psutil 4.0.0 的新特性介绍

1. 新增了进程内存真正使用信息

   psutil.Process().memory_full_info()

2. 新增了进程环境变量功能

   >>> import psutil
   >>> from pprint import pprint as pp
   >>> pp(psutil.Process().environ())
   {...
    'CLUTTER_IM_MODULE': 'xim',
    'COLORTERM': 'gnome-terminal',
    'COMPIZ_BIN_PATH': '/usr/bin/',
    'HOME': '/home/giampaolo',
    'PWD': '/home/giampaolo/svn/psutil',
   }
   >>>

3. 扩展了 disk IO 状态

   • busy_time, which is the time spent doing actual I/Os (in milliseconds).

   • read_merged_count and write_merged_count (Linux only), which is number of merged reads and writes (see iostats doc)
