StartExportTask - AWS Application Discovery Service


Begins the export of a discovered data report to an Amazon S3 bucket managed by AWS.


Exports might provide an estimate of fees and savings based on certain information that you provide. Fee estimates do not include any taxes that might apply. Your actual fees and savings depend on a variety of factors, including your actual usage of AWS services, which might vary from the estimates provided in this report.

If you do not specify preferences or agentIds in the filter, a summary of all servers, applications, tags, and performance is generated. This data is an aggregation of all server data collected through on-premises tooling, file import, application grouping and applying tags.

If you specify agentIds in a filter, the task exports up to 72 hours of detailed data collected by the identified Application Discovery Agent, including network, process, and performance details. A time range for exported agent data may be set by using startTime and endTime. Export of detailed agent data is limited to five concurrently running exports. Export of detailed agent data is limited to two exports per day.

If you enable ec2RecommendationsPreferences in preferences ExportPreferences, an Amazon EC2 instance matching the characteristics of each server in Application Discovery Service is generated. Changing the attributes of the ec2RecommendationsPreferences changes the criteria of the recommendation.

If no filter is present, startTime and endTime are ignored and exported data includes both AWS Application Discovery Service Agentless Collector collectors data and summary data from Application Discovery Agent agents.

Type: Array of ExportFilter objects

Required: No


Indicates the type of data that needs to be exported. Only one ExportPreferences can be enabled at any time.

Type: ExportPreferences object

Note: This object is a Union. Only one member of this object can be specified or returned.

In the following example or examples, the Authorization header contents (AUTHPARAMS) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see Signature Version 4 Signing Process in the AWS General Reference.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.
