Description

Technical Field

[0001] The present invention relates to the field of network communication technology, and in particular to a method, device, computer equipment and storage medium for locating a fault message. Background Art

[0002] With the rapid development of digitalization and intelligence, all businesses are increasingly evolving towards intelligence and precision. However, the prerequisite for intelligence and digitalization is the collection of large amounts of data. This process not only relies on increasingly powerful computing power, but also requires hardware and software support for high-speed and reliable data storage and retrieval. For example, Linux systems support the Serial Attached SCSI (SAS) protocol or SAS disks that support high-speed read and write operations.

[0003] Due to the complex and tedious nature of the underlying protocol interface, when a fault occurs during protocol message transmission based on the SAS protocol, the protocol message at the time of the fault is usually captured (with a high probability of missing the point at which the error occurred) and fed back to the back-end R&D personnel, who then use various methods to analyze, reproduce, and resolve the problem. This approach relies on strong professional capabilities and cannot accurately locate the business corresponding to the faulty message. This results in the need to repeatedly initiate a new round of capture, reproduction, location, and resolution before the problem is resolved, resulting in a long troubleshooting cycle, affecting the customer experience, and relatively high consumption costs. Summary of the Invention

[0004] In view of this, the present invention provides a method, apparatus, computer device and storage medium for locating a fault message to solve the problem of being unable to accurately locate the service corresponding to the fault message.

[0005] In a first aspect, the present invention provides a method for locating a fault message, the method comprising: in a case where the reply message is a response message generated for a SAS protocol message, receiving an index of the reply message sent from a collection device, the SAS protocol message being sent by the server to the hard disk when a service needs to be executed; based on the index of the reply message, obtaining the reply message, and determining the service number corresponding to the SAS protocol message in the shared memory of the server, the reply message carrying a status code; determining whether the SAS protocol message is a fault message based on the status code and a preset correspondence; if so, locating the service corresponding to the SAS protocol message based on the service number and the service mapping table in the shared memory, the service mapping table including multiple services and the service number corresponding to each service.

[0006] Based on the method provided in the first aspect above, when the reply message is a response message generated for a SAS protocol message, the index of the reply message sent from the collection device can be received, and based on the index of the reply message, the reply message can be obtained in the shared memory of the server, and the service number corresponding to the SAS protocol message can be determined. According to the status code and the preset correspondence, it is determined whether the SAS protocol message is a fault message; if so, the service corresponding to the SAS protocol message is located based on the service number and the service mapping table in the shared memory.

[0007] Since the reply message is a response message generated for the SAS protocol message, the reply message can be obtained in the shared memory of the server according to the index of the reply message, and the business number corresponding to the SAS protocol message associated with the index of the reply message can be determined. This shared memory method can reduce data copying between devices and improve efficiency.

[0008] In addition, based on the status code of the response message and the preset correspondence, it can be determined whether the SAS protocol message corresponding to the response message is a fault message. When it is determined to be a fault message, the service code is determined based on the one-to-one correspondence between the service number and the service mapping table in the shared memory, and the service corresponding to the faulty SAS protocol message is accurately located. This achieves the identification of the service corresponding to the fault message with a single confirmation, avoiding the time-consuming multiple identifications. This method improves the customer experience, shortens the time to locate the service corresponding to the fault message, and thus reduces the location cost.

[0009] In an optional embodiment, based on the index of the reply message, the reply message is obtained in the shared memory of the server, and the business number corresponding to the SAS protocol message is determined, including: based on the index of the reply message, the reply message is obtained in the shared memory of the server; among multiple descriptors in the shared memory, the target descriptor including the index of the reply message is screened, the target descriptor is a shared descriptor corresponding to the SAS protocol message and the reply message, and the target descriptor includes the business number corresponding to the SAS protocol message.

[0010] Based on the above method, based on the index of the response message, the target descriptor including the index of the response message can be determined in the shared memory, and then the service number corresponding to the SAS protocol message can be accurately determined, which facilitates the subsequent determination of the service corresponding to the SAS protocol message based on the service number.

