# Canary に必要なロールとアクセス許可
<a name="CloudWatch_Synthetics_Canaries_CanaryPermissions"></a>

各 Canary は、特定の許可がアタッチされた IAM ロールに関連付ける必要があります。CloudWatch コンソールを使用して Canary を作成する場合、CloudWatch Synthetics で Canary の IAM ロールを作成することを選択できます。これを実行すると、ロールに必要な許可が付与されます。

自ら IAM ロールを作成する場合、または AWS CLI もしくは API を使用して Canary を作成するときに使用できる IAM ロールを作成する場合、そのロールにはこのセクションにリストされている許可が含まれている必要があります。

Canary のすべての IAM ロールには、次の信頼ポリシーステートメントを含める必要があります。

------
#### [ JSON ]

****  

```
{
    "Version":"2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "lambda.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}
```

さらに、Canary の IAM ロールには、次のいずれかのステートメントが必要です。
