BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a flowchart of the health monitoring method of the present invention.

[0021] Figure 2 It is an architecture diagram of the health monitoring method system of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0022] Please refer to Figure 1 , the present invention provides a health monitoring method for an application system, including:

[0023] S1: Obtain the page data during the operation of the application system, and determine the final page that has been loaded;

[0024] S2: Scan each page area in the final page, and select the page area with errors in the final page as the analysis area;

[0025] S3: Determine whether the result data corresponding to each analysis area satisfies the conditions of the preset error status code. If it satisfies, control the output of the corresponding error status code. If it does not satisfy, analyze the combination situation of the error status codes forming the result data;

[0026] S4: Evaluate the health status of the application system according to the obtained error status code situation.

[0027] It is not difficult to find from the above that during the health monitoring of the application system, by obtaining the page data corresponding to each moment during the operation of the application system, the status code situation corresponding to each page data can be further determined, and then the current operation situation of the application system can be determined. Moreover, when there is no corresponding interface data generated, it can be determined that the final page obtained after loading is completed. After obtaining this final page, by scanning the final page, all page areas in the final page can be identified. And according to the situation of the page areas, the page areas with errors in the final page are initially determined, and the page areas with errors are used as the analysis areas for error situations. When analyzing the analysis areas, by judging the specific situation of the result data with errors in the analysis areas, specifically, by determining whether the result data meets the preset error status code conditions. Further determine whether the formation of the analysis area is caused by only one error status code. If so, there is no need for further analysis, and the corresponding error status code can be directly output. If a certain error status code cannot be queried to form the result data corresponding to the analysis area, the error status code combination corresponding to the formation of the result data will be further analyzed, that is, the situation where the result data is caused by the error status code combination. And according to the obtained error status code situation, it can be further determined whether the application system is in a healthy state. Through the above method, it is possible to realize the real-time health status of the processing process of the application system after inputting parameters to the application system, thus ensuring the operation safety of the application system.

[0028] Among them, in step S1, obtaining the page data during the operation of the application system includes: collecting the processing instruction signals of the application system and intercepting the real-time page images during the operation of the application system and monitoring the interface data during the operation of the application system, and sequentially judging each moment corresponding real-time page images and whether the interface data meets the predetermined conditions of the correct status code If it is satisfied, control to continue to determine the correct status code corresponding to each moment until completion. If it is not satisfied, control to record the page images starting from when it is not satisfied where are different types of correct status codes, is the number of correct status codes.

[0029] ​In an embodiment of the present invention, when obtaining page data during the operation of an application system, after input parameters are input into the application system, the application system starts to run, and at the same time, it monitors the start processing instruction during the operation of the application system. When a processing instruction signal is collected, it controls the start of real-time interception of the real-time page image during the operation of the application system and also monitors the interface data during the operation of the application system. And it determines whether the corresponding real-time page image and the interface data meet the predetermined conditions of the correct status code . That is to say, the real-time page image corresponding to each correct status code and the interface data are in a determined state. Therefore, when it is satisfied, it means that the current real-time page image and the interface data meet the requirements of the set correct status code . If not satisfied, it indicates that there are errors in the real-time page image and the interface data. Therefore, the page images starting from when it is not satisfied can be recorded and stored for further analysis.

[0030] Furthermore, in step S1, determining the final page that has been loaded completely includes: monitoring and collecting the control signal when the interface data stops outputting, and controlling to obtain the page image corresponding to the moment when the interface stops outputting as the final page .

[0031] In an embodiment of the present invention, during the process of page loading, when the real-time page image no longer changes and it is monitored that the interface data stops outputting, collect the corresponding control signal to control the acquisition of the page image in this state. And this page image is the final page .

[0032] Still further, in step S2, it includes: searching for the correct status code that is closest to the reaction result of each page area in the final page, controlling the output of the error page area that is inconsistent with the correct status code , and taking the error page area as the analysis area.

