Error message retry method, device, electronic device and storage medium

Technical Field

The present invention relates to the field of error message retry, and in particular to an error message retry method, device, electronic equipment and storage medium.

Background technique

Kubernetes (K8S) CSI Sidecar Containers is a set of standard containers designed to simplify the development and deployment of CSI drivers on Kubernetes. These containers observe the common logic of the Kubernetes API, trigger appropriate actions for the CSI volume driver container, and update the Kubernetes API as needed.

When operating K8S resources in batches, if there is a failure due to backend network problems/insufficient storage resources/parameter errors, CSI Sidecar will send a retry request based on the exponential backoff algorithm. Even so, a large number of error messages that need to be resent will be generated. The continuous sending of a large number of error messages occupies a large amount of CPU resources of the computer device, increasing the burden on the computer device.

Summary of the invention

Detailed ways

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

Kubernetes CSI Sidecar Containers is a set of standard containers designed to simplify the development and deployment of CSI drivers on Kubernetes. These containers observe the common logic of the Kubernetes API, trigger appropriate actions for the CSI volume driver container, and update the Kubernetes API as needed.

CSI is the abbreviation of Container Storage Interface, which aims to establish a set of standard storage call interfaces between container orchestration engine CO (Container Orchestrator System) and storage provider SP (Storage Provider), thereby defining industry standards and enabling storage providers (SP) to develop a plug-in that complies with the CSI standard and enable it to work in multiple container orchestration (CO) systems.

CSI stipulates that CO interacts with plug-ins through RPC (RPC is Remote Procedure Call). Each SP must provide:

Node Plugin: A gRPC endpoint that provides CSI RPC interfaces that must be run on the node. These interfaces are generally used for functions related to mounting/unmounting volumes.

Controller Plugin: A gRPC endpoint that provides a CSI RPC interface that can run anywhere, generally used for creating/deleting volume-related functions.

The Kubernetes development team maintains the following Kubernetes CSI Sidecar Containers features, as shown in Table 1 below.

Table 1. Functions of Kubernetes CSI Sidecar Containers

Exemplarily, as shown in Figure 1, when the sidecar container actively calls the CSI interface through a gRPC request, the following functional actions are completed:

Create/delete/expand PVC;

Create/delete/rollback volumesnapshot;

Mount/unmount PVC.

When an error occurs in the underlying CSI, the sidecar will complete the subsequent retry actions by requeuing the request. In order to avoid retry storms after errors, an exponential backoff algorithm is used to solve the problem of retry storms. However, this will generate a large number of error messages that need to be resent. The continuous sending of a large number of error messages occupies a large amount of CPU resources of computer devices, increasing the burden on computer devices.

Therefore, an embodiment of the present application provides an error message retry method, which aims to solve the problem that the prior art causes the continuous sending of a large number of error messages, occupying a large amount of CPU resources of the computer device and increasing the burden on the computer device.

It should be noted that the method for retrying an error message provided in the embodiment of the present application, its execution subject can be a device for retrying an error message, and the device for retrying an error message can be implemented as part or all of a computer device through software, hardware, or a combination of software and hardware, wherein the computer device can be a server or a terminal, wherein the server in the embodiment of the present application can be a single server or a server cluster composed of multiple servers, and the terminal in the embodiment of the present application can be a smart phone, a personal computer, a tablet computer, a wearable device, and other intelligent hardware devices such as an intelligent robot. In the following method embodiments, the execution subject is an electronic device as an example for explanation.

In one embodiment of the present application, as shown in FIG. 2 , a method for retrying an error message is provided, and the method is described by taking the application of the method to an electronic device as an example, including the following steps:

S11. Obtain target error information corresponding to the target error message.

In an optional implementation of the present application, the electronic device may send a message to other devices, and after the message sending fails, obtain a target error message and obtain target error information corresponding to the target error message.

In another optional implementation of the present application, the electronic device can also receive target error information corresponding to a target error message sent by other devices, or receive target error information corresponding to a target error message input by a user. The embodiment of the present application does not specifically limit the specific method for the electronic device to obtain the target error information corresponding to the target error message.

S12. Analyze the target error information to determine the error source corresponding to the target error message.

The error source is used to characterize the device that returns the target error information.

Specifically, after the electronic device obtains the target error information corresponding to the target error message, the electronic device may read and parse the target error information to determine the error source corresponding to the target error message.

In an optional implementation manner of the present application, the target error information corresponding to the target error message may include the error source and error cause corresponding to the target error message, wherein the error source is used to characterize the device that returns the target error information.

