[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0062] The present application embodiment provides a method for restarting a device due to a fault, such as Figure 1 As shown, the specific steps include:

[0063] S101: Obtain the total number of machines in the cluster to which the alarm machine belongs and the maximum usage rate of each target resource of each machine.

[0064] The alarm machine refers to a machine that generates a fault alarm, such as a server, etc. When a machine generates a fault alarm, it automatically enters the restart processing decision, that is, executes the method provided by the embodiment of the present application.

[0065] To ensure high availability and load balancing, a service is usually provided by a cluster of multiple machines. Therefore, the cluster to which the alarm machine belongs is composed of multiple machines that share the same service with the alarm machine.

[0066] It should be noted that target resources are designated resources, typically those required and highly utilized by the alarming machine to provide the corresponding service, such as CPU resources and memory resources. By setting the number of machines in the cluster and the maximum utilization of the target resources for each machine, the remaining machines in the cluster can ensure the effective provision of target resources during a restart, thereby ensuring that the services provided by the alarming machine can be provided normally after the restart.

[0067] Specifically, the obtained maximum utilization rate of each target resource of each machine may be the maximum utilization rate of each target resource of the machine recorded on the current machine within a period of time.

[0068] Optionally, when the alarm machine does not belong to a cluster, it cannot be restarted directly, otherwise the services it provides will be stopped. Therefore, more complex operations such as service transfer are required, which often require manual operation. Therefore, when the alarm machine does not belong to a cluster, a prompt message can be issued to the user, prompting the user to perform manual intervention.

[0069] Optionally, in the embodiment of the present application, a specific implementation of step S101 is as follows: Figure 2 As shown, the following steps are included:

[0070] S201: Obtain the total number of machines in the cluster to which the alarm machine belongs, as well as the maximum CPU usage and the maximum memory usage of each machine.

[0071] In the embodiment of the present application, the target resources mainly include CPU resources and memory resources, and of course may also include other resources, not limited to CPU resources and memory resources.

[0072] S202: Determine whether there is a special resource indicator identifier in the information of the deployment unit corresponding to the alarm machine.

[0073] It should be noted that when the alarming machine belongs to a cluster, its cluster constitutes the corresponding deployment unit, and the deployment unit information includes multiple pieces of information about the cluster. Machines providing special services may rely on special resources, and in this case, the deployment unit information will store the identifier of the special resource. Therefore, it is necessary to first determine whether the special resource identifier exists in the deployment unit information corresponding to the alarming machine. If so, the resource corresponding to the special resource identifier should also be the target resource, so step S203 must be further executed.

[0074] S203: Obtain the highest resource usage rate corresponding to the special resource indicator identifier of each machine.

[0075] S102 : For each target resource, calculate the sum of the highest utilization rates of the target resources of each machine to obtain the total utilization rate corresponding to the target resource.

[0076] By calculating the sum of the maximum utilization rates of the target resources of each machine, we can obtain the highest total utilization rate of each target resource when the cluster provides services, and then restart the cluster while ensuring the total utilization rate.

[0077] S103 , performing a quotient operation on the total usage rate corresponding to each target resource and the target value to obtain an integer quotient corresponding to each target resource.

[0078] Among them, the target value is 1.

[0079] It should be noted that taking the quotient of the total utilization rate corresponding to the target resource and the target value refers to the integer quotient obtained by dividing the total utilization rate corresponding to the target resource by the target value, that is, the remainder is not considered, and it can also be considered as the digits before the decimal point of the calculation result.

[0080] Since a target resource for each machine is 100%, that is, 1, the target value is 1, so that the number of machines required to provide the total utilization corresponding to the target resource can be determined.

[0081] S104. Calculate the sum of the maximum value of the integer quotients corresponding to each target resource and the target value to obtain the required number of machines.

[0082] It should be noted that when providing services, it is obviously necessary to meet the demand for each target resource. When the target resource with the maximum demand is met, the demand for all target resources can definitely be guaranteed. Therefore, the maximum value is determined from the integer quotients corresponding to each target resource, and then the calculation is performed.

[0083] Specifically, the total utilization rate for each target resource is divided by 1 to obtain the number of machines required to meet the target resource's total utilization rate. Considering the possibility of a remainder, an additional 1 is added to ensure the target resource's demand. This yields the minimum number of machines required to meet the target resource's demand. This is the required number of machines.

[0084] S105 . Divide the ratio of the number of machines by the target value, and add the integer quotient thereof to the target value to obtain the number of groups.

[0085] The machine quantity ratio is equal to the quotient obtained by dividing the total quantity of each machine by the difference between the total quantity of each machine and the required quantity of machines.

[0086] It's important to note that, because the number of machines not yet restarted must be at least the required number of machines, the maximum number of machines restarted at a time—that is, the number of machines in a group—can only be the difference between the total number of machines and the required number of machines. Therefore, if the number is divisible evenly, that is, when the ratio of the number of machines is an integer, the number of groups is the quotient of the total number of machines divided by the difference between the total number of machines and the required number of machines. This is the integer quotient of the ratio of the number of machines divided by the target value. However, given that the number is not divisible evenly in most cases, an additional group is added, with the number of machines in the final group being less than the difference between the total number of machines and the required number of machines.

[0087] Of course, you can also first determine whether the ratio of the number of machines is an integer. If it is an integer, you do not need to add the target value. In this case, the number of machines in each group is the difference between the total number of machines and the required number of machines. If the remainder is not zero, add the target value.

[0088] S106: Group the machines according to the number of groups.

