It is that stack top element is deleted so that it is adjacent element becomes new stack top element.
Daily record: the result in each stage that logging program performs.
Variable: variable refers to the amount that can change at any time in the running of program, corresponding with constant.
In an embodiment of the invention, it is provided that the running log to program as shown in Figure 1 carries out roller process
Scheme, sees Fig. 1, and each form represents the program daily record a periodic duty, in log database, only records nearest one
The section time such as N, (value of N is according to practical situation such as available memory space, the length etc. of the time needing monitoring) was in the individual cycle
The daily record that program is run: along with the passage of program runtime, at daily record (the solid line form mark that log database write is up-to-date
Know), and delete outmoded daily record (dotted line form mark), so that the data volume of the daily record of storage will not in log database
Ever-increasing situation occurs in time.
If the log processing scheme shown in Fig. 1 of employing, the most at least there is problems in that
1) after the daily record in log database is deleted, then cannot be to program at the operation produced problem of corresponding period
Investigate.
2) for the problem that the frequency of occurrences is relatively low, it is based only on the daily record in nearest N number of cycle and cannot be carried out investigating comprehensively, lead
Problem present in program cannot be investigated by cause in time.
Need from the daily record of the longer time span operation monitoring to program or the investigation of problem in the case of a lot,
In log database, the time span of the daily record of storage is limited, which increases the difficulty to program operation problem investigation, causes
The problem that in program operation process, some occurrence frequencies are low cannot be investigated discovery in time, if produced in the running of program
Raw daily record carries out full dose storage, then can cause taking substantial amounts of storage resource, be difficult to carry out equally.
3) program large-scale, complicated for some, the most only stores the daily record in N number of cycle in log database,
Also can take substantial amounts of memory space in log database, the data of the daily record of magnanimity cause utilizing daily record to run program
Problem carries out the efficiency investigated.
For the problems referred to above, the embodiment of the present invention provides log processing method, device and storage medium, by transporting program
During row, the daily record of output carries out classification other places reason, when the running status of program meets pre-conditioned, according to default
The daily record data of condition corresponding level forms journal file, by the rank of the pre-conditioned correspondence program to being in particular state
The rank of daily record data required when carrying out mistake investigation dynamically controls, and so there is no need to utilize all rank always
Daily record data forms journal file, even if the daily record data of program longtime running is formed journal file, it is also possible to reach joint
Save the effect of storage resource, simultaneously, it is also possible to guarantee that the journal file formed includes enough mistakes that carries out program and arranges
The daily record data looked into.
The embodiment of the present invention can provide log processing method and the log processing device of application log processing method, day
Will processing means can use the calculating resource in server or server cluster to realize, and Fig. 2 shows log processing device 10

The hardware configuration that it is pointed out that the log processing device 10 shown in Fig. 2 is the most all required, can basis
Practical situation omits the hardware configuration of implementation section, or, the hardware configuration of extension.It addition, the hardware knot shown in Fig. 2
Structure is at Same Physical position concentrated setting, or distribution is arranged on different physical locations, and set-up mode selects the most flexibly
Select.
One optional application scenarios schematic diagram of log processing device as it is shown on figure 3, in figure 3, log processing device
Being embodied as the server 10 for implementing log processing method, server 10 is by putting down program and the cloud of the 30 of cloud platform
The daily record that the program of platform 40 exports during running carries out classification other places reason, and the running status in program meets pre-conditioned
Time, form journal file according to the daily record data with pre-conditioned corresponding level and be stored in log database 20.At needs
Time based on the journal file in log database 20, program is investigated in the mistake that a certain period occurs, below in conjunction with specifically
Schematic flow sheet illustrate.
See an optional schematic flow sheet of the log processing method shown in Fig. 4, comprise the following steps:
Step 101, the daily record data that the program of acquisition exports in running.
As a example by Fig. 3, server 10 calls in daily record device (Logger) example record cloud platform 30 and cloud platform 40
The daily record data of program output, daily record device is the core component of log processing.There are 5 kinds of normal level (Level), including:
1) debugging level (static Level DEBUG)
DEBUG Level points out fine granularity message event, and debugging routine is had effect.