For example, suppose that the electronic device sends a target error message to device D, which needs to pass through devices A, B, and C. After the electronic device sends the target error message to device A, the sending is successful, but when device A forwards the target error message to device B, the target error message fails to be sent. Therefore, device B returns the target error information corresponding to the target message information to device A, and device B returns the target error information corresponding to the target message information to the electronic device again. At this time, the error source included in the target error information is used to characterize the target error information returned by device B to the electronic device.

Exemplarily, it is assumed that the target error information includes the cause of the error and the source of the error. Exemplarily, the cause of the error may include network error, parameter error, insufficient resources, etc., and the source of the error may be a faulty storage resource A, gateway resource B, cluster C, etc. When the cause of the error and the source of the error are combined, the target error information can present the following effect: xxyyyy. For example: the target error information is 01000A, where 01 represents the source of the error, such as storage cluster A, gateway B, etc. This content is determined by the source of the error identified by the CSI itself. Because the CSI is directly connected to the backend storage, it can be clearly set from the CSI itself which source 01 represents. Just ensure that the same source is the same error code. And 000A represents the specific cause of the error, such as a network error, parameter error, etc. This content is configured by the user. Exemplarily, the process of error code calling and configuration can be shown in Figure 3 below. Specifically, SIDECAR sends a request to CIS, CIS forwards the request to the backend storage, the backend storage returns an error to CIS, and CIS queries the configmap based on the error and returns it to SIDECAR.

S13. According to the error source, determine other error messages having the same error source as the target error message.

Specifically, after determining the error source corresponding to the target error message, the electronic device can determine the storage space corresponding to the target error message according to the corresponding relationship between the error source and the storage space, and store the target error information corresponding to the target error message in the corresponding storage space. Then, other error messages with the same error source as the target error message are determined in the storage space.

Among them, the number of other error messages can be 1, 2 or more, and the electronic device does not specifically limit the number of other error messages.

S14. According to the relationship between the target error message and other error messages, the target error message is resent, and before the target error message is successfully sent, resending of other error messages is prohibited.

In an optional implementation of the present application, the electronic device can calculate the sending time corresponding to the target error message based on a preset method, and after determining the sending time corresponding to the target error message, resend the target error message at the sending time, and prohibit resending other error messages before the target error message is successfully sent.

The error message retry method provided by the embodiment of the present invention obtains the target error information corresponding to the target error message, and then parses the target error information to determine the error source corresponding to the target error message, thereby ensuring the accuracy of the error source corresponding to the determined target error message. According to the error source, other error messages with the same error source as the target error message corresponding to the target error message are determined, thereby ensuring the accuracy of other error messages with the same error source as the target error message corresponding to the determined target error message. According to the relationship between the target error message and other error messages, the target error message is resent, and resending of other error messages is prohibited before the target error message is successfully sent. The above method does not need to resend a large number of error messages. The continuous sending of a large number of error messages occupies a large amount of CPU resources of the computer device and increases the burden of the computer device. Therefore, the number of error messages that need to be resent is reduced, the CPU resources of the computer device occupied are reduced, and the burden of the computer device is alleviated.

In one embodiment of the present application, as shown in FIG4 , a method for retrying an error message is provided, which is described by taking the method applied to an electronic device as an example, and includes the following steps:

S21. Obtain target error information corresponding to the target error message.

S22. Analyze the target error information to determine the error source corresponding to the target error message.

For this step, please refer to the introduction of S12 in FIG. 2 , which will not be described in detail here.

S23. Determine, according to the error source, other error messages having the same error source as that corresponding to the target error message.

For this step, please refer to the introduction of S13 in FIG. 2 , which will not be described in detail here.

S24. According to the relationship between the target error message and other error messages, the target error message is resent, and before the target error message is successfully sent, resending of other error messages is prohibited.

In an optional implementation manner of the present application, the above S24 "retransmitting the target error message according to the relationship between the target error message and other error messages, and prohibiting retransmitting other error messages before the target error message is successfully sent" may include the following steps:

S241. Analyze the target error information and determine the target waiting time corresponding to the target error message.

In an optional implementation of the present application, after the electronic device obtains the target error information corresponding to the target error message, the electronic device may read and parse the target error information to determine the target waiting time corresponding to the target error message.

In another optional implementation of the present application, the electronic device may also compare the target error information with the error information in a preset error information table, and determine the target waiting time corresponding to the target error message according to the comparison result.

The preset error information table may include error information corresponding to each error message and a waiting time corresponding to the error message.

S242. Obtain other waiting times corresponding to other error messages.

In an optional implementation of the present application, the electronic device may receive other waiting times corresponding to other error messages sent by other devices, or receive other waiting times corresponding to other error messages input by the user.

