# AWS::ObservabilityAdmin::OrganizationCentralizationRule LogGroupNameConfiguration
<a name="aws-properties-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration"></a>

Configuration that specifies a naming pattern for destination log groups created during centralization. The pattern supports static text and dynamic variables that are replaced with source attributes when log groups are created.

## Syntax
<a name="aws-properties-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration-syntax.json"></a>

```
{
  "[LogGroupNamePattern](#cfn-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration-loggroupnamepattern)" : String
}
```

### YAML
<a name="aws-properties-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration-syntax.yaml"></a>

```
  [LogGroupNamePattern](#cfn-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration-loggroupnamepattern): String
```

## Properties
<a name="aws-properties-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration-properties"></a>

`LogGroupNamePattern`  <a name="cfn-observabilityadmin-organizationcentralizationrule-loggroupnameconfiguration-loggroupnamepattern"></a>
The pattern used to generate destination log group names during centralization. The pattern can contain static text and dynamic variables that are replaced with source attributes. If a variable cannot be resolved, it inherits the value from its parent variable in the hierarchy. The pattern must be between 1 and 512 characters.  
Supported variables:  
+ **\$1\$1source.logGroup\$1** — The original log group name from the source account.
+ **\$1\$1source.accountId\$1** — The AWS account ID where the log originated.
+ **\$1\$1source.region\$1** — The AWS Region where the log originated.
+ **\$1\$1source.org.id\$1** — The AWS Organization ID of the source account.
+ **\$1\$1source.org.ouId\$1** — The organizational unit ID of the source account.
