LogRetention
- class aws_cdk.aws_logs.LogRetention(scope, id, *, log_group_name, retention, log_group_region=None, log_retention_retry_options=None, removal_policy=None, role=None)
Bases:
Construct
Creates a custom resource to control the retention policy of a CloudWatch Logs log group.
The log group is created if it doesn’t already exist. The policy is removed when
retentionDays
isundefined
or equal toInfinity
. Log group can be created in the region that is different from stack region by specifyinglogGroupRegion

Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. import aws_cdk as cdk from aws_cdk import aws_iam as iam from aws_cdk import aws_logs as logs # role: iam.Role log_retention = logs.LogRetention(self, "MyLogRetention", log_group_name="logGroupName", retention=logs.RetentionDays.ONE_DAY, # the properties below are optional log_group_region="logGroupRegion", log_retention_retry_options=logs.LogRetentionRetryOptions( base=cdk.Duration.minutes(30), max_retries=123 ), removal_policy=cdk.RemovalPolicy.DESTROY, role=role )
- Parameters:
scope (
Construct
) –id (
str
) –log_group_name (
str
) – The log group name.retention (
RetentionDays
) – The number of days log events are kept in CloudWatch Logs.log_group_region (
Optional
[str
]) – The region where the log group should be created. Default: - same region as the stacklog_retention_retry_options (
Union
[LogRetentionRetryOptions
,Dict
[str
,Any
],None
]) – Retry options for all AWS API calls. Default: - AWS SDK default retry optionsremoval_policy (
Optional
[RemovalPolicy
]) – The removalPolicy for the log group when the stack is deleted. Default: RemovalPolicy.RETAINrole (
Optional
[IRole
]) – The IAM role for the Lambda function associated with the custom resource. Default: - A new role is created
Methods

- Return type:
str
Attributes

The tree node.
Static Methods
- classmethod is_construct(x)
Checks if
x
is a construct.Use this method instead of
instanceof
to properly detectConstruct
instances, even when the construct library is symlinked.Explanation: in JavaScript, multiple copies of the
constructs
library on disk are seen as independent, completely different libraries. As a consequence, the classConstruct
in each copy of theconstructs
library is seen as a different class, and an instance of one class will not test asinstanceof
the other class.npm install
will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of theconstructs
library can be accidentally installed, andinstanceof
will behave unpredictably. It is safest to avoid usinginstanceof
, and using this type-testing method instead.- Parameters:
x (
Any
) – Any object.- Return type:
bool
- Returns:
true if
x
is an object created from a class which extendsConstruct
.