In another optional implementation of the present application, the electronic device can obtain other error information corresponding to other error messages, and compare the other error information with the error information in a preset error information table, and determine other waiting times corresponding to other error messages based on the comparison results.

The preset error information table may include error information corresponding to each error message and a waiting time corresponding to the error message.

S243. Determine a candidate retry time corresponding to the target error message according to the relationship between the target waiting time and other waiting times.

In an optional implementation of the present application, after the electronic device obtains the target waiting time corresponding to the target error message and other waiting times corresponding to other error messages, the electronic device can compare the target waiting time with the other waiting times, and determine the maximum time from the target waiting time and the other waiting times as the candidate retry time corresponding to the target error message.

In another optional implementation of the present application, the above S243 "determining the candidate retry time corresponding to the target error message according to the relationship between the target waiting time and other waiting times" may include the following steps:

(1) Analyze the target error information to determine the first weight information corresponding to the target error message.

In an optional implementation of the present application, the electronic device may also compare the target error information with the error information in a preset error information table, and determine the first weight information corresponding to the target error message according to the comparison result.

The preset error information table may include error information corresponding to each error message and weight information corresponding to the error message.

In another optional implementation of the present application, the electronic device may also receive first weight information corresponding to a target error message sent by other devices, or receive first weight information corresponding to a target error message input by a user.

(2) Obtain the second weight information corresponding to other error messages.

In an optional implementation of the present application, the electronic device may also receive second weight information corresponding to other error messages sent by other devices, or receive second weight information corresponding to other error messages input by a user.

The preset error information table may include error information corresponding to each error message and weight information corresponding to the error message.

(3) Based on the relationship between the first weight information, the second weight information, the target waiting time and other waiting times, determine the candidate retry time corresponding to the target error message.

In an optional implementation of the present application, the electronic device may add the product of the first weight information multiplied by the target waiting time and the product of the second weight information multiplied by other waiting times to obtain a candidate retry time corresponding to the target error message.

In another optional implementation of the present application, the above step (3) "determining the candidate retry time corresponding to the target error message based on the relationship between the first weight information, the second weight information, the target waiting time and other waiting times" may include the following steps:

(31) Dividing the first weight information by the sum of the first weight information and the second weight information to obtain target weight information corresponding to the target error message;

(32) Dividing the second weight information by the sum of the first weight information and the second weight information to obtain other weight information corresponding to other error messages;

(33) The product of the target weight information multiplied by the target waiting time is added to the product of other weight information multiplied by other waiting times to calculate the candidate retry time corresponding to the target error message.

Specifically, the electronic device can divide the first weight information by the sum of the first weight information and the second weight information to obtain the target weight information corresponding to the target error message, and divide the second weight information by the sum of the first weight information and the second weight information to obtain other weight information corresponding to other error messages. Then, the electronic device multiplies the product of the target weight information and the target waiting time by adding the product of the other weight information and the other waiting time to calculate the candidate retry time corresponding to the target error message.

S244. Resend the target error message according to the candidate retry time.

In an optional implementation of the present application, after the electronic device determines the candidate retry time corresponding to the target error message, the electronic device may resend the target error message after the retry time.

In another optional implementation manner of the present application, the above S244 “re-sending the target error message according to the candidate retry time” may include the following steps:

(1) Obtain the number of times the target error message is sent.

Specifically, after the electronic device determines the candidate retry time corresponding to the target error message, the electronic device may obtain the number of times the target error message is sent according to the record of the number of times the target error message is sent.

(2) Using the exponential backoff algorithm, based on the number of times the target error message is sent, the candidate waiting time corresponding to the target error message is calculated.

Specifically, after obtaining the number of transmissions corresponding to the target error message, the electronic device may calculate the candidate waiting time corresponding to the target error message based on the number of transmissions corresponding to the target error message using an exponential backoff algorithm.

Among them, the backoff algorithm is that after the nodes on the network send data conflicts, they wait for a certain time before sending again. The waiting time increases exponentially, so as to avoid frequent triggering conflicts. In computer networks, binary exponential backoff algorithm or truncated exponential backoff algorithm is often used as a part of the retransmission strategy of the same data block to avoid network congestion. After n conflicts occur, the waiting time is randomly selected between 0 and 2^n-1 slot times. For example, after the first conflict, each sender will wait for 0 or 1 slot times; after the second conflict, the waiting time of each sender will be arbitrarily selected between 0 and 3 slot times; after the third conflict, the waiting time of each sender will be arbitrarily selected between 0 and 7 slot times, and so on. As the number of conflicts increases, the waiting time of the sender will have the possibility of doubling. And the meaning of "truncated" is that after a certain number of times, the exponential operation will stop, that is, the waiting time will no longer increase indefinitely. For example, if the upper limit n is set to 10, the maximum waiting time is 1023 slot times. Because conflicts may occur in some scenarios during the waiting time, the general process will terminate after 16 retries. The specific backoff algorithm is as follows:

Determine the basic backoff time, which is the contention period (the one-way end-to-end propagation delay on the bus is x, and the end-to-end round-trip time of Ethernet is 2x). Ethernet sets the contention period to 51.2us. For 10Mb/s Ethernet, 512 bits, or 64 bytes, can be sent during the contention period. It can also be said that the contention period is 512 bit times. 1 bit time is the time required to send 1 bit. Therefore, this time unit is closely related to the data rate.

Randomly pick a number from the discrete integer set [0,1,…,] and record it as r. The time that retransmission should be postponed is r times the contention period. The above parameter k is calculated according to the following formula: k = Min [number of retransmissions, 10] It can be seen that when the number of retransmissions does not exceed 10, the parameter k is equal to the number of retransmissions; but when the number of retransmissions exceeds 10, k will no longer increase and will always be equal to 10.

When retransmission fails after 16 times (this indicates that there are too many stations that intend to send data at the same time, resulting in continuous collisions), the data is discarded and reported to the upper layer. For example, in the first retransmission, k = 1, and the random number r selects a number from the integers {0,1}. Therefore, the time for retransmission to be delayed is 0 or the contention period, and one of these two times is randomly selected. If a collision occurs again, k = 2 in the retransmission, and the random number r selects a number from the integers {0,1,2,3}. Therefore, the time for retransmission to be delayed is randomly selected from the four times of 0, 2x, 4x and 6x. Similarly, if a collision occurs, k = 3 in the retransmission, and the random number r selects a number from the integers {0,1,2,3,4,5,6,7}. And so on. If conflicts occur repeatedly, it means that there may be more stations participating in the contention channel. However, the use of the backoff algorithm can increase the average time required for retransmission to be delayed with the number of retransmissions (this is also called dynamic backoff), thereby reducing the probability of collisions and facilitating the stability of the entire system.

(3) Compare the candidate retry time with the candidate waiting time, and determine the maximum value from the candidate retry time and the candidate waiting time, which is the target retry time corresponding to the target error message.

Specifically, after calculating the candidate waiting time corresponding to the target error message, the electronic device can compare the candidate retry time with the candidate waiting time, determine the maximum value from the candidate retry time and the candidate waiting time, and use it as the target retry time corresponding to the target error message.

(4) After the target retry time, the target error message is resent.

Specifically, after determining the target retry time corresponding to the target error message, the electronic device may resend the target error message after the target retry time.

In an optional implementation manner of the present application, the above method may further include the following steps:

(5) After the target error message fails to be resent, the candidate retry time corresponding to the target error message is calculated again.

(6) Using the exponential backoff algorithm, based on the number of times the target error message is sent, the candidate waiting time corresponding to the target error message is calculated.

(7) Compare the candidate retry time corresponding to the target error message with the candidate waiting time corresponding to the target error message, and determine the maximum value from the candidate retry time and the candidate waiting time, which is the target retry time corresponding to the target error message;

(8) After the target retry time, the target error message is resent.

Specifically, when the target error message is sent for the first time after the target retry time, and the target error message fails to be sent, the electronic device needs to calculate the candidate retry time corresponding to the target error message again, and use the exponential backoff algorithm to calculate the candidate waiting time corresponding to the target error message based on the number of times the target error message is sent. Then, the electronic device compares the candidate retry time corresponding to the target error message with the candidate waiting time corresponding to the target error message, and determines the maximum value from the candidate retry time and the candidate waiting time, which is the target retry time corresponding to the target error message. After the target retry time, the target error message is resent. Among them, the way in which the electronic device calculates the candidate retry time and the candidate waiting time corresponding to the target error message can be found above, and will not be repeated again.

