As used herein, the term "and/or" includes all or any element and all combinations of one or more of the associated listed items.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The terms referred to in this application will first be introduced and explained:
a Frequent Pattern tree (FP-tree) is a tree structure satisfying the following conditions: (1) it consists of a root node (null), item prefix subtrees (as children), and a frequent item header table. (2) Each node in the item prefix subtree includes three domains: item _ name, count, and node _ link, where: item _ name records the identification of the item represented by the node; the count records the number of transactions of the sub-path reaching the node; the node _ link is used to connect the next node with the same identifier in the tree, and if the next node with the same identifier does not exist, the value is "null". (3) The entries of the frequent entry header table include a frequent entry identification field: item _ name and a head pointer to the first frequent item node in the tree with the item identification: head of node _ link.
The general procedure for FP-growth is as follows:
1: firstly, scanning the data set once to obtain an item set with frequent items of 1, defining minimum support (the minimum number of times of occurrence of items), deleting the items smaller than the minimum support, and then arranging the items in the original data set according to the descending order of the item set.
2: the second scan, creates an entry header table (descending order from top to bottom), and a FP-tree.
A CART (Classification And Regression Tree), called a CART Tree for short, is formed by a binary recursive partitioning method, a current sample set is divided into two sub-sample sets, so that the generated non-leaf sub-nodes all have two branches, therefore, a decision Tree generated by the CART algorithm is a binary Tree with a simple structure, the non-leaf nodes of the CART Tree are generally attributes or judgment conditions, And the leaf nodes are item frequent item sets corresponding to (or not belonging to) the attributes
The system stability refers to a certain stable state of a system element under external influence, and colloquially refers to the ability of ensuring that the system can still provide continuous and reliable service in the process of operation, operation and maintenance, namely in the face of various extreme situations or emergencies. With the development of the internet, the requirements of each large internet company on the stability and reliability of the service are higher and higher. In the field of software systems, a common index is the service availability time ratio, the higher the ratio is, the higher the system stability is, if we take the data of a whole year, the common 4 9 (99.99%) means that the service provided by our system is only 52 minutes long in the unavailable time of the whole year! Therefore, the importance of the system stability analysis can be seen.
There is no reliable system in the world, and machines, programs and networks may have problems in operation, which leads to system abnormality and loss of money and reputation, so the objective of ensuring system stability is to reduce loss, and it is expected to shorten the MTTR (mean time to repair) when abnormality occurs by finding, locating and solving problems. At present, a plurality of relatively mature system stability monitoring systems exist, and the system stability monitoring systems mainly monitor index information such as hardware, systems, applications, networks and the like, constantly monitor the systems in real time, feed back the current states (normal, abnormal and fault) of the systems in real time, and ensure the reliability, safety and sustainable and stable operation of the systems.
The present application provides a fault repairing method, apparatus, electronic device and computer readable storage medium, which aim to solve the above technical problems in the prior art.

step S101, obtaining fault data, wherein the fault data comprises at least one target index information with faults.
Index information in the embodiments of the present application refers to any data or data combination used for determining system stability, including but not limited to environment information, host information, system information, application information, and network information, and specifically, the index information may be CPU temperature, physical disk, motherboard temperature, disk array, memory usage, disk read-write throughput, process port, database data, network information, and the like.
The target index information in the embodiment of the present application refers to the index information that has a fault, that is, the index information is faulty and is abnormal. Each index information may be compared with preset index information (or a preset index information threshold), when the index information is not equal to the preset index information or the index information is higher than the preset index information threshold, it may be determined that the index information is target index information with a fault, for example, the CPU temperature at a certain time exceeds 60 degrees to determine that the CPU temperature is abnormal, that is, the CPU at the time is the target index information with a fault, for example, a network signal is abnormal at a certain time, that is, the network signal is the target index information with a fault, and other index information may determine whether the index information is the target index information with a fault by comparing with the preset index information threshold, which is not illustrated in detail herein.
The fault data in the embodiment of the present application includes at least one target index information where a fault occurs, and the fault data is a fault detected at any time point.
Step S102, determining associated index information corresponding to target index information from a preset and constructed frequent pattern FP tree, wherein the FP tree comprises the associated relation of at least two index information.
The associated index information of the embodiment of the application refers to index information which has a corresponding relation with target index information, the corresponding relation refers to the possibility that the associated index information fails after the target index information with the failure appears, and by finding out the index information which has the corresponding relation with the target index information, the potential risk can be effectively excavated, and the impending failure can be predicted.
The FP tree of the embodiment of the application is constructed in advance, the FP tree comprises the association relation of each index information, and the association index information corresponding to the target index information can be determined by traversing the FP tree.
And step S103, restoring the target index information and the associated index information.
After the associated index information corresponding to the target index information is determined, the target index information is repaired, and meanwhile, the associated index information is also repaired in advance, so that other faults are avoided, or the faults can be repaired in time.