[0033] In an embodiment of the present invention, when determining the analysis area for the final page , by first scanning the final page ​, determine each page area After that, by searching for each page area obtained The closest correct status code . Furthermore, query to obtain the page area That is different from the correct status code Among the error page areas , and based on the obtained error page area , to determine the analysis area. The situation of the error status code corresponding to the correct status code formed can be obtained more quickly .

[0034] Specifically, in step S3, before analyzing the combination of error status codes of the formed result data, it includes: establishing a mirror model corresponding to the application system, and the mirror model stores the result data output by the mirror model And the result data Input parameters that are mutually mapped .

[0035] In an embodiment of the present invention, after selecting the analysis area, by determining whether the result data corresponding to each analysis area meets the corresponding requirements of the preset error status code, it is determined whether there is an error status code that can meet the result data corresponding to the analysis area of the final page . Before the judgment, it is also necessary to establish a mirror model corresponding to the application system. The mirror model can reach the same running state as the application system before problems occur through input parameters, that is, accurate original result data can be obtained . That is to say, through the input parameters , the result data Can be accurately mapped. Thus, the accuracy of analyzing the combination of error status codes of the result data formed by the final page is ensured.

[0036] Preferably, in step S3, analyzing the combination of error status codes of the formed result data includes: splitting the obtained incorrect result data Into Combination forms of error status codes To obtain the error status code combination , according to the error status code combination The corresponding result data Sharing ratio , to obtain the adjusted result data , running the original input parameters Through the mirror model to obtain the original result data , judge the adjusted result data Whether it is the same as the original result data at the time of original input If they are the same, control the output of the corresponding error status code combination If they are not the same, output the output result data as a new error status code .

[0037] In an embodiment of the present invention, when analyzing and processing the error status code combination, by according to the error result data query all error status codes, and split the result data into a combination form consisting of types of error status codes to obtain the error status code combination . Since each error status code corresponds to its own weight, that is, the sharing ratio. Therefore, the sharing ratio of the result data corresponding to each error status code combination . That is corresponds to , corresponds to , , and so on. Thus, the adjusted result data after being processed by the sharing ratio is obtained . This adjusted result data corresponds to, that is, after knowing the error status code combination , the result data is adjusted by the sharing ratio to achieve the purpose of restoring and adjusting the result data to the original data. Furthermore, after obtaining the adjusted result data , it is also necessary to further compare it with the original result data output when the mirror model runs using the input parameters . Then determine whether the error status code combination can meet the requirement of restoring to the original result data . And when it can be satisfied, continue to output the error status code combination as the analysis result of the error occurrence. When it is not satisfied, the formed result data will be used as a new error status code and can be marked as a newly added error status code . Thus, when a new error occurs, the system record can be completed in a timely manner, ensuring the convenience of system error recognition and thus meeting the health monitoring requirements of the application system.

[0038] Specifically, according to the error status code combination the corresponding result data sharing ratio , the adjusted result data is obtained. The original input parameters are run through the mirror model to obtain the original result data . It is judged whether the adjusted result data is the same as the original result data at the time of original input , including: finding the error status code combination the th error status code for each result data influence factor , the th error status code and the sharing ratio corresponding to each result data . , …, , the adjusted result data is obtained. It is judged whether it corresponds to map the corresponding , where d is the number of error status codes and f is the number of result data.

[0039] In an embodiment of the present invention, in the process of judging whether the adjusted result data , sharing ratio and result data is the same as the original result data at the time of original input , it is necessary to first query the influence factor of each error status code in the error status code combination on different types of result data . According to the influence factor , the aforementioned sharing ratio can be further determined. That is, is obtained. , , …, . And the adjusted result data is obtained. After obtaining the adjusted result data corresponding to each result data ​​ After that (where f is the number of result data), further determine whether it is the same as the original result data If they are exactly the same, it indicates that the error status code is accurate, and the corresponding error status code combination is output If they are not the same, it means that the existing error status code is difficult to conform to the result determination of the current result data Therefore, a new error status code will be added so that when such a problem occurs again next time, the newly added error status code can be directly output .

