AI Technical Summary

Problems solved by technology

Although the neural network has improved the efficiency and accuracy of server fault diagnosis, the neural network diagnosis method cannot be explained, and the fault phenomenon cannot be explained and analyzed from the root cause of the problem.
[0004] To sum up, first of all, the existing fault diagnosis methods have the problem of insufficient information sources. With the help of multimeters, oscilloscopes and other means, they rely too much on the experience and quality of diagnostic personnel, which has certain blindness and limitations; The diagnosis process does not make full use of the fault data flow, it is difficult to accumulate diagnosis experience, the diagnosis efficiency is low, and the efficient and reliable operation of the server cannot be guaranteed
In addition, the existing fault diagnosis results have problems such as uncertainty and poor interpretability, which cannot guarantee that the fault will be eliminated from the root cause, causing quality risks in server operation

Embodiment Construction

[0050] The invention discloses an automatic detection method for server faults based on a decision tree, which is combined with an expert system and an IPMI (Intelligent Platform Management Interface) management unit to generate a historical data set; through the IPMI management unit, the server operation status data at the time of failure is obtained, that is, the abnormal data flow , extract new fault feature vectors according to the abnormal data flow, and form the fault data set with the relationship between the new feature vector and the fault cause, and train it into a self-diagnosis decision tree model; when the server fails during operation, extract the corresponding fault features Vector, the self-diagnosis decision tree model automatically judges the fault type, cause and treatment method and notifies the technicians. After the fault is cleared, the fault feature vector and fault cause relationship are added to the historical fault set to complete the update, and the s...

Abstract

The invention discloses an automatic detection system and detection method for server faults based on a decision tree, combined with an expert system and an IPMI management unit to generate a historical data set; through the IPMI management unit to obtain the server operation status data at the time of failure, that is, the abnormal data flow, according to The abnormal data flow extracts new fault feature vectors, and the fault data set is composed of new feature vectors and fault cause relationship pairs, and is trained into a self-diagnosis decision tree model; when a fault occurs during server operation, the corresponding fault feature vector is extracted, The self-diagnosis decision tree model automatically judges the fault type, cause and treatment method and notifies the technicians. After the fault is cleared, the fault feature vector and fault cause relationship are added to the historical fault set to complete the update, and the self-diagnosis fault tree model is updated. , so with the continuous improvement of the historical fault set, the fault diagnosis system will be more accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of server management, and in particular relates to a server fault automatic detection system and detection method based on a decision tree. Background technique [0002] As the complexity of the server system becomes higher and higher, the design of supporting software and hardware becomes more and more complex, and the corresponding hidden dangers of failure also increase. When the server system fails, if the fault diagnosis and targeted maintenance are not carried out in time, it will affect the normal operation of the server, and even cause serious consequences such as server downtime. [0003] Existing server fault diagnosis methods include: comparison diagnosis method, fault tree diagnosis method, simulation experiment diagnosis method, expert system diagnosis method, neural network diagnosis method and so on. The comparative diagnosis method collects and stores data of various information of various s...
