Python--内存分析工具汇总

gdb

• 下载libpython.py文件到服务器目录，比如：/root/utils/libpython.py
• 进入gdb命令，加载好libpython

(gdb) python
>import sys
>sys.path.insert(0,"/root/utils")
>import libpython
>end
(gdb) py
py-bt               py-down             py-locals           py-up               python-interactive
py-bt-full          py-list             py-print            python        

• 这样就可以使用py-xx命令查看python进程数据了

tracemalloc

• python官方自带的内存分析工具
• https://docs.python.org/zh-cn/3.11/library/tracemalloc.html#module-tracemalloc

pyrasite

• pyrasite可往python进程注入脚本，不过很容易把目标进程搞挂了
• pyrasite-shell可以进入python进程，然后打印程序中全局变量等信息

objgraph

• 可以把引用关系生成.dot文件，然后用pygraphviz进行可视化

objgraph.show_backrefs(objgraph.by_type('类型名称')[0], max_depth = 10, filename = '文件名称.dot')

pygraphviz

• 可以用来可视化.dot文件

import pygraphviz as pgv
G = pgv.AGraph("文件名称.dot")  
G.draw("文件名称.svg", prog="dot")
