Using the following code, I can get the memory consumption of a give process in MiB: def memory_usage_psutil(): # return the memory usage in MB import psutil process = psutil.Process(os.getpid()) mem = process.get_memory_info()[0] / float(2 ** 20) return mem How can I change this to return the percentage of memory consumption? Update : I need to get the current value of %MEM column when executing the top command in terminal for a specific process. Example : I need this function to return 14.2 for the process id of VirtualBox process. use process.memory_percent() This agrees with top. In the

My original script is cpu.py. The dir contains a lot of ".so" files and 1 "cpu" file. 2) When I try "cpu" from the list above, I get this output. 'psutil' is a Python module required for the script - cpu.py. Desktop/build/exe.macosx-10.8-x86_64-2.7/cpu ; exit; Traceback (most recent call last): File

要使用Python获取计算机的内存信息需要用到psutil模块，能够获得的内存信息有内存总量、可用内存总量、已用内存量、内存使用百分比等信息。 写一个简单的小脚本，代码如下： #!/usr/bin/python import psutil pc_mem =psutil.virtual_memory() div_gb_factor =(1024.0 ** 3) print("totalmemor: %fGB" % float(pc_mem.total/div_gb_factor)) print("availablememory: %fGB" % float(pc_mem.available/div_gb_factor)) print("usedmemory: %GB" % float(pc_mem.used/div_gb_factor)) print("percentof used memory: %f" % float(pc_mem.percent)) print("freememory:%fGB" % float(pc_mem.free/div_gb_factor)) 程序运行结果如下; In [1]: %runos_mem.py total memor:15.868237GB available memory:13.069672GB used memory:2.79856B

一、psutil模块 1. psutil是一个跨平台库（ http://code.google.com/p/psutil/ ），能够轻松实现获取系统运行的进程和系统利用率（包括CPU、内存、磁盘、网络等）信息。它主要应用于系统监控，分析和限制系统资源及进程的管理。它实现了同等命令行工具提供的功能，如ps、top、lsof、netstat、ifconfig、who、df、kill、free、nice、ionice、iostat、iotop、uptime、pidof、tty、taskset、pmap等。目前支持32位和64位的Linux、Windows、OS X、FreeBSD和Sun Solaris等操作系统， 2.安装 wget https: / /pypi.python.org/packages / source /p /psutil/psutil - 2.0 . 0 .tar.gz tar -xzvf psutil- 2.0 . 0 .tar.gz cd psutil- 2.0 . 0 python setup.py install 3.使用 获取系统性能信息（CPU,内存，磁盘，网络） 3.1CPU相关 查看cpu信息 import Psutil 查看cpu所有信息 >>> psutil.cpu_times() scputimes(user= 11677.09 , nice=
