Detailed Description
Fig. 1 is a flow chart of a method for determining feasibility of a change requirement according to an embodiment of the present application, where the method may be performed by a device for determining feasibility of a change requirement, and the device for determining feasibility of a change requirement may be a terminal device or a module for a terminal device, or a server or a module for a server. The subject matter of the implementation of the method is not limited in this application.
The method comprises the following steps:
Wherein the change requirement is used for indicating a change operation to the configuration.
In one possible implementation, the configuration may be some hardware device, such as a physical machine, a switch, a memory, or a hard disk. The configuration may also be some application, such as an application program, a background server, a cloud server, a database, or the like, and the specific content of the configuration is not limited in the application. The change requirement is used for indicating a change operation on the configuration, for example, the change requirement is to change the memory in the physical machine A; for another example, the change requirement is to migrate the cloud server a to the physical machine a; for another example, the change requirement is to delete service a.
The configuration item relation diagram comprises at least two configuration items and an association relation between the at least two configuration items.
In one possible implementation, the configuration item relationship graph is a directed graph, and the direction of the directed graph is used to indicate the association relationship between at least two configuration items. According to the scheme, the configuration item relation diagram is a directed diagram, the relation among the configuration items can be accurately reflected, the directed diagram is searched, the configuration item associated with the first configuration item can be rapidly and accurately determined, and then the result configuration item set can be rapidly and accurately determined.
In one possible implementation method, the association relationship between two configuration items may be a direct influence relationship, for example, the configuration item a is a physical machine, and the configuration item B is a container deployed in the physical machine a, so that the configuration item a and the configuration item B are direct influence relationships, that is, when the configuration item a cannot work normally, the configuration item B cannot work normally. The association relationship between two configuration items may be a transfer relationship, for example, configuration item a is a switch, configuration item B is a router, and configuration item a and configuration item B are connected together through a physical connection line, where configuration item a and configuration item B are transfer relationships. The association relationship between two configuration items may be a load balancing influence relationship, for example, configuration item a is a service, configuration item B is a server, and the server bears 20% of the traffic of configuration item a, and then configuration item a and configuration item B are load balancing influence relationships. The association relation between the two configuration items is not limited in the application.
In a possible implementation method, according to the names of the configuration items in the change requirement, determining a first configuration item corresponding to the change requirement in the configuration item relation diagram, for example, changing the memory in the physical machine a by the change requirement, if the configuration item name in the change requirement is the physical machine a, searching the configuration item with the same name as the physical machine a in the configuration item relation diagram as the first configuration item. If the configuration item relation diagram has a plurality of configuration items with the same name as the physical machine a, the number of the first configuration items may be plural, and the number of the first configuration items is not limited in the application.
In another possible implementation method, according to the identifier of the configuration item in the change requirement, determining the first configuration item corresponding to the change requirement in the configuration item relation diagram, where the identifier of the configuration item in the change requirement is not limited.
The result configuration item set comprises a first configuration item, and the configuration items in the result configuration item set have an association relationship with the first configuration item.
In one possible implementation method, first, a sub-configuration item set associated with a first configuration item is determined by traversing a configuration item relation graph, where the sub-configuration item set includes at least one configuration item, and the at least one configuration item has an association relation with the first configuration item. Then, a result configuration item set is determined according to the first configuration item and the sub configuration item set.
In one possible implementation, for each of a set of sub-configuration items, determining a level difference between a level of each sub-configuration item and a first level; if the sum of the layer level difference and the first layer level is smaller than a preset threshold value, determining that each sub-configuration item is included in the result configuration item set; wherein the first hierarchy is the hierarchy of the previous configuration item associated with each child configuration item in the configuration item relationship graph. The preset threshold may be the highest level to which the configuration item belongs in the configuration item relation diagram, or may be a numerical value not greater than the highest level, and the specific numerical value of the preset threshold is not limited in the application. According to the scheme, the sum of the limiting layer level difference and the first layer level is smaller than the preset threshold, so that the depth of traversing the configuration item relation diagram can be effectively reduced, and the result configuration item set can be rapidly and accurately determined.
