WMI CPU Load Sensor incorrectly recognizes the number of CPU processors.



WMI CPU Load sensor incorrectly recognizes the number of CPU processors.

I have added a device which has 2 CPUs and tried to monitor the CPU Load with WMI. The device has a total of 2 CPUs and each CPU has 6 cores, so the total number of processors is 12.

However, the WMI CPU Load sensor shows only 6 processors.

Can the sensor only query a single CPU with WMI?

How can I monitor dual CPUs ?

The WMI CPU Load Sensor is using the following query:

SELECT Name,Timestamp_Sys100NS, PercentProcessorTime
FROM Win32_PerfRawData_PerfOS_Processor
WHERE Name <> '_Total'

You can use our WMI Tester to test this query manually. Alternatively you can try using the SNMP CPU Load Sensor.
