The existing monitoring system mainly focuses on detecting and handling system-level failures, such as hardware failures and network interruptions.

[0003] However, the high reliability of data nodes not only needs to pay attention to failures caused by these non-subjective factors, but also lacks attention to intentional intrusions into the system such as artificially changing data node files. For example, when someone accesses a data node without authorization and modifies key files, the existing system may not be able to detect and prevent such behavior in a timely manner, and lacks an effective monitoring and response mechanism for abnormal operations at the file level. In addition, the existing technology is also insufficient in distinguishing between normal database business operations and abnormal operations, and may misreport or miss certain important abnormal situations. The existing technology is insufficient in the flexible configuration of monitoring parameters, the customization of abnormal scenarios, and the personalized setting of fault handling measures. This limits the ability of system administrators to adjust monitoring strategies according to actual needs, and reduces the adaptability and efficiency of the monitoring system.

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] See also Figure 1 , Figure 1 This is a flow chart of an embodiment of a data node monitoring method provided by the present invention, and the method specifically comprises the following steps:

[0050] S100, obtaining metadata information of a data node, and sending the metadata information to a monitoring module;

[0051] S200, the monitoring module sends the path information in the metadata information to the file detection module;

[0052] S300, detecting whether there is a change operation on the path information by the file detection module, and if there is a change operation on the path information, reporting the operation information of the path information to the monitoring module;

[0053] S400, the monitoring module determines whether the operation information is an abnormal operation, and implements a fault handling strategy when the change operation is an abnormal operation.

[0054] In this embodiment, in actual application, the method can be gradually formed through the following steps: first, identify the monitoring requirements of the data node file change operation, and determine the metadata information that needs to be collected; then, send the path information in the metadata information to the file detection module through the monitoring module, so that the file detection module can monitor the changes of the path information in real time; once the file detection module detects the change operation of the path information, it immediately reports the operation information to the monitoring module; finally, the monitoring module analyzes the operation information, determines whether it is an abnormal operation, and takes a fault handling strategy in time when an abnormal operation is detected. Effectively monitor the file change operation of the data node, and take fault handling measures in time when an abnormal operation is detected, thereby improving the security and reliability of the system.

[0055] Furthermore, metadata information refers to various key information related to the data node, including but not limited to the file directory of the data node (such as the data directory, log directory, etc.), the IP of the data node management module, and the user name. The monitoring module is responsible for receiving and processing this metadata information, and sending the path information therein to the file detection module. The file detection module is responsible for real-time monitoring of the path information, detecting whether there is a change operation, and reporting the detected operation information to the monitoring module. After receiving the operation information, the monitoring module determines whether the operation is an abnormal operation, and adopts the corresponding fault handling strategy in the case of abnormal operation.

[0056] In one embodiment, obtaining metadata information of the data node and sending the metadata information to the monitoring module includes:

[0057] Control the monitoring switch and set monitoring parameters according to monitoring requirements;

[0058] Configure fault handling measures based on abnormal scenarios;

[0059] Get metadata information of data nodes;

[0060] The monitoring parameters, metadata information and fault handling measures are sent to the monitoring module through the front-end page.

[0061] In this embodiment, on the monitoring setting page, the user can view the status of the current monitoring switch, control the monitoring switch according to the monitoring requirements, and set the monitoring parameters. In this way, the monitoring function can be flexibly turned on or off, and the parameters can be adjusted according to specific requirements to adapt to different monitoring requirements. Configure fault handling measures according to abnormal scenarios. By pre-configuring fault handling measures for different abnormal scenarios, appropriate handling measures can be taken quickly when an abnormality occurs to improve the reliability of the system. Obtain the metadata information of the data node. Through this step, detailed information of the data node can be obtained to provide basic data for subsequent monitoring. The monitoring parameters, metadata information and fault handling measures are sent to the monitoring module through the front-end page, so that the monitoring module can obtain the latest monitoring parameters and metadata information in real time, and process according to the preset fault handling measures. Through the above technical means, the technical problem of how to obtain the metadata information of the data node and send it to the monitoring module is solved, thereby realizing effective monitoring of the data node.

[0062] Specifically, the monitoring switch and monitoring parameters can be set through the front-end configuration interface. Users can turn on or off the monitoring function according to actual needs, and adjust the monitoring parameters to adapt to different monitoring scenarios. For example, when the system load is high, the monitoring frequency can be appropriately reduced to reduce system overhead. Fault handling measures for abnormal scenarios can be pre-configured in the system, including but not limited to restarting services, switching nodes, sending alarms, etc. When the monitoring module detects abnormal operations, it can respond quickly according to the preset handling measures to ensure the stable operation of the system. Metadata information can be obtained through the system interface. The system will collect metadata information of data nodes regularly or in real time, and send it to the monitoring module through the front-end page to ensure that the monitoring module obtains the latest monitoring data.

