Embodiment
It is described in detail below in conjunction with accompanying drawing embodiment of this disclosure.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explained the disclosure, is not limited to the disclosure.
Fig. 1 is a kind of flow chart of index managing method for log query according to an exemplary embodiment,
As shown in figure 1, this method comprises the following steps：
Step 110, the query pattern being related to by analyzing in current queries, it is determined that target rope corresponding with query pattern
Draw.
The file with certain rule generated when daily record is system operation, usual computer, the network equipment, system and clothes
Business program etc., operationally can all produce historical events record, per a line daily record all recite the date, the time, user and
The description of the associative operations such as action.After computer system generates daily record, day that can be by way of inquiry to having generated
The content of will file (a plurality of daily record can be included in journal file) is transferred, so as to in computer system it is specific some
Some certain content in journal file is re-read, so as to obtain the operation shape of the computer system under the log recording
The relevant information of state.Illustratively, before inquiry is performed to log content, the daily record text of all distributed storages can be traveled through
Part, and according to the corresponding daily record mapping table of Model Establishment of daily record, the content of wherein daily record mapping table includes：Day aims at mapping table
In identity (such as ID), field information, the positional information where the daily record, and positional information includes the log path (example
The routing informations such as main frame, disk, file as where daily record), the length of the offset of the daily record and the daily record.By upper
The method for setting up mapping table stated, can reduce the information content of centralized management, so as to reduce empty to the storage needed for log management
Between.Every corresponding index of mapping is set up further according to the daily record mapping table afterwards, and index temperature is set up for each index
The ranking of the search temperature of current all indexes is have recorded in sequencing table, the index temperature sequencing table, in any one index
It is queried and is once required for the search temperature for updating this index afterwards, so that the following index temperature to after renewal carries out temperature
Again ranking, so that the ranking of the search temperature newest according to the index is managed to the index in the buffer in subsequent operation
Reason.The above method reduction centralized management information content, reduction log management needed for memory space while, by index
Dynamically managed, accelerate inquiry velocity, reduce the exchange expense between high speed/low speed caching.
Therefore in this step, query pattern can be understood as user-defined query statement, i.e. user based on being inquired about
One section of sentence for inquiring about the content related to these aiming fields that certain several aiming field is write.Indexed on target
It is determined that can include：Determine whether target index has been present according to the query pattern of daily record first, if directly right in the presence of if
Target index carries out the operation of next step 120, conversely, when target index is not present, then needing a first newly-built target
Index, and the index temperature of target index now, should be default initial temperature, for example, could be arranged to 0, enter again afterwards
Row step 120.
Step 120, index temperature target indexed increases a unit temperature, obtains the rope after the renewal of target index
Draw temperature.
After the index of the target corresponding to query pattern is determined in step 110, then need to search the target index
Rope temperature number of times is increased.For example, a unit temperature can be represented with 1.When performing inquiry, find there is the target
During index, then add 1 to the index temperature that the target is indexed, obtain the index temperature after the renewal of target index, then walked
Rapid 130 carry out the renewal of temperature ranking；Or, when it is newly-built index in step 110 that the target, which is indexed, the now target
The temperature of index should be 1.
Step 130, the current temperature ranking that target is indexed is obtained according to the index temperature after renewal.
Because the index temperature in the step 120 to corresponding target index in this inquiry operation is updated, because
The current temperature ranking of this corresponding target index is also required to update the current temperature ranking for obtaining target index again again.
According to the index temperature after renewal, it will index and carry out ranking according to the order of index temperature from high to low, obtain mesh
Mark the current temperature ranking of index.Wherein, when there is multiple index temperature identical indexes, by multiple index temperature identicals
Index carries out ranking according to the order of the renewal time of temperature from the front to the back is indexed.When there is ranking arranged side by side in multiple indexes, position
It is that ranking is carried out according to its renewal time for indexing temperature from the front to the back in all and column index orders of the juxtaposed position,
The ranking of the index updated more afterwards more before, that is, when there is multiple index temperature identicals indexes, the index of final updating
First sorted side by side is come, then ranking from the front to the back in chronological order successively.
Step 140, it is when determining that target index meets preparatory condition according to current temperature ranking, target index write-in is high
Speed caching.
Wherein, cache is the spatial cache for storing the index being commonly used, similar to internal memory or SSD (English
Text：Solid-State Disk, Chinese：Solid state hard disc), be used in usual cache storing the space of index have it is certain
Capacity limit.
In the present embodiment, target index write cache is included：It is existing and positioned at vulgar in target cache
When in caching, target index is cached into write cache from low speed, or in target cache in the absence of (now index temperature is arranged
The target index just created has been added in sequence table, but has been not present in caching), it is when creating for the first time, then to need synchronous at a high speed
The target cache is created in caching.But it is due to that each index needs to take certain memory space, thus it is slow at a high speed in write-in
, it is necessary to be judged first before in depositing, whether the target cache meets the preparatory condition of write-in, then the operation write,
Judge the explanation referring to the following examples the step of now whether meet the preparatory condition of write cache.So at a high speed
The index stored in caching will be index in have higher thermal degree ranking index, by each index search temperature dynamically
Index in cache is updated, so that the management of optimum indexing.
In summary, the index managing method for log query that the disclosure is provided, is related to by analyzing in current queries
And query pattern, it is determined that target corresponding with query pattern is indexed, the index temperature for then indexing target increases a list
Position temperature, obtains the index temperature after the renewal of target index；Working as target index is obtained further according to the index temperature after renewal
Preceding temperature ranking；When current temperature ranking determines that target index meets preparatory condition, target is indexed into write cache.Energy
It is enough to carry out ranking to judge whether to index target in write cache by the search temperature to index, so as to basis
The search temperature of index enters Mobile state renewal to the index in cache, so as to search for the higher index of temperature when can be longer
Between storage in the caches, so as to while ensureing that the higher index of search temperature can be by quick search, also ensure
The index will not frequently be exchanged between cache and low speed caching again, it is to avoid it is serious to be easily caused systematic function
The problem of decline.
Further, Fig. 2 is another index management side for log query according to an exemplary embodiment
The flow chart of method, as shown in Fig. 2 the query pattern being related to by analyzing in current queries described in step 110 in Fig. 1, really
Fixed target index corresponding with query pattern includes：
Step 111, the query pattern being related to by analyzing in current queries, obtains the target word to be inquired about of query pattern
Section.
Illustratively, the determination of query pattern is built upon on the basis of the rule of generation daily record, should be only right for inquiry
A certain partial content carries out a regular extraction, can be with filter condition or canonical.And query pattern institute
The statement of corresponding aiming field should be unique, therefore to being that can determine that the aiming field to be inquired about according to query pattern,
So as to carry out the operation of step 112, indexed with determining whether there is corresponding target.
Step 112, determine that target corresponding with query pattern is indexed according to aiming field.
Example, determine in step 111 after the aiming field to be inquired about determined further according to the aiming field be
It is no to there is the index comprising aiming field, wherein in the present embodiment, search whether to refer in the presence of the index comprising aiming field
Searched in above-mentioned index temperature sequencing table；Target index is determined afterwards, that is,：When (in index temperature sequencing table) has bag
During one or more indexes containing aiming field, one or more indexes are defined as target index；Or, when (index temperature
In sequencing table) when one or more indexes comprising aiming field are not present, by according to aiming field travel through journal file come
One or more indexes comprising aiming field are created to index as target, and after target index is created, by the target rope
Draw and be added in the index temperature sequencing table, the index created in addition includes the aiming field, the main frame road where journal file
Offset in footpath, journal file, the information such as the length of daily record.
Example, it is assumed that need to search the daily record that ip is 10.4.45.129 in journal file, then can be in index temperature
Inquiry is with the presence or absence of the index for including ip fields in sequencing table, and the wherein description of query pattern for example can be：^(<ip>\d
+\.\d+\.\d+)[\s\S].When there is the index comprising ip fields, the index is exactly the target index that we need, when not
, it is necessary to create the target index during in the presence of index comprising ip fields, establishment process can include：Travel through in specified range and own
Distributed information log file, according to above-mentioned query pattern ^ (<ip>D+ d+ d+) [s S] extract every daily record
It is worth and sets up index, index includes：Offset in host paths where ip value, journal file, journal file, daily record
The information such as length.
Then, the index managing method described in step 141 to 145 is performed, no matter whether target index is located at height afterwards
On speed caching, ip=10.4.45.129 daily record is all filtered on target index.
Optionally, Fig. 3 be according to an exemplary embodiment another be used for log query index managing method
Flow chart, as shown in figure 3, described in step 140 in Fig. 1 when determining that target index meets default according to current temperature ranking
During condition, target index write cache is included：
Step 141, determine whether target index is located in cache.
Judge whether target index is located in cache, when target index is had been positioned in cache, explanation
Do not need in write cache again；Otherwise with regard to the operation of progress step 142.
Step 142, when target index is not in cache, it is determined that whether current temperature ranking is more than or equal to
Default ranking.
