Linux— 进程跟踪手段

Linux— 进程跟踪手段

strace方法:
strace XXX -o ttt  — 跟踪XXX执行过程调用的系统调用,结果保存到ttt文件

strace -c XXX — 跟踪XXX每次调用系统调用耗费时长

strace -f XXX — 跟踪XXX所有进程包括子进程的系统调用

strace -e trace=open,write XXX  —跟踪XXX执行过程调用的open、write系统调用

strace -e trace=network -p 24567  —跟24567进程所有与网络有关的系统调用

ltrace方法:
ltrace –s XXX  — 跟踪系统调用和库函数调用

ltrace –e strcpy,strlen XXX — 跟踪进程调用的strcpy、strlen两种库函数

ltrace -l /lib64/librt.so.1 XXX — 跟踪XXX调用的指定动态库中的库函数

valgrind方法:
默认没有安装,必须手工安装该工具。

valgrind –tool=memcheck –trace-children=yes XXX

— 使用valgrind的memcheck工具对XXX命令执行内存检测。

memcheck

Detects memory errors. It helps you tune your programs to behave correctly.

cachegrind

Profiles cache prediction. It helps you tune your programs to run faster.

callgrind

Works in a similar way to cachegrind but also gathers additional cache-profiling information.

exp-drd

Detects thread errors. It helps you tune your multi-threaded programs to behave correctly.

helgrind

Another thread error detector. Similar to exp-drd but uses different techniques for problem analysis.

massif

A heap profiler. Heap is an area of memory used for dynamic memory allocation.This tool helps you tune your program to use less memory.

lackey

An example tool showing instrumentation basics