[0089] It should be noted that when grouping, it is not only necessary to divide each machine into groups of the required number, but also the number of machines in each group should not exceed the difference between the total number of each machine and the required number of machines to ensure.

[0090] Alternatively, assuming the number of groups is N, the number of machines in each of the N-1 groups can be the difference between the total number of machines and the required number of machines, and one group can be the remaining machines. Of course, grouping can also be done using strategies.

[0091] S107: Restart each machine in each group in turn.

[0092] Specifically, for each divided group, the machines in the group are restarted simultaneously.

[0093] The embodiment of the present application provides a method for restarting a device after a fault, by obtaining the total number of machines in the cluster to which the alarm machine belongs and the maximum utilization rate of each target resource of each machine, and calculating the sum of the maximum utilization rates of the target resources of each machine for each target resource, to obtain the total utilization rate corresponding to the target resource, then taking the quotient of the total utilization rate corresponding to each target resource and the target value, to obtain the integer quotient corresponding to each target resource, and summing the maximum value of the integer quotients corresponding to each target resource with the target value to obtain the required number of machines, thereby obtaining the machines required to provide the maximum target resource demand. Then, the ratio of the number of machines is divided by the integer quotient of the target value and added to the target value to obtain the number of groups. The ratio of the number of machines is equal to the quotient obtained by dividing the total number of machines by the difference between the total number of machines and the required number of machines, thereby obtaining the number of groups under the condition that the number of machines that have not been restarted is the required number of machines. Finally, the machines are grouped according to the number of groups, and each machine in each group is restarted in turn, so that the machines can be restarted under the premise of ensuring resource demand and not affecting the external business services of the cluster.

[0094] Another embodiment of the present application provides another method for restarting a device after a failure, such as Figure 3 As shown, the specific steps include:

[0095] S301: Match the deployment unit corresponding to the alarm machine and obtain information about the deployment unit corresponding to the alarm machine.

[0096] It should be noted that each machine corresponds to a deployment unit, and a deployment unit can correspond to multiple machines. That is, a deployment unit can be composed of one machine or multiple machines to achieve availability.

[0097] Therefore, in the embodiment of the present application, the deployment unit corresponding to the alarm machine is first matched to obtain the information of the deployment unit corresponding to the alarm machine to determine whether the alarm machine has a cluster to which it belongs and whether it is network-related.

[0098] S302: Determine whether the deployment unit is related to the network connection according to the network connection related tag in the information of the deployment unit.

[0099] It should be noted that China National Clearing Corporation (CNS) is a platform managed by an organization and connected to the clearing platforms of various banks. Therefore, deployment units related to CNS cannot be restarted at will. Manual intervention is required to avoid problems. Therefore, if it is necessary to determine whether the deployment unit is related to CNS, if so, step S303 is executed. If not, the subsequent steps can be continued, that is, step S304 is executed.

[0100] S303: Feedback target prompt information.

[0101] The target prompt information is used to prompt the user to perform manual intervention.

[0102] S304: Determine whether the deployment unit belongs to a cluster based on the cluster tag in the information of the deployment unit corresponding to the alarm machine.

[0103] It's important to note that if a deployment unit consisting of a single machine is directly restarted, the service it provides will be interrupted because there are no other machines to back it up. This often requires complex operations such as service migration, which requires manual intervention. Therefore, it's necessary to first determine whether the deployment unit belongs to a cluster, that is, whether the alarming machine exists in a cluster.

[0104] If it is determined that the deployment unit does not belong to a cluster, step S303 is executed to feedback target prompt information. If it is determined that the deployment unit belongs to a cluster, step S305 is executed.

[0105] S305: Obtain the total number of machines under the deployment unit corresponding to the alarm machine and the maximum usage rate of each target resource of each machine.

[0106] Among them, each machine in the cluster to which the alarm machine belongs constitutes the deployment unit corresponding to the alarm machine, so obtaining the total number of machines under the deployment unit corresponding to the alarm machine and the maximum utilization rate of each target resource of each machine is to obtain the total number of machines in the cluster to which the alarm machine belongs and the maximum utilization rate of each target resource of each machine.

[0107] It should be noted that, for a more specific implementation of step S305, reference may be made to step S101 in the above method embodiment, which will not be described in detail here.

[0109] It should be noted that the specific implementation of step S306 may refer to step S102 in the above method embodiment, and will not be repeated here.

[0110] S307 , performing a quotient operation on the total usage rate corresponding to each target resource and the target value to obtain an integer quotient corresponding to each target resource.

[0111] Among them, the target value is 1.

[0112] It should be noted that the specific implementation of step S307 may refer to step S103 in the above method embodiment, and will not be repeated here.

[0114] It should be noted that the specific implementation of step S308 may refer to step S104 in the above method embodiment, and will not be repeated here.

[0115] S309: Divide the ratio of the number of machines by the target value, and add the integer quotient to the target value to obtain the number of groups.

[0116] The machine quantity ratio is equal to the quotient obtained by dividing the total quantity of each machine by the difference between the total quantity of each machine and the required quantity of machines.

[0117] It should be noted that the specific implementation of step S309 may refer to step S105 in the above method embodiment, and will not be repeated here.

[0118] S310: Group the machines according to the number of groups.

[0119] It should be noted that the specific implementation of step S310 may refer to step S106 in the above method embodiment, and will not be repeated here.

[0120] S311. Restart each machine in each group in turn.

[0121] It should be noted that the specific implementation of step S311 may refer to step S107 in the above method embodiment, and will not be repeated here.