The error message retry method provided by the embodiment of the present invention parses the target error information, determines the target waiting time corresponding to the target error message, and ensures the accuracy of the target waiting time corresponding to the target error message. Then, the target error information is parsed to determine the first weight information corresponding to the target error message, and the accuracy of the first weight information corresponding to the determined target error message is ensured. The second weight information corresponding to other error messages is obtained. Then, the first weight information is divided by the sum of the first weight information and the second weight information to obtain the target weight information corresponding to the target error message, and the accuracy of the target weight information corresponding to the obtained target error message is ensured. The second weight information is divided by the sum of the first weight information and the second weight information to obtain other weight information corresponding to other error messages, and the accuracy of the other weight information corresponding to the calculated other error messages is ensured. The product of the target weight information multiplied by the target waiting time is added to the product of the other weight information multiplied by the other waiting time, and the candidate retry time corresponding to the target error message is calculated, and the accuracy of the calculated candidate retry time is ensured. After calculating the candidate retry time corresponding to the target error message, the electronic device obtains the number of transmissions corresponding to the target error message, and uses the exponential backoff algorithm to calculate the candidate waiting time corresponding to the target error message based on the number of transmissions corresponding to the target error message, thereby ensuring the accuracy of the candidate waiting time corresponding to the calculated target error message. The candidate retry time is compared with the candidate waiting time, and the maximum value is determined from the candidate retry time and the candidate waiting time, which is the target retry time corresponding to the target error message, thereby ensuring the accuracy of the target retry time corresponding to the determined target error message. Then, after the target retry time, the target error message is resent, thereby ensuring that the time interval for sending the target error message is neither too long nor too short, thereby reducing the number of error messages that need to be resent, reducing the CPU resources occupied by the computer device, and alleviating the burden on the computer device.

In addition, after the target error message fails to be resent, the candidate retry time corresponding to the target error message is calculated again, ensuring the accuracy of the calculated candidate retry time. Then, the exponential backoff algorithm calculates the candidate waiting time corresponding to the target error message based on the number of times the target error message is sent, ensuring the accuracy of the calculated candidate waiting time corresponding to the target error message. The candidate retry time corresponding to the target error message is compared with the candidate waiting time corresponding to the target error message, and the maximum value is determined from the candidate retry time and the candidate waiting time, which is the target retry time corresponding to the target error message, ensuring the accuracy of the determined target retry time corresponding to the target error message. After the target retry time, the target error message is resent, thereby ensuring that the target error message can be sent multiple times, and ensuring that the time interval for sending the target error message is not too long or too short, thereby reducing the number of error messages that need to be resent and reducing the burden on computer equipment.

In one embodiment of the present application, as shown in FIG5 , a method for retrying an error message is provided, and the method is described by taking the application of the method to an electronic device as an example, including the following steps:

S31. Obtain target error information corresponding to the target error message.

For the description of this step, please refer to the description of S21 in FIG. 4 , which will not be described in detail here.

S32: Analyze the target error information to determine the error source corresponding to the target error message.

For this step, please refer to the introduction of S22 in FIG. 4 , which will not be described in detail here.

S33. According to the error source, determine other error messages having the same error source as the target error message.

For the description of this step, please refer to the description of S23 in FIG. 4 , which will not be described in detail here.

S34. According to the relationship between the target error message and other error messages, the target error message is resent, and before the target error message is successfully sent, resending of other error messages is prohibited.

For the description of this step, please refer to the description of S24 in FIG. 4 , which will not be described in detail here.

S35. Obtain other error information corresponding to other error messages.

In an optional implementation of the present application, the electronic device may receive other error information corresponding to other error messages sent by other devices, or receive other error information corresponding to other error messages sent by other devices.

In another optional implementation of the present application, the electronic device may also obtain other error information corresponding to other error messages based on the result of recording the error message.

S36. Store other error information and target error information in the same storage space.

Specifically, after determining the target error information corresponding to the target error message and other error information corresponding to other error messages, the electronic device may store the other error information and the target error information in the same storage space.

Exemplarily, the electronic device may put other error information and target error information into different error pools. The error causes in different pools may be the same because their error sources are different. Exemplarily, as shown in FIG6 , the electronic device is classified according to the error source corresponding to the error message, into error source 1, error source 2, and error source 3, wherein error source 1 may include target error information and other error information belonging to error source 1. Among them, the error sources corresponding to the target error information and other error information are the same, but the error causes may be the same or different.

S37. After the target error message is sent successfully, other error information is deleted from the storage space, and other error messages are resent.

Specifically, after the electronic device successfully sends the target error message, the electronic device determines that the error source problem corresponding to the target error message has been resolved. Therefore, the electronic device can delete other error information from the storage space and resend other error messages.

The error message retry method provided in the embodiment of the present invention obtains other error information corresponding to other error messages; stores other error information and target error information in the same storage space, which can ensure that the electronic device can update and record the target error message and other error messages. After the target error message is successfully sent, the electronic device determines that the communication link from the electronic device to the error source device corresponding to the target error message is normal. The electronic device does not need to record the target error message and other error messages, so it deletes other error information from the storage space and resends other error messages, ensuring that the target error message and other error messages can be sent normally.
