CfnLoggerDefinition

class aws_cdk.aws_greengrass.CfnLoggerDefinition(scope, id, *, name, initial_version=None, tags=None)

Bases: CfnResource

A CloudFormation AWS::Greengrass::LoggerDefinition.

The AWS::Greengrass::LoggerDefinition resource represents a logger definition for AWS IoT Greengrass . Logger definitions are used to organize your logger definition versions.

Logger definitions can reference multiple logger definition versions. All logger definition versions must be associated with a logger definition. Each logger definition version can contain one or more loggers. .. epigraph:

When you create a logger definition, you can optionally include an initial logger definition version. To associate a logger definition version later, create an ```AWS::Greengrass::LoggerDefinitionVersion`` <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-loggerdefinitionversion.html>`_ resource and specify the ID of this logger definition.

After you create the logger definition version that contains the loggers you want to deploy, you must add it to your group version. For more information, see ```AWS::Greengrass::Group`` <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-group.html>`_ .

    ),
    tags=tags
)

Create a new AWS::Greengrass::LoggerDefinition.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
name (str) – The name of the logger definition.
initial_version (Union[IResolvable, LoggerDefinitionVersionProperty, Dict[str, Any], None]) – The logger definition version to include when the logger definition is created. A logger definition version contains a list of `logger <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-greengrass-loggerdefinition-logger.html>`_ property types. .. epigraph:: To associate a logger definition version after the logger definition is created, create an `AWS::Greengrass::LoggerDefinitionVersion <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-loggerdefinitionversion.html>`_ resource and specify the ID of this logger definition.
tags (Optional[Any]) – Application-specific metadata to attach to the logger definition. You can use tags in IAM policies to control access to AWS IoT Greengrass resources. You can also use tags to categorize your resources. For more information, see Tagging Your AWS IoT Greengrass Resources in the Developer Guide . This Json property type is processed as a map of key-value pairs. It uses the following format, which is different from most Tags implementations in AWS CloudFormation templates:: “Tags”: { “KeyName0”: “value”, “KeyName1”: “value”, “KeyName2”: “value” }

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

class CfnLoggerDefinition.LoggerProperty(*, component, id, level, type, space=None)

Bases: object

A logger represents logging settings for the AWS IoT Greengrass group, which can be stored in CloudWatch and the local file system of your core device.

All log entries include a timestamp, log level, and information about the event. For more information, see Monitoring with AWS IoT Greengrass Logs in the Developer Guide .

In an AWS CloudFormation template, the Loggers property of the `LoggerDefinitionVersion <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-greengrass-loggerdefinition-loggerdefinitionversion.html>`_ property type contains a list of Logger property types.

Parameters:

component (str) – The source of the log event. Valid values are GreengrassSystem or Lambda . When GreengrassSystem is used, events from Greengrass system components are logged. When Lambda is used, events from user-defined Lambda functions are logged.
id (str) – A descriptive or arbitrary ID for the logger. This value must be unique within the logger definition version. Maximum length is 128 characters with pattern [a-zA-Z0-9:_-]+ .
level (str) – The log-level threshold. Log events below this threshold are filtered out and aren’t stored. Valid values are DEBUG , INFO (recommended), WARN , ERROR , or FATAL .
type (str) – The storage mechanism for log events. Valid values are FileSystem or AWSCloudWatch . When AWSCloudWatch is used, log events are sent to CloudWatch Logs . When FileSystem is used, log events are stored on the local file system.
space (Union[int, float, None]) – The amount of file space (in KB) to use when writing logs to the local file system. This property does not apply for CloudWatch Logs .
