# describe-sessions ## Description Retrieves a list that describes the streaming sessions for a specified stack and fleet. If a UserId is provided for the stack and fleet, only streaming sessions for that user are described. If an authentication type is not provided, the default is to authenticate users using a streaming URL. See also: [AWS API Documentation](https://docs.aws.amazon.com/goto/WebAPI/appstream-2016-12-01/DescribeSessions) `describe-sessions` is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the `--no-paginate` argument. When using `--output text` and the `--query` argument on a paginated response, the `--query` argument must extract data from the results of the following query expressions: `Sessions` ## Synopsis ``` describe-sessions --stack-name --fleet-name [--user-id ] [--authentication-type ] [--instance-id ] [--starting-token ] [--page-size ] [--max-items ] [--cli-input-json | --cli-input-yaml] [--generate-cli-skeleton ] [--debug] [--endpoint-url ] [--no-verify-ssl] [--no-paginate] [--output ] [--query ] [--profile ] [--region ] [--version ] [--color ] [--no-sign-request] [--ca-bundle ] [--cli-read-timeout ] [--cli-connect-timeout ] [--cli-binary-format ] [--no-cli-pager] [--cli-auto-prompt] [--no-cli-auto-prompt] [--cli-error-format ] ``` ## Options `--stack-name` (string) [required] > The name of the stack.

This value is case-sensitive. > Constraints: > * pattern: `^[a-zA-Z0-9][a-zA-Z0-9_.-]{0,100}$` `--user-id` (string) > The user identifier (ID). If you specify a user ID, you must also specify the authentication type. > Constraints: > * min: `2` > * max: `128` `--authentication-type` (string) > The authentication method. Specify `API` for a user authenticated using a streaming URL or `SAML` for a SAML federated user. The default is to authenticate users using a streaming URL. > Possible values: > * `API` > * `SAML` > * `USERPOOL` > * `AWS_AD` `--instance-id` (string) > The identifier for the instance hosting the session. > Constraints: > * min: `1` `--starting-token` (string) > A token to specify where to start paginating. This is the `NextToken` from a previously truncated response. > For usage examples, see [Pagination](https://docs.aws.amazon.com/cli/latest/userguide/pagination.html) in the *AWS Command Line Interface User Guide* . `--page-size` (integer) > The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out. > For usage examples, see [Pagination](https://docs.aws.amazon.com/cli/latest/userguide/pagination.html) in the *AWS Command Line Interface User Guide* . `--max-items` (integer) > The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a `NextToken` is provided in the command’s output. To resume pagination, provide the `NextToken` value in the `starting-token` argument of a subsequent command. **Do not** use the `NextToken` response element directly outside of the AWS CLI. > For usage examples, see [Pagination](https://docs.aws.amazon.com/cli/latest/userguide/pagination.html) in the *AWS Command Line Interface User Guide* . `--cli-input-json` | `--cli-input-yaml` (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by `--generate-cli-skeleton`. If other arguments are provided on the command line, those 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. This may not be specified along with `--cli-input-yaml`. `--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`. Similarly, if provided `yaml-input` it will print a sample input YAML that can be used with `--cli-input-yaml`. If provided with the value `output`, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated. ## Global Options `--debug` (boolean) Turn on debug logging. `--endpoint-url` (string) Override command’s default URL with the given URL. `--no-verify-ssl` (boolean) By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates. `--no-paginate` (boolean) Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results. `--output` (string) The formatting style for command output. * json * text * table * yaml * yaml-stream * off `--query` (string) A JMESPath query to use in filtering the response data. `--profile` (string) Use a specific profile from your credential file. `--region` (string) The region to use. Overrides config/env settings. `--version` (string) Display the version of this tool. `--color` (string) Turn on/off color output. * on * off * auto `--no-sign-request` (boolean) Do not sign requests. Credentials will not be loaded if this argument is provided. `--ca-bundle` (string) The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings. `--cli-read-timeout` (int) The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds. `--cli-connect-timeout` (int) The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds. `--cli-binary-format` (string) The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob `fileb://` will always be treated as binary and use the file contents directly regardless of the `cli-binary-format` setting. When using `file://` the file contents will need to properly formatted for the configured `cli-binary-format`. * base64 * raw-in-base64-out `--no-cli-pager` (boolean) Disable cli pager for output. `--cli-auto-prompt` (boolean) Automatically prompt for CLI input parameters. `--no-cli-auto-prompt` (boolean) Disable automatically prompt for CLI input parameters. `--cli-error-format` (string) The formatting style for error output. By default, errors are displayed in enhanced format. * legacy * json * yaml * text * table * enhanced ## Output Sessions -> (list) > Information about the streaming sessions. > (structure) > > Describes a streaming session. > > Id -> (string) [required] > > > The identifier of the streaming session. > > > Constraints: > > > * min: `1` > > UserId -> (string) [required] > > > The identifier of the user for whom the session was created. > > > Constraints: > > > * min: `2` > > > * max: `128` > > StackName -> (string) [required] > > > The name of the stack for the streaming session. > > > Constraints: > > > * min: `1` > > FleetName -> (string) [required] > > > The name of the fleet for the streaming session. > > > Constraints: > > > * min: `1` > > State -> (string) [required] > > > The current state of the streaming session. > > > Possible values: > > > * `ACTIVE` > > > * `PENDING` > > > * `EXPIRED` > > ConnectionState -> (string) > > > Specifies whether a user is connected to the streaming session. > > > Possible values: > > > * `CONNECTED` > > > * `NOT_CONNECTED` > > StartTime -> (timestamp) > > > The time when a streaming instance is dedicated for the user. > > MaxExpirationTime -> (timestamp) > > > The time when the streaming session is set to expire. This time is based on the `MaxUserDurationinSeconds` value, which determines the maximum length of time that a streaming session can run. A streaming session might end earlier than the time specified in `SessionMaxExpirationTime` , when the `DisconnectTimeOutInSeconds` elapses or the user chooses to end his or her session. If the `DisconnectTimeOutInSeconds` elapses, or the user chooses to end his or her session, the streaming instance is terminated and the streaming session ends. > > AuthenticationType -> (string) > > > The authentication method.
