Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of computer technology, and more particularly to a fault diagnosis and alarm method, apparatus, electronic device, and computer-readable medium. Background Art

[0002] Fault diagnosis and alarming are methods for diagnosing and alerting abnormalities during program or software execution. Currently, these methods typically rely on manual detection, rule-based techniques, or counting thresholds to detect abnormalities and generate alarms.

[0003] However, when using the above methods for fault diagnosis and alarm, the following technical problems often occur:

[0004] Relying on manual alarm generation makes the final alarm results highly susceptible to subjective perception and experience, making it difficult to issue alarms in a timely manner. Rule-based technologies often structure expert knowledge into rules, which are then used to detect faults and issue alarms. However, the rapid pace of program and software updates makes it difficult to detect faults introduced by these updates using existing rules. This makes it difficult to accurately detect anomalies and issue alarms, impacting the normal operation of the program or software. Counting and threshold-based technologies record the values of various indicators during program or software operation and perform fault diagnosis and alarms solely by comparing these indicators with thresholds. This relies heavily on thresholds, resulting in inaccurate alarm results. Consequently, it is difficult to promptly detect and resolve anomalies during program or software operation.

[0057] Continue to refer Figure 2 , shows a process 200 of some embodiments of the fault diagnosis and alarm method according to the present disclosure. The fault diagnosis and alarm method includes the following steps:

[0058] Step 201: Acquire a set of termination point information.

[0059] In some embodiments, the execution subject of the fault diagnosis and alarm method (such as Figure 1The computing device 101 shown can read a set of termination point information from a log file via a wired or wireless connection. The termination point information can be used to represent a termination point. The termination point can be a location where an operational anomaly occurs during the execution of a software or program. The log file records various types of information about the software or program during its execution. The termination point information in the termination point information set can include termination point type information and a termination point call information sequence. The termination point type information can include the type of software or program flow to which the termination point belongs. The termination point type information can include a primary, secondary, or tertiary flow. The impact of primary, secondary, and tertiary flows on the normal operation of the program or software decreases in descending order. The termination point call information in the termination point call information sequence can include time period information, termination counts, and call counts. The time period information, termination counts, and call counts in the termination point call information can indicate the number of times the termination point experienced operational anomalies and the number of times it was called during the time period represented by the time period information. The individual termination point call information in the termination point call information sequence can be arranged in chronological order according to the time period information. The time period represented by the time period information included in the head of the termination point calling information sequence may be earlier than the time period represented by the time period information included in the tail of the termination point calling information sequence.

[0060] Step 202: Select termination point information that meets the screening conditions from the termination point information set according to the termination times and the call times as valid termination point information to obtain a valid termination point information set.

[0061] In some embodiments, the execution entity selects termination point information that meets the screening conditions from the termination point information set as valid termination point information based on the termination count and the call count, and obtains the valid termination point information set, which may include the following steps:

[0062] In the first step, the ratio of the sum of the number of terminations in the termination point call information sequence included in each termination point information in the termination point information set to the sum of the number of calls is determined as the termination point importance. The screening condition may be that the termination point importance corresponding to the termination point information is greater than a preset termination point importance threshold.

[0063] In the second step, according to the importance of the termination point, termination point information that meets the above screening conditions is selected from the above termination point information set as valid termination point information to obtain a valid termination point information set.

[0064] Step 203 : determining the failure risk rate and failure risk growth rate of the termination point represented by each valid termination point information in the valid termination point information set.

[0065] In some embodiments, the execution subject determines the failure risk rate and failure risk growth rate of the termination point represented by each valid termination point information in the valid termination point information set, which may include the following steps:

[0066] In the first step, the termination point validity score value of the valid termination point information is determined as the failure risk rate.

[0067] In the second step, the difference between the ratio of the number of terminations to the number of calls in the last termination point call information in the termination point call information sequence included in the above-mentioned valid termination point information and the ratio of the number of terminations to the number of calls in the first termination point call information is determined as the above-mentioned fault risk growth rate.

[0068] Step 204 : Determine the overall risk coefficient of the termination point represented by each valid termination point information in the valid termination point information set based on the termination point type information and the termination point call information sequence.

