Lambdas (via AWS CloudWatch)

1 min

Using CloudWatch you can correlate and view metrics on any AWS service. For Lambdas, it is particularly useful to check for example the number of invocations of different functions in order to know which are more often called, how much, duration, etc.

An example of this above scenario can be seen in the following link:
