Python Psutil for System Management

• First you need to install the Psutil package

  1   wget https://pypi.python.org/packages/source/p/psutil/psutil-2.0.0.tar.gz-- No-check-certificate2   tar -zxvf psutil-2.0.  0. Tar . GZ 3   CD psutil-2.0. 0 4   Install

The installation is complete, and the Python version here is 3.4

• Reference Psutil

  1 Import Psutil

• CPU utilization

The CPU utilization of the Linux operating system has the following parts:

User Time，执行用户进程的时间百分比；* System Time，执行内核进程和中断的时间百分比；* Wait IO，由于 IO 等待而使 CPU 处于 idle（空闲）状态的时间百分比；* Idle，CPU 处于 idle 状态的时间百分比

1 Import Psutil 2 psutil.cpu_times ()  # Use the Cpu_times method to get full CPU information, need to display all the logical CPU information, specify the method variable percpu=true, such as Psutil.cpu_time S (percpu=True)3psutil.cpu_times (). User # Gets individual data information, such as the user's CPU time compared to 4 psutil.cpu_ Count () # Gets the logical number of CPUs, default logical=True45 psutil.cpu_count (logical=false) # Gets the physical number of CPUs

• Memory parameter

   1  mem = Psutil.virtual_ Memory () # Use the Psutil.virtual_memory method to get the full information of the Ram  2   Mem.total # gets total memory  3  mem. free   # Get free memory number  4  psutil.swap_memory () # Get swap partition information 

   

• Disk information

  1   psutil.disk_partitions () # Get disk full information using the Psutil.disk_partitions method 2   psutil.disk_usage (  '/') # Use the Psutil.disk_usage method to get the partition (parameter) usage 3  Psutil.disk_io_ Counters () # Use Psutil.disk_io_counters to get the total IO number of the drive 4   psutil.disk_io_counters (perdisk=true) # " Perdisk=true "parameter gets the number of single partition IO

* Network Information

1     Psutil.net_io_counters () # Use Psutil.net_io_counters to get the total IO information of the network, default pernic=False2     psutil.net_ Io_counters (pernic=true) #pernic =true output IO information for each network interface

• Other System Information

  1 psutil.users () # Use the Psutil.users method to return user information for the currently logged on system