[0011] In an optional embodiment, the method further includes: determining the fault cause of the SAS protocol message based on the status code and the status code conversion table; storing the fault cause in a shared memory, and deleting the target descriptor, the SAS protocol message, and the response message from the shared memory.

[0012] Based on the above method, the fault cause of the faulty SAS protocol message can be accurately determined based on the status code and the status code conversion table, so as to solve the problem corresponding to the SAS protocol message fault based on the fault cause.

[0013] In a second aspect, the present invention provides a method for locating a fault message, which is applied to a collection device, the method comprising: obtaining a SAS protocol message and an index of the SAS protocol message sent by a server to a hard disk, wherein the SAS protocol message includes a SAS protocol message identifier; receiving a response message sent from the hard disk, and determining whether the response message is a response message generated for the SAS protocol message based on the SAS protocol message identifier and the response message identifier, wherein the response message includes the response message identifier;

[0014] If so, the index of the reply message is sent to the analysis device, which is used to locate the service number corresponding to the SAS protocol message in the shared memory of the server and obtain the reply message based on the index of the reply message, and determine whether the SAS protocol message is a fault message and locate the service corresponding to the SAS protocol message based on the service number and the reply message.

[0015] Based on the method provided in the second aspect above, the SAS protocol message sent by the server to the hard disk and the index of the SAS protocol message can be obtained; a response message sent from the hard disk is received, and based on the SAS protocol message identifier and the response message identifier, it is determined whether the response message is a response message generated for the SAS protocol message; if so, the index of the response message is sent to the analysis device, and the analysis device is used to locate the service number corresponding to the SAS protocol message in the shared memory of the server based on the index of the response message and obtain the response message, and determine whether the SAS protocol message is a fault message and locate the service corresponding to the SAS protocol message based on the service number and the response message.

[0016] Since it is possible to determine whether the reply message is a response message generated for the SAS protocol message based on the SAS protocol message identifier and the reply message identifier, that is, first determine whether the reply message matches the SAS protocol message. If it matches, the index of the reply message is sent to the analysis device, so that the analysis device can determine whether the SAS protocol message is a fault message and locate the business corresponding to the SAS protocol message, avoiding the problem of long fault resolution cycle caused by multiple fault message locating corresponding businesses, improving customer experience, and reducing the cost of locating fault messages.

[0017] In an optional implementation, the shared memory includes a protocol area, and the protocol area is used to store messages. The method further includes: copying the SAS protocol message to a corresponding position in the protocol area according to an index of the SAS protocol message.

[0018] Based on the above method, the SAS protocol message can be stored in the corresponding position of the protocol area, which is convenient for subsequent acquisition of the SAS protocol message and parsing it to obtain the corresponding message.

[0019] In an optional embodiment, the shared memory also includes a configuration area, receives a reply message sent from the hard disk, and determines whether the reply message is a response message generated for the SAS protocol message based on the SAS protocol message identifier and the reply message identifier, including: obtaining the business number corresponding to the SAS protocol message; allocating a first descriptor to the SAS protocol message in the configuration area, the first descriptor including the SAS protocol message identifier, the index of the SAS protocol message and the business number corresponding to the SAS protocol message; receiving the reply message sent from the hard disk, and copying the reply message to the corresponding position of the protocol area based on the index of the reply message; and searching in the configuration area based on the reply message identifier to see whether the SAS protocol message identifier included in the descriptor is consistent with the reply message identifier.

[0020] If so, it is determined that the reply message is a response message generated for the SAS protocol message, the reply message identifier and the reply message index are stored in the first descriptor, and the target descriptor corresponding to the SAS protocol message and the reply message is obtained.

[0021] Based on the above method, a search can be performed in the configuration area based on the response message identifier to determine whether the SAS protocol message identifier included in the descriptor is consistent with the response message identifier, thereby determining whether the response message is a response message generated in response to the SAS protocol message. If the response message is a response message generated in response to the SAS protocol message, the first descriptor is updated to obtain a target descriptor, so that the response message identifier in the target descriptor can be subsequently sent to the analysis device.

