The oldest (but also the most effective) way of understanding a system is to check the logs to see if they contain something that is printed in case of a problem. Structured logging is particularly helpful if you want to troubleshoot as quickly as possible. However, checking for logs isn’t a straightforward process on CloudWatch, and you only have the capability to check the logs of one function at once. The Logs page solves this problem by giving you the flexibility to search the logs of all your serverless stacks.