When judging that target index is not in cache, further according to its current temperature ranking, step 143 is carried out
Or the operation of step 144.
Step 143, when current temperature ranking is more than or equal to default ranking, judge whether target index meets default bar
Part.
Example, when the current temperature ranking that the target is indexed is the 20th, and default ranking is 30, then explanation can be with
The step of whether meeting preparatory condition is determined further, judges the step of target index meets preparatory condition referring to following
Fig. 4 embodiment.
The judged result of this step there is also two kinds of situations, the first：When meet target index meet preparatory condition when, will
Target indexes write cache.Wherein, target index write cache is also included：In the first case：Work as target
When index is the index created first, target index is set up in cache；In second of situation：When target index is present in
When low speed is cached, read from low speed caching after target index, target is indexed into write cache.That is, the inquiry
Corresponding target is operated to index when being not present in caching, it is necessary to when newly-built, directly can set up target index in height
On speed caching；Another situation is exactly that target index had built up, but index temperature before ranks behind, therefore
It is stored in low speed caching, and now the target indexes the temperature ranking of temperature ranking after temperature ranking after correspondence updates
Meet preparatory condition again, therefore write cache again after being read from low speed caching.
Second, when discontented foot-eye index meets preparatory condition, the operation of step 145 is carried out, that is, by the mesh
Mark index is stayed in low speed caching.
Step 144, when current temperature ranking is less than default ranking, determine that target index is unsatisfactory for preparatory condition, refuse
Target is indexed into write cache.
Example, when default ranking is 30, and the current temperature ranking of target index is when being 35, i.e. current temperature row
Name is less than default ranking, it is determined that the target can not be indexed into write cache, then continues the operation of step 145.
Step 145, when determining that target index is unsatisfactory for preparatory condition according to current temperature ranking, target is indexed and retained
In low speed caching.
When target index is unsatisfactory for the preparatory condition of write cache, two kinds of situations can also be divided into, when target rope
Draw when being the index created first, then by target index creation in low speed caching, delay when target index is already present on low speed
In depositing, then target index also retains in the original location, i.e., in low speed caching, until meeting preparatory condition according to its temperature ranking
Afterwards, just can be with write cache.
Further, Fig. 4 be according to an exemplary embodiment another be used for log query index management side
The flow chart of method, when judging whether target index meets preparatory condition, the current temperature ranking except considering target index, also
It is contemplated that whether the buffer memory capacity for being used to store index in cache is enough, as shown in figure 4, described in the step 144 in Fig. 3
When current temperature ranking is more than or equal to default ranking, determine that target index meets preparatory condition, and target index is write
Entering cache includes：
Step 1441, when current temperature ranking is more than or equal to default ranking, determine that being used in cache stores
Whether the buffer memory capacity of index is enough.
Example, the buffer memory capacity can choose 30 percent of total capacity shared by all indexes and system distributed
Minimum value in the two of largest buffered capacity limit.Judging that being used in cache now is stored in the caching of index is
No stored full, whether its residual caching capacity also writes new index enough, then judges to carry out step 1442 or step
Rapid 1443 operation.
Step 1442, when it is determined that buffer memory capacity is enough, target is indexed into write cache.
Step 1443, when it is determined that buffer memory capacity is not enough, it is by temperature ranking in all indexes stored in cache
Last index is deleted from cache.
Judge the buffer memory capacity in the cache when not enough continuing to store, it is necessary to delete stored in step 1441
Index in cache, obtains enough buffer memory capacity to be stored in target index, it is the last that selection will index temperature
Index is deleted.Carry out the judgement of step 1444 again afterwards.
Step 1444, it is determined whether buffer memory capacity enough indexes target in write cache.
After the last index is deleted in step 1443, it is determined that now there is enough capacity to carry out mesh in cache
When marking the write-in of index, the deterministic process can be terminated, target is directly indexed into write cache.Otherwise need to be from step 1441
Restart, untill step 1444 determines to meet.It is, being that last index is slow from high speed by temperature ranking
Deposit after deletion, perform determine that being used in cache stores the whether enough steps of the buffer memory capacity indexed again, until
Determine when buffer memory capacity is enough target indexing write cache.Wherein, when target index is that temperature ranking is last position
Index when, refusal target is indexed into write cache.
Because the space shared by different index is inconsistent and buffer memory capacity of cache is limited, therefore in ablation process
Whether the middle buffer memory capacity that need to be determined in cache meets the requirement of the required amount of capacity of the target index that will be write,
When being unsatisfactory for, then the cleaning of buffer memory capacity is carried out first, the last index of temperature is deleted successively, until buffer memory capacity size