2) levels of information (static Level INFO)
INFO level shows that message highlights the running of program on coarse grain level.
3) alarm level (static Level WARN)
WARN level shows there will be the situation of latent fault.
4) error level (static Level ERROR)
Although ERROR level points out the event of making a mistake, but still does not affect continuing to run with of program.
5) severity level (static Level FATAL)
FATAL level points out that each grave error event will cause exiting of program.
It addition, also two available special daily record ranks:
static Level ALL
ALL Level is the lowest class, is used for opening all daily records.
static Level OFF
OFF Level is highest ranking, is used for closing all daily records.
The behavior of daily record device (Logger) is graduate.By the opening of the daily record data of appropriate level in control program
Close, the rank of the daily record data of program output can be controlled, in the embodiment of the present invention, control program and export the daily record of all ranks
Data, and it is selectively forming the journal file of log data.
Step 102, identifies the different stage belonging to institute's output journal data.
As a example by Fig. 3, the rank keyword that server carries based on the program output journal data in cloud platform 30, identify
Going out the daily record data of above-mentioned rank, similarly, the daily record data that server 10 exports based on the program in cloud platform 40 carries
Keyword recognition goes out the rank of corresponding daily record data.
Step 103, the state that detection program is run, determine that the state that program is run is met pre-conditioned.
Exemplarily, pre-conditioned exit for program exception, normal program operation terminates.
In one embodiment, pre-conditioned exiting for program exception, correspondingly, the state run when the program that detects is
When extremely exiting, then decision procedure now meet abnormal exit pre-conditioned.
In another embodiment, pre-conditioned terminate for normal program operation, correspondingly, when in the running of program
When not exporting the daily record data of FATAL rank, then can be determined that program meets the pre-conditioned of journey end of run.
Step 104, it is pre-conditioned that state based on program operation is met, first level based on pre-conditioned correspondence
Daily record data, at least one the daily record data of second level, form corresponding program pre-conditioned to meeting from bringing into operation
The journal file of period.
Step 105, the example in conjunction with the different corresponding journal files of pre-conditioned formation illustrates.
Example 1) pre-conditioned exit for program exception
As a example by Fig. 3, when abnormal situation about exiting occurs in the program in cloud platform 30, based on the debugging level (first order
Daily record data not) and the daily record data of severity level (second level), form corresponding program pre-to meeting from bringing into operation
If the journal file of the period of condition, here, severity level is any one rank removing debugging level in aforesaid rank, as
Error level, levels of information, alarm level etc..
In one embodiment, when program brings into operation, once get the daily record number of the severity level of program output
According to, then the daily record data of severity level is write journal file.Further, exit (also with regard to the running status of program when program exception
Satisfied exception exit pre-conditioned time), the daily record data of debugging level is also write journal file, thus based on debugging level
Daily record data and the daily record data of severity level, be collectively forming corresponding program from bringing into operation to meeting the pre-conditioned phase
Between journal file.
Exemplarily, in order to be lifted at when program exception exits, the daily record data of debugging level is write corresponding journal file
Efficiency, before program exits the most extremely or program off-duty terminates, by program export debugging level daily record data with
The mode of stack stores, and the daily record data stored the most afterwards is first read (last in, first out), writes importance level in journal file simultaneously
Other daily record data, when program exception exits, then reads the debugging level of stacked storage with the mode that last in, first out from stack
Daily record data, in conjunction with the daily record data of the debugging level having been written into daily record, form corresponding program from bringing into operation to meeting
The journal file of pre-conditioned period.
Mode based on stack can be lifted at need to journal file write debugging level daily record data efficiency, meanwhile,
Owing to the daily record data of severity level is synchronously written journal file, this guarantees the efficiency that journal file generates, especially
It is when the data volume of daily record data for output is the biggest, it is possible to significantly reduce the delay generating journal file.