[0063] This application improves the adaptability of the system through flexible monitoring switches and parameter settings; improves the response speed and processing capabilities of the system in abnormal situations through preset fault handling measures; and ensures the timeliness and accuracy of monitoring data through real-time acquisition and transmission of metadata information. Compared with the existing technology, this application not only focuses on failures caused by non-subjective factors, but also pays special attention to intentional intrusion into the system such as artificially changing data node files, thereby comprehensively improving the high reliability and high availability of data nodes.

[0064] In one embodiment, the monitoring module sends the path information in the metadata information to the file detection module, including:

[0065] The monitoring module receives metadata information transmitted by the front-end page, parses the metadata information, and obtains path information;

[0066] The path information is sent to the file detection module, and a monitoring instruction is sent to the file detection module.

[0067] In this embodiment, after the monitoring module receives the metadata information transmitted by the front-end page, it first parses the information. Specifically, the parsing process can be implemented by preset rules or algorithms, such as regular expression matching, keyword extraction, etc., so as to accurately obtain the path information. Then, the monitoring module sends the parsed path information to the file detection module through a network interface or other communication methods. At the same time, the monitoring module will also generate corresponding monitoring instructions, and send the instructions and the path information to the file detection module together. After receiving the path information and the monitoring instructions, the file detection module starts the monitoring operation of the path information and detects whether there is a change operation on the path information. When a change operation is detected, the file detection module reports the changed operation information to the monitoring module.

[0068] Through the above technical content, it is ensured that the file detection module can detect path change operations based on this information, effectively solve the path information transmission and monitoring problems of metadata information, improve the system's monitoring and detection efficiency, and ensure the high reliability and security of data nodes.

[0069] In one embodiment, the detecting by the file detection module whether there is a change operation on the path information, and if there is a change operation on the path information, reporting the operation information of the path information to the monitoring module includes:

[0070] The file detection module receives the path information and monitoring instructions;

[0071] In response to the monitoring instruction, the path information is monitored to detect whether there is a change operation on the path information;

[0072] When there is a change operation on the path information, the operation information of the path information is reported to the monitoring module.

[0073] In this embodiment, the file detection module receives the path information and the monitoring instruction, and monitors the path information in response to the monitoring instruction to detect whether there is a change operation on the path information. When there is a change operation on the path information, the file detection module reports the operation information of the path information to the monitoring module. In this way, the change operation of the path information can be monitored in real time, and the change information can be reported in time, thereby providing a basis for further abnormal operation judgment and fault handling. Through the above scheme, the problem of detecting the change operation of the path information is solved, so that the system can timely discover and report the change operation of the path information, and provide reliable data support for subsequent abnormal judgment and fault handling.

[0074] Specifically, the file detection module can be implemented by periodically checking the change of path information through polling; another way is that the file detection module monitors the change operation of path information in real time through the event notification mechanism of the file system. These implementation methods can effectively detect the change operation of path information and report the operation information to the monitoring module.

[0075] This embodiment can effectively solve the problem of detecting path information change operations. Compared with the prior art, this application can monitor the path information change operation in real time and report the change information in a timely manner, thereby providing reliable data support for further abnormal operation judgment and fault handling. This can improve the system's response speed to abnormal operations and reduce the risk of system failures caused by path information changes.

[0076] In one embodiment, the monitoring module determines whether the operation information is an abnormal operation, and implements a fault handling strategy when the change operation is an abnormal operation, including:

[0077] The monitoring module determines whether the operation information is an abnormal operation;

[0078] If the operation information is a database business operation, the change operation is a normal operation;

[0079] If the operation information is a non-database business operation, the change operation is an abnormal operation, and a fault handling measure is implemented according to the abnormal operation type.

[0080] In this embodiment, the monitoring module first determines whether the operation information is an abnormal operation; when the operation information belongs to a database business operation, it is regarded as a normal operation and no fault handling measures are taken; when the operation information belongs to a non-database business operation, it is regarded as an abnormal operation, and corresponding fault handling measures are taken according to the type of abnormal operation. This method effectively identifies and handles abnormal change operations of data nodes by distinguishing between database business operations and non-database business operations, thereby improving the reliability and security of the system.

[0081] Furthermore, the monitoring module can determine the type of operation information through preset rules or models. Specifically, database business operations may include common database query, update, insert and delete operations, while non-database business operations may include modifications to system files, unauthorized access, etc. Based on these rules, the monitoring module can quickly and accurately classify the operation information.

[0082] Specifically, when the monitoring module determines that the operation information is a non-database business operation, different fault handling measures can be taken according to the specific type of abnormal operation. For example, for unauthorized file modification, an alarm message can be immediately sent to the system administrator and relevant logs can be recorded; for potential malicious attacks, the system protection mechanism can be triggered to prevent further operations and conduct a detailed security review.

