Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
Before method, apparatus, storage medium and the electronic equipment that the log for introducing disclosure offer is extracted, first to this
Application scenarios involved by each embodiment are disclosed to be introduced.The application scenarios are to carry out contents extraction to log.Wherein, log
Source can there are many, can be what kinds of platform was generated when executing multiple business, the log exported by unified port,
It include various types of multiple log events in log, it can be understood as a record in log, i.e., it can be only in log
An individual for vertical description once-through operation or an implementing result, is the basic unit of contents extraction.Log event for example may be used
To include: log event of fire wall, interchanger log event, system execution journal event, business diary event, user's operation day
Will event, database journal event etc..For various types of log events, log template set, log can be previously provided with
Include the corresponding log template of each type of log event in template set, in the log event for extracting the type in
Hold.Since the scale of operation system gradually increases, the type of log event is very much (several hundred kinds), therefore corresponding log template set
In also contain a large amount of log template (such as: JSON template, XML template, date template, KV template, CSV template etc.), such as
Fruit successively matches each log event in log to be extracted with each log template in log template set, calculation amount
All very high with complexity, the efficiency of contents extraction is too low, is difficult to carry out practical application.
Fig. 1 is the flow chart for the method that a kind of log shown according to an exemplary embodiment is extracted, as shown in Figure 1, should
Method includes:
Step 101, sample log is determined from log to be extracted, sample log includes multiple log events.
For example, due to containing a large amount of log event in log to be extracted, and it is difficult to predefine a large amount of
It include the log event of which type in log event, it accordingly also can not be from log template a large amount of in log template set
Selection is suitble to the log template of log to be extracted, carries out contents extraction to log to be extracted.It therefore, can be first from day to be extracted
Determination includes the sample log of multiple log events in will.The quantity for the log event for including in sample log will be far smaller than
The quantity for the log event for including in log to be extracted, therefore in subsequent processing, effectively reduce calculation amount and complexity.
In the present embodiment, can determine sample log according to pre-set rule, for example, according to time range into
Row selection, or random selection.By taking the time range of log to be extracted is one month as an example, then can choose wherein 24 hours
Inside include multiple log events composition sample log, can also be randomly choosed in log to be extracted preset percentage (such as:
10%) multiple log events form sample log.
Step 102, target journaling event is extracted from multiple log events.
It is exemplary, it, can be from sample log since the quantity for the log event for including in sample log is still more
In extract the target journaling event for being able to reflect log to be extracted, to be further reduced the number of log event to be treated
Amount, is effectively reduced the calculation amount and complexity of subsequent processing.For example, analyzing the difference of each log event in sample log first
Characteristic value, difference characteristic value can be understood as uniqueness of the log event in sample log, that is, reflect the log event with
The difference size between other log events in sample log.Come later further according to the difference characteristic value of each log event true
The event extraction parameter of this log of random sample, event extraction parameter can be understood as the energy that sample log is able to reflect log to be extracted
Power size, it is understood that contain the log event of which type in reflected sample log.Finally according to sample log
Event extraction parameter extracts target journaling event from multiple log events, and target journaling event can be represented wait mention to maximum probability
Take the log event in log.Wherein, target journaling event can be one or more, the quantity of target journaling event compared to
The quantity for the log event for including in sample log will substantially reduce.
Step 103, the determining target journaling template with target journaling event matches, log in preset log template set
It include at least one log template in template set.
Further, after determining target journaling event, at least one log mould that preset log template set includes
In plate, the target journaling template of selection and target journaling event matches.Wherein, target journaling template can be to target journaling event
Carry out correctly contents extraction.The corresponding target journaling template of one target journaling event, while may have multiple target days
Will event corresponds to the same log template, therefore the quantity of target journaling template is less than or equal to the quantity of target journaling event.
The log event in log to be extracted, corresponding target journaling template can be represented to maximum probability due to target journaling event
It can be adapted to maximum probability log to be extracted.
