The log preservation method that Fig. 1 provides for the embodiment of the present application, specifically comprises the following steps:
S101: the daily record configuration file reading application.
In the embodiment of the present application, suppose to apply current residing environment be stand-alone environment (namely, current environment), if will by place's application migration under the present circumstances to distributed environment (namely, targeted environment) under, need the daily record of this application from current environment migration (preservation) to targeted environment.
When daily record due to described application moves to targeted environment from current environment, the form of daily record is needed to change, to ensure that daily record effectively (namely normally uses) after being saved in targeted environment, and the definition of daily record configuration file has journal format, therefore, first the application needs the daily record configuration file reading the application before moving to targeted environment, to obtain journal format.
General, because the daily record of each application is preserved by the logging tools of this application self, concrete, logging tools can read daily record configuration file, and the daily record of application is preserved according to journal formats such as the daily record rank comprised in daily record configuration file, journal layout modes, therefore, when the embodiment of the present application server reads the daily record configuration file of application, specifically daily record configuration file can be read from the logging tools of this application.
General, at least include the journal formats such as daily record rank corresponding to current environment, journal layout mode in daily record configuration file, then the application can obtain the daily record configuration file comprising described journal format.
To take below journal format as daily record rank be example, illustrate and read daily record configuration file, to obtain the process of journal format.
Under normal circumstances, the daily record configuration file of certain logging tools can have various configurations mode, then in the embodiment of the present application, daily record configuration file can by the wherein a kind of realization in following several mode.
Mode one: all daily record ranks comprising this logging tools in daily record configuration file, as, the logging tools of current application is log4j, then can include all daily record rank FATAL, ERROR, WARN, INFO, DEBUG, TRACE of this log4j in this daily record configuration file, wherein, the rank height order of each daily record rank successively decreases successively according to arrangement sequencing.Then this daily record configuration file represents: the daily record exporting the daily record rank corresponded in daily record configuration file.
Mode two: the partial log rank comprising this logging tools in daily record configuration file, e.g., comprises front four (i.e. FATAL, ERROR, WARN, INFO) daily record ranks of log4j.Then this daily record configuration file represents: the daily record exporting the daily record rank corresponded in daily record configuration file.It should be noted that, (namely log4j has six kinds of daily record ranks, described in mode one six kind of daily record rank), and in mode two, contains only four kinds of daily record ranks in daily record configuration file, just represent that the daily record of these four kinds of daily record ranks that this application exports needs to preserve, the daily record of other two kinds of daily record ranks does not need to preserve.
Mode three: the some daily record ranks comprising this logging tools in daily record configuration file, e.g., comprises the 4th the daily record rank (INFO) of log4j.Then this daily record configuration file represents: export the daily record that (preservation) rank is not less than the daily record rank in this daily record configuration file.Also namely, only needing to preserve daily record rank is the daily record of FATAL, ERROR, WARN, INFO, and does not need the daily record of preserving other two kinds of daily record ranks.
It should be noted that, the logging tools described in the embodiment of the present application can be logging tools of increasing income, and also can be non-logging tools of increasing income, not do concrete restriction here.
It should be noted that in addition, in the embodiment of the present application, the daily record configuration file of application can be read by the logging tools in targeted environment, and perform following step S102 ~ S104.Concrete, before this is applied in and moves in targeted environment, himself may carry logging tools, but the logging tools himself carried be current environment (as, stand-alone environment), be not targeted environment (e.g., distributed environment), therefore, the daily record configuration file in the self-contained logging tools of this application can be read by the logging tools of targeted environment.Wherein, the logging tools of targeted environment can be arranged on the every station server in targeted environment.In addition, in order to avoid the logging tools of targeted environment clashes with the self-contained logging tools of application, when application moves to targeted environment from current environment, logging tools self-contained for this application can first be forbidden by the logging tools of targeted environment.
S102: determine the first journal format according to daily record configuration file.
Concrete, after reading out daily record configuration file by step S101, just can obtain the journal format in daily record configuration file, and determine the first journal format accordingly, this first journal format for described in be applied in the journal format before moving to targeted environment.
Such as, suppose that application needs to move to PaaS environment (targeted environment) from stand-alone environment (current environment), and the logging tools of application is log4j, this log4j is the logging tools of increasing income; Wherein, if daily record configuration file one is configured in the manner described above, then, server can read the daily record configuration file of logging tools log4j, daily record rank (journal format) in the daily record configuration file obtained comprises all daily record ranks of the logging tools of this daily record configuration file configuration, as, FATAL, ERROR, WARN, INFO, DEBUG, TRACE.Then can using each daily record rank of this acquisition as the first daily record rank.
Again such as, if daily record configuration file two is configured in the manner described above, then, server reads daily record configuration file, daily record rank (journal format) in the daily record configuration file obtained comprises partial log rank FATAL, ERROR, WARN, INFO of this logging tools, then also using each daily record rank of this acquisition as the first daily record rank.
