Compared with an information acquisition mode based on an embedded agent tool, the equipment information acquisition method provided by the embodiment of the application does not need to change the equipment to be migrated, does not introduce the setting threatening the safety to the equipment to be migrated, has higher safety, is a non-invasive investigation scheme, is more convenient to implement and has lower cost; compared with a mode of realizing information acquisition through monitoring, the application scenario of the equipment acquisition method provided by the embodiment of the application is cloud migration investigation, the method is used for comprehensively acquiring information of the investigated equipment to assist in formulating a cloud migration scheme, the required information can be acquired through single information acquisition, long-time monitoring on the equipment to be migrated is not needed, the time delay for acquiring a final investigation result is short, the investigation method is a low-time-delay investigation mode, the investigation efficiency can be improved, for an enterprise with a migration plan, the investigation cost is low, the cost performance is high, and the investigation requirement of the enterprise is met; in addition, the information acquired at one time in this embodiment is more comprehensive, and may include dynamic information such as CPU usage, memory usage, disk read/write times per second, network traffic per second, and the like, and may also include static information such as operating system version, CPU model, CPU core number, total memory amount, total disk amount, disk mount point, and the like.

When the device to be migrated needs to be monitored, the information acquisition method provided by the embodiment of the present application may also be implemented to monitor, for example, the information acquisition method provided by the embodiment of the present application is executed for multiple times. In addition, the information acquisition method provided by the embodiment of the application can also realize service discovery of the Windows system, wherein the service discovery refers to that a registry is used for recording information of all services in a distributed system, so that other services can quickly find the registered services.

The device information acquisition method provided by the embodiment of the application has better compatibility, and can be executed on various devices such as a physical machine, a Virtual machine, a cloud host and the like.

According to the device information acquisition method provided by the embodiment of the application, the current device is remotely connected to the WMI namespace of the device to be migrated, and the automatic acquisition of the configuration information of the device to be migrated can be realized in the WMI namespace through the information acquisition function of the WMI, so that the automatic investigation of the resources of the device to be migrated can be realized, and the efficiency, the accuracy and the standardization degree of the investigation are greatly improved compared with the manual investigation mode.

Optionally, in step S101, when the namespace of the system management tool of the device to be migrated is remotely connected, a remote connection request for remotely connecting the namespace may be sent to the device to be migrated, and when the device to be migrated successfully verifies the remote connection request, the namespace of the system management tool of the device to be migrated is remotely connected. The remote connection request may include authentication information of the electronic device for acquiring information, such as at least one of device identification, an Internet Protocol (IP) address, a user name, a password, and the like, which may be used to authenticate the identity. When the to-be-migrated device receives the authentication information, the authentication information can be verified, for example, the received authentication information is compared with the authentication information stored in the to-be-migrated device, and if the comparison is consistent, the authentication is determined to be successful, otherwise, the authentication fails, so that the current device can be ensured to have the connection and access permission to the namespace of the system management tool of the to-be-migrated device, and the security of remote connection can be improved.

In an optional implementation manner, the configuration information in the embodiment of the present application may be packaged information, that is, configuration information that is packaged as a class in advance and stored in a namespace of a system management tool, and in an example, the packaged configuration information may include at least one type of information such as attribute information, process information, and performance information, where the at least one type of information may be packaged as a class in advance and stored in a root/cimv2 namespace.

In one example, classes stored in the root/cimv2 namespace may include the following:

win32_ Processor, which represents a device capable of interpreting the instruction sequence on the computer running on the Windows operating system, and obtains the information of the device capable of interpreting the instruction sequence on the computer running on the operating system by calling the object, belonging to the attribute information;

win32_ Process, which represents the Process of the operating system and can obtain the Process information of the operation by calling the object;

a Win32_ operating system which represents a Windows-based operating system installed on the computer, and can acquire installation information on the operating system by calling the object, and belongs to attribute information;

win32_ DiskPartion, which represents the function and management capacity of the physical disk partition area on the computer system running Windows, and the information of the function and management capacity of the physical disk partition area on the computer system running Windows can be obtained by calling the object, and belongs to attribute information;

the CIM _ Processor represents the function and management of the Processor logic equipment, and can acquire the core number, the model and other related information of the Processor by calling the object, and belongs to attribute information;

win32_ performatteddata _ Tcpip _ network interface represents monitoring network state, and network related performance information, such as network transmission rate, can be acquired by calling the object.