[0022] In a third aspect, the present invention provides an analysis device, which includes: a transceiver module for receiving an index of a response message sent from a collection device when the response message is a response message generated for a SAS protocol message, the SAS protocol message being sent by the server to the hard disk; a processing module for obtaining the response message in the shared memory of the server based on the index of the response message, and determining the service number corresponding to the SAS protocol message, the response message carrying a status code; the processing module is also used to determine whether the SAS protocol message is a fault message based on the status code and a preset correspondence; the processing module is also used to locate the service corresponding to the SAS protocol message based on the service number and the service mapping table in the shared memory if so, the service mapping table including multiple services and the service number corresponding to each service.

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying 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 making creative efforts shall fall within the scope of protection of the present invention.

[0037] As described in the background technology, during the protocol message transmission process based on the SAS protocol, once a fault occurs, multiple cycles of message capture, reproduction, location, and resolution are required to locate the business corresponding to the faulty message. This results in a long fault resolution cycle, affects customer experience, and consumes relatively high costs.

[0038] In order to solve the above problems, an embodiment of the present invention provides a method for locating a fault message, which is applied to an analysis device. The method includes receiving an index of a response message sent from a collection device when the response message is a response message generated for a SAS protocol message, and the SAS protocol message is sent by the server to the hard disk; based on the index of the response message, obtaining the response message in the shared memory of the server, and determining the business number corresponding to the SAS protocol message, and the response message carries a status code; determining whether the SAS protocol message is a fault message based on the status code and the preset correspondence; if so, locating the business corresponding to the SAS protocol message based on the business number and the business mapping table in the shared memory, the business mapping table includes multiple businesses and the business number corresponding to each business. This method can accurately locate the business corresponding to the fault message, shorten the cycle of resolving the fault message, improve customer experience, and reduce costs.

[0039] like Figure 1 As shown, Figure 1FIG. 1 is a schematic diagram of the architecture of a fault message locating system 10 according to an embodiment of the present invention. Figure 1 In the present invention, the fault message positioning system 10 may include an analysis device 101, a collection device 102, a server 103, a shared memory 104 and a hard disk 105. Figure 1 In the shared memory, storage services can be provided for analysis devices, collection devices, and servers.

[0040] The analysis device in the embodiments of the present application, for example, analysis device 101, can be any device with computing and communication functions. The analysis device may include a receiving module, a display module, and an analysis module. The receiving module is configured to receive information from the collection device. The display module is configured to display alarm information or fault causes processed by the analysis module. The analysis module is configured to locate the service corresponding to the fault message and analyze the fault cause of the fault message.

[0041] The collecting device in the embodiment of the present application, for example, the collecting device 102, is a device with wireless transceiver function, and is used to collect protocol messages or other information from points that need to be collected, such as the kernel layer, kernel driver layer, and application layer.

[0042] The server in the embodiment of the present application, such as server 103, is a device with computing and communication functions, including but not limited to cloud servers, tower servers, etc.

[0043] The shared memory in the embodiment of the present application, for example, shared memory 104, is a relatively large continuous physical address that is separately allocated and mapped when the server kernel starts. The shared memory is functionally divided into a configuration area and a message protocol area (also called a protocol area). The configuration area and the message protocol area are allocated in a default ratio of 1:9 based on the total byte size of the shared memory. It is understandable that the ratio can be set according to actual needs without limitation. Figure 2 As shown, Figure 2 Schematic diagram of a shared memory according to an embodiment of the present invention; the configuration area is used to store service mapping tables and descriptors, and the message protocol area is used to store multiple messages.

[0044] For the configuration area, the server reads the configuration file and maintains a global service mapping table in the configuration area. All services must be reflected in this service mapping table. It is understandable that the level of detail in the mapping table determines the specific service level that can be achieved during error location. The server calculates the maximum number of descriptors that the configuration area can support based on the allocated message protocol area size. When the descriptors are filled, they are repeatedly saved by re-overwriting the header. The configuration area includes a dedicated descriptor to record the repeatedly saved descriptors.