[0069] In some embodiments, the execution entity determines the overall risk coefficient of the termination point represented by each valid termination point information in the valid termination point information set based on the termination point type information and the termination point call information sequence, which may include the following steps:

[0070] In the first step, an independent risk coefficient is determined as the product of the failure risk rate corresponding to each valid termination point information in the valid termination point information set and the type weight value corresponding to the termination point type information included in the valid termination point information, thereby obtaining an independent risk coefficient set. The type weight value corresponding to the termination point type information may be preset.

[0071] In the second step, the arithmetic mean of each independent risk coefficient in the above independent risk coefficient set is determined as the above overall risk coefficient.

[0072] Step 205 , in response to determining that there is a failure risk rate greater than a failure risk rate threshold, a failure risk growth rate greater than a failure risk growth rate threshold, or an overall risk coefficient greater than an overall risk coefficient threshold, performing an alarm operation.

[0073] In some embodiments, the execution subject may execute an alarm operation in response to determining that there is a failure risk rate greater than a failure risk rate threshold, a failure risk growth rate greater than a failure risk growth rate threshold, or that the overall risk coefficient is greater than an overall risk coefficient threshold. The failure risk rate threshold, the failure risk growth rate threshold, and the overall risk coefficient may be pre-set. In practice, the values of the failure risk rate threshold, the failure risk growth rate threshold, and the overall risk coefficient may be set according to the actual application scenario, which is not limited here. The alarm operation may include sending an alarm message to a monitoring terminal. It may also include controlling an alarm device to emit an alarm tone, etc.

[0074] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the fault diagnosis and alarm methods of some embodiments of the present disclosure, timely and accurate alarms can be issued for abnormal situations that occur during the operation of a program or software. Specifically, the reason why the alarms of the relevant fault diagnosis and alarm methods are not timely and accurate is that the alarm results of manual alarms are easily affected by people's subjective cognition and experience, the speed of rule updates in rule-based technologies is slower than the speed of program and software update iterations, and the reliance on thresholds in counting and threshold-based technologies is too high. Based on this, the fault diagnosis and alarm methods of some embodiments of the present disclosure determine the parameters related to the alarm based on the termination point information of each termination point obtained, without relying on externally formulated rules and set thresholds. The parameters related to the alarm can be determined only based on the termination point data recorded during the operation of the program or software. In addition, the degree of abnormality during the operation of the program or software is measured from three perspectives: fault risk rate, fault risk growth rate and overall risk, so as to achieve more accurate and comprehensive alarms.

[0075] Further references Figure 3 , which shows a process 300 of another embodiment of the fault diagnosis and alarm method. The process 300 of the fault diagnosis and alarm method includes the following steps:

[0076] Step 301: Acquire a set of termination point information.

[0077] In some embodiments, the execution subject of the fault diagnosis and alarm method (such as Figure 1The computing device 101 shown can obtain a termination point information set via a wired or wireless connection. The termination point information can be used to represent a termination point. The termination point can be a location where an operational anomaly occurs during the execution of a software or program. The termination point information in the termination point information set can include termination point type information and a termination point call information sequence. The termination point type information can include the type of software process or program process to which the termination point belongs. The termination point type information included in the termination point information set can include core process termination points, basic process termination points, or common process termination points. The impact of core process termination points, basic process termination points, and common process termination points on the normal operation of the program or software decreases. The termination point call information in the termination point call information sequence can include time period information, termination counts, and call counts. The time period information, termination counts, and call counts in the termination point call information can indicate the number of times the termination point location experienced operational anomalies and the number of times it was called within the time period represented by the time period information. The individual termination point call information in the termination point call information sequence can be arranged in chronological order based on the time period information. The time period represented by the time period information included in the termination point calling information at the head of the termination point calling information sequence may be earlier than the time period represented by the time period information included in the termination point calling information at the tail.

[0078] Step 302 : Determine the termination point importance of each termination point represented by each termination point information in the termination point information set according to the termination times and the call times, and obtain a termination point importance set.

[0079] In some embodiments, the execution entity may determine the termination point importance by the ratio of the sum of each termination number to the sum of each call number in the termination point call information sequence included in each termination point information in the termination point information set.

