The present invention can be embodied in many different forms and is not limited to the embodiments described here.

Figure 1 shows a schematic flow chart of a method for evaluating and displaying CPU usage in an embodiment of the present invention.

Applied to baseboard management controllers, since the CPU usage affects the CPU operating frequency and CPU power consumption, there is an approximately linear relationship between CPU power consumption and CPU utilization. In the server management system, the baseboard management controller can directly obtain the CPU power consumption. This solution uses the CPU power consumption to estimate the CPU usage.

The methods include:

Step S1: Based on the obtained attribute information of the target CPU device, obtain idle power consumption information and thermal power consumption information corresponding to the target CPU device.

In one embodiment, step S1 includes:

Obtain model information corresponding to the target CPU device from the target CPU device;

Idle power consumption information in an idle state and thermal power consumption information in a full load state corresponding to the target CPU device are obtained based on the model information. Specifically, when the target CPU device is in an idle state, that is, the CPU usage rate is 0, there will be a basic power consumption, that is, idle power consumption information; the basic power consumption increases as the CPU usage rate increases, until the maximum power consumption is TDP power consumption is also the maximum power consumption of the CPU under normal working conditions, that is, thermal power consumption information. The idle power consumption information and thermal power consumption information can be obtained by the baseboard management controller through the model information of the target CPU device.

Step S2: Based on the idle power consumption information and thermal power consumption information of the target CPU device, calculate the corresponding CPU usage rate according to the current power consumption information of the target CPU device obtained in real time, and record the calculated CPU usage rate and display.

In one embodiment, calculating the corresponding CPU usage based on the current power consumption information of the target CPU device obtained in real time based on the idle power consumption information and thermal power consumption information of the target CPU device includes:

Obtain the current power consumption information of the target CPU device from the core power supply chip (motherboard VR) of the target CPU device; the baseboard management controller obtains the current power consumption or instantaneous power consumption of the target CPU device through the motherboard VR, and this value is equal to CPU usage is closely related.

The corresponding CPU usage is calculated according to the idle power consumption information, thermal power consumption information and current power consumption information of the target CPU device.

In one embodiment, calculating the corresponding CPU usage based on the idle power consumption information, thermal power consumption information and current power consumption information of the target CPU device includes:

Based on the CPU usage calculation formula related to the near-linear relationship between CPU power consumption and CPU usage, the corresponding CPU usage is calculated according to the idle power consumption information, thermal power consumption information and current power consumption information of the target CPU device .

Among them, the CPU usage determines the CPU power consumption, and the CPU usage has a roughly linear relationship with the CPU power consumption.

Then the relationship between CPU power consumption and CPU usage is as follows:

P _CPU = (P _{CPU_TDP} -P _{CPU_IDLE} )*CPU _USEAGE +P _{CPU_IDLE} ; (1)

Among them, CPU _USEAGE is the CPU usage, P _CPU is the current power consumption information, P _{CPU_IDLE} is the idle power consumption information, and P _{CPU_TDP} is the thermal power consumption information.

In a specific embodiment, it can be seen from the above linear relationship between CPU power consumption and CPU usage that the calculation formula for obtaining the CPU usage through derivation includes:

And among them, CPU _USEAGE is the CPU usage, P _CPU is the current power consumption information, P _{CPU_IDLE} is the idle power consumption information, and P _{CPU_TDP} is the thermal power consumption information.

In one embodiment, the CPU usage is displayed in a percentage display mode on the WEB console interface of the baseboard management controller.

In order to better explain the above CPU usage evaluation and display method, the present invention provides the following specific embodiments.

Embodiment 1: A CPU usage evaluation and display method.

Applied to BMC to evaluate the CPU usage of 245W CPU; as shown in Figure 2, the steps to implement the CPU usage evaluation and display method are as follows:

Step 2: After receiving the power-on signal, the CPU initializes and starts working.

Step 3: The BMC obtains the CPU model from the CPU, and further obtains the P _{CPU_TDP} information when the CPU is fully loaded and the P _{CPU_IDLE} information when the CPU is idle.

Step 4: BMC obtains the power consumption information of the CPU through CPU VR.

Step 5: Calculate CPU utilization based on power consumption information.

Step 6: Record the CPU usage and display the CPU usage information on the BMC WEB.

Step 7: If no shutdown signal is received, the BMC loops to calculate the CPU usage.

Step 8: Receive shutdown signal, end.

As shown in Figure 3, it is a schematic diagram of the trend table of CPU usage and CPU power consumption of the 245W CPU. When the CPU is idle, power consumption is around 45 watts. As utilization increases, power consumption gradually increases until the power consumption reaches the maximum power consumption of the CPU. It can be seen from Figure 3 that there is basically a linear relationship between the power consumption of the CPU and the CPU usage. This embodiment uses this law to estimate the CPU usage.
