pmap命令查看进程用了多少内存

pmap命令   查看进程用了多少内存
用法
       pmap [ -x | -d ] [ -q ] pids
       pmap -V
选项含义
       -x   extended       Show the extended format. 显示扩展格式
       -d   device         Show the device format.   显示设备格式
       -q   quiet          Do not display some header/footer lines. 不显示头尾行
       -V   show version   Displays version of program. 显示版本

扩展格式和设备格式域：
        Address: start address of map 映像起始地址
        Kbytes: size of map in kilobytes 映像大小
        RSS: resident set size in kilobytes 驻留集大小
        Dirty: dirty pages (both shared and private) in kilobytes 脏页大小
        Mode: permissions on map 映像权限: r=read, w=write, x=execute, s=shared, p=private (copy on write)

Mapping: file backing the map , or ‘[ anon ]’ for allocated memory, or
‘[ stack ]’ for the program stack. 映像支持文件,[anon]为已分配内存 [stack]为程序堆栈
        Offset: offset into the file 文件偏移
        Device: device name (major:minor) 设备名

应用示例：

[root@GameServer- ~]# pmap -d
:   /usr/local/src/percona-5.6./bin/mysqld --defaults-file=/data/perconadata_3307/my.cnf --basedir=/usr/local/src/percona-5.6. --datadir=/data/perconadata_3307 --plugin-dir=/usr/local/src/percona-5.6./lib/mysql/plugin --user=mysql --log-error=/data/perconadata_3307/mysql-error.log --open-files-limit= --pid-file=/data/perconadata_3307/mysql.pid --socket=/data/perconadata_3307/mysql.sock --port=
