跟踪pthread调度 [英] Tracing pthread scheduling

问题描述

我想做的是创建某种图形，详细描述Linux中(两个)线程的执行情况.我不需要看线程在做什么，只需要安排它们的时间，基本上就可以看到一个时间表.

What I want to do is create some kind of graph detailing the execution of (two) threads in Linux. I don't need to see what the threads do, just when they are scheduled and for how long, a time line basically.

我花了最后几个小时在互联网上搜索一种跟踪pthread调度的方法.不幸的是，我发现的两个项目都需要重新编译内核( LTTng )或glibc修补

I've spend the last few hours searching the internet for a way to trace the scheduling of pthreads. Unfortunately, the two projects I found require either kernel recompilation (LTTng) or glibc patching (NPTL Trace Tool), both of which I can not do (large, centrally managed system, on which I have no sudo rights).

还有其他方法可以做这样的事情吗?还是我不得不求助于我可以在其上进行补丁/重新编译的笔记本电脑?

Is there any other way to do something like this or will I have to resort to finding a laptop on which I can patch/recompile whatever I want?

最诚挚的问候

PS:我本来可以链接到这两个项目，但该网站不允许我这样做(声誉＜10).不过，在Google上第一个搜索到的项目名称是正确的搜索结果.

PS: I would have linked to both projects, but the site doesn't allow me (reputation < 10). The first search result on Google for the project names is the correct one though.

推荐答案

构建检测的glibc/libpthread.so不需要超级用户特权. ptt_trace 程序，它是

Superuser privileges are not needed to build an instrumented glibc / libpthread.so. The ptt_trace program that is part of NPTL Trace Tool will run your program using the instrumented library.
