运行 hidumper --mem [pid] 命令获取全部的内存使用信息。如果指定进程的pid，只获取该进程的内存使用情况。

hidumper --mem [pid]

[md]这是hidumper的help，有两个看内存的方式，简单看也可以看top -p pid，但是其实也有可能是别的方式占用内存，cat /proc/pid/status，都行

# hidumper -help

usage:
-h                         |help text for the tool
-lc                      |a list of system information clusters
-ls                      |a list of system abilities
-c                         |all system information clusters
-c [base system]          |system information clusters labeled "base" and "system"
-s                         |all system abilities
-s [SA0 SA1]             |system abilities labeled "SA0" and "SA1"
-s [SA] -a ['-h']          |system ability labeled "SA" with arguments "-h" specified
-e                         |faultlogs of crash history
--net                      |dump network information
--storage                |dump storage information
-p                         |processes information, include list and infromation of processes and threads
-p [pid]                   |dump threads under pid, includes smap, block channel, execute time, mountinfo
--cpuusage [pid]          |dump cpu usage by processes and category; if PID is specified, dump category usage of specified pid
--cpufreq                |dump real CPU frequency of each core
--mem [pid]                |dump memory usage of total; dump memory usage of specified pid if pid was specified
--zip                      |compress output to /data/log/hidumper
--mem-smaps pid [-v]       |display statistic in /proc/pid/smaps, use -v specify more details