[0040] Furthermore, in S4, according to the obtained error status code situation, evaluate the health status of the application system, including: when obtaining the error status code , query the error severity factor corresponding to each error status code , and calculate the health index of the current application system based on the error severity factor and the basic health index ; when obtaining the newly added error status code , then determine the corresponding health index according to the difference degree between and the corresponding ; .

[0041] In an embodiment of the present invention, when obtaining the error status code situation, there will be at least two health evaluation methods. That is, when obtaining the error status code , that is, when the error status code is a combination, query the error severity factor corresponding to each error status code . And further calculate the health index based on the basic health index ; when the error status code is the newly added error status code , then determine the corresponding health index according to the difference or correlation degree between and the corresponding . Of course, when the error status code exists alone, that is, it can directly reflect the situation of the final page of the application system, the health index of each individual error status code will be output

[0042] .

[0042] Furthermore, after step S4, it also includes: judging the health index Whether the preset requirements are met. If not, control the retrieval of each error status code and the corresponding optimization strategy to analyze and process the application system

[0043] In an embodiment of the present invention, before determining the optimization strategy for the application system, it is necessary to monitor the health index of the application system. When the health index meets the requirements, the real-time optimization strategy is not controlled. When it does not meet the requirements, according to the formed error status code or the newly added error status code , it is processed through the corresponding optimization strategy

[0044] As Figure 2 shown, the present invention also provides a health monitoring system for an application system, including: a page confirmation unit, which obtains the page data during the operation of the application system and determines the final page that has been loaded; a region analysis unit, which scans each page region in the final page and selects the page region with an error in the final page as the analysis region; a result analysis unit, which determines whether the result data corresponding to each analysis region meets the conditions of the preset error status code. If it meets, it controls the output of the corresponding error status code. If it does not meet, it analyzes the combination of error status codes of the result data; and a status evaluation unit, which evaluates the health status of the application system according to the obtained error status code situation

[0045] In an embodiment of the present invention, in the health monitoring system of the application system of the present invention, the page confirmation unit is used to obtain the page data at each moment during the operation of the application system, and at the moment when the application system finishes running, the corresponding final page is output. And the region analysis unit is used to scan the final page to determine the situation of each page region in the final page. Based on this, according to the correct status code, the page region with an error in the page is further selected as the analysis region. The result analysis unit is used to analyze the result data identified by the analysis region to determine whether it meets the conditions of the preset error status code. And when a certain error status code is met, the error status code can be directly output. When the error status code is not single, further selection of the error status code combination is used to analyze whether it can meet the requirements of the original result data. If it meets, the corresponding error status code combination can be output, and when it does not meet, the result data is recorded as a new error status code. And the status evaluation unit is used to evaluate the health status of the application system in the case of a single error status code, the case of an error status code combination, and the case of a new error status code

[0046] In summary, the present invention obtains and scans the page data during the operation of the application system to obtain the status code situation corresponding to each page during the operation process, so as to determine the operation status of the application system. When the obtained page data no longer changes and the interface data loading is completed, the obtained page can be determined as the final page. Then, the page area of the final page is identified. When it is inconsistent with the correct status code, the incorrect page area is output as the analysis area to analyze the corresponding error status code. When the corresponding error status code is directly identified, the result can be directly output and the health assessment of the application system can be performed. When the fault of the current application system cannot be determined by a single error status code, by selecting a combination of multiple error status codes, when the current result data is generated, the original result under the assumption that the error status code does not appear is analyzed, and then the adjusted result data is obtained. And then the correct input parameters are run using the mirror model to obtain the correct original result data. Then, the adjusted result data is compared with the original result data to further determine whether the current combination of error status codes is in line. If it is in line, the overall health status level of the application system is determined according to the current combination of error status codes. When the adjusted result data is inconsistent with the original result data, new error status codes will be further output to evaluate the health of the application system based on the degree of inconsistency between the adjusted result data and the original result data. Through the above method, the real-time analysis of the health of the application system can be more accurately realized, thus ensuring the safety and stability of the application system during the operation process. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