[0045] For the message protocol area, the message protocol area stores paired protocol messages (SAS protocol messages and response messages). Similarly, after the protocol message area is fully filled, the server repetitively saves the message by re-covering the header.

[0046] For the shared memory, the server starts a periodic timer to check whether the message saved in the message protocol area is within the validity period. If not, a message is sent to the analysis device.

[0047] The hard disk in the embodiment of the present application, for example, the hard disk 105, is any hard disk with a storage function, including but not limited to a mechanical hard disk, a solid-state hard disk, a hybrid hard disk, and the like.

[0048] Figure 1 The fault message locating system 10 shown is for illustrative purposes only and is not intended to limit the technical solutions of the present application. Those skilled in the art will appreciate that, in a specific implementation, the fault message locating system 10 may also include other devices, and the number of hard disks may also be determined based on specific needs, without limitation.

[0049] According to an embodiment of the present invention, an embodiment of a method for locating a fault message is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0050] In this embodiment, a method for locating a fault message is provided, which can be used in the above-mentioned collection device. Figure 3 FIG. 1 is a flow chart of a method for locating a fault message according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0051] S301: Acquire a SAS protocol message and an index of the SAS protocol message sent by a server to a hard disk.

[0052] The SAS protocol message is a message for data transmission based on the SAS protocol. The SAS protocol message includes a SAS protocol message identifier. For example, the SAS protocol message identifier is a protocol sequence number identifier SEQID.

[0053] In the embodiment of the present invention, the index of the SAS protocol message is the storage address of the SAS protocol message in the protocol area in the shared memory.

[0054] As you can understand, SAS protocol messages are sent by the server to the hard drive when a service needs to be executed. After receiving the SAS protocol message, the hard drive will return a response message and, based on the received SAS protocol message, obtain the service information that the hard drive needs to execute and execute the service corresponding to the SAS protocol message.

[0055] In one example, when a server sends a SAS protocol message to a hard disk, a collection device obtains the SAS protocol message sent by the server to the hard disk, allocates a first descriptor to the SAS protocol message in a configuration area, and obtains an index of the SAS protocol message.

[0056] It can be understood that when the server sends multiple SAS protocol messages to the hard disk, the collection device obtains the multiple SAS protocol messages sent by the server to the hard disk, and allocates multiple descriptors to the SAS protocol messages in the configuration area in a forward-to-backward order to obtain indexes of the multiple SAS protocol messages.

[0057] S302: Receive a response message sent from the hard disk, and determine whether the response message is a response message generated for the SAS protocol message according to the SAS protocol message identifier and the response message identifier.

[0058] The response message includes a response message identifier.

[0059] In some optional embodiments, the collection device obtains the service number corresponding to the SAS protocol message; allocates a first descriptor to the SAS protocol message in the configuration area; receives a response message sent from the hard disk; and searches in the configuration area based on the response message identifier to determine whether the SAS protocol message identifier included in the descriptor is consistent with the response message identifier.

[0060] If so, the collection device determines that the reply message is a response message generated for the SAS protocol message, stores the reply message identifier and the reply message index in the first descriptor, obtains the target descriptor corresponding to the SAS protocol message and the reply message, and copies the reply message to the corresponding position in the protocol area according to the reply message index.

[0061] The first descriptor includes a SAS protocol message identifier, an index of the SAS protocol message, and a service number corresponding to the SAS protocol message.

[0062] In the embodiment of the present invention, the target descriptor includes a SAS protocol message identifier, an index of the SAS protocol message, a service number corresponding to the SAS protocol message, a response message identifier, and an index of the response message.

[0063] In one example, when the server sends a SAS protocol message to the hard disk, the collection device obtains the service number corresponding to the SAS protocol message in the configuration area of ​​the shared memory.

