> **Attention**: commands here are taking advantage of `byte code injection`, which means we are using [AOP](https://en.wikipedia.org/wiki/Aspect-oriented_programming) to monitor and analyze the classes. So when using it for online troubleshooting, you'd better *explicitly specifically* specify the classes and also remember to remove the injected code by `shutdown` or `reset` (for specific classes).