Again such as, if daily record configuration file three is configured in the manner described above, then, server reads daily record configuration file, daily record rank (journal format) in the daily record configuration file obtained only comprises a daily record Grade I NFO in this daily record configuration file, all daily record ranks that then can be corresponding according to the logging tools of this current environment preserved in advance, search be not less than INFO other daily records rank FATAL, ERROR, WARN, FATAL, ERROR, WARN of to finding again, and INFO self is as the first daily record rank.It should be noted that, all daily record ranks corresponding for the logging tools of current environment can be kept in the logging tools of targeted environment in advance.
In upper example, the daily record rank determined according to read daily record configuration file, then can using the daily record rank in targeted environment as the second daily record rank as the first daily record rank.
S103: according to the first journal format determination transformation rule.
The embodiment of the present application, according to the first journal format determination transformation rule, specifically refers to according to the first journal format, determines the transformation rule of the journal format the first journal format being converted to targeted environment, using this corresponding relation as described transformation rule.The journal format of this targeted environment is as the second journal format, that is: when journal format is daily record rank, according to the first journal format determination transformation rule, be specially: according to the first daily record rank, determine the corresponding relation of the first daily record rank and the second daily record rank set up in advance, this corresponding relation is exactly the transformation rule that described needs are determined.
The journal format of different logging tools definition is generally different, and such as, the daily record rank (the first daily record rank) that the logging tools 1 under stand-alone environment defines comprises six kinds: FATAL, ERROR, WARN, INFO, DEBUG, TRACE; The daily record rank (the first daily record rank) that logging tools 2 under stand-alone environment defines comprises five kinds: FATAL, ERROR, WARN, INFO, DEBUG.But the daily record rank in PaaS environment (targeted environment) is: ERROR, WARN, INFO, DEBUG.Therefore, in the embodiment of the present application, can for each logging tools, preset each first daily record rank of this logging tools and the corresponding relation of each second daily record rank, this corresponding relation is exactly the transformation rule the first daily record rank being converted to the second daily record rank.
Visible, different logging tools, corresponding transformation rule is different.
After determined the first journal format in configuration file by step S102, need to determine the transformation rule corresponding with this first journal format from multiple default transformation rule.
Concrete, first can determine the daily record configuration file storing this first journal format, then determine the logging tools that this daily record configuration file is corresponding, then by transformation rule corresponding for the logging tools determined, be defined as the transformation rule that this first journal format is corresponding.
Along using example, the transformation rule of logging tools 1 and logging tools 2 difference correspondence as shown in Table 1 and Table 2.
| First daily record rank | Second daily record rank |
| FATAL | ERROR |
| ERROR | ERROR |
| WARN | WARN |
| INFO | INFO |
| DEBUG | DEBUG |
| TRACE | DEBUG |
Table 1
| First daily record rank | Second daily record rank |
| FATAL | ERROR |
| ERROR | ERROR |
| WARN | WARN |
| INFO | INFO |
| DEBUG | DEBUG |
Table 2
In Table 1, each first daily record rank is followed successively by from high to low: FATAL, ERROR, WARN, INFO, DEBUG, TRACE; In table 2, each first daily record rank is followed successively by from high to low: FATAL, ERROR, WARN, INFO, DEBUG.
Illustrate for table 1, when the daily record that the first daily record rank is FATAL moves in targeted environment, this daily record needs to be converted to the second daily record rank ERROR.In like manner, the first daily record rank is the daily record of TRACE when moving in targeted environment, and this daily record needs to be converted to the second daily record rank DEBUG.The daily record of all the other the first daily record ranks, when moving in targeted environment, is still simple.
Along using example, suppose that the first daily record rank reads from the configuration file of logging tools log4j, and above-mentioned logging tools 1 is logging tools log4j, then determine that transformation rule corresponding to the first daily record rank is the transformation rule that log4j is corresponding, this transformation rule is as shown in table 1.The transformation rule that three kinds of modes use is table 1.
S104: according to the transformation rule determined, carries out format conversion by the daily record that application exports, and is saved to designated store address.
In the embodiment of the present application, described designated store address can be previously defined in the logging tools of targeted environment, server is when preserving daily record, can from the logging tools of targeted environment, obtain this designated store address and preserve daily record, this designated store address can be the daily record center in targeted environment.
In the embodiment of the present application, according to the transformation rule determined, format conversion is carried out in the daily record that application exports, and be saved to designated store address, be specially, according to the corresponding relation (i.e. transformation rule) of the first daily record rank set up in advance and the second daily record rank, the first daily record rank of the daily record this application exported converts the second daily record rank to, and according to the memory address read from logging tools, daily record is saved in described memory address.
