CPU Monitor With Python And WMI
CPU Monitor With Python And WMI
Submitted by Corey Goldberg on Mon, 13/11/2006 - 02:10.Tim Golden's WMI module for Python
is a lightweight wrapper around the WMI
classes available for all Win32 platforms.
Windows Management Instrumentation (WMI) is Microsoft's implementation of Web-Based Enterprise Management (WBEM), an industry initiative to provide a Common Information Model (CIM) for pretty much any information about a computer system.
I will give a simple example of monitoring your local CPU using the WMI module from a Python program.
First, we can explore the WMI Win32_Processor class:
Output looks like this:
Here I use it in a script that prints CPU utilization every 5 seconds:
Output looks like this:

First, we can explore the WMI Win32_Processor class:
import wmi
c = wmi.WMI()
for s in c.Win32_Processor():
print s
Output looks like this:
instance of Win32_Processor
{
AddressWidth = 32;
Architecture = 0;
Availability = 3;
Caption = "x86 Family 6 Model 13 Stepping 6";
CpuStatus = 1;
CreationClassName = "Win32_Processor";
CurrentClockSpeed = 1794;
CurrentVoltage = 33;
DataWidth = 32;
Description = "x86 Family 6 Model 13 Stepping 6";
DeviceID = "CPU0";
ExtClock = 133;
Family = 2;
L2CacheSize = 2048;
Level = 6;
LoadPercentage = 6;
Manufacturer = "GenuineIntel";
MaxClockSpeed = 1794;
Name = " Intel(R) Pentium(R)
M processor 1.80GHz";
PowerManagementSupported = FALSE;
ProcessorId = "AFE9F9BF000006D6";
ProcessorType = 3;
Revision = 3334;
Role = "CPU";
SocketDesignation = "Microprocessor";
Status = "OK";
StatusInfo = 3;
Stepping = "6";
SystemCreationClassName = "Win32_ComputerSystem";
SystemName = "GOLDB";
UpgradeMethod = 6;
Version = "Model 13, Stepping 6";
VoltageCaps = 2;
};
Here I use it in a script that prints CPU utilization every 5 seconds:
import wmi
import time
c = wmi.WMI()
while True:
for cpu in c.Win32_Processor():
timestamp = time.strftime('%a, %d %b %Y
%H:%M:%S', time.localtime())
print '%s | Utilization: %s: %d %%' % (timestamp,
cpu.DeviceID, cpu.LoadPercentage)
time.sleep(5)
Output looks like this:
Sun, 12 Nov 2006 19:26:25 | Utilization: CPU0: 4 %
Sun, 12 Nov 2006 19:26:31 | Utilization: CPU0: 8 %
Sun, 12 Nov 2006 19:26:37 | Utilization: CPU0: 1 %
Sun, 12 Nov 2006 19:26:43 | Utilization: CPU0: 6 %
Sun, 12 Nov 2006 19:26:49 | Utilization: CPU0: 13 %
