AWS Athenaを使用できます。

基本的には、クラウドレイルのログをテーブルにロードするので、すべてのものを簡単に照会できます。

それは、あなたがEC2インスタンスを立ち上げた人を知りたい場合は、このようなクエリ、cloudtrail logs.For例を分析するためのより多くのオプションを持っている

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;