Step 104, contents extraction is carried out to log to be extracted according to target journaling template.
Finally, according to the target journaling template determined in step 103, successively to each log event in log to be extracted
Carry out contents extraction.If target journaling template only one (can be understood as log to be extracted at this time be row text structure it is consistent
Log, the type of each of these log event is identical), then each log event in log to be extracted, all uses mesh
It marks log template and carries out contents extraction.If target journaling template is multiple, then for each log thing in log to be extracted
Part successively determines the matching degree of the log event Yu multiple target journaling templates, and according to the maximum target journaling mould of matching degree
Plate carries out contents extraction to the log event.
In conclusion disclosure determination first from log to be extracted includes the sample log of multiple log events, it
Afterwards from multiple log events extract target journaling event, then it is preset include the log mould of at least one log template
Plate is concentrated, the determining target journaling template with target journaling event matches, finally according to target journaling template to log to be extracted
Carry out contents extraction.Without the decimation rule of the labyrinth design specialized for different logs, reduce the work of developer
Measure, can the log to various structures carry out contents extraction automatically, reduce extraction complexity, improve extraction efficiency and suitable
Use range.
Fig. 2 is the flow chart for the method that another log shown according to an exemplary embodiment is extracted, as shown in Fig. 2,
Step 102 can be realized by following steps:
Step 1021, it for each log event, determines in the log event and multiple log events except the log event
Except each log event diversity factor, and according in the log event and multiple log events in addition to the log event
The diversity factor of each log event determines the difference characteristic value of the log event.
For example, the difference characteristic value that each log event uniqueness is able to reflect in sample log can be first determined,
Wherein, difference characteristic value can be according to each log thing in the log event and multiple log events in addition to the log event
The diversity factor of part determines.For example, can by the log event with it is each in addition to the log event in multiple log events
The diversity factor of log event is summed, and using summed result as the diversity factor characteristic value of the log event.Two log events
Diversity factor may include Difference of content CS, difference in length degree CL, format differences degree CLAt least one of.So log thing
The diversity factor of each log event in part and multiple log events in addition to the log event can sum for a variety of diversity factoies,
Such as: CS+CL+CL。
Wherein, CSIt, can be according to preset character for reflecting difference size of two log events on content of text
String matching algorithm compares the character in two log events successively to obtain, it can be understood as will be in the text of two log events
Hold and successively matched according to preset sequence (such as from left to right), so that it is determined that of the content of text of two log events
With value, to characterize the similarity degree of two log events, matching value is bigger, corresponding CSValue it is lower, matching value is smaller, corresponding
CSValue it is higher.Wherein, string matching algorithm for example may is that KMP (English: Knuth-Morris-Pratt
Algorithm) algorithm, BF (English: Brute Force) algorithm or Horspool algorithm etc..
CLFor reflecting difference size of two log events on text size, in the present embodiment, CLIt may include two
Part, a part are that the content of text of two log events includes the diversity factor C of number of charactersL1, illustratively, CL1Meter can be passed through
Calculating the number of characters that two log events include asks absolute value of the difference to obtain, for example, the number of characters difference that two log events include
It, can be using 30-25=5 as the C of two log events for 25 and 30L1Value.Another part is that two log events are pressed
After being divided into multiple character strings according to spcial character collection (such as: space, ", ", "-", " _ ", "/", tab etc.), character string includes
Number of characters diversity factor CL2, illustratively, CL2It can be obtained by a under type: by two log events according to spcial character
Collection is divided, and N number of character string and M character string are obtained, will be in the first character string and M character string in N number of character string
First character string be compared, if comprising number of characters it is identical, comparison result is denoted as 0, if comprising number of characters
Comparison result is denoted as 1 by difference, successively more N number of character string and M character string.The value that finally comparison result is summed
As CL2Value.It should be noted that if N and M are unequal, the character string that the character string having more and length are 0 can be carried out
Compare, comparison result is 1.
