获取CPU和内存的利用率Python模块 ， psutil 3.3.0 发布

psutil 是一个 Python模块用来获取正在运行的进程信息和系统的CPU和内存的利用率。类似 Linux 的 ps 、top 和 Windows 的任务管理器等程序。

psutil 3.3.0 发布，主要更新如下：

• Process.memory_maps() is not implemented. The kernel provides the necessary pieces but I didn't do this yet (hopefully later).

• Process.num_ctx_switches()'s involuntary field is always 0. kinfo_proc provides this info but it is always set to 0.

• Process.cpu_affinity() (get and set) is not supported.

• Process.exe() is determined by inspecting the command line so it may not always be available (return None). 

• psutil.swap_memory() sin and sout (swap in and swap out) values are not available and hence are always set to 0.

• psutil.cpu_count(logical=False) always return None.
