describe-task-execution

Description

Returns detailed metadata about a task that is being executed.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  describe-task-execution
--task-execution-arn <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--task-execution-arn (string)

The Amazon Resource Name (ARN) of the task that is being executed.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

TaskExecutionArn -> (string)

The Amazon Resource Name (ARN) of the task execution that was described. TaskExecutionArn is hierarchical and includes TaskArn for the task that was executed.

For example, a TaskExecution value with the ARN arn:aws:datasync:us-east-1:111222333444:task/task-0208075f79cedf4a2/execution/exec-08ef1e88ec491019b executed the task with the ARN arn:aws:datasync:us-east-1:111222333444:task/task-0208075f79cedf4a2 .

Status -> (string)

The status of the task execution.

For detailed information about task execution statuses, see Understanding Task Statuses in the AWS DataSync User Guide.

Options -> (structure)

Represents the options that are available to control the behavior of a StartTaskExecution operation. Behavior includes preserving metadata such as user ID (UID), group ID (GID), and file permissions, and also overwriting files in the destination, data integrity verification, and so on.

A task has a set of default options associated with it. If you don't specify an option in StartTaskExecution , the default value is used. You can override the defaults options on each task execution by specifying an overriding Options value to StartTaskExecution .

VerifyMode -> (string)

A value that determines whether a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred.

Default value: POINT_IN_TIME_CONSISTENT.

POINT_IN_TIME_CONSISTENT: Perform verification (recommended).

NONE: Skip verification.

Atime -> (string)

A file metadata value that shows the last time a file was accessed (that is, when the file was read or written to). If you set Atime to BEST_EFFORT, DataSync attempts to preserve the original Atime attribute on all source files (that is, the version before the PREPARING phase). However, Atime 's behavior is not fully standard across platforms, so AWS DataSync can only do this on a best-effort basis.

Default value: BEST_EFFORT.

BEST_EFFORT: Attempt to preserve the per-file Atime value (recommended).

NONE: Ignore Atime .

Note

If Atime is set to BEST_EFFORT, Mtime must be set to PRESERVE.

If Atime is set to NONE, Mtime must also be NONE.

Mtime -> (string)

A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase.

Default value: PRESERVE.

PRESERVE: Preserve original Mtime (recommended)

NONE: Ignore Mtime .

Note

If Mtime is set to PRESERVE, Atime must be set to BEST_EFFORT.

If Mtime is set to NONE, Atime must also be set to NONE.

Uid -> (string)

The user ID (UID) of the file's owner.

Default value: INT_VALUE. This preserves the integer value of the ID.

INT_VALUE: Preserve the integer value of UID and group ID (GID) (recommended).

NONE: Ignore UID and GID.

Gid -> (string)

The group ID (GID) of the file's owners.

Default value: INT_VALUE. This preserves the integer value of the ID.

INT_VALUE: Preserve the integer value of user ID (UID) and GID (recommended).

NONE: Ignore UID and GID.

PreserveDeletedFiles -> (string)

A value that specifies whether files in the destination that don't exist in the source file system should be preserved.

Default value: PRESERVE.

PRESERVE: Ignore such destination files (recommended).

REMOVE: Delete destination files that aren’t present in the source.

PreserveDevices -> (string)

A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and recreate the files with that device name and metadata on the destination.

Note

AWS DataSync can't sync the actual contents of such devices, because they are nonterminal and don't return an end-of-file (EOF) marker.

Default value: NONE.

NONE: Ignore special devices (recommended).

PRESERVE: Preserve character and block device metadata. This option isn't currently supported for Amazon EFS.

PosixPermissions -> (string)

A value that determines which users or groups can access a file for a specific purpose such as reading, writing, or execution of the file.

Default value: PRESERVE.

PRESERVE: Preserve POSIX-style permissions (recommended).

NONE: Ignore permissions.

Note

AWS DataSync can preserve extant permissions of a source location.

BytesPerSecond -> (long)

A value that limits the bandwidth used by AWS DataSync. For example, if you want AWS DataSync to use a maximum of 1 MB, set this value to 1048576 (=1024*1024 ).

Excludes -> (list)

A list of filter rules that determines which files to exclude from a task. The list should contain a single filter string that consists of the patterns to exclude. The patterns are delimited by "|" (that is, a pipe), for example: "/folder1|/folder2"

(structure)

Specifies which files, folders and objects to include or exclude when transferring files from source to destination.

FilterType -> (string)

The type of filter rule to apply. AWS DataSync only supports the SIMPLE_PATTERN rule type.

Value -> (string)

A single filter string that consists of the patterns to include or exclude. The patterns are delimited by "|" (that is, a pipe), for example: /folder1|/folder2

Includes -> (list)

A list of filter rules that determines which files to include when running a task. The list should contain a single filter string that consists of the patterns to include. The patterns are delimited by "|" (that is, a pipe), for example: "/folder1|/folder2"

(structure)

Specifies which files, folders and objects to include or exclude when transferring files from source to destination.

FilterType -> (string)

The type of filter rule to apply. AWS DataSync only supports the SIMPLE_PATTERN rule type.

Value -> (string)

A single filter string that consists of the patterns to include or exclude. The patterns are delimited by "|" (that is, a pipe), for example: /folder1|/folder2

StartTime -> (timestamp)

The time that the task execution was started.

EstimatedFilesToTransfer -> (long)

The expected number of files that is to be transferred over the network. This value is calculated during the PREPARING phase, before the TRANSFERRING phase. This value is the expected number of files to be transferred. It's calculated based on comparing the content of the source and destination locations and finding the delta that needs to be transferred.

EstimatedBytesToTransfer -> (long)

The estimated physical number of bytes that is to be transferred over the network.

FilesTransferred -> (long)

The actual number of files that was transferred over the network. This value is calculated and updated on an ongoing basis during the TRANSFERRING phase. It's updated periodically when each file is read from the source and sent over the network.

If failures occur during a transfer, this value can be less than EstimatedFilesToTransfer . This value can also be greater than EstimatedFilesTransferred in some cases. This element is implementation-specific for some location types, so don't use it as an indicator for a correct file number or to monitor your task execution.

BytesWritten -> (long)

The number of logical bytes written to the destination AWS storage resource.

BytesTransferred -> (long)

The physical number of bytes transferred over the network.

Result -> (structure)

The result of the task execution.

PrepareDuration -> (long)

The total time in milliseconds that AWS DataSync spent in the PREPARING phase.

PrepareStatus -> (string)

The status of the PREPARING phase.

TransferDuration -> (long)

The total time in milliseconds that AWS DataSync spent in the TRANSFERRING phase.

TransferStatus -> (string)

The status of the TRANSFERRING Phase.

VerifyDuration -> (long)

The total time in milliseconds that AWS DataSync spent in the VERIFYING phase.

VerifyStatus -> (string)

The status of the VERIFYING Phase.

ErrorCode -> (string)

Errors that AWS DataSync encountered during execution of the task. You can use this error code to help troubleshoot issues.

ErrorDetail -> (string)

Detailed description of an error that was encountered during the task execution. You can use this information to help troubleshoot issues.