[0064] In some optional implementations, the collection device copies the SAS protocol message to a corresponding position in the protocol area according to an index of the SAS protocol message.

[0065] Optionally, the collection device retrieves the SAS protocol message identifier included in the non-existent descriptor in the configuration area based on the reply message identifier and finds that it is consistent with the reply message identifier, then determines that the reply message is not a response message generated for the SAS protocol message, and allocates a second descriptor to the reply message in the configuration area.

[0066] The second descriptor includes a response message identifier, an index of the response message, and a response service number of the response message.

[0067] It can be understood that the collection device determines that the reply message is not a response message generated for the SAS protocol message, which means that the reply message may be an invalid message or a reply message of other SAS protocol messages. In this case, the reply message identifier, the reply message index and the reply service number of the reply message need to be stored in the second descriptor to facilitate subsequent judgment of whether other SAS protocol messages are fault messages.

[0068] S203: If yes, send the index of the response message to the analysis device.

[0069] Among them, the analysis device is used to locate the service number corresponding to the SAS protocol message in the shared memory of the server and obtain the response message based on the index of the response message, and determine whether the SAS protocol message is a fault message and locate the service corresponding to the SAS protocol message based on the service number and the response message.

[0070] It can be understood that the relevant information of the response message and the SAS protocol message are all stored in the same descriptor, which makes it easier for the subsequent analysis device to determine the target descriptor according to the index of the response message and then find the service code corresponding to the SAS protocol message.

[0071] Based on the above S201-S203, the collection device can receive the index of the response message sent from the collection device when the response message is a response message generated for the SAS protocol message, obtain the response message in the shared memory of the server based on the index of the response message, and determine the service number corresponding to the SAS protocol message, and determine whether the SAS protocol message is a fault message based on the status code and the preset correspondence; if so, locate the service corresponding to the SAS protocol message based on the service number and the service mapping table in the shared memory.

[0072] Since the reply message is a response message generated for the SAS protocol message, the reply message can be obtained in the shared memory of the server according to the index of the reply message, and the business number corresponding to the SAS protocol message associated with the index of the reply message can be determined. This shared memory method can reduce data copying between devices and improve efficiency.

[0073] In addition, based on the status code of the response message and the preset correspondence, it can be determined whether the SAS protocol message corresponding to the response message is a fault message. When it is determined to be a fault message, the service code is determined based on the one-to-one correspondence between the service number and the service mapping table in the shared memory, and the service corresponding to the faulty SAS protocol message is accurately located. This achieves the identification of the service corresponding to the fault message with a single confirmation, avoiding the time-consuming multiple identifications. This method improves the customer experience, shortens the time to locate the service corresponding to the fault message, and thus reduces the location cost.

[0074] In this embodiment, a method for locating a fault message is provided, which can be used in the above-mentioned analysis device. Figure 4 FIG. 1 is a flow chart of a method for locating a fault message according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0075] S401: In the case where the reply message is a response message generated for the SAS protocol message, an index of the reply message sent from the collection device is received.

[0076] S402: Based on the index of the response message, obtain the response message from the shared memory of the server, and determine the service number corresponding to the SAS protocol message.

[0077] The response message carries a status code.

[0078] In some optional embodiments, the analysis device obtains the response message in the shared memory of the server based on the index of the response message, and determines the service number corresponding to the SAS protocol message, including: obtaining the response message in the shared memory of the server based on the index of the response message; and screening the target descriptor including the index of the response message among multiple descriptors in the shared memory.

[0079] The target descriptor is a shared descriptor corresponding to the SAS protocol message and the response message, and the target descriptor includes the service number corresponding to the SAS protocol message.

[0080] S403: Determine whether the SAS protocol message is a fault message according to the status code and the preset correspondence.

[0081] The status code indicates the status of the response message and can indicate various states of the SAS protocol message.

[0082] Exemplarily, taking the status code as the first status code, the second status code or the third status code as an example, the preset corresponding relationship includes that the first status code corresponds to the SAS protocol message as a fault message, the second status code corresponds to the SAS protocol message as a normal message, and the third status code corresponds to the SAS protocol message as an invalid message.

