Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
The embodiment of the present application discloses a kind of log rank amending method, in the feelings for not influencing kernel module business continuance
Log rank is modified under condition.
Referring to Fig. 1, a kind of flow chart of log rank amending method shown according to an exemplary embodiment, such as Fig. 1 institute
Show, comprising:
S101: the log grade variable of kernel state module definition is obtained；Wherein, the log grade variable is global becomes
Amount；
The executing subject of the present embodiment is the controller in kernel state, i.e. the present embodiment kernel in core state in the prior art
Increase controller on the basis of module.Firstly, the log grade variable of kernel state module definition, which is the overall situation
Variable can be realized shared between controller and kernel module.
S102: defining the addressable communication interface of consumer process, with will pass through the communication interface receive the user into
The target value that journey is sent；
In specific implementation, controller is based on character device, i.e. controller provides a communication interface and realizes and use
Exchanging visit between the state of family.Consumer process in User space can send log by controller of the communication interface into kernel state
The target value of grade variable.The communication interface can be specially ioctl interface, herein without specifically limiting.
For log4j, which includes ALL, TRACE, DEBUG, INFO, WARN, ERROR, FATAL and OFF
Any one of.Log4j defines the log of 8 ranks, and priority is from high to low successively are as follows: OFF, FATAL, ERROR,
WARN,INFO,DEBUG,TRACE,ALL.ALL the lowest class, it is used to open all log recordings.TRACE is very low day
Will rank, not will use generally.DEBUG point out fine granularity message event be to debugging utility it is very helpful, mainly
For printing some operation informations in development process.INFO message highlights the operation of application program on coarse grain level
Journey can be used for some important informations that output program is run in production environment, but cannot abuse, and avoid printing excessive day
Will.WARN shows the situation that will appear latent fault, some information are not error messages, but also to mention to some of programmer
Show.Although ERROR points out that error event occurs, but still does not influence continuing to run for system.Misprint and exception information, such as
Fruit is not desired to export too many log, this rank can be used.FATAL points out that each grave error event will will lead to application
Program exits.OFF is highest level, for closing all log recordings.
If being arranged log grade variable in some rank, the log higher than this level priorities can be beaten
It prints off and.For example, the log of tetra- ranks of OFF, FATAL, ERROR, WARN can be normal if setting priority is WARN
Output, and the log of INFO, DEBUG, TRACE, ALL rank can then be ignored.In general, four ranks are used only in Log4j,
Priority is ERROR, WARN, INFO, DEBUG respectively from high to low.
S103: the target value is set by the log grade variable, and current log grade variable is shared to institute
State kernel module.
In this step, the incoming target value of User space is set by log grade variable, and by modified journal stage
Other variable and kernel module, which are realized, to be shared, so far by controller dynamic modification kernel state module log rank, in modification log
Reconstruct kernel module is not needed when rank.
Log rank amending method provided by the embodiments of the present application increases real between controller, with kernel module in kernel state
Existing variable is exchanged visits, and log grade variable is the global variable of kernel state module definition, and controller can be by the log grade variable
It is revised as the incoming target value of User space, is realized in User space dynamic modification kernel state module log rank.In modification journal stage
Reconstruct kernel module is not needed when other, is improved system business continuity, is increased the convenience of system debug and maintenance.
A kind of Application Example of log rank amending method provided by the present application is described below, specifically includes following step
It is rapid:
Step 1: kernel module defines kernel state overall situation log grade variable, and is exported by EXPORT_SYMBOL, log
Output passes through the Variable Control rank (DEBUG, ERROR etc.).
Step 2: it realizes a kernel control module based on character device, defines the addressable ioctl interface of User space,
Kernel control module quotes the header file of log rank variable-definition in kernel module.Kernel control module with kernel module together
It is loaded onto system kernel.
Step 3: User space program is passed to log rating value to kernel control module, and kernel control module passes through kernel state
Variable is exchanged visits, and is realized and is modified the other dynamic of journal stage in kernel module.
A kind of log level modification system provided by the embodiments of the present application is introduced below, a kind of day described below
Will level modification system can be cross-referenced with a kind of above-described log rank amending method.
