[Python monitoring] simple use of the psutil Module
Easy to install 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

In windows, try '''import psutilimport 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 "system available 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 start time print u "system start time % s" % datetime. datetime. fromtimestamp (psutil. boot_time ()). strftime ("% Y-% m-% d % H: % M: % S") # system user users_count = len (psutil. users () users_list = ",". join ([u. name for u in psutil. users ()]) print u "there are currently % s users, respectively % s" % (users_count, users_list) # Nic, you can get 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 Receiving Traffic % s Nic sending traffic % s" % (bytes_rcvd, bytes_sent) # detailed parameters of process processes # disk usage, etc.

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.
