How to get performance stats of the invoked AWS lambda task?

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.

您可以在CloudWatch中获取执行时间（持续时间），错误计数，调用计数和Throttles指标。对于内存使用，我认为您必须以某种方式从CloudWatch Logs中获取内存。您可以先查看讨论AWS Lambda内存分析的this AWS forum thread。