The data volume of the daily record data produced in view of program is very big, read from stack debugging level daily record data it
After, the daily record data of the first level of stacked storage can be emptied, thus save storage resource.
Example 2) pre-conditioned terminate for normal program operation
As a example by Fig. 3, when abnormal situation about exiting occurs in the program in cloud platform 40, based on the severity level (second level
Daily record data not), the corresponding program of formation is from bringing into operation to the journal file meeting pre-conditioned period, here, important
Rank is except any one rank of debugging level in aforesaid rank, such as error level, levels of information, alarm level etc..
In one embodiment, when program brings into operation, once get the daily record number of the severity level of program output
According to, then the daily record data of severity level is write journal file, until program end of run, when program does not occur abnormal exiting
, there are not the abnormal feelings exited due to program in (when also the running status with regard to program meets properly functioning end pre-conditioned)
Condition, the daily record data being therefore not needed upon debugging level forms journal file, can be based only upon the daily record data of severity level
The corresponding program of formation is from bringing into operation to the journal file meeting pre-conditioned period, due to not by the daily record of debugging level
Data write journal file, therefore significantly reduces the data volume of journal file.
Exemplarily, before program exits the most extremely or program off-duty terminates, the debugging level that program is exported
Daily record data stores in the way of stack, and the daily record data stored the most afterwards is first read (last in, first out), simultaneously in journal file
The daily record data of write severity level, meanwhile, the daily record hands of severity level program exported is synchronously written journal file, so
At the end of normal program operation, owing to need not to utilize the daily record data of debugging level to form journal file, then can empty into
The daily record data of the first level of stack storage, thus save storage resource, and utilize the severity level having been written into journal file
Daily record data, form corresponding program from bringing into operation to the journal file meeting pre-conditioned period, say, that in journey
At the end of sort run journey, corresponding journal file has synchronized to generate, it is not necessary to carries out extra process again, improves daily record
The formation efficiency of file, for producing the program of a large amount of daily record datas, it is possible to be obviously improved treatment effeciency.
Step 105, the mistake produced program based on the journal file during at least one detects.
Exemplarily, the daily record data utilizing program to exit period at operation exception carries out mistake investigation, based on aforementioned step
Suddenly obtain having program stored therein in corresponding journal file the daily record data of debugging level of run duration, therefore can go out program
The reason of existing mistake is accurately investigated.
Exemplarily, program daily record data during properly functioning end is utilized to carry out mistake investigation, based on aforementioned step
Suddenly obtain having program stored therein in corresponding journal file the daily record data of severity level of run duration, therefore can go out program
Existing such as alarm level, the investigation of error level.
Illustrate in conjunction with an example forming journal file, see that forms journal file shown in Fig. 5
Optional schematic flow sheet, obtains the daily record data of program output after operation program, enters the rank of the daily record data of output
Row judges, if the daily record data of debugging level (such as variable, function name, function result etc.) is then by the daily record data of debugging level
Stacked storage, if the daily record data of severity level is then carried out record by the daily record data of severity level, namely writes daily record
File.
Meanwhile, whether the operation of detection program there is exception, if occurring abnormal, then needs the debugging level of stacked storage
Daily record data write journal file, the program that formed is at the journal file of this run duration.
If the operation being not detected by program occurs abnormal, then continue the daily record data of acquisition program output, it may be judged whether adjust
Try the daily record data of rank and process accordingly, until meeting one below:
1) detect that normal program operation terminates, utilize the daily record data shape of the severity level that recorded journal file
The journal file that one-tenth program is this time run.
2) detect that program exception exits, write journal file that the daily record data of the debugging level of stacked storage is popped,
Daily record data together with the severity level having been written in journal file forms the journal file that program is this time run.
Inventor finds in the practice of the invention, the actual application Program general relatively program of abnormal situation about exiting
The number of times of properly functioning end to lack, and therefore, only utilizes the day of debugging level and severity level at the end of program operation exception
Will data form journal file will save significantly on storage resource, even if thus can also in the case of storage resource is extremely limited
The journal file of storage program longtime running.And then, it is possible to (such as, reach the standard grade in cloud platform from program based on program longtime running
Since period, or the period of the whole test of program) journal file, relatively low to occurrence frequency in program operation process
Mistake investigate, investigate it is of course also possible to the program relatively early time is run the historical problem occurred.
