您如何在资源有限的情况下衡量 spring 启动 api 的性能？

Question

Let's say we have a monolithic rest API written in Java with Spring Boot. And we want to do some performance analysis on it, how would we go about it?

The problem is measuring its performance with custom maximum usage requirements, for example, maximum ram, CPU cores, CPU clock speed, etc.

Knowing this can be useful, such as predicting cloud and other hosting fees, what is the best way of doing it?

Answer 1

Maybe you can use Spring metrics and tracing? https://spring.io/guides/tutorials/metrics-and-tracing/

Also might wanna look at Grafana k6

and Micrometer
