AWS Cloud Trail日志解析

我想从Cloud Trail日志解析嵌套的JSON以获取用户名数据和时间我该怎么做呢是否有我可以在Lambda中使用的代码或者有一些工具，例如JSON文件看起来像这样AWS Cloud Trail日志解析

{"version":"0","id":"5bd0a964-0969-4b1a-badd-3b4f7e9e077f","detail-type":"AWS API Call via CloudTrail","source":"aws.ec2","account":"111111111","time":"2017-04-25T16:07:33Z","region":"us-west-2","resources":[],"detail":{"eventVersion":"1.05","userIdentity":{"type":"Root","principalId":"1111111","arn":"arn:aws:iam::137247507067:root","accountId":"111111111","accessKeyId":"AAAAAAAA","userName":"roger","sessionContext":{"attributes":{"mfaAuthenticated":"true","creationDate":"2017-04-25T05:44:56Z"}}},"eventTime":"2017-04-25T16:07:33Z","eventSource":"ec2.amazonaws.com","eventName":"ModifyImageAttribute","awsRegion":"us-west-2","sourceIPAddress":"X.X.X.X","userAgent":"console.ec2.amazonaws.com","requestParameters":{"imageId":"ami-36e85556","launchPermission":{"add":{"items":[{"userId":"879125893843"}]}},"attributeType":"launchPermission"},"responseElements":{"_return":true},"requestID":"06ae4745-2d29-4a3b-b526-c5d8c4b4a7fc","eventID":"fc57b805-ae30-4ec7-bf4f-7a9c971ae0c7","eventType":"AwsApiCall"}}

您可以使用AWS Athena。

它基本上将云轨日志加载到表中，所以我们可以很容易地查询所有的东西。

它有更多的选择来分析cloudtrail logs.For例如，如果你想知道是谁发动的EC2实例，然后查询这个样子，

SELECT date_format(from_iso8601_timestamp(eventTime), '%Y-%m-%d') AS EventDate,useridentity.arn UserARN, 
     awsregion AS Region, 
     json_extract_scalar(item,'$.instanceId') AS InstanceId 
FROM cloudtrail_logs 
CROSS JOIN UNNEST (cast(json_extract(responseElements,'$.instancesSet.items') AS array(json))) AS i (item) 
WHERE eventsource='ec2.amazonaws.com' 
    AND eventname = 'RunInstances' 
    AND eventtime >= '2017-04-25T02:00:00.000' 
order by eventtime desc limit 2;

结果是，
