The expansion for hindering type, improves the ease for use and scalability of journal analyzer.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Other embodiments are obtained according to these attached drawings.
Fig. 1 is the logical schematic that the embodiment of log analysis is realized using the method for the present invention；
Fig. 2 is a kind of hardware structural diagram of server log analytical equipment according to an embodiment of the present invention.
Specific embodiment
The following describe embodiment of the disclosure.It should be appreciated, however, that the disclosed embodiments are only example, and
Other embodiments can take various alternative forms.The drawings are not necessarily drawn to scale；Certain functions may be exaggerated or minimum
Change the details to show particular elements.Therefore, specific structure and function details disclosed herein are not necessarily to be construed as restrictive,
And it is merely possible to for instructing those skilled in the art to use representative basis of the invention in various ways.As this field is general
It is logical the skilled person will understand that, the various features with reference to shown or described by any one attached drawing can with it is one or more other
Feature shown in the drawings is combined to produce the embodiment for not being explicitly illustrated or describing.The group of shown feature is combined into typical case
Provide representative embodiment.However, the various combinations and modification of the feature consistent with the introduction of the disclosure are for certain spies
Fixed application or embodiment may be desired.
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
The embodiment of the present invention is further described in attached drawing.
In daily programming, often there are some functions not need to be compiled or can use in multiple files (such as data
The Standard Tasks such as library input/output operations or screen control function).These functions can be compiled in advance, then by it
Be placed in some special object code files, these object code files are known as library.Function in library file can be with
Linked by linker and application program, thus need not every time exploitation program when all to these general functions into
Row compiles.Dynamic base is a kind of when the compiled program finished starts starting operation, is just loaded to call wherein letter
Several libraries, loading method are completely different with static library.Under linux system, dynamic base is usually with .so (share object) knot
Tail, under Windows system, dynamic base is often ended up with .dll.
Based on above-mentioned purpose, the embodiment of the invention provides a kind of log analysis methods, as shown in Figure 1, including following step
It is rapid:
Establish and safeguard that the keyword rule base for accident analysis, every rule therein include failure title, key
Word, Log Names and diagnostic logic；
Log is obtained, and the keyword database according to the log access is to traverse the rule, comprising:
The Log Names for the log that will acquire are matched with the Log Names in the rule；
After successful match, the content of the log is read to search whether to deposit the keyword for including in the rule；With
And
After finding the keyword, call the code of the diagnostic logic in the rule to judge whether failure is true.
Wherein, if the failure is set up, corresponding failure title in the rule is exported.
The present invention is firstly the need of establishing and safeguard the keyword rule base for log analysis, keyword rule base therein
It mainly include that failure title, failure keyword, Log Names, diagnostic logic show two groups of rule A as shown in table 1 in table 1
And B.Wherein diagnostic logic realizes the analytic process of every failure, is certain keyword occur to certain log to judge the failure later
Whether true decision logic, be customized by the user and write.In some embodiments, user can be by increasing keyword and modification
Corresponding diagnostic logic updates the keyword rule base.User is to expand detectable failure kind by log analysis
Class need to only expand keyword rule base.
| Failure title | Keyword | Log Names | Diagnostic logic |
| A | [A1,A2,…] | logA | analysisA |
| B | [B1,B2,…] | logB | analysisB |
Table 1
In some embodiments, the realization of diagnostic logic can be dynamic library.Calling of the main program to diagnostic logic
The method that dynamically load dynamic link library can be used, that is, use dlopen, dlsym, dlclose function.In some embodiments
In, the diagnostic logic can be shell script, shell-command etc., such as python script, shell script etc..
According to one embodiment of present invention, according to architecture design above, failure keyword rule base is filled, is used
The method of dynamic library realizes diagnostic logic, realizes log analysis tool, carries out fault diagnosis to server.Firstly, filling
Hard disk media false judgment rule is added, as shown in table 2 in keyword rule base；Then, diagnostic logic libdisk.so is write,
The diagnostic logic is by the size of data to keyword heel to determine whether failure, that is, realize to log
The numerical values recited of " Media Error Count " the keyword heel occurred in MegaCliLDPDInfo.txt judges, if numerical value
Greater than 0, then it represents that media error occurs for hard disk, if being equal to 0, then it represents that there is no media errors for hard disk；Running log analysis
Main program, main program realizes the calling to diagnostic logic by the method for dynamically load dynamic link library；If diagnostic logic
It runs succeeded, then illustrates that hard disk media mistake has occurred in server, then export failure title.
| Failure title | Keyword | Log Names | Diagnostic logic |
| Hard disk media mistake | Media Error Count | MegaCliLDPDInfo.txt | libdisk.so |
Table 2
Technically in feasible situation, it can be combined with each other above in relation to technical characteristic cited by different embodiments,
Or change, add and omit etc., to form the additional embodiment in the scope of the invention.