Along using example, if daily record configuration file one is configured in the manner described above, the the first daily record rank then determined by step S102 is all daily record rank (FATAL of logging tools log4j, ERROR, WARN, INFO, DEBUG, TRACE), then pass through the corresponding relation of the first daily record rank shown in table 1 and the second daily record rank, the each first daily record rank determined is converted to the second daily record rank, concrete, FATAL is converted to ERROR, and TRACE is converted to DEBUG, other the first daily record rank (ERROR, WARN, INFO, DEBUG) former form can be kept.Daily record after this format conversion is kept at the daily record center of PaaS environment.
In method shown in above-mentioned Fig. 1, server only needs to read daily record rank in the daily record configuration file before application migration as the first daily record rank, and according to default transformation rule, first daily record rank is converted to the second daily record rank being applicable to targeted environment, and the daily record after this format conversion is kept at designated store address (as, the daily record center of PaaS environment), like this, after the daily record of applying moves to targeted environment, because its journal format has been converted to the journal format being applicable to targeted environment, effectively can ensure to aim at targeted environment this day effective, in addition, all daily records of applying all unification are kept at described designated store address, be convenient to follow-up checking.Visible, the method does not need to revise each api interface in logging tools and relevant configuration, just the daily record of application can be moved to targeted environment, effectively can improve the transport efficiency of application.
In the embodiment of the present application, further, due to by after application migration to targeted environment, the form of its daily record exported there occurs change, therefore, check the daily record stored in targeted environment for the ease of user, occur when avoiding checking daily record feeling uncertain, above-mentioned daily record is saved in described memory address before, described method also comprises: the mark adding the first daily record rank of this daily record before conversion in the daily record after conversion.
Such as, the daily record after format conversion is kept at daily record center by the application, and wherein, the daily record rank before this format conversion is TRACE, and the daily record rank after format conversion is DEBUG.When then preserving (output) this daily record, in the daily record after format conversion, add inlet identity TRACE.Then when showing this daily record, the mark TRACE added in show log, and do not show the daily record rank DEBUG of its reality.
Such as, " JAVA_Trace:rget () flags:0yq34javaruntime " is the log content shown under PaaS environment.The daily record of this to be a daily record rank be under the present circumstances TRACE rank, when moving to targeted environment, its daily record rank has been converted to DEBUG rank, but, because the logging tools of targeted environment is before being saved in daily record center, mark TRACE is added in this daily record, therefore, contain mark TRACE in shown daily record, and do not show the daily record rank DEBUG after its conversion, thus be convenient to user and check, occur feeling uncertain when avoiding user to check daily record.
In the embodiment of the present application, by in application migration to targeted environment time, except the daily record of this application is moved to targeted environment, also comprise and the language output statement of this application is also moved to targeted environment, be convenient to for this application service (using when e.g., ensureing that this application normally starts or debugs this application).

S202: the output classification determining described language output statement.
It should be noted that, in order to the language output statement of current environment normally can be saved in targeted environment designated store address (as, daily record center), language output statement is needed to preserve as special daily record, after such guarantee moves to targeted environment, the output content of language output statement is saved in designated store address, so need the classification determining language output statement; Wherein, the journal format of described special daily record (language output statement) is daily record rank.
Because language output statement comprises output classification, therefore, the output classification in this language output statement can directly be read.
Along using example, export classification out owing to comprising in the language output statement System.out.println (" test ") that reads out, therefore, can determine that the output classification of this language output statement is for correct (out).
S203: according to the corresponding relation of each output classification set up in advance and the second daily record rank, determine the second daily record rank that the output classification of described language output statement is corresponding.
Concrete, the output classification of the language output statement set up in advance and the corresponding relation of the second daily record rank as shown in table 3.
| The output classification of language output statement | Second daily record rank |
| err | ERROR |
| out | INFO |
Table 3
Continue along using example, when the output classification determining language output statement is correct out, then as shown in Table 3, the second daily record rank of the corresponding targeted environment of this output classification is INFO.
S204: using the daily record of the output content of described language output statement as the second daily record rank determined, be saved in described designated store address.
Along using example, the output classification of the current environment language output statement read is out, second daily record rank of corresponding targeted environment is defined as INFO, then using the daily record of the output content of statement as the INFO daily record rank determined, by output redirection, output content is saved in designated store address (daily record center).
In method shown in above-mentioned Fig. 2, when applying needs and moving to targeted environment from current environment, server only needs to read language output statement, determine the output classification of language output statement, according to the corresponding relation of each output classification set up in advance and the second daily record rank, determine the second daily record rank that the output classification of described language output statement is corresponding, using the daily record of the output content of described language output statement as the second daily record rank determined, be saved in described designated store address.By said method, just language output statement can be saved in daily record center, highly versatile, transplanting efficiency is high.
