但是，如果直接查看源码，源码可能代码量大，且分支多，不容易理清。就需要让相关程序运行起来查看。2.查看某个函数被执行时的routine。1.查看某个场景下的代码执行流。1.无侵入方式（不修改源码）2.侵入方式（修改源码）

linux tc ebpf 示例

I’ve been confused about Linux tracing systems foryears. There’s strace, and ltrace, kprobes, and tracepoints, and uprobes, and ftrace, and perf, and eBPF,and how does it all fit together and what does it all MEAN?Last week I went to Papers We Love and.
