I'm trying to clean up some Lambda functions in our account. When I click on the Monitor tab for each function, everything is coming up with "No data available". I know at least one of those functions are associated with a CloudFront distribution, and I was able to pull up that function's logs via CloudFront. But I don't know where to look for any information or logs for the other functions.
Basically, I want to verify whether or not the other functions are being used/invoked at all so that I know I'm not disrupting anything if I delete them.
