CfnMetricStreamPropsMixin Mixin ​

Creates or updates a metric stream.

Metrics streams can automatically stream CloudWatch metrics to AWS destinations including Amazon S3 and to many third-party solutions. For more information, see 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 .

When you create a metric stream, the stream is created in the running state. If you update an existing metric stream, the state does not change.

If you create a metric stream in an account that has been set up as a monitoring account in CloudWatch cross-account observability, you can choose whether to include metrics from linked source accounts in the metric stream.