[0080] In some optional implementations of some embodiments, the execution entity determines the termination point importance of the termination point represented by each termination point information in the termination point information set based on the termination count and the call count, and obtains the termination point importance set, which may include the following steps:

[0081] In the first step, the information entropy of the termination point represented by each termination point information in the above termination point information set is determined according to the termination number and the call number, and the information entropy set is obtained.

[0082] Optionally, the execution entity determines the information entropy of the termination point represented by each termination point information in the termination point information set according to the termination count and the call count to obtain the information entropy set, which may include the following sub-steps:

[0083] The first sub-step is to segment the termination point call information sequence included in the termination point information to obtain a set of termination point call information sub-sequences. The segmentation of the termination point call information sequence can be performed based on a preset number of termination point call information. Each termination point call information sub-sequence in the set of termination point call information sub-sequences includes the same number of termination point call information as the preset number of termination point call information.

[0084] In the second sub-step, the ratio of the number of terminations to the number of calls in each termination point call information in each termination point call information sub-sequence in the termination point call information sub-sequence set is determined as the termination rate to obtain a termination rate sub-sequence set.

[0085] In the third sub-step, the arithmetic mean of the termination rates in each termination rate sub-sequence in the above termination rate sub-sequence set is determined as the termination probability to obtain a termination probability set.

[0086] The fourth sub-step is to determine the information entropy of the termination point represented by the termination point information based on the termination probability set. The information entropy formula can be used to determine the information entropy of the termination point represented by the termination point information.

[0087] As an example, refer to Figure 4 First, the termination point call information sequence 402 included in the termination point information 401 can be segmented to obtain a termination point call information subsequence set 403. Then, the ratio of the number of terminations to the number of calls in each termination point call information in each termination point call information subsequence in the termination point call information subsequence set 403 is determined as the termination rate, to obtain a termination rate subsequence set 404. Next, the arithmetic mean of the termination rates in each termination rate subsequence in the termination rate subsequence set 404 is determined as the termination probability, to obtain a termination probability set 405. Finally, based on the termination probability set 405, the information entropy 406 of the termination point represented by the termination point information 401 is determined.

[0088] The second step is to normalize each information entropy in the above information entropy set, and use the normalized information entropy as the end point importance to obtain the end point importance set. The end point importance can be determined as the ratio of each information entropy in the above information entropy set to the maximum information entropy in the above information entropy set.

[0089] Therefore, the importance of the termination point can be objectively evaluated using information entropy. The larger the information entropy value, the more important the corresponding termination point is.

[0090] Step 303 : According to the termination point importance set, termination point information meeting the screening condition is selected from the termination point information set as valid termination point information, thereby obtaining a valid termination point information set.

[0091] In some embodiments, the execution entity may select, from the termination point information set, termination point information that satisfies a screening condition as valid termination point information based on the termination point importance set, thereby obtaining a valid termination point information set. The screening condition may be that the termination point importance corresponding to the termination point information is greater than the arithmetic mean of the importances of each termination point in the termination point importance set.

[0092] In some optional implementations of some embodiments, the execution entity selects, based on the termination point importance set, termination point information that meets a screening condition from the termination point information set as valid termination point information to obtain the valid termination point information set, which may include the following steps:

[0093] Based on the preset initial coverage and initial endpoint importance, the following screening steps are performed:

[0094] In the first step, the difference between the endpoint importance corresponding to the initial coverage ratio and the initial endpoint importance is determined as the coverage difference. The initial coverage ratio and initial endpoint importance can be pre-set. The coverage ratio is the percentage of the number of endpoint information in the endpoint information set. The endpoint importance corresponding to the initial coverage ratio can be the smallest endpoint importance among the endpoint importances of the initial coverage ratio before the largest endpoint importance in the endpoint information set.

[0095] In the second step, the difference between the coverage rate corresponding to the initial end point importance and the initial coverage rate is determined as the importance difference. The coverage rate corresponding to the initial end point importance can be the percentage of end point importances greater than or equal to the initial end point importance in the end point importance set.

[0096] In a third step, in response to determining that the coverage difference is less than or equal to the coverage difference threshold and the importance difference is less than or equal to the importance difference threshold, the termination point information having a corresponding termination point importance greater than the initial termination point importance is selected from the termination point information set as valid termination point information, thereby obtaining a valid termination point information set. The coverage difference threshold and the importance difference threshold may be preset.

