On IBM AIX, the cpuUtilisation is calculated as the difference between the total user and system ticks from the previous sample, as a percentage of the total CPU ticks spent in /user/system/idle/wait states. The total number of CPU ticks are collected using a performance API, which is the perfstat_cpu_total function. Even if you make the sampling time the same, it is still possible that there is a minimal difference in values due to a few milliseconds difference in sampling time. It is possible that the CPU value has changed when the second sampler took a sample. Where the host has multiple CPUs, the value shown is the average utilisation of all CPUs.ĬpuUtilisation is configured, you may see a different value in two different samplers. To view the device specifications, open the Control Panel > System and Security > System.Ī moving average of the previous five samples of CPU utilisation, unless cpuSmoothing is set to false, see cpuSmoothing. On Windows, the CPU speed is displayed in the Processor field under the Device specifications. On Linux, the value is obtained with the following command: # lscpu | grep "MHz"
It displays the maximum speed frequency of the first CPU found by Netprobe. On Windows, the value is obtained with the following command: WMIC CPU Get DeviceID,NumberOfCores,NumberOfLogicalProcessorsĬPU clock speed is measured in megahertz (MHz).
On Linux, the value is obtained with the following command: # grep "cpu cores" /proc/cpuinfo If this information cannot be extracted from the system, NA is shown instead. The number of cores per CPU in the system.