In step S102, in the namespace of the system management tool, obtaining the configuration information of the device to be migrated through the information obtaining function of the system management tool includes: in the namespace of the system management tool, the configuration information is obtained by calling the class which encapsulates the configuration information.

In one example, a class encapsulating at least one of attribute information, process information, and performance information may be called in a root/cimv2 namespace to obtain the at least one of attribute information, process information, and performance information. The calling of a certain class in the root/cimv2 namespace can be realized by calling an SDK (Software Development Kit) provided by the class, and the SDK provided by the certain class is an interface provided by the class.

Compared with a manual acquisition mode and a mode of embedding an agent tool in the equipment to be migrated to realize information acquisition, the included configuration information can be directly acquired by calling the class in which the configuration information is encapsulated, so that automatic, standardized and non-invasive information acquisition can be realized,

in another optional implementation manner, the configuration information in the embodiment of the present application may be unpacked information, that is, configuration information that is not previously packed as a class and stored in a namespace of a system management tool, in this case, the configuration information cannot be obtained by calling the class, and in an example, the unpacked configuration information may include at least one of network information, an association relationship between a process and a port, an association relationship between a process and a file, and the like.

Optionally, in step S102, in the namespace of the system management tool, acquiring the configuration information of the device to be migrated through the information acquiring function of the system management tool may include: in the namespace of the system management tool, the configuration information (i.e. the unpackaged information) is stored in the registry by calling the class corresponding to the process, and the configuration information in the registry is acquired by calling the class corresponding to the registry.

When the unpackaged configuration information is stored in the registry through the class corresponding to the calling process, a command line process can be created through the class corresponding to the calling process, and the device to be migrated is controlled to execute the command line process so as to obtain the unpackaged configuration information and store the unpackaged configuration information in the registry.

In this embodiment of the present application, the class corresponding to the Process may be a Win32_ Process class in a root \ cimv2 namespace, and in a specific example, the Win32_ Process may be called in the root \ cimv2 namespace to create a command line Process, and the command line Process is executed to store the unpackaged configuration information in the registry.

In one example, the information acquisition command may be sent by the current device to a root \ cimv2 namespace of the device to be migrated, and the SDK provided by the Win32_ Process class in the root \ cimv2 namespace may create a command line Process in the root \ cimv2 namespace based on the received information acquisition command, so as to implement a function of storing the configuration information in the registry.

In this embodiment of the present application, a class corresponding to a registry may be used to implement operations such as obtaining configuration information in the registry, creating a folder, deleting a folder, and the like, and in an example, the class corresponding to the registry may be stdregpov (a class including a method related to the registry) in a root \ default namespace, and the stdregpov is a subclass in the root \ default namespace of WMI and includes a method related to the registry. The following functions can be achieved by the method contained in stdregpov: verifying a user's access rights, creating, enumerating, and deleting registry keys, creating, enumerating, and deleting keys, reading, modifying, and deleting data.

Under the condition that the configuration information is not packaged in advance and stored in the namespace of the system management tool, the configuration information cannot be acquired by calling the class in the namespace of the system management tool, the registry is a packaged object configured by the system, and collection of the non-packaged configuration information can be realized through the information transfer function of the registry.

In one example, the SDK provided by the Win32_ Process class may create a folder in the registry after receiving the information collection command sent by the current device, the unpackaged configuration information may be stored in the folder, and different folders may be created to store different configuration information during different information collection processes.

In one example, corresponding configuration information can be acquired from a folder created and stored with the configuration information in the information acquisition process, after the configuration information is acquired, the device to be migrated can be remotely controlled to delete the folder, so that interference of the left information on next information acquisition is avoided, if the information which is successfully remotely acquired is left in the registry, repeated information can be acquired in the next information acquisition process, accuracy of information research can be affected, and the folder for storing the information is deleted after each time of remote information acquisition is completed, so that acquisition of the repeated information can be reduced.

Based on the two ways of obtaining the configuration information, the packaged configuration information can be obtained, and the unpackaged configuration information can also be obtained, so that the information acquisition method of the embodiment of the application is more universal, and the requirements of different customers are met.

