AWS Automated DBSnapshot (System) in CloudTrail event

Question

I'm looking at triggering a lambda when a new automated DB Snapshot is available in RDS (System ones instead of Manual ones). Although after digging in CloudTrail, I don't see any events marked as follow (AWS Sample):

{
  "version": "0",
  "id": "844e2571-85d4-695f-b930-0153b71dcb42",
  "detail-type": "RDS DB Snapshot Event",
  "source": "aws.rds",
  "account": "123456789012",
  "time": "2018-10-06T12:26:13Z",
  "region": "us-east-1",
  "resources": ["arn:aws:rds:us-east-1:123456789012:db:mysql-instance-2018-10-06-12-24"],
  "detail": {
    "EventCategories": ["creation"],
    "SourceType": "SNAPSHOT",
    "SourceArn": "arn:aws:rds:us-east-1:123456789012:db:mysql-instance-2018-10-06-12-24",
    "Date": "2018-10-06T12:26:13.882Z",
    "SourceIdentifier": "rds:mysql-instance-2018-10-06-12-24",
    "Message": "Automated snapshot created"
  }
}

Thanks again if you know which AWS Events I should lookup for :)

Cloudtrail won't give you such information. I would go with the flow highlighted bellow

RDS (event notification) -> SNS -> Lambda

You need to have an SNS topic as source of your lambda, because RDS fans out its events to this service

Check what RDS document states

Amazon RDS uses the Amazon Simple Notification Service (Amazon SNS) to provide notification when an Amazon RDS event occurs

Regarding the notification itself, I could see that the DB snapshot event event bellow might be the one that you're looking for

Category	RDS event ID	Description
creation	RDS-EVENT-0091	An automated DB snapshot is being created.

Aaah that makes a lot more sense now, thank you Victor, that was the right information I was looking for :) — Oli at cdcloudlogix.com, Sep 14 '21 at 13:33
