This article mainly introduces the Python psutil module Simple Use example, this article directly gives the use script, realizes the view CPU information, the view memory information, the view system start time, the view card information and so on, needs the friend to be possible to refer to under

Installation is simple

The code is as follows:

Pip Install Psutil

The official website address is: a detailed API on the document)

GitHub address is:

Psutil is a better place, one is cross-platform, do not need to switch platform when reopened, another benefit of the Toolset CPU, memory, disks, network, this information can be obtained.

Can be used to do system monitoring, performance analysis, process management. The systems that can be supported are Linux, Windows, OS X, FreeBSD and Sun solaris,32 and 64-bit systems, supported by pyhton2.4 to 3.4.

In order to see the cross-platform good and bad, in Windows experiment

The code is as follows:

#psutiltest. py


Follow the tutorial to learn the use of Psutil, windows to try


Import Psutil

Import datetime


Print U "CPU number%s"%psutil.cpu_count ()

Print U "number of physical CPUs%s"%psutil.cpu_count (Logical=false)

Print U "CPU uptimes"

Print Psutil.cpu_times ()

Print ""


Print U "System total memory%s M"% (psutil. total_phymem/1024/1024)

Print U "System free memory%s M"% (Psutil.avail_phymem ()/1024/1024)

mem_rate = Int (Psutil.avail_phymem ())/float (Psutil. TOTAL_PHYMEM)

Print U "system memory usage%s%"%int (mem_rate*100)


Print U "System boot time%s"%datetime.datetime.fromtimestamp (Psutil.boot_time ()). Strftime ("%y-%m-%d%h:%m:%s")


Users_count = Len (Psutil.users ())

Users_list = ",". Join ([ for U in Psutil.users ()])

Print U "currently has%s users,%s"% (Users_count, users_list)

#网卡, you can get the network card properties, the number of connections, current traffic and other information

NET = Psutil.net_io_counters ()

Bytes_sent = ' {0:.2f} KB '. Format (net.bytes_recv/1024)

Bytes_rcvd = ' {0:.2f} KB '. Format (net.bytes_sent/1024)

Print U "network card receive traffic%s NIC send traffic%s"% (BYTES_RCVD, bytes_sent)

#进程 the various detailed parameters of a process

#磁盘 The amount of disk usage, and so on

From this simple case can be seen Psuti strong, in the window also so good, do system data acquisition is very appropriate.

Please refer to the official documentation in detail if you need to use it.
