Bases: CfnResource

A CloudFormation AWS::CloudWatch::MetricStream.

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.

Create a new AWS::CloudWatch::MetricStream.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
firehose_arn (str) – 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.
output_format (str) – 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 . This parameter is required.
role_arn (str) – 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 firehose:PutRecord and firehose:PutRecordBatch permissions.
exclude_filters (Union[IResolvable, Sequence[Union[IResolvable, MetricStreamFilterProperty, Dict[str, Any]]], None]) – If you specify this parameter, the stream sends metrics from all metric namespaces except for the namespaces that you specify here. You cannot specify both IncludeFilters and ExcludeFilters in the same metric stream. When you modify the IncludeFilters or ExcludeFilters of an existing metric stream in any way, the metric stream is effectively restarted, so after such a change you will get only the datapoints that have a timestamp after the time of the update.
include_filters (Union[IResolvable, Sequence[Union[IResolvable, MetricStreamFilterProperty, Dict[str, Any]]], None]) – If you specify this parameter, the stream sends only the metrics from the metric namespaces that you specify here. You cannot specify both IncludeFilters and ExcludeFilters in the same metric stream. When you modify the IncludeFilters or ExcludeFilters of an existing metric stream in any way, the metric stream is effectively restarted, so after such a change you will get only the datapoints that have a timestamp after the time of the update.
include_linked_accounts_metrics (Union[bool, IResolvable, None]) – If you are creating a metric stream in a monitoring account, specify true to include metrics from source accounts that are linked to this monitoring account, in the metric stream. The default is false . For more information about linking accounts, see CloudWatch cross-account observability
name (Optional[str]) – 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.
statistics_configurations (Union[IResolvable, Sequence[Union[IResolvable, MetricStreamStatisticsConfigurationProperty, Dict[str, Any]]], None]) – 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 additional 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 additional statistics to stream for those metrics. The additional statistics that you can stream depend on the stream’s OutputFormat . If the OutputFormat is json , you can stream any additional statistic that is supported by CloudWatch , listed in CloudWatch statistics definitions . If the OutputFormat is opentelemetry0 .7, you can stream percentile statistics (p??) .
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – An array of key-value pairs to apply to the metric stream. For more information, see Tag .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters:

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Return type:

None

override_logical_id(new_logical_id)

Overrides the auto-generated logical ID with a specific ID.

Parameters:: new_logical_id (str) – The new logical ID to use for this stack element.
Return type:: None

to_string()

Returns a string representation of this construct.

Return type:: str
Returns:: a string representation of this resource

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

name

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.
