[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The configuration item connectivity analysis method embodiment provided in the present application embodiment can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a method for analyzing connectivity of a configuration item according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0025] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the connectivity analysis method of the configuration items in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0026] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0027] In this embodiment, a method for analyzing connectivity of configuration items running on the above mobile terminal or network architecture is provided. Figure 2 is a flow chart of a method for connectivity analysis of configuration items according to an embodiment of the present invention, such as Figure 2 As shown, the process includes the following steps:

[0028] Step S202, obtaining a set of entities to be checked, wherein the set of entities to be checked includes a plurality of configuration items to be checked, and the configuration items are entity objects managed in operation and maintenance;

[0029] The above configuration items are operation and maintenance objects that need to be included in the scope of configuration management to support the operation and maintenance of the bank's production and disaster recovery systems. The scope of the above configuration items includes IT infrastructure (such as cabinets, servers, network equipment, storage devices, operating systems), cloud products (such as cloud servers, cloud storage, cloud databases), and other objects that need to be managed in operation and maintenance, such as: physical subsystems, etc. The above configuration items to be checked constitute the above entity set to be checked.

[0030] Step S204: analyzing the connectivity of the configuration items in the set of entities to be checked through an operation and maintenance knowledge graph, wherein the operation and maintenance knowledge graph is a graph constructed based on the relationships between the configuration items managed in the operation and maintenance.

[0031] The above-mentioned operation and maintenance knowledge graph is a topological network relationship graph constructed based on configuration item entity data (including hardware data and software data) and configuration item relationship model. The above-mentioned operation and maintenance knowledge graph is used to analyze the connectivity of the configuration items of the above-mentioned set of entities to be checked.

[0032] Specifically, each configuration item in the set of entities to be checked is determined as a source configuration item; a target configuration item is determined in the operation and maintenance knowledge graph, wherein the target configuration item is any configuration item in the operation and maintenance knowledge graph except the source configuration item; and the connectivity of the source configuration item is analyzed according to the operation and maintenance knowledge graph, the source configuration item and the target configuration item.

[0033] The above-mentioned source configuration item is any configuration item in the above-mentioned set of entities to be checked, which serves as the starting point for determining connectivity. The above-mentioned target configuration item is any node other than the source configuration item set according to the above-mentioned knowledge graph, which serves as the end point for determining connectivity. The above-mentioned target configuration item entity is not necessarily the final node in the physical sense, but can be the operation and maintenance knowledge graph node corresponding to any configuration item entity. For example, if the source configuration item is set to "cloud server host", the target configuration item is set to "physical subsystem".

[0034] Specifically, a link from the source configuration item to the target configuration item is determined in the operation and maintenance knowledge graph to obtain multiple links; and the connectivity of the source configuration item is analyzed according to the reachability of each of the links, wherein the reachability refers to whether the source configuration item and the target configuration item in each of the links are connected.

[0035] Optionally, a link among the multiple links that is connected between the source configuration item and the target configuration item is determined as a reachable link; and a link among the multiple links that is not connected between the source configuration item and the target configuration item is determined as an unreachable link.

[0036] There may be multiple links from the above source configuration item to the target configuration item. The connectivity of the above source configuration item is determined by the reachability of the above links. If the source configuration item can reach the target configuration item through a certain link, the above link is a reachable link. If the source configuration item cannot reach the target configuration item through a certain link, the above link is an unreachable link. For example, the source configuration item is set to "cloud server host", the target configuration item is set to "physical subsystem", and there are 3 links from the source configuration item to the target configuration item. Then link 1 "cloud server host-virtual machine-container node-container Pod-container service-deployment unit-physical subsystem" is a reachable link, link 2 "cloud server host-virtual machine-deployment unit-physical subsystem" is a reachable link, and link 3 "cloud server host-operating system-deployment unit" is an unreachable link.

[0037] As an optional implementation, when the unreachable link exists in the multiple links of the source configuration item, the reachable nodes of the source configuration item are determined in the unreachable links; and the reachable node information in the unreachable links of the source configuration item is stored.

[0038] Specifically, a configuration item in the unreachable link that is connected to the source configuration item is determined as the reachable node.

[0039] For example, there is an unreachable link "cloud server host-operating system-deployment unit" in the link from the above "cloud server host" to the "physical subsystem". Then the "operating system" and "deployment unit" are configuration items connected to the source configuration item "cloud server host", that is, they are reachable nodes of the source configuration item "cloud server host", and the node information of the above "operating system" and "deployment unit" is stored.

[0040] As an optional implementation manner, when multiple links of the source configuration item are all the unreachable links, the source configuration item is determined as an isolated node.

[0041] For example, the source configuration item is set to "cloud server host" and the target configuration item is set to "physical subsystem". All links from "cloud server host" to "physical subsystem" are unreachable links, and there are no reachable nodes in the above unreachable links, that is, there are no nodes in the above links that are connected to the "cloud server host", and the above "cloud server host" is an isolated node.

