Creates or updates a metric stream. Metric streams can automatically stream CloudWatch metrics to Amazon Web Services destinations including Amazon S3 and to many third-party solutions.

For more information, see Using Metric Streams .

To create a metric stream, you must be logged on to an account that has the iam:PassRole permission and either the CloudWatchFullAccess policy or the cloudwatch:PutMetricStream permission.

When you create or update a metric stream, you choose one of the following:

  • Stream metrics from all metric namespaces in the account.

  • Stream metrics from all metric namespaces in the account, except for the namespaces that you list in ExcludeFilters .

  • Stream metrics from only the metric namespaces that you list in IncludeFilters .

By default, a metric stream always sends the MAX , MIN , SUM , and SAMPLECOUNT statistics for each metric that is streamed. You can use the StatisticsConfigurations parameter to have the metric stream also send extended statistics in the stream. Streaming extended statistics incurs additional costs. For more information, see Amazon CloudWatch Pricing .

When you use PutMetricStream to create a new metric stream, the stream is created in the running state. If you use it to update an existing stream, the state of the stream is not changed.

type Name

string

param Name

[REQUIRED]

If you are creating a new metric stream, this is the name for the new stream. The name must be different than the names of other metric streams in this account and Region.

If you are updating a metric stream, specify the name of that stream here.

Valid characters are A-Z, a-z, 0-9, "-" and "_".

type IncludeFilters

list

param IncludeFilters

If you specify this parameter, the stream sends only the metrics from the metric namespaces that you specify here.

You cannot include IncludeFilters and ExcludeFilters in the same operation.

  • (dict) --

    This structure contains the name of one of the metric namespaces that is listed in a filter of a metric stream.

    • Namespace (string) --

      The name of the metric namespace in the filter.

type ExcludeFilters

list

param ExcludeFilters

If you specify this parameter, the stream sends metrics from all metric namespaces except for the namespaces that you specify here.

You cannot include ExcludeFilters and IncludeFilters in the same operation.

  • (dict) --

    This structure contains the name of one of the metric namespaces that is listed in a filter of a metric stream.

    • Namespace (string) --

      The name of the metric namespace in the filter.

type FirehoseArn

string

param FirehoseArn

[REQUIRED]

The ARN of the Amazon Kinesis Firehose delivery stream to use for this metric stream. This Amazon Kinesis Firehose delivery stream must already exist and must be in the same account as the metric stream.

type RoleArn

string

param RoleArn

[REQUIRED]

The ARN of an IAM role that this metric stream will use to access Amazon Kinesis Firehose resources. This IAM role must already exist and must be in the same account as the metric stream. This IAM role must include the following permissions:

  • firehose:PutRecord

  • firehose:PutRecordBatch

type OutputFormat

string

param OutputFormat

[REQUIRED]

The output format for the stream. Valid values are json and opentelemetry0.7 . For more information about metric stream output formats, see Metric streams output formats .

type Tags

list

param Tags

A list of key-value pairs to associate with the metric stream. You can associate as many as 50 tags with a metric stream.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.

You can use this parameter only when you are creating a new metric stream. If you are using this operation to update an existing metric stream, any tags you specify in this parameter are ignored. To change the tags of an existing metric stream, use TagResource or UntagResource .

  • (dict) --

    A key-value pair associated with a CloudWatch resource.

    • Key (string) -- [REQUIRED]

      A string that you can use to assign a value. The combination of tag keys and values can help you organize and categorize your resources.

    • Value (string) -- [REQUIRED]

      The value for the specified tag key.

type StatisticsConfigurations

list

param StatisticsConfigurations

By default, a metric stream always sends the MAX , MIN , SUM , and SAMPLECOUNT statistics for each metric that is streamed. You can use this parameter to have the metric stream also send extended statistics in the stream. This array can have up to 100 members.

For each entry in this array, you specify one or more metrics and the list of extended statistics to stream for those metrics. The extended statistics that you can stream depend on the stream's OutputFormat . If the OutputFormat is json , you can stream any extended statistic that is supported by CloudWatch, listed in CloudWatch statistics definitions . If the OutputFormat is opentelemetry0.7 , you can stream percentile statistics (p*??* ).

  • (dict) --