In one possible implementation method, the feasibility of the changing requirement is determined according to the changing requirement and the result configuration item set, and if the changing requirement is feasible, processing operation is performed on all configuration items in the result configuration item set according to the changing requirement and the result configuration item set. If the change requirement is not feasible, the change requirement is canceled or reformulated according to the result configuration item set. The change requirement is exemplified by changing the memory in the physical machine a, the result configuration item set is { physical machine a, application B, service a }, and according to the result configuration item set, it can be seen that changing the memory in the physical machine a affects the normal operation of the service a, and if the service a needs to keep normal operation in the last period, the memory in the physical machine a cannot be changed according to the change requirement.
According to the scheme, the configuration item relation diagram comprises at least two configuration items and the association relation between the at least two configuration items, the configuration items associated with the first configuration item can be determined according to the configuration item relation diagram, and a result configuration item set is formed; according to the result configuration item set and the change requirement, configuration items which are influenced by the change requirement can be accurately determined, and the feasibility of the change requirement can be accurately determined.
In one possible implementation method, the hierarchy to which the configuration item in the configuration item relationship graph belongs includes one or more of the following: an environment layer, a hardware layer, a logic layer, a service layer, a center layer, an application layer, or a business layer. The hierarchy may be as shown in fig. 2. The environment layer comprises a machine room or a power distribution cabinet and the like; the hardware layer comprises hardware devices such as a switch, a server, a physical machine or a magnetic disk and the like; the logic layer comprises a cloud platform, a container, a cluster or a virtual server and the like; the service layer comprises database service, encryption service, container service or signature service and the like; the application layer comprises a plurality of application systems; the central layer is mainly used for indicating the region where the server for deploying the application system is located; the service layer mainly refers to the type of service provided externally. According to the scheme, the configuration items are hierarchically divided, so that the types of the configuration items and the association relation among the configuration items can be accurately determined.
In one possible implementation, a configuration item relationship diagram is shown in fig. 3. In fig. 3, the machine room is located at an environment layer, and the physical machine a, the physical machine B, the physical machine C, and the switch a belong to a hardware layer, where the relationships between the physical machine a, the physical machine B, the physical machine C, and the switch a and the machine room are all transfer relationships. The physical machine A is provided with a container A and an application B, the relation between the container A and the application B and the physical machine A is a direct influence relation, the container A is provided with an application A, and the relation between the application A and the container A is a direct influence relation. The service A uses the service provided by the application A, and the relationship between the service A and the application A is a direct influence relationship. In a possible implementation method, taking the configuration item relation diagram shown in fig. 3 as an example, how the result configuration item set is determined according to the first configuration item and the configuration item relation diagram in step 103 is described. The changing requirement is to replace the memory in the physical machine a. Fig. 4 is a schematic flow chart of determining a result configuration item set according to an embodiment of the present application, where the method includes the following steps:
In one possible implementation method, the hierarchy to which the configuration items in the configuration item relationship graph belong includes 7 kinds of following: an environment layer, a hardware layer, a logic layer, a service layer, a center layer, an application layer and a service layer. The 7 levels are numbered 1-7, namely the level of the environment layer is 1, the level of the hardware layer is 2, the level of the logic layer is 3, the level of the service layer is 4, the level of the center layer is 5, the level of the application layer is 6, and the level of the service layer is 7.
In one possible implementation method, a configuration item relation diagram is searched according to a name of a configuration item in a change requirement, namely, a physical machine A, and the configuration item with the same name as the physical machine A in the configuration item relation diagram is determined to be a first configuration item, namely, the first configuration item is { physical machine A }.
In a possible implementation method, a breadth-first traversal algorithm is adopted to traverse the configuration item relation graph to determine a sub configuration item set associated with the first configuration item, other traversal algorithms can also be adopted to traverse the configuration item relation graph, and the algorithm for traversing the configuration item relation graph is not limited in the application. According to the illustration in fig. 3, the subset configuration item set obtained by traversing the physical machine a by using breadth-first traversal algorithm is { container a, application B }, and the container a belongs to a logical layer, so that the hierarchy to which the container a belongs is 3; similarly, application B belongs to the application layer, and the hierarchy to which application B belongs is 6.