For example, log event A are as follows: " account: 11642205800/ trade date: 2017-06-19 ", log event B are as follows:
" IP:209.160.24.63/ date: 2018-05-21 ".First two log events can be divided according to "/", then day
Will event A is divided into two character strings: " account: 11642205800 ", the number of characters for including is 14, " trade date: 2017-
06-19 ", the number of characters for including are 15.Log event B is also divided into two character strings: " IP:209.160.24.63 " includes
Number of characters be 16, " date: 2018-05-21 ", the number of characters for including be 13.So successively compare log event A and log thing
Character string in part B, " account: 11642205800 " different from the number of characters that " IP:209.160.24.63 " includes, comparison result
It is 1, " trade date: 2017-06-19 " is different from the number of characters that " date: 2018-05-21 " includes, comparison result 1, then
The log event A and corresponding C of log event BL2It sums for two comparison results: 2.
In this way, obtaining CL1And CL2Afterwards, by CL1And CL2Value after being added, as CL。
CMFor reflecting difference size of two log events on text formatting, such as can be first by two log events
Respectively with preset format (time format, " [] " data format, " () " data format, JSON object, JSON array, XML lattice
Formula etc.) it is matched, the matching value for characterizing matching degree is obtained, further according to of two log events and preset format
The C of two log events is determined with valueM, for example, the matching value of two log events and the format of JSON object is respectively
80% and 60%, then two matching values can be asked to absolute value of the difference, i.e., 20% is used as CMValue.
Further, when calculating the diversity factor of two log events, C can be calculated separatelyS、CLAnd CLCorresponding number
Value, since the calculation of different diversity factoies is different, correspondingly, the range of the corresponding numerical value of every species diversity degree obtained may also
Therefore difference is determining CS、CLAnd CLIt later, can be first respectively to CS、CLAnd CLIt is weighted normalization, finally to three kinds
Diversity factor summation, to obtain the diversity factor of two log events.
It should be noted that difference characteristic value is an opposite concept, a log event is described compared to sample
Unique degree of other log events in this log, to illustrate in sample log comprising 20 log events, if wherein a log
Event is type-A, and remaining 19 log events are B type, then each log event in a log event and 19 log events
Diversity factor it is very big, then the corresponding difference characteristic value of a log event is also very high, and b log event in 19 log events, with
Remaining 18 log events are much like, only larger with a log event difference, then the corresponding difference characteristic value of b log event compared with
It is small.
Step 1022, according to the difference characteristic value of each log event, the corresponding event extraction parameter of sample log is determined.
Step 1023, according to event extraction parameter, target journaling event is extracted from multiple log events.
It is exemplary, the difference characteristic value of each log event can be summed, and summed result is normalized, it will be through
Normalized summed result is crossed as the corresponding event extraction parameter of sample log, decimation in time parameter is bigger, can indicate sample
The type for the log event for including in this log is more, needs the target journaling event of selection also more accordingly.
Wherein, in step 1023 extract target journaling event implementation may is that using event extraction parameter as with
The random coefficient (can be understood as operator) of machine selection algorithm extracts target from multiple log events by stochastic selection algorithm
Log event.For example, event extraction parameter is 7, then can be in sample day if in sample log including 100 log events
Every 7 extractions, one log event as target journaling event in will, or using 7 as Pseudo-Random Number calculation
Son generates a pseudo-random sequence, and target journaling event is extracted in sample log according to pseudo-random sequence.
Optionally, the specific implementation of step 103 can be with are as follows:
Step a) is directed to each target journaling event, determines each log in the target journaling event and log template set
The matching degree of template.
Step b) is using the maximum log template of matching degree as the target journaling template with the target journaling event matches.
For example, for each target journaling event, the target journaling event and log template set can successively be calculated
In each log template matching degree.Later, using the maximum log template of matching degree as with the target journaling event matches
Target journaling template, the maximum log template of matching degree can be understood as being best suited for carrying out content to target journaling event mentioning
The log template taken.
