Linux - 内存分析工具pmap
pmap工具是linux的工具,能够查看进程用了多少内存,还能分析内存用在上面环节,对于一些长期占用内存居高不下的程序可以分析其行为,命令简单,信息简洁。@pdai
使用简介
[root@pdai-centos ~]# pmap -h
Usage:
pmap [options] PID [PID ...]
Options:
-x, --extended show details
-X show even more details
WARNING: format changes according to /proc/PID/smaps
-XX show everything the kernel provides
-c, --read-rc read the default rc
-C, --read-rc-from=<file> read the rc from file
-n, --create-rc create new default rc
-N, --create-rc-to=<file> create new rc to file
NOTE: pid arguments are not allowed with -n, -N
-d, --device show the device format
-q, --quiet do not display header and footer
-p, --show-path show path in the mapping
-A, --range=<low>[,<high>] limit results to the given range
-h, --help display this help and exit
-V, --version output version information and exit
For more details see pmap(1).

mapped: 1137256K writeable/private: 489808K shared: 4096K
最后一行的值
mapped表示该进程映射的虚拟地址空间大小，也就是该进程预先分配的虚拟内存大小，即ps出的vszwriteable/private表示进程所占用的私有地址空间大小，也就是该进程实际使用的内存大小shared表示进程和其他进程共享的内存大小