[0083] It is understandable that the status code may also include more status codes, and different status codes indicate different statuses of the SAS protocol message.

[0084] S404: If yes, locate the service corresponding to the SAS protocol message based on the service number and the service mapping table in the shared memory.

[0085] The service mapping table includes multiple services and a service number corresponding to each service.

[0086] It can be understood that the analysis device matches the corresponding

[0087] In some optional implementations, the analysis device determines the cause of the failure of the SAS protocol message based on the status code and the status code conversion table; stores the cause of the failure in a shared memory, and deletes the target descriptor, the SAS protocol message, and the response message from the shared memory.

[0088] The status code conversion table is used to convert the status code into the fault cause.

[0089] For example, taking the status code "CHECK_CONDITION error code" as an example, the analysis device converts the "CHECK_CONDITION error code" into the fault cause as illegal command parameters, that is, the sent parameters are incorrect, based on the "CHECK_CONDITION error code" and the status code conversion table.

[0090] It can be understood that the analysis device deletes the target descriptor, SAS protocol message and response message from the shared memory, and can reset the target descriptor to an unused state to be allocated to the next message.

[0091] In some optional implementations, the analyzing device obtains a message type of the SAS protocol message, and determines the message content corresponding to the SAS protocol message according to the message type of the SAS protocol message.

[0092] The message type may be a data message type or a management message type.

[0093] It is understood that if the message type is a data message type, the analysis device determines that the message content corresponding to the SAS protocol message is the SAS protocol message. If the message type is a management message type, the analysis device determines that the message content corresponding to the SAS protocol message is the specific meaning of the message content parsed according to the protocol.

[0094] Similarly, the analysis device obtains the message type of the response message, and determines the message content corresponding to the response message according to the message type of the response message.

[0095] It is understandable that the display module included in the analysis device can display the message content corresponding to the SAS protocol message, the message content corresponding to the response message, the fault cause and the business corresponding to the SAS protocol message, so that management personnel can find relevant information of the fault message in time.

[0096] Based on the above S401-S404, when the reply message is a response message generated for the SAS protocol message, the index of the reply message sent from the collection device can be received, and based on the index of the reply message, the reply message can be obtained in the shared memory of the server, and the service number corresponding to the SAS protocol message can be determined. According to the status code and the preset correspondence, it is determined whether the SAS protocol message is a fault message; if so, the service corresponding to the SAS protocol message is located based on the service number and the service mapping table in the shared memory.

[0097] Since the reply message is a response message generated for the SAS protocol message, the reply message can be obtained in the shared memory of the server according to the index of the reply message, and the business number corresponding to the SAS protocol message associated with the index of the reply message can be determined. This shared memory method can reduce data copying between various devices and improve efficiency. In addition, based on the status code of the reply message and the preset correspondence, it can be determined whether the SAS protocol message corresponding to the reply message is a fault message. Since the business number and the business mapping table in the shared memory have a one-to-one correspondence, it is possible to accurately locate the business corresponding to the SAS protocol message based on the determined business code, avoiding multiple fault message positioning of the corresponding business, resulting in a long cycle for resolving faults, improving customer experience, and reducing the cost of locating fault messages.

[0098] In this embodiment, another method for locating fault messages is provided, such as Figure 5 As shown, Figure 5 FIG. 1 is a flow chart of another method for locating a fault message according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0099] S501: The collection device obtains a SAS protocol message sent by the server to the hard disk and an index of the SAS protocol message in the first descriptor.

[0100] S502: The collection device obtains the service number corresponding to the SAS protocol message.

[0101] S503: The collection device receives a response message sent from the hard disk.

[0102] S504: Determine, according to the SAS protocol message identifier and the reply message identifier, whether the reply message is a response message generated for the SAS protocol message.

[0103] S505: If yes, the collecting device sends the index of the response message to the analyzing device.
