Is Lambda invocation = 0 is a guaranteed metric that proves the Lambda function was unused during the period I provide to metric?

Hey everyone,

I am doing a general cleanup on Lambda functions. As I don't want to ruin the production environment, I want to make sure that Lambda is not used at all before deleting it.

I am using Lambda monitor tab > CloudWatch metrics -> Invocation metric Can we say that when invocation count is 0 the Lambda is not used at all for the time interval I provide?

Thank you all in advance for your time and help!

Invocations counts the number of times the function was invoked. So yes, if it 0, it means it was not invoked. I do recommend that you use the Sum option in the dashboard to make sure you do not miss some small numbers.

I will check out the Sum option, thank you Uri.