[0083] The method described in this application achieves efficient identification and processing of abnormal data node change operations by accurately distinguishing between database business operations and non-database business operations. This not only improves the reliability and security of the system, but also enables rapid response and processing when abnormal operations occur, reducing potential security risks and the impact of system failures.

[0084] In one embodiment, if the operation information is a non-database business operation, the change operation is an abnormal operation, and a fault handling measure is implemented according to the abnormal operation type, including:

[0085] When the fault handling measure is alarm information processing, sending alarm information to the alarm module, and the alarm module displays the alarm information on the front-end page;

[0086] When the fault handling measure is alarm plus node switching processing, the role of the abnormal node is determined. If the abnormal node is an abnormal master node, the monitoring module sends an alarm message to the alarm module and sends a node switching instruction to the node management module.

[0087] In this embodiment, when it is detected that the operation information of the data node is a non-database business operation, it is regarded as an abnormal operation. According to the type of abnormal operation, take corresponding fault handling measures. For alarm information processing, the system will send an alarm message to the alarm module and display the alarm message on the front-end page. For alarm plus node switching processing, the system first determines the role of the abnormal node. If the main node is detected to be abnormal, the monitoring module will send an alarm message to the alarm module, and at the same time send a node switching instruction to the node management module to execute the main and standby node switching operation. After receiving the instruction, the node management module will select the standby node for data synchronization operation and complete the switching of the data node.

[0088] Specifically, the fault handling measures include alarm information processing and alarm plus node switching processing. In the alarm information processing measures, an alarm message is sent to the alarm module and displayed on the front-end page. In the alarm plus node switching processing measures, the role of the abnormal node is first determined. If the main node is abnormal, an alarm message is sent to the alarm module and a node switching instruction is sent to the node management module, and the alarm message is displayed on the front-end page. If the standby node is abnormal, an alarm message is sent to the alarm module, and the alarm message is displayed on the front-end page. Through the mutual cooperation of these technical features, the technical solution of the present application can effectively detect and process abnormal operations caused by non-database business operations of data nodes, ensuring the high reliability and high availability of the system.

[0089] Therefore, this application can effectively avoid data node anomalies caused by human operations by detecting and processing non-database business operations, thereby improving the reliability and availability of the system. Compared with the prior art, this application not only focuses on system failures caused by factors such as network isolation, process anomalies, and hard disk failures, but also pays attention to the potential risks brought by human operations, and provides a comprehensive fault handling strategy.

[0090] In one embodiment, if the abnormal node is an abnormal master node, the monitoring module sends an alarm message to the alarm module and sends a node switching instruction to the node management module, including:

[0091] The node management module receives the node switching instruction sent by the monitoring module and executes the primary and standby node switching operation;

[0092] A standby node is selected according to the node switching priority, and data synchronization operation is performed on the primary node and the standby node to complete the data node switching.

[0093] In this embodiment, the monitoring module first detects whether an abnormality occurs in the main node. When an abnormality is detected, the monitoring module immediately sends an alarm message to the alarm module and sends a node switching instruction to the node management module. After receiving the instruction, the node management module selects a backup node according to the node switching priority. The node management module checks whether the status of the backup node is healthy and can take over the responsibilities of the main node, and selects a backup node that meets the requirements to perform the main and backup node switching operation. Subsequently, the node management module performs data synchronization operations on the main node and the backup node to ensure the consistency and integrity of the data, and finally completes the switching of the data node, updates the system configuration, and redirects the traffic and requests from the failed main node to the backup node. After the node switching, it verifies whether the backup node has successfully taken over the responsibilities of the main node and whether the service is running normally, ensuring that it can be executed quickly in the event of an actual certification failure, minimizing the service interruption time.

[0094] By effectively solving the data node switching problem when the master node is abnormal, it ensures that the system can quickly resume normal operation when the master node fails, avoiding data loss and service interruption. Compared with the prior art, this application not only focuses on failures caused by non-subjective factors, but also effectively monitors and handles intentional intrusions into the system such as manually changing data node files, further improving the security and reliability of the system.

The file detection module detects whether there is a change operation in the path information, and reports the operation information of the path information to the monitoring module. The monitoring module determines whether the operation information is an abnormal operation, if the operation information is an abnormal operation, a real-time fault handling operation is performed, and the fault handling operation is determined to be only an alarm, or an alarm plus node switching, when only an alarm is given, the alarm information is sent to the alarm module; when an alarm plus node switching is performed, it is determined whether the abnormal node is the main node or the standby node, if the main node is abnormal, the alarm information is sent to the alarm module, and the node switching instruction is sent to the node management module to implement the node switching operation; if the standby node is abnormal, the alarm information is sent to the alarm module, and the alarm information is sent to the front-end page for display, providing a reliable standby node, and achieving better maintenance of the stable operation of the database system.