According to the method and the device, fault data are obtained, wherein the fault data comprise at least one piece of target index information with faults; determining associated index information corresponding to target index information from a preset constructed frequent pattern FP tree, wherein the FP tree comprises the associated relation of at least two pieces of index information; the target index information and the associated index information are repaired, and the association between faults can be effectively mined, so that the potential fault information is timely mined, and the stability of the system is better ensured.
An embodiment of the present application provides a possible implementation manner, and as shown in fig. 2, an exemplary diagram of a building process of a FP-tree is shown, where a building method of the FP-tree includes:
step S201, a fault sample set is collected, wherein the fault sample set comprises at least one fault sample, and the fault sample comprises at least one fault index information.
Index information in the embodiments of the present application refers to any data or data combination used for determining system stability, including but not limited to environment information, host information, system information, application information, and network information, and specifically, the index information may be CPU temperature, physical disk, motherboard temperature, disk array, memory usage, disk read-write throughput, process port, database data, network information, and the like.
The fault sample set comprises a plurality of fault samples, and each fault sample comprises at least one fault index information.
The embodiment of the application does not limit how to acquire the sample data, for example, firstly, index information samples are acquired, each index information sample comprises a plurality of pieces of information, each index information is compared with preset index information, and if the index information is normal, the index information is removed from the sample, so that only the index information of a fault is left in the sample, and at this time, the index information sample set is a fault sample set.
Step S202, scanning a fault sample set, counting the occurrence frequency of each fault index information, eliminating fault index information with the occurrence frequency smaller than the preset occurrence frequency, and putting the residual fault index information and the corresponding occurrence frequency into an FP tree head pointer table according to a descending order arrangement rule.
The method comprises the steps of firstly scanning the whole fault sample set, determining the occurrence frequency of each fault in the fault sample set, wherein the occurrence frequency of the index information of the fault is also called the support degree of the index information of the fault, if the occurrence frequency of certain fault index information is less than the preset occurrence frequency, the fault index information is not frequently fault and not frequently fault, the fault index information can be removed from the fault sample set, and each fault sample does not comprise the fault index information.
Specifically, assume that there are 9 failure samples in the failure sample set, and each of the samples is:
failure sample 1: A. b, E, F, respectively;
failure sample 2: B. d;
failure sample 3: B. c;
failure sample 4: A. b, D, respectively;
failure sample 5: A. c;
failure sample 6: B. c;
failure sample 7: A. c;
failure sample 8: A. b, C, E, respectively;
failure sample 9: A. b, C, respectively;
wherein A, B, C, D, E and F are different types of index information of fault
Scanning the fault sample set for the first time, and counting the occurrence frequency of each faulted index information, wherein the occurrence frequency of each faulted index information is as follows:
a: 6 times; b: 7 times; c: 6 times; d:2 times; e:2 times; f: 1 time;
defining the minimum occurrence frequency of the index information with faults as 2, and reordering the index information with faults according to a descending order rule, wherein the ordering result is as follows: b: 7 times; a: 6 times; c: 6 times; d:2 times; e:2 times, based on the times, a head pointer table of the FP-tree can be created, the head pointer table is shown in table 1:
Figure BDA0003229517960000101
Figure BDA0003229517960000111
TABLE 1
Meanwhile, the arrangement sequence of the index information with faults in the fault sample can be sorted according to the occurrence frequency of each index information with faults, and the sorted fault sample is as follows:
failure sample 1: B. a, E, respectively;
failure sample 2: B. d;
failure sample 3: B. c;
failure sample 4: B. a, D, respectively;
failure sample 5: A. c;
failure sample 6: B. c;
failure sample 7: A. c;
failure sample 8: B. a, C, E, respectively;
failure sample 9: B. a, C, respectively;
according to the embodiment of the application, after the fault sample is scanned for the first time, the occurrence frequency of each piece of fault index information is obtained, and the head pointer table of the FP tree is established based on the occurrence frequency of each piece of fault index information.
Step S203, creating a root node of the FP tree, sequentially scanning each fault sample, sequentially linking the indicator information with the fault in the fault sample to the root node, if the node corresponding to the indicator information with the fault in the path where the fault sample is located already exists, adding one to the count of the node, and if the node corresponding to the indicator information with the fault does not exist, adding a node corresponding to the indicator information with the fault in the path.
In the above steps, after the faulty index information with the frequency less than the preset frequency is removed from the faulty samples, the arrangement sequence of the faulty index information in each faulty sample is sorted to obtain sorted faulty samples, and the arrangement sequence of the faulty index information in the sorted faulty samples is arranged according to the frequency of occurrence of each faulty index information in the whole faulty sample set.
In the embodiment of the application, after a head pointer table of an FP tree is created, the FP tree is created, a root node of the FP tree is created first, the root node of the FP tree is empty, each fault sample is scanned in sequence, the faulty index information in the fault sample is connected to the root node, if a node corresponding to the faulty index information in a path where the fault sample is located already exists, the count of the node where the node is located is added, if a node corresponding to the faulty index information does not exist, the node corresponding to the faulty index information is newly added in the path until the entire FP tree is created, the node corresponding to the node of the FP tree is the faulty index information and the count (frequency of occurrence) of the faulty index information in the path, if the fault sample is located in the path and the node corresponding to the faulty index information exists, when the faulty index information is scanned again, and if the node corresponding to the index information with the fault does not exist in the path where the fault sample is located, the node corresponding to the index information with the fault is newly added to the path.
In addition, pointers corresponding to each failed index information in the head pointer table are required to point to nodes corresponding to the failed index information in the FP tree.
Specifically, continuing with the example, as shown in fig. 3a, which exemplarily shows a schematic diagram after connecting the fault sample 1 to the root node of the FP-tree, the order of the failed indicator information in the head pointer table is ordered according to the frequency of occurrence of each failed indicator information, the failed indicator information in the fault sample 1 has B, A and E, the failed indicator information B in the head pointer table points to the node B in the FP-tree, the failed indicator information a in the head pointer table points to the node a in the FP-tree, and the failed indicator information E in the head pointer table points to the node E in the FP-tree.
Continuing the above example, as shown in fig. 3B, the schematic diagram after the fault sample 2 is linked to the root node of the FP tree is exemplarily shown, where the index information with the fault in the fault sample 2 has B and D, and is also the first in the row of the index information with the fault B, the count of the node B is directly increased by one, and the node corresponding to the index information D with the fault does not exist in the generated FP tree, and the node corresponding to the index information D with the fault needs to be newly added in sequence.
Continuing the above example, as shown in fig. 3c, the FP tree is generated after the fault samples 3, 4, 5, 6, 7, 8, and 9 are sequentially connected to the FP tree, each path of the FP tree is a sample, as can be seen from the FP tree, 7 fault samples include the indicator information B that a fault occurs, and the first place of the indicator information a that a fault occurs in 2 fault samples is the first place of the indicator information B that a fault occurs in 7 fault samples.
The embodiment of the present application provides a possible implementation manner, in which association index information having a correspondence with target index information is determined from a preset constructed FP tree, including:
traversing the FP tree, and mining a frequent item set corresponding to target index information; the frequent item set comprises at least one candidate index information which has a corresponding relation with the target index information;
and determining associated index information corresponding to the target index information from the candidate index information based on a preset rule.
The candidate index information exists in the frequent item set, and other index information except the target index information in the frequent item set is the candidate index information.
In the embodiment of the application, the FP trees corresponding to the fault sample set are constructed to determine the association relationship between each piece of faulty index information, and after the fault data is obtained, the association index information corresponding to the target index information where the fault occurs in the fault data is determined by traversing the FP trees, and the specific method is as follows:
the conditional mode is based on a path set taking the searched element item as the end, each path is actually a prefix path, and the frequent item set refers to frequent items: frequently occurring elements/items in multiple collections are frequent items
Frequent item set: there are a series of sets, these sets have some identical elements, the elements with high frequency of occurrence in the set at the same time form a subset, satisfy certain threshold condition, it is a frequent item set.
A very large frequent itemset: the frequent item set with the most elements, i.e. any superset of the frequent item set, is a non-frequent item set. Frequent items, also called frequent 1 item set, with 1 element in the subset, frequent 2 item set, with 2 elements in the subset, … …, frequent n item set, with n elements in the subset, n being a positive integer.
Assuming that target index information with a fault is E, starting with a node where the node E is located, traversing the whole FP tree from bottom to top to obtain a conditional pattern base { (B A:1), (B A C:1) }, constructing a conditional FP sub-tree corresponding to the conditional pattern base of the index information E with the fault as shown in FIG. 4a, then recursively calling the conditional FP sub-tree, enumerating all combinations of { B:2, A:2, C:1}, and then merging the conditional FP sub-tree with E to obtain a frequent item set { BE:2}, { AE:2} and { BAE:2} with a support degree corresponding to the index information E with the fault larger than 2, wherein { B E:2} and { A E:2} are frequent 2 sets of E, and { B A E:2} is frequent 3 sets of E.
Assuming that the target index information with a fault is C, starting with the node where the node C is located, traversing the entire FP sub-tree from bottom to top to obtain a conditional schema base { (BA:2), (B:2), (a:2) }, and constructing the FP sub-tree corresponding to the conditional schema base of C, as shown in fig. 4B1, where the FP sub-tree corresponding to the conditional schema base of the index information with a fault C is still a multi-path tree, and a set of frequent item sets { B C:4} and { A C:4} is obtained by merging each item in the head pointers of the conditional FP sub-trees corresponding to the conditional schema bases of C and C, but this set of frequent item sets is not all frequent item sets with C suffixes, and further requires to recursively invoke the conditional FP of C, the frequent item sets are { a, B }, and the conditional schema bases of { a, C } are { B:2, which generates a conditional FP sub-tree as shown in fig. 4b 2. This is a one-path conditional FP subtree in which B is merged with the pattern suffix { a, C } to obtain the pattern { ABC: 2}. Theoretically, a mode set with { B, C } as the mode suffix should also be calculated, but the conditional mode base of { B, C } is null, the recursive call ends, and all the frequent item sets with the final mode suffix I3 with a support degree greater than 2 are: { B C:4}, { A C:4}, and { AB C:2}, where { B C:4} and { A C:4} are frequent 2-item sets, and { AB C:2} is a frequent 3-item set.
For B, the corresponding conditional mode base is null, mining is not needed, the mining method for frequent item sets of other nodes is the same as the above method, the embodiments of the present application are not described one by one, and finally the frequent item sets corresponding to each target index information are shown in table 2:
node (index information of fault) Frequent item set (frequent mode)
E {B E:2},{A E:2},{B A E:2}
D {B D:2}
C {B C:4},{AC:4},{AC:2}
A {B A:4}
TABLE 2
According to the method and the device, the frequent item sets corresponding to the target index information are determined by traversing the pre-constructed FP tree, the frequent item sets comprise the frequent item set 2, the frequent item set 3, the frequent item set n, wherein n is a positive integer greater than 1, the elements in the frequent item sets have an incidence relation, and the candidate index information corresponding to the target index information can be determined by determining the frequent item sets corresponding to the target index information.
In the embodiment of the application, the candidate index information and the target index information in the frequent item set have a corresponding relationship, the corresponding relationship is an association relationship, and the occurrence of the target index information may cause the occurrence of the candidate index information, that is, one fault may cause the occurrence of another fault, and does not necessarily cause the occurrence of another fault, and the association index information needs to be further determined from the candidate index information based on a preset rule, so that the subsequent content is detailed.
The embodiment of the present application provides a possible implementation manner, in which association index information having a correspondence with target index information is determined from candidate index information based on a preset rule, including:
calculating the confidence coefficient between the target index information and the candidate index information according to a preset confidence coefficient calculation method;
and determining associated index information corresponding to the target index information from the candidate target information according to the confidence degree.
The confidence level, also called reliability, or confidence level, confidence coefficient, i.e. when the sampling estimates the overall parameter, the conclusion is always uncertain due to the randomness of the sample, the span of the confidence interval is a positive function of the confidence level, i.e. the greater the confidence level required, the wider the confidence interval must be obtained, which correspondingly reduces the accuracy of the estimation.
In the embodiment of the present application, the confidence between the target index information and the candidate index information indicates the possibility of occurrence of the candidate index information due to the target index event, and the preset confidence calculation method corresponds to a calculation formula:
Figure BDA0003229517960000151
it should be noted that the target index information herein does not refer to a single index information, but may refer to a combination of a plurality of index information, the support degree of the frequent item set refers to the number of occurrences (frequency) of the frequent item set in the failure sample set, and the support degree of the target index information refers to the number of occurrences of the target index information in the failure sample set.
Specifically, continuing the above example, if the combination of the target index information a and B includes a frequent item set of a and B having { B a E:2}, where the degree of support of { B a E:2} is 2 and the degree of support of the combination of a and B is 3, the confidence between the target index information and the candidate index information is 2/3, that is, when the target index information is a combination of a and B (the combination of a and B is subsequently represented by AE), the probability of causing the index information E to malfunction is 2/3.
Continuing the example, if the target index information is B, the frequent 2 item set of B has { B E:2}, { B D:2}, { B C:4} and { B A:4}, and the support degree of B is 7, it is sequentially calculated that when the target index information B fails, the probability of causing failure of A, C, D and E is 2/7, 2/7, 4/7 and 4/7, respectively, and the frequent 3 item set of B has { B a E:2}, and it can be calculated that after the target index information B fails, the probability of causing failure of a and E at the same time is 2/7.
According to the method and the device, after the confidence degree between the target index information and the candidate index information is calculated, the associated index information corresponding to the target index information is determined from the candidate index information according to the confidence degree between the target index information and the candidate index information.

Such a decision tree is equivalent to recursively bisecting each feature, dividing the input space, i.e., the feature space, into a finite number of cells, and determining a predicted probability distribution over the cells, i.e., the conditional probability distribution that is output under the given conditions of the input.
In the embodiment of the present application, a non-leaf node of a cart tree is a determination condition, an edge of the cart tree indicates a determination result, a leaf node indicates candidate index information belonging to the determination result, and the leaf node also corresponds to one category.
