Can't reproduce that high amount of data charged in my aws bill for cloudwatch

Question

Hello,
in my last bill of aws there were more thn 9GB "ingested data" for the cloudwatch service (i know 5GB are in free tier, but anyway over 4GB left)
I can't understand where this high data-usage comes from and i cannot reproduce it via the metrics. If i check the ingested data according to this tutorial (https://repost.aws/knowledge-center/cloudwatch-logs-bill-increase) i get in sum less than 1GB

How could i reproduce that and who should i contact?

Answer

Hello.

It is possible that CloudWatch Logs could exceed 9 GB after a month of use.  
For example, if RDS extended monitoring is enabled, logs are output to CloudWatch Logs.  
Is it possible to share an image of the invoice for possible other causes?