[0097] Optionally, the execution subject selects, according to the termination point importance set, termination point information that meets a screening condition from the termination point information set as valid termination point information to obtain the valid termination point information set, and may further include the following steps:

[0098] In response to determining that the coverage difference is greater than the coverage difference threshold, or the importance difference is greater than the importance difference threshold, the following adjustment steps are performed:

[0099] In response to determining that the coverage difference is greater than or equal to the importance difference, the value of the initial coverage is adjusted by a preset coverage growth step, and the above screening step is continued according to the adjusted initial coverage.

[0100] Optionally, the execution subject selects, according to the termination point importance set, termination point information that meets a screening condition from the termination point information set as valid termination point information to obtain the valid termination point information set, and may further include the following steps:

[0101] In response to determining that the coverage difference is less than the importance difference, the value of the initial end point importance is adjusted by a preset importance growth step, and the above screening step is continued according to the adjusted initial end point importance.

[0102] Therefore, we can use points with lower endpoint importance as noise endpoints, and dynamically adjust the initial endpoint importance and initial coverage to determine the initial endpoint importance value used to eliminate noise endpoints. This prevents noise endpoints from interfering with the final alarm operation and improves alarm accuracy.

[0103] Step 304 : determining an initial failure risk rate sequence based on the termination point importance corresponding to the valid termination point information and each termination rate subsequence in the termination rate subsequence set.

[0104] In some embodiments, the execution entity may determine the product of the arithmetic mean of each termination rate in the termination rate subsequence and the termination point importance corresponding to the valid termination point information as the initial failure risk rate corresponding to the termination rate subsequence.

[0105] In some optional implementations of some embodiments, the execution entity determines the initial failure risk rate sequence based on the termination point importance corresponding to the valid termination point information and each termination rate subsequence in the termination rate subsequence set, which may include the following steps:

[0106] In the first step, the mode of the termination rate subsequence is determined as the termination rate mode.

[0107] In the second step, the product value of the difference between the last termination rate in the termination rate subsequence and the termination rate mode and the termination point importance corresponding to the valid termination point information is determined as the initial failure risk rate corresponding to the termination rate subsequence.

[0108] Step 305 : Select the last initial failure risk rate from the initial failure risk rate sequence as the failure risk rate of the termination point represented by the valid termination point information.

[0109] In some embodiments, the execution entity may select the last initial failure risk rate from the initial failure risk rate sequence as the failure risk rate of the termination point represented by the valid termination point information.

[0110] Step 306: Generate a failure risk growth rate based on the initial failure risk rate sequence.

[0111] In some embodiments, the execution entity may determine the difference between the last initial failure risk rate and the first initial failure risk rate in the initial failure risk rate sequence as the failure risk growth rate.

[0112] In some optional implementations of some embodiments, the above-mentioned execution entity may determine the failure risk growth rate as the ratio of the difference between the second-to-last initial failure risk rate and the first-to-last initial failure risk rate in the above-mentioned initial failure risk rate sequence to the second-to-last initial failure risk rate.

[0113] Step 307: Determine the core process termination point weight, basic process termination point weight, and termination point importance weight.

[0114] In some embodiments, the execution entity may determine the core process termination point weight, the basic process termination point weight, and the termination point importance weight. The core process termination point, the basic process termination point, and the termination point importance weight may be pre-set.

[0115] In some optional implementations of some embodiments, the execution entity may determine the core process termination point weight, the basic process termination point weight, and the termination point importance weight, which may include the following steps:

[0116] In the first step, a judgment matrix is constructed for the core process termination point, the basic process termination point, and the importance of the termination point to obtain a first judgment matrix, wherein the values in the first judgment matrix may be input by the user.

[0117] The second step is to use the first judgment matrix to generate the core process endpoint weights, the basic process endpoint weights, and the endpoint importance weights. The eigenvectors of the first judgment matrix can be calculated using the analytic hierarchy process (AHP) method, and the values in the eigenvectors of the first judgment matrix are used as the core process endpoint weights, the basic process endpoint weights, and the endpoint importance weights, respectively.

[0118] Therefore, the weights of the core process endpoints, the weights of the basic process endpoints, and the weights of the importance of the endpoints are comprehensively determined through the analytic hierarchy process (AHP) by decomposition, comparison, and judgment. This, to a certain extent, avoids the influence of subjective factors when determining weights.

[0119] Step 308 : Using the core process weight, the basic process termination point weight, and the termination point importance weight, determine the termination point score of each termination point represented by the valid termination point information set to obtain a termination point score set.

[0120] In some embodiments, the execution entity may use the core process weight, the basic process termination point weight, and the termination point importance weight to determine the termination point score of each termination point represented by each valid termination point information in the valid termination point information set to obtain a termination point score set.

[0121] In some optional implementations of some embodiments, the execution entity may further determine the sum of the weights corresponding to the valid termination point information among the core process termination point weight, the basic process termination point weight, and the termination point importance weight as the termination point score of the termination point represented by the valid termination point information. The weight corresponding to the valid termination point information may be the termination point importance weight and the weight of the basic process termination point weight or the termination point importance weight that matches the termination point type information included in the valid termination point information.

[0122] Step 309 : Determine the termination point weight of the termination point represented by each valid termination point information in the valid termination point information set according to the termination point score set, and obtain a termination point weight set.

[0123] In some embodiments, the execution entity may use the ratio of each termination point score in the termination point score set to the sum of all termination point scores in the termination point score set as the termination point weight of the termination point to obtain a termination point weight set.

[0124] In some optional implementations of some embodiments, the execution entity determines, based on the termination point score set, the termination point weight of the termination point represented by each valid termination point information in the valid termination point information set to obtain the termination point weight set, which may include the following steps:

[0125] In the first step, a second judgment matrix is constructed based on the above-mentioned set of endpoint scores, wherein the ratio of each of the endpoint scores in the above-mentioned set of endpoint scores can be used as the value in the above-mentioned second judgment matrix.

[0126] In the second step, the termination point weights of the termination points represented by each valid termination point information in the valid termination point information set are determined using the second judgment matrix to obtain a termination point weight set. The eigenvectors of the second judgment matrix can be solved using the analytic hierarchy process (AHP) method, and the values in the eigenvectors of the second judgment matrix are used as the termination point weights of the termination points represented by each valid termination point information in the valid termination point information set.

[0127] Therefore, the weight of the end point is determined comprehensively by the analytic hierarchy process in the way of decomposition, comparison and judgment, which avoids the influence of subjective factors when determining the weight to a certain extent.

[0128] Step 310: Generate an overall risk factor based on the endpoint score set and the endpoint weight set.

[0129] In some embodiments, the execution entity may generate an overall risk coefficient based on the termination point score set and the termination point weight set.

[0130] In some optional implementations of some embodiments, the execution entity may determine the overall risk coefficient as the product of a horizontal quantity composed of the individual endpoint scores in the endpoint score set and a vertical quantity composed of the individual endpoint weights in the endpoint weight set. The endpoint weights and endpoint scores at the same dimension in the vertical quantity composed of the individual endpoint weights and the horizontal quantity composed of the individual endpoint scores correspond to the same valid endpoint information.

[0131] From this, the endpoint score and endpoint weight can be combined to determine the overall risk of the software or program.

[0132] Step 311 , in response to determining that there is a failure risk rate greater than a failure risk rate threshold, a failure risk growth rate greater than a failure risk growth rate threshold, or an overall risk coefficient greater than an overall risk coefficient threshold, performing an alarm operation.

[0133] In some embodiments, the specific implementation of step 311 and the technical effects thereof can be referred to Figure 2 Step 205 in the corresponding embodiments will not be described again here.

[0134] from Figure 3 It can be seen that Figure 2 Compared with the description of some corresponding embodiments, Figure 3 Flow 300 of the fault diagnosis and alarm method in some corresponding embodiments embodies the steps of using information entropy to filter valid endpoint information from the endpoint information set, and the step of using a judgment matrix to determine the overall risk factor. Thus, the solutions described in these embodiments can accurately determine the extent of abnormal conditions that occur during program or code execution, thereby providing more accurate alarms.