Fig. 2 shows a specific scenario of the device information acquisition method provided in the embodiment of the present application, and for information acquisition in a Windows system, referring to the scenario, the device information acquisition method may include: the method comprises the steps that a current server sends identity verification information to a server to be migrated, and after the server to be migrated successfully verifies the identity verification information, the WMI namespaces of the current server and the server to be migrated are remotely connected; the current server calls the class in the WMI namespace to acquire the configuration information contained in the WMI namespace; the current server sends an information acquisition command to the WMI namespace, the WMI SDK creates a command line process in the WMI namespace based on the command, and executes the command line process to acquire configuration information which is not packaged in advance and store the configuration information in a registry of the Windows system; the current server obtains configuration information of the registry.

Based on the same inventive concept, an embodiment of the present application further provides an apparatus migration method, as shown in fig. 3, the apparatus migration method may include:

s301, obtaining configuration information of the device to be migrated.

The configuration information can be acquired by executing the device information acquisition method provided by the embodiment of the application.

S302, determining a target cloud product matched with the configuration information in the candidate cloud products.

The candidate cloud product may include at least one of a pre-built virtual machine product, a container product, or other target instance product. The target cloud product determined based on the configuration information can be used as a migration target, and appropriate resources are provided for subsequent migration.

And S303, migrating the system function of the device to be migrated to the target cloud product.

According to the device migration method, the target cloud product can be determined based on the configuration information acquired remotely, so that the target cloud product can be matched with the configuration information of the device to be migrated, and therefore the system function of the device to be migrated can be migrated to the cloud resource which accords with the configuration characteristics of the device to be migrated.

Optionally, in step S302, determining a target cloud product matching the configuration information from the candidate cloud products may include: analyzing the configuration information to generate a data model, and determining a target cloud product in the candidate cloud products according to the data model; the data model may be a structured document for describing a resource configuration of the device to be migrated, for example, may be used to describe at least one of an attribute, a process, a performance, and the like of the resource on the device to be migrated, and may be used to screen out a target cloud product from the candidate cloud products, so that the target cloud product can provide the resource required for migration.

Optionally, the configuration information in the embodiment of the present application includes multiple types, and in step S302, determining a target cloud product matching the configuration information in the candidate cloud products may include: and screening target cloud products from the candidate cloud products based on various configuration information in sequence, wherein in two adjacent screening processes, the object of the next screening process is the result of the previous screening process. The multi-round screening is beneficial to pertinently screening out cloud products which accord with the configuration characteristics of the equipment to be migrated, and is convenient for the follow-up implementation and migration of the system functions of the migrated equipment.

In the case that the plurality of types of configuration information include two types of information, namely attribute information and performance information of the device to be migrated, a first cloud product matched with the attribute information may be determined in the candidate cloud products, the process may map the attribute information of the device to be migrated into the first cloud product, a second cloud product matched with the performance information may be determined in the first cloud product, the process may map the performance information of the device to be migrated into the second cloud product, and then the cloud server may be configured based on the second cloud product (as a target cloud product), or information of the second cloud product may be output, and the cloud server may be configured based on a cloud product (as a target cloud product) selected by a user from the second cloud product.

In one example, the performance information may include an average value, a maximum value, and a normal distribution value (3 σ normal distribution value) of data monitored for a specified monitoring duration, and the second cloud product may be further screened out from the first cloud product based on the performance information.

The first cloud product may be a default cloud product set for attribute information, and in one example, the first cloud product may be an ECS (Elastic computing Service) product, which is a product of cloud computing services at IaaS (Infrastructure as a Service) level, and the product has high stability and reliability and is elastically extensible.

Under the condition that the multiple kinds of configuration information include three kinds of information, namely attribute information, process information and performance information of the device to be migrated, a second cloud product matched with the attribute information, the process information and the performance information can be determined in the candidate cloud products, the process can map the attribute information and the process information of the device to be migrated into the second cloud product, further, a fourth cloud product matched with the performance information can be determined in the second cloud product, the process can map the performance information of the device to be migrated into the fourth cloud product, a cloud server can be configured based on the fourth cloud product (serving as a target cloud product), or information of the fourth cloud product is output, and the cloud server is configured based on a cloud product (serving as a target cloud product) selected by a user from the fourth cloud product.

In one example, the implementation manner of selecting the target cloud product for constructing the cloud server from the candidate cloud products according to the attribute information, the process information and the performance information of the device to be migrated is as follows:
