describe-stream-summary

Description

Provides a summarized description of the specified Kinesis data stream without the shard list.

The information returned includes the stream name, Amazon Resource Name (ARN), status, record retention period, approximate creation time, monitoring, encryption details, and open shard count.

DescribeStreamSummary has a limit of 20 transactions per second per account.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-stream-summary
--stream-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--stream-name (string)

The name of the stream to describe.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To describe a data stream summary

The following describe-stream-summary example provides a summarized description (without the shard list) of the specified data stream.

aws kinesis describe-stream-summary \
    --stream-name samplestream

Output:

{
    "StreamDescriptionSummary": {
        "StreamName": "samplestream",
        "StreamARN": "arn:aws:kinesis:us-west-2:123456789012:stream/samplestream",
        "StreamStatus": "ACTIVE",
        "RetentionPeriodHours": 48,
        "StreamCreationTimestamp": 1572297168.0,
        "EnhancedMonitoring": [
            {

Output

StreamDescriptionSummary -> (structure)

A StreamDescriptionSummary containing information about the stream.

StreamName -> (string)

The name of the stream being described.

StreamARN -> (string)

The Amazon Resource Name (ARN) for the stream being described.

StreamStatus -> (string)

The current status of the stream being described. The stream status is one of the following states:

• CREATING - The stream is being created. Kinesis Data Streams immediately returns and sets StreamStatus to CREATING .

• DELETING - The stream is being deleted. The specified stream is in the DELETING state until Kinesis Data Streams completes the deletion.

• ACTIVE - The stream exists and is ready for read and write operations or deletion. You should perform read and write operations only on an ACTIVE stream.

• UPDATING - Shards in the stream are being merged or split. Read and write operations continue to work while the stream is in the UPDATING state.

RetentionPeriodHours -> (integer)

The current retention period, in hours.

StreamCreationTimestamp -> (timestamp)

The approximate time that the stream was created.

EnhancedMonitoring -> (list)

Represents the current enhanced monitoring settings of the stream.

(structure)

Represents enhanced metrics types.

ShardLevelMetrics -> (list)

List of shard-level metrics.

The following are the valid shard-level metrics. The value “ALL ” enhances every metric.

• IncomingBytes

• IncomingRecords

• OutgoingBytes

• OutgoingRecords

• WriteProvisionedThroughputExceeded

• ReadProvisionedThroughputExceeded

• IteratorAgeMilliseconds

• ALL

For more information, see Monitoring the Amazon Kinesis Data Streams Service with Amazon CloudWatch in the Amazon Kinesis Data Streams Developer Guide .

(string)

EncryptionType -> (string)

The encryption type used. This value is one of the following:

• KMS

• NONE

KeyId -> (string)

The GUID for the customer-managed AWS KMS key to use for encryption. This value can be a globally unique identifier, a fully specified ARN to either an alias or a key, or an alias name prefixed by “alias/”.You can also use a master key owned by Kinesis Data Streams by specifying the alias aws/kinesis .

• Key ARN example: arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012

• Alias ARN example: arn:aws:kms:us-east-1:123456789012:alias/MyAliasName

• Globally unique key ID example: 12345678-1234-1234-1234-123456789012

• Alias name example: alias/MyAliasName

• Master key owned by Kinesis Data Streams: alias/aws/kinesis

OpenShardCount -> (integer)

The number of open shards in the stream.

ConsumerCount -> (integer)

The number of enhanced fan-out consumers registered with the stream.
