Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with attached drawing to the application embodiment party
Formula is described in further detail.
Firstly, being explained for noun involved in the embodiment of the present application.
Accesstime (access moment): i.e. atime, at the time of for indicating that the data in file are finally accessed.This
Apply in embodiment, which is used to determine the establishment moment of journal file, wherein the atime includes second grade atime, milli
Second grade atime and nanosecond atime, this second grade atime are used to determine the second grade establishment moment of journal file, Millisecond
Atime is used to determine the Millisecond establishment moment of journal file, and nanosecond atime is used to determine the nanosecond wound of journal file
Build the moment.Wherein, second grade establishment moment is the establishment moment with the second for minimum measurement unit, and Millisecond establishment moment is with millisecond
For the establishment moment of minimum measurement unit, nanosecond establishment moment is the establishment moment with nanosecond for minimum measurement unit.
Modifiedtime (modification moment): i.e. mtime is changed when file is written with the change of file content.This
Apply in embodiment, what which was determined for journal file is ultimately written the moment, wherein the mtime includes second grade
Mtime, Millisecond mtime and nanosecond mtime, this second grade mtime are used to determine grade write-in moment second of journal file, milli
Second grade mtime is used to determine the Millisecond write-in moment of journal file, and nanosecond mtime is used to determine the nanosecond of journal file
The moment is written.Wherein, the second grade write-in moment is the write-in moment with the second for minimum measurement unit, and the Millisecond write-in moment is with milli
Second is the write-in moment of minimum measurement unit, and the nanosecond write-in moment is the write-in moment with nanosecond for minimum measurement unit.
Changetime (variation moment): i.e. ctime, write-in file, change file owners, change file permission or
Person is changed when changing the linking relationship of file.In the embodiment of the present application, which can be used for determining journal file
It is ultimately written the moment, wherein the ctime includes second grade ctime, Millisecond ctime and nanosecond ctime, this second grade
Ctime is used to determine grade write-in moment second of journal file, and Millisecond ctime is used to determine the Millisecond write-in of journal file
Moment, nanosecond ctime are used to determine the nanosecond write-in moment of journal file.Wherein, it is most that the second grade write-in moment, which is with the second,
The write-in moment of small measurement unit, Millisecond write-in moment are the write-in moment with millisecond for minimum measurement unit, and nanosecond is write
The write-in moment for the minimum measurement unit that enters that be with nanosecond constantly be.
Establishment moment: at the time of the establishment moment refers to that journal file is created.After being created, the journal file is initial
It for an empty journal file, i.e., does not include log content in the journal file.
It is ultimately written the moment: being ultimately written and refer to constantly log content is persistently written after journal file is created, work as log
At the time of content terminates write-in in the journal file.Optionally, each journal file includes the write-in upper limit, is limited the use of in the write-in
In the size for controlling each journal file, such as: the write-in upper limit of each journal file is 2GB, then when log content is in log text
In part write-in is when reaching 2GB, and at the time of end is written in journal file, the as journal file is ultimately written the moment.
Secondly, to the invention relates to journal file rolling process be illustrated, with writing for each journal file
Enter for the upper limit is 2GB and is illustrated.
Firstly, creation logfile, and log content is written in logfile, it, will when writing full 2GB in the logfile
The logfile is renamed as logfile1 and is saved；Logfile is created again, and is write in the newly created logfile
Enter log content, when writing full 2GB in logfile, former logfile1 is renamed as logfile2, full logfile will be write
It is renamed as logfile1 and is saved, and creates logfile again, and so on.
In a possible situation, it is different that rolling can be generated when two journal files have log content to be written into simultaneously
Often, referring to FIG. 1, at the first moment to being written into log content A between the second moment, in logfile1, and it is newly created
Log content B is written into logfile, after the second moment, new creation is written in log content A and log content B simultaneously
Logfile in.Then between the first moment and the second moment, logfile and logfile1 have log content to be write simultaneously
Enter, so can generate, rolling is abnormal, and the rolling abnormal last modification moment for only passing through journal file can not be detected.
Wherein, synchronization cannot have two journal files has log content to be written into and (generate and roll exception) simultaneously
The reason of mainly have following two points:
First, journal file, which rolls system requirements, cannot have two journal files while have log content to be written into；
Second, when being written into log content simultaneously there are two journal file, to the other systems for relying on the journal file
Running can have an impact.Schematically, the monitoring system quantity that statistical system is requested from journal file, and monitoring system exists
When statistics, the quantity that only statistical system is requested from the journal file for be currently written into log content, when simultaneously, there are two log texts
When log content is written in part, the system request being written in the journal file that first the creates system statistics that can not be monitored are arrived, and cause to supervise
The quantity inaccuracy for the system request that control system statistics are arrived namely the statistical result inaccuracy of the monitoring system.