[0042] Figure 3 is a module diagram according to an embodiment of the present invention, such as Figure 3 As shown, this module contains the following:

[0043] Configuration item entity relationship building module: Configuration items are operation and maintenance objects that need to be included in the scope of configuration management to support the operation and maintenance of the bank's production and disaster recovery systems. The scope of configuration items includes IT infrastructure (such as cabinets, servers, network equipment, storage devices, operating systems), cloud products (such as cloud servers, cloud storage, cloud databases), and other objects that need to be managed in operation and maintenance, such as physical subsystems. This module uses configuration item entity data and configuration item relationship models to build an operation and maintenance knowledge graph.

[0044] Configuration item entity filter: This module reads the specific verification rules for each configuration item in the configuration item break verification rule library, that is, filters the entity range that meets the rules for each configuration item and generates a set of entities to be verified.

[0045] Configuration item broken link analysis controller: This module controls reachable node analysis activities based on the existing configuration item relationship link model. The first layer traverses and controls the connectivity analysis activities from all starting configuration item entities to the end configuration item entities. For example, the starting configuration item is "cloud server host" and the end configuration item is "physical subsystem". The second layer traverses and controls all possible (non-end) node reachable analysis activities for the starting configuration item entity whose end point is unreachable. This module ensures that every type of end point unreachable link for each configuration item entity is resolved and checked.

[0046] Configuration item link connectivity analyzer: Based on the starting configuration item, end configuration item, and link model information given by the controller, check the connectivity of the starting configuration item entity and the end configuration item entity. For example: the analysis shows that the cloud server host A is unreachable to any physical subsystem entity. For the configuration item entity whose end point is unreachable, analyze the specific nodes that the entity can reach through all known links. For example, for cloud server host A, the analysis result is that link 1 "cloud server host-virtual machine-container node" has 3 links that can reach node 3, link 2 "cloud server host-operating system" has 1 link that can reach node 2, and link 3: there is no reachable node.

[0047] Configuration item broken link data storage: This module stores all configuration item unreachable target entities parsed by the controller and analyzer modules and the reachable link node information in the link model.

[0048] Configuration item disconnection data statistics module: This module is based on the data statistics in the storage device and displays the verification indicators and detailed data of the configuration items, including the configuration item disconnection rate, the number of verification entities, the number of isolated entities, the details of the nodes reachable by the path, etc.

[0049] The logic flow of the embodiment of the present invention is as follows:

[0050] 1. The configuration item disconnection check filter filters the set of configuration item entities to be checked based on given rules.

[0051] 2. The configuration item disconnection analysis controller and the link connectivity analyzer check the configuration item entities based on the given starting configuration item entity set (the configuration item entity set to be checked) and the connectivity link set related to the starting configuration item and the end configuration item:

[0052] a) Obtain a set of configuration item entities that are reachable between the starting configuration item entity and the end configuration item entity through a link connectivity analyzer.

[0053] b) The unreachable target configuration item entity set is obtained by subtracting the reachable configuration item entity set from the configuration item entity set.

[0054] c) The unreachable configuration item entity set is fragmented, and the fragmented unreachable configuration item subsets are iteratively processed. The reachable node information of the unreachable configuration item entity in the connectivity link set is obtained by checking with a link connectivity analyzer.

[0055] Timeout exception compensation process:

[0056] Since the size of the link reachability information of the unreachable configuration item entity is uncertain, the library may time out during the analysis process due to excessive data volume and long analysis time. The following steps are required to compensate for the exception:

[0057] 1) Timeout exception capture

[0058] 2) Split the unreachable configuration item entity shard set into half again and continue to perform the steps after 2-c above

[0059] 3) If a timeout occurs, repeat the above steps iteratively until success.

[0060] 3. The configuration item disconnection storage stores the unreachable target configuration item entity and its reachable node information in the connectivity link set.

[0061] 4. The configuration item broken link data statistics module counts and displays the verification indicators and detailed data of the configuration items.

[0062] Optionally, the executor of the above steps may be a background processor, or other devices with similar processing capabilities, or a machine that integrates at least an image acquisition device and a data processing device, wherein the image acquisition device may include a graphics acquisition module such as a camera, and the data processing device may include a computer, a mobile phone or other terminal, but is not limited thereto.

[0063] Through the above steps, the problem that the relationship between configuration items cannot be verified in the related technology is solved, and the verification efficiency of relationship data is improved.

[0064] The configuration item entity link analysis controller and link connectivity analyzer in the embodiment of the present invention can complete the broken link analysis and verification for millions of configuration item entities and hundreds of millions of configuration item entity relationships within a dozen minutes, with excellent processing performance.

[0065] The embodiment of the present invention can implement global relationship broken link checking based on the operation and maintenance knowledge graph for any configuration item that the business party is concerned about (i.e., the above-mentioned target configuration item), which is not limited to the endpoint configuration item in the physical sense and has high flexibility.
