From the Features page of Amazon CloudWatch, it says there are three categories of logs:
- Vended logs - natively published by AWS services on behalf of the customer
- Logs published by AWS services
- Custom logs
This "natively published by AWS services on behalf of the customer" phrase is also the explanation provided in both the FAQ and news announcement. But I don't understand the difference between a Vended log and a 'normal' log published by AWS services (the 2nd category).
Can someone give me a more comprehensive explanation of Vended logs, specifically its distinction from other logs published by AWS services?
