如何获取调用的AWS lambda任务的性能统计信息？

Question

I am submitting tasks (eventually this will be hundreds of thousands of tasks) to AWS lambda using InvokeRequest class , and I am interested in performance characteristics of the task: execution time, memory usage, etc.

Note that I will eventually want to compute various performance statistics and plots of the submitted tasks in costum code.

Answer 1

You can get execution time (Duration), Error count, Invocation count and Throttles metrics in CloudWatch. For memory usage I think you would have to pull that from CloudWatch Logs somehow. You might start by looking at this AWS forum thread which discusses AWS Lambda memory profiling.
