Embodiment 1

[0078] Such as figure 1 As shown, the present invention provides a GRA-based server fault diagnosis rule screening method, comprising the steps of:

[0079] S1. traverse each fault in the server fault record and each rule in the rule database set, calculate the fault matching rate of each rule, and obtain the fault matching rate sequence of each rule in the rule database set;

[0080] S2. Count the faults successfully matched by each rule, and count the number of faults corresponding to each fault level, and then remove the number of faults corresponding to low fault levels through the method of ignoring the minimum value between partitions, and then according to the preset weight of each fault level and the The number of faults in the fault level, calculate the severity of each rule matching fault, and obtain the fault severity sequence of each rule in the rule database set;

[0081] S3. Use the GRA algorithm to calculate the correlation degree of any two rules in the rule d...

[0084] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention provides a GRA-based server fault diagnosis rule screening method, comprising the steps of:

[0085] S1. traverse each fault in the server fault record and each rule in the rule database set, calculate the fault matching rate of each rule, and obtain the fault matching rate sequence of each rule in the rule database set; the specific steps are as follows:

[0086] S11. Obtain the fault state database of server fault records and the rule base data set for server fault diagnosis; each fault in the fault state database includes several fault states, and each rule in the rule database set includes several indicators, and the fault state of the fault The number is equal to the index number of the rule;

[0087] S12. A rule is concentrated in the positioning rule database, and the deviation rate of each fault state data of each fault and the corresponding index data of the p...

Embodiment 3

[0134] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention provides a GRA-based server fault diagnosis rule screening method, comprising the steps of:

[0135] S1. traverse each fault in the server fault record and each rule in the rule database set, calculate the fault matching rate of each rule, and obtain the fault matching rate sequence of each rule in the rule database set; the specific steps are as follows:

[0136] S11. Obtain the fault state database of server fault records and the rule base data set for server fault diagnosis; each fault in the fault state database includes several fault states, and each rule in the rule database set includes several indicators, and the fault state of the fault The number is equal to the index number of the rule; the rule base data set comes from the real record when the server fails, which ensures the authenticity and reliability of the data source;

[0137] S12. A rule is concentrat...

Abstract

The invention provides a server fault diagnosis rule screening method based on GRA, and the method comprises the following steps: traversing each fault and each rule, calculating a rule fault matching rate, and obtaining a fault matching rate sequence; removing the number of faults of low fault levels through an inter-partition neglect minimum algorithm, and calculating the severity of rule matching faults according to the preset weight of each fault level and the corresponding number of faults to obtain a fault severity sequence; calculating the correlation degree of any two rules through a GRA algorithm, calculating the correlation degree of each rule and the rule database set, obtaining a correlation degree sequence, and then carrying out steering to obtain a steering correlation degree sequence; calculating weight values of the fault matching rate sequence, the fault severity sequence and the steering similarity sequence through a reciprocal variance algorithm, obtaining a good and bad value sequence through weighted summation, and setting priorities for all rules according to good and bad values. According to the method, the rule with high quality value is preferentially used for diagnosis, so that the redundancy of repeated diagnosis is reduced, and the diagnosis speed is increased.

Description

technical field [0001] The invention belongs to the technical field of server fault diagnosis, and in particular relates to a GRA-based screening method for server fault diagnosis rules. Background technique [0002] GRA is the abbreviation of Gray Relation Analysis, gray relational analysis. [0003] ISCDS, is a server log diagnostic tool. [0004] With the increasing demand for big data processing and the urgent need for faster and more accurate data processing methods, the requirements for the stability and security of the data center are getting higher and higher, and the stability and security of the data center are closely related to each related to the server. At present, the way to ensure the safety and stability of the server is to make a diagnosis by applying the fault diagnosis rules to the various performance indicators of the server. Too much data in the rule base and a certain degree of similarity in the rules make the diagnosis process cumbersome and time-c...
