cloudtrail (读取 Records 字段)

Cloudtrail Transformer 是针对 AWS CloudTrail 的数据做格式转换的 Transformer，可以将 CloudTrail 的 json 格式中的 Records逐条变为数据。

示例：

将数据由一条：

{"Records": [{
    "eventVersion": "1.04",
    "userIdentity": {
        "type": "IAMUser",
        "principalId": "EX_PRINCIPAL_ID",
        "arn": "arn:aws:iam::123456789012:user/Alice",
        "accountId": "123456789012",
        "accessKeyId": "EXAMPLE_KEY_ID",
        "userName": "Alice"
    },
    "eventTime": "2016-07-14T19:15:45Z",
    "eventSource": "cloudtrail.amazonaws.com",
    "eventName": "UpdateTrail",
    "awsRegion": "us-east-2",
    "sourceIPAddress": "205.251.233.182",
    "userAgent": "aws-cli/1.10.32 Python/2.7.9 Windows/7 botocore/1.4.22",
    "errorCode": "TrailNotFoundException",
    "errorMessage": "Unknown trail: myTrail2 for the user: 123456789012",
    "requestParameters": {"name": "myTrail2"},
    "responseElements": null,
    "requestID": "5d40662a-49f7-11e6-97e4-d9cb6ff7d6a3",
    "eventID": "b7d4398e-b2f0-4faa-9c76-e2d316a8d67f",
    "eventType": "AwsApiCall",
    "recipientAccountId": "123456789012"
},{
    "eventVersion": "1.0",
    "userIdentity": {
        "type": "IAMUser",
        "principalId": "EX_PRINCIPAL_ID",
        "arn": "arn:aws:iam::123456789012:user/Alice",
        "accountId": "123456789012",
        "accessKeyId": "EXAMPLE_KEY_ID",
        "userName": "Alice"
    },
    "eventTime": "2014-03-24T21:11:59Z",
    "eventSource": "iam.amazonaws.com",
    "eventName": "CreateUser",
    "awsRegion": "us-east-2",
    "sourceIPAddress": "127.0.0.1",
    "userAgent": "aws-cli/1.3.2 Python/2.7.5 Windows/7",
    "requestParameters": {"userName": "Bob"},
    "responseElements": {"user": {
        "createDate": "Mar 24, 2014 9:11:59 PM",
        "userName": "Bob",
        "arn": "arn:aws:iam::123456789012:user/Bob",
        "path": "/",
        "userId": "EXAMPLEUSERID"
    }}
}]}

转变为两条：

{
    "eventVersion": "1.04",
    "userIdentity": {
        "type": "IAMUser",
        "principalId": "EX_PRINCIPAL_ID",
        "arn": "arn:aws:iam::123456789012:user/Alice",
        "accountId": "123456789012",
        "accessKeyId": "EXAMPLE_KEY_ID",
        "userName": "Alice"
    },
    "eventTime": "2016-07-14T19:15:45Z",
    "eventSource": "cloudtrail.amazonaws.com",
    "eventName": "UpdateTrail",
    "awsRegion": "us-east-2",
    "sourceIPAddress": "205.251.233.182",
    "userAgent": "aws-cli/1.10.32 Python/2.7.9 Windows/7 botocore/1.4.22",
    "errorCode": "TrailNotFoundException",
    "errorMessage": "Unknown trail: myTrail2 for the user: 123456789012",
    "requestParameters": {"name": "myTrail2"},
    "responseElements": null,
    "requestID": "5d40662a-49f7-11e6-97e4-d9cb6ff7d6a3",
    "eventID": "b7d4398e-b2f0-4faa-9c76-e2d316a8d67f",
    "eventType": "AwsApiCall",
    "recipientAccountId": "123456789012"
}

{
    "eventVersion": "1.0",
    "userIdentity": {
        "type": "IAMUser",
        "principalId": "EX_PRINCIPAL_ID",
        "arn": "arn:aws:iam::123456789012:user/Alice",
        "accountId": "123456789012",
        "accessKeyId": "EXAMPLE_KEY_ID",
        "userName": "Alice"
    },
    "eventTime": "2014-03-24T21:11:59Z",
    "eventSource": "iam.amazonaws.com",
    "eventName": "CreateUser",
    "awsRegion": "us-east-2",
    "sourceIPAddress": "127.0.0.1",

        "userName": "Bob",
        "arn": "arn:aws:iam::123456789012:user/Bob",
        "path": "/",
        "userId": "EXAMPLEUSERID"
    }}
}
