如题，一台多核的机器，我用taskset命令绑定了两个进程到一个核上面，我想获得以下信息:每个进程占用的详细时间片每个进程详细的上下文切换时间每个进程的上下文切换次数vmstat可以统计整个CPU的cs次数，但是好像没有工具针对单个核做这个事情的，请问有没有类似工具或脚本?补充下:内核版本为:2.6.18-348.12.1.el5

如何在Linux下用c语言创建守护进程并监控系统运行期间的所有进程？

要求记录的信息包括：进程pid，可执行程序名称，用户名，创建时间，撤销时间。老师布置的一道作业题。自己google过了，也上数据库搜了别人的论文看，但是他们都只讲了怎么创建守护进程。给点提示就好，我再自行解决。谢谢！