In step 203, it is determined whether the sum of the level difference and the first level is smaller than a predetermined threshold.
In one possible implementation, the level difference refers to the absolute value of the difference between the level of each of the subset of configuration items and the first level. The first hierarchy refers to the hierarchy of the previous configuration item associated with each child configuration item in the configuration item relationship graph. Judging whether the sum of the fault level difference and the first level is smaller than a preset threshold value, wherein the preset threshold value can be the highest level to which the configuration items in the configuration item relation diagram belong. If the sum of the layer level difference and the first layer level is smaller than a preset threshold, traversing the sub-configuration item by using the sub-configuration item as a starting point and adopting a breadth-first traversing algorithm, determining a configuration item set associated with the sub-configuration item, and adding the configuration item set into the sub-configuration item set. If the sum of the layer level difference and the first layer level is greater than or equal to a preset threshold value, stopping traversing, and outputting the sub-configuration item set.
In step 202, the hierarchy to which the container a belongs is 3, the first hierarchy is the hierarchy to which the previous configuration item associated with the application a belongs, that is, the hierarchy to which the physical machine a belongs, that is, the first hierarchy is 2, the difference between the hierarchy to which the physical machine a belongs and the hierarchy to which the container a belongs is 1, the sum of the first hierarchy and the level difference is 3, and is smaller than a preset threshold, and the preset threshold is the highest hierarchy 7 to which the configuration item belongs, so that the container a is continuously traversed, the configuration item set associated with the container a is determined to be { application a }, the configuration item set is added to the subset configuration item set, and the obtained subset configuration item set is { container a, application B, application a }.
Similarly, the difference between the level to which the application B belongs and the level to which the physical machine a belongs is 4, and the sum of the level to which the physical machine a belongs and the level difference is 6, which is smaller than the preset threshold, so that the application B is continuously traversed, and no node exists in the application B, so that the application B is stopped from being traversed.
Then, judging the hierarchy to which the application A belongs, wherein the hierarchy to which the application A belongs is 6, the first hierarchy is the hierarchy to which the previous configuration item associated with the application A belongs, namely the hierarchy to which the container A belongs, namely the first hierarchy is 3, the hierarchy difference between the hierarchy to which the container A belongs and the hierarchy to which the application A belongs is 3, and the sum of the first hierarchy and the hierarchy difference is 6 and is smaller than a preset threshold value 7, so that traversing the application A is continued, determining the configuration item set associated with the application A as { service A }, adding the configuration item set into the sub configuration item set, and obtaining the sub configuration item set as { container A, application B, application A and service A }.
Then, the hierarchy to which the service a belongs is determined to be 7, the first hierarchy is the hierarchy to which the previous configuration item associated with the service a belongs, that is, the hierarchy to which the application a belongs, that is, the first hierarchy is 6, the difference between the hierarchy to which the service a belongs and the hierarchy to which the application a belongs is 1, and the sum of the first hierarchy and the difference is 8 and is greater than a preset threshold value of 7, so that the traversal is stopped, and the obtained sub-configuration item set is { container a, application B, application a, service a }.
In another possible implementation method, a size relationship between a hierarchy to which a child configuration item in the subset of configuration items belongs and the first hierarchy is determined. If the hierarchy to which the sub-configuration items in the sub-configuration item set belong is greater than or equal to the first hierarchy, traversing the sub-configuration items by using a breadth-first traversing algorithm with the sub-configuration items in the sub-configuration item set as a starting point, determining a configuration item set associated with the sub-configuration items, and adding the configuration item set into the sub-configuration item set. If the hierarchy to which the child configuration items in the child configuration item set belong is smaller than the first hierarchy, stopping traversing.
In one possible implementation, the result configuration item set is determined according to a union of the first configuration item and the sub configuration item set. The first configuration item in the step 201 is { physical machine a }, and the sub-configuration item sets in the steps 202 and 203 are { container a, application B, application a, service a }, so the result configuration item set is { physical machine a, container a, application B, application a, service a }.
