检查哪个线程在linux中的哪个CPU上运行 [英] Check which thread is running on which CPU in linux

问题描述

我有兴趣查找哪个线程在哪个内核/CPU上运行.我的Tomcat6正在使用100％的单个CPU内核，而所有其他CPU(我的服务器还有16个其他空闲内核)都没有被利用...所以我试图找出出了什么问题.

I'm interested in finding which thread is running on which core/CPU. My Tomcat6 is using a single CPU core 100% and all other CPUs (my server has 16 other cores idle) are not being utilized... so I'm trying to figure out what went wrong.

推荐答案

有趣的是，人们对此表示不满，但不知道原因.我搜索了一会儿，发现以下命令给出了哪个线程在哪个CPU上运行:

Funny that people downvotes but don't tell why. I searched for a while and found that following command gives which thread running on which CPU:

ps -p <PID> -L -o pid,tid,psr

其中< PID>是我们感兴趣的过程的pid.

Where < PID > is the pid of the process we are interested in.
