本项目旨在开发一个Linux进程到各子系统的调用栈画像工具，通过该工具可以明确展示出：

  • 一个进程使用系统资源的完整的函数调用路径
  • 进程/线程阻塞的时长、阻塞原因（内存分配、主动睡眠、锁竞争等）及调用路径，从而解决出进程执行慢、甚至卡死的问题
  • 进程/线程使用cpu的计数，从而分析出进程的用时最长的调用栈即性能瓶颈
  • 进程/线程内存占用的大小及分配路径、更进一步可以检测出释放无效指针的问题，从而优化进程的内存分配方式
  • 进程/线程输入/输出的数据量或者次数，及相应路径，从而优化进程输入/输出方式
  • 进程/线程预读取页面使用量及对应调用栈，从而了解进程读数据的行为特征，进而使用madvise进行优化
  • 统计指定调用栈的调用次数，使工具更加灵活
  • 加入更多的可视化元素和交互方式，使得画像更加直观、易于理解
