Python psutil module simple use example

This article mainly introduces the Python psutil module's simple examples. This article provides a script to view cpu information, memory information, system startup time, and network card information, for more information, see

Easy to install

The Code is as follows:

Pip install psutil

Psutil is better. One is cross-platform, and it is re-opened when you do not need to switch the platform. Another good tool is CPU, memory, disks, network, this information can be obtained.

It can be used for system monitoring, performance analysis, and process management. Supported systems include Linux, Windows, OSX, FreeBSD and Sun Solaris, 32, and 64-bit systems, and pyhton2.4 to 3.4.

In order to see whether cross-platform services are useful

The Code is as follows:

Follow the tutorial to learn how to use psutil. Try it in windows.

'''

Import psutil

Import datetime

# View cpu Information

Print u "CPU count % s" % psutil. cpu_count ()

Print u "physical CPU count % s" % psutil. cpu_count (logical = False)

Print u "CPU uptimes"

Print psutil. cpu_times ()

Print ""

# View memory information

Print u "total system memory % s M" % (psutil. TOTAL_PHYMEM/1024/1024)

Print u "available system 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)

# System startup time

Print u "system start time % s" % datetime. datetime. fromtimestamp (psutil. boot_time ()). strftime ("% Y-% m-% d % H: % M: % S ")

# System users

Users_count = len (psutil. users ())

Users_list = ",". join ([u. name for u in psutil. users ()])

Print u "currently has % s users, respectively % s" % (users_count, users_list)

# Nic. You can obtain Nic attributes, 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 "Nic received traffic % s Nic sent traffic % s" % (bytes_rcvd, bytes_sent)

# Detailed parameters of a process

# Disk usage and so on

In this simple case, we can see that the power of PstI is so powerful in Windows that it is very suitable for system data collection.