It is worth noting that, i-th of journal file and i+1 journal file involved in the embodiment of the present application be according to
What the sequence that journal file is created successively determined, i.e. first journal file being created is the 1st journal file, the
Two journal files being created are the 2nd journal file, and n-th of journal file being created is n-th of journal file.
Wherein, the naming order of journal file can be in sequence with the creation sequence of journal file, can also be with the creation of journal file
Sequence is in inverted order.It is illustrated so that the creation of the naming order of journal file and journal file sequence is in inverted order as an example, it is assumed that altogether
There are 5 journal files, first journal file being created is named as logfile5, second journal file name being created
For logfile4, the journal file that third is created is named as logfile3, and the 4th journal file being created is named as
Logfile2, the 5th journal file being created are named as logfile1, and nearest one is created and is currently written into log
The journal file of appearance is logfile.After being created when nearest one and be currently written into the journal file of log content and write full, successively
Logfile5 is renamed as logfile6, logfile4 is renamed as logfile5, and logfile3 is renamed as logfile4,
Logfile2 is renamed as logfile3, and logfile1 is renamed as logfile2, and logfile is renamed as logfile1, and creates again
Build logfile.
Fig. 2 is the flow chart of the rolling abnormality judgment method for the journal file that one exemplary embodiment of the application provides,

Establishment moment can be obtained by directly reading the atime of the i+1 journal file of storage.
It optionally, does not include log content in the journal file, and the i+1 when which is created
A journal file includes the write-in upper limit, that is, the i+1 can be written in the log content for being no more than write-in upper limit size by server
A journal file.
Optionally, which can be the file for having created and having terminated write-in log content, i.e., this
Log content in i+1 journal file has reached the write-in upper limit, and the i-th+2 journal files have been created；The i+1
Journal file is also possible to a nearest journal file being created, i.e. the i+1 journal file is currently written into log
Hold, and the i-th+2 journal files are not created also.
Step 202, determine i-th of journal file is ultimately written the moment.
Optionally, this be ultimately written constantly for log content be ultimately written i-th of journal file at the time of, this is i-th
The establishment moment of journal file is before the establishment moment of above-mentioned i+1 journal file.
Optionally, the moment that is ultimately written of i-th of journal file can be by directly reading i-th day of storage
The ctime of will file is obtained, and can also be obtained by directly reading the mtime of i-th of journal file of storage.
Optionally, which creates before i+1 journal file, has created i-th of journal file
Afterwards, i-th of journal file is written into log content, when the log content that i-th of journal file is written meets predetermined condition
When, terminate that i-th of journal file is written log content into, then terminate to be written log content i-th of journal file when
It carves, as i-th of journal file is ultimately written the moment.Wherein, above-mentioned predetermined condition includes at least one in following condition
Kind:
First, the size that the log content of i-th of journal file is written reaches the write-in upper limit；
Second, the duration that i-th of journal file is written in log content reaches maximum time limit.
Step 203, when the establishment moment of i+1 journal file i-th journal file be ultimately written the moment before
When, determine that the rolling of journal file is abnormal.
The rolling refers to i-th of journal file and i+1 journal file extremely while having log content to be written into and producing
Raw exception.Optionally, the log content that i-th of journal file and i+1 journal file are written simultaneously can be difference
, it is also possible to identical.Such as, in synchronization, log content A is written i-th journal file, and log content B is written into the
I+1 journal file.
Optionally, the establishment moment to the i+1 journal file of acquisition and i-th journal file are ultimately written the moment
Be compared, when the establishment moment of i+1 journal file i-th journal file be ultimately written the moment before when, then say
It is bright after i+1 journal file is created, still have log content that i-th of journal file is written, namely illustrate i+1 day
Will file and i-th of journal file in establishment moment and are ultimately written in the period between the moment, while having log content quilt
Write-in.
In conclusion the rolling abnormality judgment method of journal file provided in this embodiment, by obtaining the day first created
The last modification moment of will file, and the establishment moment of journal file created afterwards, when the establishment moment is in the last modification
When before the moment, then it represents that after the journal file created afterwards is created, log content also in the journal file that first creates of write-in,
Namely indicate that two journal files exist while having the phenomenon that log content is written into, cause to roll exception, improve to rolling
Move abnormal detection accuracy.
In an alternative embodiment, above-mentioned i+1 journal file is a nearest journal file being created, needle
The i+1 journal file and i-th of journal file are carried out rolling abnormal judgement, i.e., during creating journal file,
To abnormal progress real-time judge is rolled, Fig. 3 is that the rolling for the journal file that another exemplary embodiment of the application provides is abnormal
Judgment method, as shown in figure 3, the judgment method includes:
