Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to fig. 1, a system architecture diagram of a server resource monitoring method provided in an embodiment of the present application is shown, where the system includes: the system comprises a server, a virtualization management system, an operating system, an operation and maintenance server and a control card.

Specifically, the Server may be a Bare Metal Server (BMS), that is, a Bare Metal architecture (native architecture) Server, and the Server may include a hardware layer and a software layer, where the hardware layer includes: conventional hardware such as a cluster of processors, including at least one processor, memory, etc. The software layer comprises an operating system and a virtualization management system, under the bare metal framework, the operating system can directly access resources of the server, and in the process that a client accesses hardware resources of the server through the operating system, the client does not need to share the hardware resources of the server with other clients, so that the performance of the server can be fully mined, and the effect of monopolizing the resources of the client as a physical machine can be achieved. It should be noted that after a client applies for a virtual machine service, one or more servers may be provided for a server providing a virtual machine to the client, and a single server may be a minimum unit providing resources.

The virtualization management system (Hypervisor) is software or firmware used to build and execute a virtual machine, and is also an intermediate software layer running between a physical server and an operating system. In the embodiment of the present application, the virtualization management system may be a bare-metal virtualization management system (bare-metal hypervisors), the virtualization management system may be directly installed on hardware of the server, a hardware full-emulation instance is created by using hardware resources of the server, the virtualization management system directly manages and calls the hardware resources, a bottom operating system is not required, and the virtualization management system may also be regarded as a thin operating system.

The operating system of the client may be a Virtual Machine (Virtual Machine) running on the server, which is a complete computer system having a complete hardware system function and running in a completely isolated environment, and the client may access and utilize the hardware resources of the server through the operating system to implement the related business operations.

The control card can include a network port, the control card is used as the only communication hardware between the operating system and the server, on one hand, the control card is used as a device of a high-speed serial computer expansion bus standard (PCI-Express) to be accessed into the server, data can be exchanged with the server through a PCIe interface, on the other hand, the network interface of the control card can be linked with a back-end operation and maintenance server, and interconnection and intercommunication between the data and the back end are realized.

Further, referring to fig. 2, an architecture diagram of a control card provided in an embodiment of the present application is shown. Specifically, an example under a bare metal architecture is shown, a processor and a memory are arranged in a server, the processor and the memory are physical hardware, in addition, the server also supports VirtiO-NIC and VirtiO-Blk (VirtiO-NIC and VirtiO-Blkirtio are semi-virtualization schemes defined by VirtiO specifications, VirtiO is an abstraction layer located above equipment in a semi-virtualization management system), and thus all images on the cloud, all systems on the cloud, virtual machines and physical machines can be completely compatible. In addition, in order to implement the example, an external device is also required, and the external device is simulated in a device form through a chip by a keyboard, a mouse, a display and the like. The whole virtualization management layer can run completely on the control card, and the control card can also support a Cloud disk, a Virtual Private Cloud (VPC) network, a Server Load Balancing (SLB), and hot plug of storage/network devices. The control management chip can be connected with the VPC interface/SLB interface and the cloud disk interface so that the control card is connected to the VPC/SLB network and the cloud disk.

In this embodiment of the application, in the case that the management and control command is received, step S1 is executed, and the first processor in the processor cluster receives the start request.

Specifically, referring to fig. 1, the first processor may be a processor 2 in the processor cluster, the start request may be an interrupt request sent by the control card to the first processor through an interrupt pin, a hard wire may be led out from a General Purpose Input/Output interface pin (GPIO) of the control card to the interrupt pin of the first processor in the processor cluster, and the control card may generate an interrupt request to the first processor in the processor cluster under the trigger of a management and control command. The number of the first processors having the interrupt pins may be one or more, and it should be noted that the control card may be connected to the interrupt pin of one first processor, and the control card may also be connected to respective interrupt pins of a plurality of first processors, which is not limited in this embodiment of the present application.

The Interrupt pin may be a System Management Interrupt pin (SMI pin), and the Interrupt request may be a System Management Interrupt request (SMI), where the SMI Interrupt request is triggered by hardware and is an Interrupt processed by a Basic Input Output System (BIOS), and after the SMI Interrupt request is triggered, the first processor enters a System Management Mode (SMM), and at this time, an execution flow related to the operating System is suspended to execute an Interrupt Service Routine (ISR) registered in the BIOS.

It should be noted that the Interrupt request may also be a Non-Maskable Interrupt (NMI) in the SMI Interrupt request. Non-maskable interrupts are one type of interrupt request that is used to notify the first processor that a catastrophic event has occurred, such as a power down, a bus parity bit error, etc. In addition, in the embodiment of the application, the SMI interrupt request can not occupy the resources of the operating system, so that the stability of the operating system is improved.

Further, an interrupt request is a request (e.g., an electrical pulse signal) to the first processor to stop the current processing event and to process another higher priority event.

After the serial management interface receives the interrupt request, the first processor may execute step S2, where the first processor starts the virtualization management system in the server according to the start request; the virtualization management system runs outside the operating system.

In this step, the first processor may perform interrupt processing according to the interrupt request, that is, control the first processor to stop a current processing event, and perform an operation of starting the virtualization management system in the server by the virtual processor after converting the first processor into the virtual processor. Specifically, referring to fig. 1, when the operation of the virtualization management system is started in the server, a preset space with a preset size may be reserved for a preset position in the memory of the server, so as to install the virtualization management system and store data of the virtualization management system.

Step S3 may be performed by the virtualization management system determining a target processor from the processor cluster and setting an operating state of the target processor to a physical processor operating state.

Referring to fig. 1, a plurality of processors may be provided in a processor cluster of a server, and during a process in which a client accesses hardware resources of the server through an operating system, the processors may be allocated as virtual processors of the operating system so as to operate in a virtual processor operating state. In this step, the virtualization management system may determine a target processor from the processors in the processor cluster, convert the current operating state of the target processor from the virtual processor operating state to the physical processor operating state, so that the target processor exits the current virtual processor mode and returns to the normal hardware processor mode, and after the target processor returns to the physical processor operating state, the target processor is completely handed back to the server by the operating system and has the right to collect the resource usage information of the server.

For example, referring to FIG. 1, the virtualization management system may determine processor 2 in the processor cluster as a target processor and set an operating state of the target processor to a physical processor operating state.

Step S4 is executed, and the target processor obtains the resource usage information of the server.

After the target processor exits the current virtual processor mode and returns to the normal processor mode, the target processor collects resource use information of the server, wherein the resource use information comprises but is not limited to memory use information, processor temperature information and processor performance information of the server. The resource use information is sourced from the hardware of the server and has high authenticity, so that the data accuracy of the resource use information is high, and the utilization value is high.

In the embodiment of the application, the current running state of the target processor is changed into the running state of the physical processor under the control of the virtualization management system, so that the target processor is completely handed back to the server from the operating system, and then the resource use information acquisition process executed by the target processor does not occupy the resources of the operating system, thereby reducing the interference to the operating system and improving the stability of the operating system.

Step S5 is executed, and the target processor sends the resource usage information to the target device.

In one implementation, referring to fig. 1, since the control card is provided with a network port, the control card may send the resource usage information to a remote operation and maintenance server through the network port, so as to implement collection of the resource usage information by the operation and maintenance personnel.

In another implementation, the target processor may also send the resource usage information to the remote operation and maintenance server through the output interface of the network card on the server and the operation and maintenance management tool instead of sending the resource usage information to the control card.

In an embodiment of the present application, a first processor in a cluster of processors receives a boot request; the first processor starts a virtualization management system in the server according to the starting request; the virtualization management system runs outside the operating system; the virtualization management system determines a target processor from the processor cluster and sets the running state of the target processor as the running state of a physical processor; the target processor acquires resource use information of the server; the target processor sends the resource usage information to the target device. In the invention, the running state of the target processor is changed into the running state of the physical processor under the control of the virtualization management system, and then the target processor can collect the resource use information of the server hardware in the running state of the physical processor, so that the resource use information which comes from the server hardware and has higher accuracy is collected, and the operation and maintenance management efficiency of the server is improved.

Referring to fig. 3, a flowchart of a server resource monitoring method according to an embodiment of the present application is shown, where the method specifically includes the following steps:

in step 101, a first processor in the processor cluster receives a boot request.

Specifically, the start request may be an interrupt request, and the sender of the interrupt request may be a control card or an operating system.

It should be noted that the sending process of the interrupt request may include two ways, that is, in a case that the control card receives the management and control command, the control card sends the interrupt request to the serial management interface; in a second mode, an Interrupt request is directly initiated to the first processor of the server through a kernel module of the operating system, so as to implement Interrupt processing of the first processor, and the kernel module can be implemented based on an Interrupt Descriptor Table (IDT).

Step 102, the first processor starts a virtualization management system in the server according to the starting request; the virtualization management system runs outside the operating system.

In this step, the first processor controls the first processor to stop the current processing event according to the start request, and performs an operation of starting the virtualization management system in the server by the virtual processor after converting the first processor into the virtual processor. Specifically, referring to fig. 1, when the operation of the virtualization management system is started in the server, a preset space with a preset size may be reserved for a preset position in the memory of the server, so as to install the virtualization management system and store data of the virtualization management system.

Specifically, the design of the virtualization management system must be light enough, so that the purpose of rapidness and high efficiency can be achieved in the process of inserting the virtualization management system between the server and the operating system.

In the embodiment of the present application, the design of the virtualization management system may be based on a memory model, that is, the virtualization management system occupies a small memory (about 32 megabytes) of the server. In addition, an address mapping table is stored in the virtualization management system, and the address mapping table comprises mapping between an address of the operating system accessing the preset space and a machine physical address of the virtualization management system, so that address mapping can be realized based on the address mapping table in each access, and the purpose of correct access is achieved.

Furthermore, the design of the virtualization management system can be based on an interrupt/device model, that is, the virtualization management system only executes the interrupt request sent by the interrupt pin of the first processor, and sends other interrupt requests to the operating system for processing, so that the system overhead of the virtualization management system can be greatly reduced, and the light weight effect of the virtualization management system is further improved.

Furthermore, the design of the virtualization management system can be based on a processor model, namely, the first processor of the server and the virtual processors distributed to the operating system are subjected to 1:1 mapping, so that the scheduling and multiplexing of the virtual processors are eliminated, the system overhead of the virtualization management system is further reduced, and the light weight effect of the virtualization management system is improved.

Step 103, the virtualization management system determines a target processor from the processor cluster, and sets the running state of the target processor as a physical processor running state.

In this step, referring to fig. 1, a plurality of processors may be disposed in a processor cluster of the server, and in the process that a client accesses hardware resources of the server through an operating system, the processors may be allocated as virtual processors of the operating system, so as to operate in a virtual processor running state. In this step, the virtualization management system may determine a target processor from the processors in the processor cluster, convert the current operating state of the target processor from the virtual processor operating state to the physical processor operating state, so that the target processor exits the current virtual processor mode and returns to the normal hardware processor mode, and after the target processor returns to the physical processor operating state, the target processor is completely handed back to the server by the operating system and has the right to collect the resource usage information of the server.

Step 104, the target processor obtains resource usage information of the server.

And 105, the target processor sends the resource use information to the target device.

In this step, the target device may be a control card, and the target processor may send the resource usage information to the control card, so that the operation and maintenance staff may collect the resource usage information through the control card.

In one implementation, referring to fig. 1, since the control card is provided with a network port, the control card may send the resource usage information to a remote operation and maintenance server through a network, so as to implement collection of the resource usage information by the operation and maintenance personnel.

In another implementation, the target device may be an operation and maintenance server, and the target processor may also send the resource usage information to the remote operation and maintenance server through an output interface of a network card on the server and the operation and maintenance management tool instead of sending the resource usage information to the control card.

To sum up, a server resource monitoring method provided by the embodiment of the present application includes: a first processor in the processor cluster receives a startup request; the first processor starts a virtualization management system in the server according to the starting request; the virtualization management system runs outside the operating system; the virtualization management system determines a target processor from the processor cluster and sets the running state of the target processor as the running state of a physical processor; the target processor acquires resource use information of the server; the target processor sends the resource usage information to the target device. In the invention, the running state of the target processor is changed into the running state of the physical processor under the control of the virtualization management system, and then the target processor can collect the resource use information of the server hardware in the running state of the physical processor, so that the resource use information which comes from the server hardware and has higher accuracy is collected, and the operation and maintenance management efficiency of the server is improved.

Referring to fig. 4, a specific flowchart of a server resource monitoring method according to an embodiment of the present application is shown, where the method specifically includes the following steps:

in step 201, a first processor in a processor cluster receives a boot request.

This step may specifically refer to step 101, which is not described herein again.

Optionally, referring to fig. 1, the server further includes a control card, and the control card is connected to the first processor; step 201 may specifically include:

in sub-step 2011, a first processor in the processor cluster receives a start request sent by the control card.

Optionally, step 2011 may also be implemented by receiving, by the first processor in the processor cluster, an interrupt request sent by the control card through an interrupt pin.

Referring to fig. 1, the control card is connected to an interrupt pin of the first processor. It should be noted that the control card may be connected to an interrupt pin of one first processor, and the control card may also be connected to respective interrupt pins of multiple first processors, which is not limited in this embodiment of the present application.

Specifically, referring to fig. 1, an interrupt pin hardwired to the first processor of the bare metal server may be led out from the control card, so that the control card may generate an interrupt request to the first processor of the server under the trigger of the management and control command.

Optionally, step 201 may specifically include:

substep 2012, a first processor in the cluster of processors receives a boot request sent by the operating system.

In the application, Interrupt processing of the first processor can be realized by directly initiating an Interrupt request to the first processor of the bare metal server through a kernel module of the operating system, and the kernel module can be realized based on an Interrupt Descriptor Table (IDT).

Step 202, the first processor starts a virtualization management system in the server according to the start request; the virtualization management system runs outside the operating system.

This step may specifically refer to step 102, which is not described herein again.

Optionally, step 202 may specifically include:

in sub-step 2021, the first processor starts the virtualization management system according to the start request, and provides a preset space in the memory of the server to the virtualization management system for use.

Optionally, the preset space in the memory is a space with a preset size in addresses from 1MB to 4 GB.

Referring to fig. 5, a memory relationship diagram between an operating system and a server memory provided in the application embodiment is shown, where a memory size of the server is 4 gigabytes, and a design of the virtualization management system may be based on a memory model, that is, if the virtualization management system occupies a very small memory of the server (assumed to be about 32 megabytes), a preset space of 32 megabytes may be reserved in a current memory of the server to store data of the virtualization management system, and the preset space of 32 megabytes may be set at a tail of the memory from a1 st megabyte to a4 th gigabyte, because an access frequency of the operating system to the tail space of the memory is very low, which can reduce interference on a client in normally using the operating system.

Optionally, in the substep 2021, the virtualization management system may be further started by the first processor according to the start request, and the preset space in the memory is provided to the virtualization management system for use by a memory layout entry in the basic input output system of the server.

Specifically, the determination of the preset space of the preset size in the memory of the server may be implemented by the first processor through a memory layout entry in the BIOS of the server according to the interrupt request. The memory layout table entry may be an E820 table entry.

In the embodiment of the present application, a preset space with a preset size may be specifically reserved in the memory of the server through an E820 entry in the BIOS of the server, and since the BIOS of the server is a part of the basic service of the service provider and cannot be modified by a non-developer, the preset space is safe and available.

Due to the fact that the design of the virtualization management system is light enough, the data of the virtualization management system is stored in the preset space, and the purpose of high speed and accuracy can be achieved in the process of collecting resource use information by using the virtualization management system.

Optionally, the physical address of the client of the operating system is mapped in one-to-one correspondence with the physical address of the machine of the server.

The Guest Physical Address (GPA) is an address of the operating system accessing the preset space, and the Machine physical address (HPA) is a physical address of the virtualization management system.

For an operating system, memory is a continuous address space with physical addresses starting from 0. In a virtualization environment, what really has a physical memory is a virtualization management system, and only one physical memory of the virtualization management system is needed, the virtualization management system needs to simulate a virtual memory which can be used as the physical memory for each operating system on a server, and the virtualization management system simulates a new layer of address space: guest physical address space, which the operating system considers to be machine physical address space, but which is not the final machine physical address space of the server.

Due to the introduction of guest physical addresses for the operating system, the memory address translation process becomes: from guest physical address GPA to machine physical address HPA. The translation from GPA to HPA is determined by the virtualization management system, which determines the translation from GPA to HPA when allocating physical memory to the operating system, and the mapping relation is recorded by the internal data structure in the virtualization management system, which dynamically maintains an address mapping table between the GPA as guest physical address and HPA as machine physical address for the operating system.

In the embodiment of the application, an address mapping table is stored in a preset space corresponding to a virtualization management system, the address mapping table includes a mapping relationship between a guest physical address and a machine physical address, the guest physical address is an address of an operating system accessing the preset space, the machine physical address is a physical address of the virtualization management system, and the machine physical address has uniqueness.

Specifically, by mapping between the address of the preset space accessed by the operating system and the machine physical address of the virtualization management system, address mapping can be realized based on the address mapping table in each access, so that the purpose of correct access is achieved, if the correct access is performed in each access, no error report is generated on the operating system, interference on the operating system is reduced, and no difference in memory access is caused on the operating system in the prior art by operation and dynamic loading/removal of the virtualization management system.

It should be noted that the establishment of the mapping relationship between the physical address of the client and the physical address of the machine, and the operation of calling the mapping relationship in the subsequent access process, may be implemented by an Extended Page Table (EPT) technique, and the ERT technique is a virtualized address translation hardware technique of intel corporation, and can directly support the address translation from GPA to HPA on hardware, thereby greatly improving the performance of memory virtualization, and greatly reducing the difficulty of memory virtualization.

Step 203, the virtualization management system selects one virtual processor from the virtual processors in use by the operating system to determine as the target processor; the running state of the virtual processor being used by the operating system is a virtual processor running state.

Wherein each of the first processors is configured as a virtual processor for use by the operating system. Specifically, the 1:1 mapping between the physical first processor of the server and the virtual processors allocated to the operating system eliminates the scheduling and multiplexing of the virtual processors, further reduces the system overhead of the virtualization management system, and improves the light weight effect of the virtualization management system.

Referring to fig. 1, a plurality of first processors may be disposed in a server to form a processor cluster, and during a process that a client accesses hardware resources of the server through an operating system, the processors may be allocated as virtual processors of the operating system to operate in a virtual processor operating state, which may also be referred to as a non-root mode operating state,

step 204, switching the running state of the target processor from the running state of the virtual processor to the running state of the physical processor.

In this embodiment of the present application, the current operating state of the target processor may be converted from the virtual processor operating state to the physical processor operating state, so that the target processor exits the current virtual processor mode and is restored to the normal hardware processor mode, after the target processor is restored to the physical processor operating state, the target processor is completely handed back to the server by the operating system and has the authority to acquire the resource usage information of the server, and the physical processor operating state may be referred to as a root mode operating state. The root mode means that the target processor can completely control the bottom layer of the server and the system file to acquire the authority of acquiring the resource use information.

The virtualization management system and the operating system share underlying server processor resources, so the server requires a physical memory area to automatically save or restore the context of each other's execution. This Area is called a Virtual-Machine Control Structure (VMCS), and includes a Guest State Area (Guest State Area), a Host State Area (Host State Area), and an execution Control Area.

When the virtual machine is inserted, the server automatically loads the context of the operating system from the client state area, when the virtualization management system starts to run, the virtualization management system cannot be interfered by the operating system, and the virtualization management system can automatically switch to the operating system only after completely processing the work. The next operation of the virtualization management system is necessary to process a new event, so that the virtualization management system starts to execute from a general event processing function each time the virtual machine is inserted. When a mode switching operation event (VMExit, Virtual-Machine Exit) is executed, the server automatically saves the context of the operating system in the client state area, loads the address of the general event processing function of the virtualization management system from the host state area, and the virtualization management system starts executing.

In this step, the virtualization management system may trigger a mode switching operation event at regular time by using a timer configurable by the VMCS, so as to switch the running state of the target processor from the virtual processor running state to the physical processor running state.

In step 205, the target processor obtains resource usage information of the server.

This step may specifically refer to step 104, which is not described herein again.

The resource usage information includes: at least one of memory usage information, processor temperature information, processor performance information. Through the information, operation and maintenance personnel can accurately judge the current service performance of the server, and the operation and maintenance management of the server is realized according to the judgment of the performance.

Step 206, the target processor sends the resource usage information to the target device.

The step may specifically refer to the step 105, and is not described herein again.

Optionally, the target device is the control card, and step 206 may specifically include:

sub-step 2061, the target processor sends the resource usage information to the control card.

And a substep 2062, sending the resource usage information to the operation and maintenance server by the control card.

Referring to fig. 1, since the control card is provided with a network port, the control card may send the resource usage information to a remote operation and maintenance server through a network, so as to collect the resource usage information by the operation and maintenance personnel.

Optionally, the target device is an operation and maintenance server, and step 206 may specifically include:

in sub-step 2063, the target processor sends the resource usage information to the operation and maintenance server.

Optionally, the server further includes a network card, and the substep 2063 may also be implemented in a manner that the target processor sends the resource usage information to the operation and maintenance server through the network card.

Specifically, the target processor may send the resource usage information to the remote operation and maintenance server through the output interface of the network card on the server and the operation and maintenance management tool instead of sending the resource usage information to the control card.

sub-step 2064, the target processor sends the resource usage information to the operation and maintenance server.

Substep 2065, the operation and maintenance server sends the resource usage information to the client when receiving the query request sent by the client.

The query request may be sent by a client, and the client may be a terminal running an operating system of a user.

In the embodiment of the application, the resource use information is provided for the operation and maintenance server, so that the operation and maintenance personnel can realize the operation and maintenance management; the resource use information can be further provided for the user of the client by the operation and maintenance server, so that the user can know the resource use condition of the purchased server.

Specifically, after logging in an account in a client and implementing account verification, an operating system of a user may send a query request to an operation and maintenance server, and the operation and maintenance server may add the resource usage information to a response to the query request according to the query request.

In step 207, the virtualization management system is removed after running for a preset time.

In the embodiment of the present application, the insertion and removal of the virtualization management system is a fast process, and can be completed within 1-2 milliseconds generally. Once the virtualization management system is plugged in, it may have no impact on the performance of the server due to its sufficiently lightweight. The virtualization management system will automatically remove after running for 20-30 milliseconds.

Optionally, after step 206, the embodiment of the present application may further include:

step A1, the target processor determines the load value of the server according to the resource usage information.

In the embodiment of the present application, the resource usage information includes, but is not limited to, memory usage information of a server, processor usage information, processor temperature information, and processor performance information. The resource use information is sourced from the hardware of the server and has high authenticity, so that the data accuracy of the resource use information is high, and the utilization value is high.

The target processor can calculate a load value of the server according to the resource use information, wherein the load value is used for reflecting the current computing power state of the server. The efficiency of processing the job by the server is reduced due to the overlarge load value of the server, which indicates that the hardware bearing computing capacity of the server of the user is weak at this time, and the improvement and optimization can be performed by increasing the hardware. The load value of the server is too small, which indicates that the utilization rate of the hardware of the server of the user is low at the moment, and the optimization can be improved in a mode of increasing the calculation workload.

Step A2, the operation and maintenance server counts the time length when the load value of the server is greater than or equal to the preset load value.

Step A3, if the duration is greater than or equal to a preset time threshold, the operation and maintenance server sends a capacity expansion prompt message to the client.

The client may be a terminal running an operating system of a user.

In this embodiment of the present application, the target processor may count the size of the load value of the server in real time according to the received resource usage information, and when the duration that the load value of the server is greater than or equal to the preset load value is greater than or equal to the preset time threshold, the server is considered to be in the overload state for a long time, at this time, the target processor may control the server to generate capacity expansion prompting information, and send the capacity expansion prompting information to the client for display, where the capacity expansion prompting information includes information for increasing the number of processors in the processor cluster, and the capacity expansion prompting information may notify the client that the current server is in the overload state for a long time, and please add an additional processor in the processor cluster, so as to improve the computing capability of the server and achieve the purpose of elastic capacity expansion.

Optionally, the embodiment of the present application may further include:

step a4, when the target processor finishes acquiring the resource usage information, the virtualization management system switches the running state of the target processor from the physical processor running state to a virtual processor running state.

In the embodiment of the present application, the insertion and removal of the virtualization management system is a fast process, and can be completed within 1-2 milliseconds generally. Once the virtualization management system is plugged in, it may have no impact on the performance of the server due to its sufficiently lightweight. The virtualization management system automatically removes the operation state of the target processor after continuously operating for 20-30 milliseconds, switches the operation state of the target processor from the physical processor operation state to the virtual processor operation state again, and returns the target processor to the operating system of the client for use after virtualization.

Step a5, determining, by the control card, whether the monitoring operation of the resource usage information of the server is normal according to the change information of the operating mode of the first processor.

In the embodiment of the present application, based on the detectability of the server resource monitoring method provided by the present application, an implementation is provided for monitoring whether a virtualization management system is inserted between the server and the operating system, in this implementation, a status tag in a processor identifier may be extracted by continuously checking processor identification information (CPU ID, which is an x86CPU instruction) of the first processor, and by determining a switching condition of the status tag, it is determined by the control card whether a monitoring operation on the resource usage information of the server is normal, that is, it is determined that the virtualization management system is inserted between the server and the operating system.

For example, the state tag of leave 0, which is a 12-bit string, may be read from the CPU ID, and is "KVMKVMKVM" when the processor is in a non-root mode and is allocated to the operating system under the Virtual Machine (KVM); when the processor is in root mode and is allocated under the virtualization management system (Hypervisor) of the embodiment of the present application, the status label is "Hypervisor".

Therefore, by judging the status label, when the status label is switched back and forth from the label "KVMKVMKVM" to the label "HyperVxxx", it is determined that the current first processor is switched back and forth in the root mode and the non-root mode, and it is determined that the monitoring operation of the resource usage information of the server by the control card is normal, that is, it is determined that the virtualization management system is inserted between the server and the operating system.

Optionally, step a5 may also be implemented by running an open-source system virtualization module in the operating system. And if the operating system generates error reporting information, determining that the virtualization management system is inserted between the server and the operating system for implementation.

In the embodiment of the present application, based on the detectability of the server resource monitoring method provided by the present application, another implementation manner is provided, because the Virtualization management system adopts an Intel VT (Intel Virtualization Technology) hardware Virtualization Technology. Because Intel VT allows a processor to operate as if multiple processors were running in parallel, it is possible to run multiple operating systems simultaneously within a server. However, because the Intel VT conflicts with the bare metal architecture, a KVM (Kernel-based Virtual Machine) supported by the Intel VT and a virtualization management system under the bare metal architecture of the present application cannot exist at the same time, and thus when the KVM is run on a server of the bare metal architecture, an error is reported due to incompatibility between the Intel VT and the bare metal architecture.

Therefore, if the KVM with VT hardware function support is restarted in the operating system, an error cannot be reported because the Intel VT cannot be used, and therefore, when installing the KVM in the operating system to start virtualization, if error information is generated, it is determined that the virtualization management system is inserted between the server and the operating system.

To sum up, a server resource monitoring method provided by the embodiment of the present application includes: a first processor in the processor cluster receives a startup request; the first processor starts a virtualization management system in the server according to the starting request; the virtualization management system runs outside the operating system; the virtualization management system determines a target processor from the processor cluster and sets the running state of the target processor as the running state of a physical processor; the target processor acquires resource use information of the server; the target processor sends the resource usage information to the target device. In the invention, the running state of the target processor is changed into the running state of the physical processor under the control of the virtualization management system, and then the target processor can collect the resource use information of the server hardware in the running state of the physical processor, so that the resource use information which comes from the server hardware and has higher accuracy is collected, and the operation and maintenance management efficiency of the server is improved. In addition, the control card is connected with a terminal pin of the first processor, the control card sends a starting request to the first processor, then the virtualization management system controls a target processor to enter a physical processor running state to acquire resource use information, coupling with a processor used by an operating system of a client when the resource use information is acquired is avoided, interference of the acquisition process of the resource use information on the operation of the operating system of the client is avoided, and the operation stability of the operating system of the client is improved.