The method for calculating the matching degree of target journaling event and each log template, can be according to the log template to mesh
Mark log event and carry out contents extraction, determine matching degree according to the number of characters successfully extracted, matching degree with successfully extract
Number of characters it is directly proportional, i.e., the number of characters successfully extracted is more, and matching degree is higher, and the number of characters successfully extracted is fewer,
It is lower with spending.
It should be noted that the corresponding log template of each target journaling event can be determined according to matching degree, and target
The quantity of log event should be greater than or equal to target journaling template quantity.If each target journaling event corresponding one different
Target journaling template, then the quantity of target journaling event is equal to the quantity of target journaling template, if depositing in target journaling event
The same target journaling template is corresponded at least two target journaling events, then the quantity of target journaling event is greater than target day
The quantity of will template.
In a kind of realization scene, target journaling template may include it is multiple, to log to be extracted in corresponding step 104
The implementation for carrying out contents extraction may include two kinds:
The first implementation: for each log event for including in log to be extracted, the log event and more is determined
The matching degree of each target journaling template in a target journaling template, and according to the maximum target journaling template of matching degree to the day
Will event carries out contents extraction.
Second of implementation: for each log event for including in log to be extracted, the log event and more is determined
The matching degree of each target journaling template in a target journaling template, if the maximum value in matching degree is greater than or equal to matching degree threshold
Value then carries out contents extraction to the log event according to the maximum target journaling template of matching degree.
10 target journaling templates to be determined in step 103, the first log event is any day in log to be extracted
For will event.The matching degree for successively determining the first log event and 10 target journaling templates obtains corresponding 10 matchings
Degree.Wherein, the method for calculating the matching degree of the first log event and each target journaling template, can be according to the target journaling
Template carries out contents extraction to the first log event, and matching degree is determined according to the number of characters successfully extracted, is successfully extracted
Number of characters it is more, indicate that the target journaling template and the matching degree of the first log event are higher, the number of characters successfully extracted
It is fewer, indicate that the target journaling template is lower with the matching degree of the first log event.
In the first implementation, directly the first log event is carried out according to the maximum target journaling template of matching degree
Contents extraction.In the second implementation, first the maximum value in matching degree can be compared with matching degree threshold value, if
With matching degree threshold value is less than to maximum value in degree, then indicating each mesh in the first log event and 10 target journaling templates
The matching degree for marking log template is not high, and it is lower to carry out contents extraction accuracy to the first log event with target journaling template.
The matching degree that can so determine each log template in the first log and log template set again, according in log template set
Contents extraction is carried out to the first log event with maximum log template is spent, is further ensured that the accuracy of contents extraction.If
It is greater than or equal to matching degree threshold value with the maximum value in degree, then indicating that the first log event is looked in 10 target journaling templates
Most matched target journaling template is arrived, then carrying out content to the log event according to the maximum target journaling template of matching degree
It extracts.
Wherein, matching degree threshold value can be determination based on experience value, can also be determined according to target journaling template.Example
Such as, 10 target journaling templates have been determined according to 15 target journaling events in step 103.Further, it can also record
Each target journaling event matching degree with 10 target journaling templates respectively in 15 target journaling events.At step 104,
The matching degree for first determining the first log event and 10 target journaling templates, obtains corresponding 10 matching degrees, wherein matching degree
Maximum target journaling template is first object log template.So by 15 target journaling events and first object log template
Matching degree in minimum value as matching degree threshold value.Matching degree threshold value can be understood as in multiple target journaling events with first
Minimum value in the matching degree of target journaling template.
For example, contents extraction is carried out to the first log event in log to be extracted, the first log event is for example are as follows:

Matching degree, such as the format for the field for including in template X and template Y can successively be compared with the first log event, really
The matching degree of solid plate X is maximum, then carrying out contents extraction to the first log event according to template X, obtains the following contents:
