[`stack` online tutorial](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=en&id=command-stack)

::: tip
Print out the full call stack of the current method.
:::

Most often we know one method gets called, but we have no idea on which code path gets executed or when the method gets called since there are so many code paths to the target method. The command `stack` comes to rescue in this difficult situation.
