http://googya.github.io/blog/categories/dtrace/ 最近看了点关于Dtrace的东西,它是个通用型的工具,但我主要集中于分析ruby程序的执行上面.关于操作系统的性能分析,比如cpu.内存.io.文件系统等,使用起来貌似挺复杂,木有细看. 这里简单的输出一条命令: sudo dtrace -n 'ruby$target:::object-create {@objects[copyinstr(arg0)]=count();}' -c 'ruby -e "…

与我们大多数人想象的不同,DTrace用于MySQL时不需对MySQL做任何更改.DTrace最强大的“提供器”(provider,是一组可观测的探测器)是FBT(Functional Boundary Tracing,函数边界跟踪)提供器.我们可以把它与PID提供器结合起来,用于深入观测userland过程.只需要对MySQL代码有一些基本了解,我们就可以开发挖掘这些功能了. 那么,我们如何才能了解MySQL代码呢?有两种方法.第一,你可以买一本好点儿的相关书籍,如MySQL Internal…