The functional structure of aforementioned log processing device is illustrated, sees of the log processing device shown in Fig. 6
Optional logical functional structure schematic diagram, it should be pointed out that the logical functional structure of the log processing device shown in Fig. 6 is only
Being only exemplary, based on the logical functional structure shown in Fig. 6, those skilled in the art can carry out part to unit therein
Merging or carry out further splitting and reorganizing.
It addition, each unit in the logical functional structure shown in Fig. 6 can be realized by the hardware configuration shown in Fig. 1.
In figure 6, log processing device 50 includes: acquiring unit 51, recognition unit the 52, first detector unit 53, daily record
Unit 54 and the second detector unit 55, illustrate each unit below.
Acquiring unit 51, for obtaining the daily record data that program exports in running, such as, calls daily record device example
The daily record data of logging program output.
As a example by Fig. 3, server 10 calls in daily record device (Logger) example record cloud platform 30 and cloud platform 40
The daily record data of program output, daily record device is the core component of log processing.There are 5 kinds of normal level (Level), including:
1) debugging level (static Level DEBUG)
2) levels of information (static Level INFO)
INFO level shows that message highlights the running of program on coarse grain level.
3) alarm level (static Level WARN)
4) error level (static Level ERROR)
5) severity level (static Level FATAL)
By the switch of the daily record data of appropriate level in control program, the level of the daily record data of program output can be controlled
Not, in the embodiment of the present invention, control program and export the daily record data of all ranks, and be selectively forming log data
Journal file.

As a example by Fig. 3, the rank keyword that recognition unit 52 carries based on the program output journal data in cloud platform 10,
Identify the daily record data of above-mentioned rank, similarly, the daily record data that recognition unit 52 exports based on the program in cloud platform 30
The keyword recognition carried goes out the rank of corresponding daily record data.
First detector unit 53, for detecting the state that program is run, determines that the state that program is run is met default
Condition.
Exemplarily, pre-conditioned exit for program exception, normal program operation terminates.
In one embodiment, pre-conditioned exit for program exception, correspondingly, when the first detector unit 53 detects journey
When the state of sort run is for abnormal exiting, then decision procedure now meet abnormal exit pre-conditioned.
In another embodiment, pre-conditioned terminate for normal program operation, correspondingly, when the first detector unit 53 is examined
When measuring the daily record data not exporting FATAL rank in the running of program, then the program that can be determined that meets journey and runs knot
That restraints is pre-conditioned.

Or before program off-duty terminates, the daily record data of the debugging level that program exports is stored in the way of stack by log unit 54,
The daily record data the most first stored first is read (last in, first out), writes the daily record data of severity level in journal file simultaneously,
Meanwhile, the daily record hands of severity level program exported is synchronously written journal file, so at the end of normal program operation, by
Form journal file in the daily record data that need not utilize debugging level, then can empty the daily record number of the first level of stacked storage
According to, thus save storage resource, and utilize the daily record data of the severity level having been written into journal file, formed corresponding program from
Bring into operation to the journal file meeting pre-conditioned period, say, that at the end of program runs journey, corresponding day
Will file has synchronized to generate, it is not necessary to carries out extra process again, improves the formation efficiency of journal file, big for producing
For the program of amount daily record data, it is possible to be obviously improved treatment effeciency.
Second detector unit 55, examines for the mistake produced program based on the journal file during at least one
Survey.
Exemplarily, the daily record data utilizing program to exit period at operation exception carries out mistake investigation, based on aforementioned step
Suddenly obtain having program stored therein in corresponding journal file the daily record data of debugging level of run duration, therefore can go out program
The reason of existing mistake is accurately investigated.
Exemplarily, program daily record data during properly functioning end is utilized to carry out mistake investigation, based on aforementioned step
