, update, or delete resources in your account. Events for a region can be looked up for the times in which you had CloudTrail turned on in that region during the last seven days. Lookup supports five different attributes: time range (defined by a start time and end time), user name, event name, resource type, and resource name. All attributes are optional. The maximum number of attributes that can be specified in any one lookup request are time range and one other attribute. The default number of results returned is 10, with a maximum of 50 possible. The response includes a token that you can use to get the next page of results.

      The rate of lookup requests is limited to one per second per account. If this limit is exceeded, a throttling error occurs.

      Events that occurred during the selected time range will not be available for lookup if CloudTrail logging was not enabled when the events occurred.

      Specified by:
      lookupEvents in interface AWSCloudTrail
      Parameters:
      lookupEventsRequest - Contains a request for LookupEvents.

      InvalidMaxResultsException - This exception is thrown if the limit specified is invalid.
      InvalidNextTokenException - Invalid token or token that was previously used in a request with different parameters. This exception is thrown if the token is invalid.

    • startLogging

      public StartLoggingResult startLogging(StartLoggingRequest startLoggingRequest)

      Starts the recording of AWS API calls and log file delivery for a trail. For a trail that is enabled in all regions, this operation must be called from the region in which the trail was created.

For a trail enabled in all regions, this operation must be called from the region in which the trail was created, or an InvalidHomeRegionException will occur. This operation cannot be called on the shadow trails (replicated trails in other regions) of a trail enabled in all regions.

      Specified by:
      stopLogging in interface AWSCloudTrail
      Parameters:

If the existing bucket has previously been a target for CloudTrail log files, an IAM policy exists for the bucket. UpdateTrail must be called from the region in which the trail was created; otherwise, an InvalidHomeRegionException is thrown.

      public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
      Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

      Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

      request - The originally executed request

      The response metadata for the specified request, or null if none is available.
