# 记录集成服务的 API 调用
您可以使用审核 CloudTrail 与 ACM 集成的服务发出的 API 调用。有关使用的更多信息 CloudTrail，请参阅《[Amazon CloudTrail 用户指南》](https://docs.amazonaws.cn/awscloudtrail/latest/userguide/cloudtrail-user-guide.html)。以下示例显示了可生成的日志的类型，具体取决于您用于预置 ACM 证书的 Amazon 资源。

## 创建负载均衡器
您可以使用审核 CloudTrail 与 ACM 集成的服务发出的 API 调用。有关使用的更多信息 CloudTrail，请参阅《[Amazon CloudTrail 用户指南》](https://docs.amazonaws.cn/awscloudtrail/latest/userguide/cloudtrail-user-guide.html)。以下示例显示了可以生成的日志类型，具体取决于您配置 ACM 证书所依据的 Amazon 资源。

### 创建负载均衡器
以下示例演示名为 Alice 的 IAM 用户对 `CreateLoadBalancer` 函数的调用。负载均衡器的名称是 `TestLinuxDefault`，而且侦听器是使用 ACM 证书创建的。
```

}
```
### 使用负载均衡器注册 Amazon EC2 实例
当您在某个 Amazon Elastic Compute Cloud (Amazon EC2) 实例上预置网站或应用程序时，负载均衡器必须了解该实例。这可以通过 Elastic Load Balancing 控制台或 Amazon Command Line Interface来完成。以下示例显示了对 Amazon 账户 123456789012 LinuxTest 上名`RegisterInstancesWithLoadBalancer`为的负载均衡器的调用。
```
{
"eventVersion":"1.03",
"userIdentity":{
"type":"IAMUser",

}
```
### 加密私有密钥
以下示例说明用于加密与 ACM 证书关联的私有密钥的 `Encrypt` 调用。加密是在 Amazon中执行。
```

### 解密私有密钥
以下示例显示了用于对与 ACM 证书关联的私有密钥进行解密的 `Decrypt` 调用。解密是在内部执行的 Amazon，解密后的密钥永远不会离开。 Amazon
```
