Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The present invention can be used in numerous general or special purpose computingasystem environment or the configuration.For example: personal computer, server computer, handheld device or portable set, plate equipment, multicomputer system, the system based on microprocessor, network PC, small-size computer, mainframe computer, comprise distributed computing environment of above any system or equipment or the like.
The present invention can describe in the general context of the computer executable instructions of being carried out by computing machine, for example program module.Usually, program module comprises the routine carrying out particular task or realize particular abstract, program, object, assembly, data structure or the like.Also can in distributed computing environment, put into practice the present invention, in these distributed computing environment, by by communication network connected teleprocessing equipment execute the task.In distributed computing environment, program module can be arranged in the local and remote computer-readable storage medium that comprises memory device.
A good journal file, under the prerequisite that can guarantee the normal operation of system, the information that is write down does not lie in many, and is valuable.And the situation in the reality is, the journal file of system can write down various information as much as possible, comprising the lower information of some ranks, as other information of Verbose level, completely all can go on record.And under most of situation, this other information of level that is to say that to the not too big help of check system operation problem this information just belongs to unworthy information.And this valueless information has also taken storage space greatly usually; moreover; when the daily record amount is big; also will have influence on the efficient of user inquiring daily record; want to know such as the user why certain functional module makes mistakes; the log information major part that inquiry obtains is other information of Verbose level, just can reflect in the log information more than the Event rank often and in fact make mistakes.
Inventor just because of this patent has noticed this point, therefore, one of core idea of the embodiment of the invention has been proposed innovatively, promptly by setting in advance the required satisfied level conditions of log record, when writing log record, have only the log record that satisfies this level conditions just to be written into, this mode not only can reduce the storage space that daily record takies, can also in journal file, store valuable information as much as possible, thereby improve the efficient of user inquiring daily record.
With reference to figure 1, show the process flow diagram of a kind of log recording method embodiment 1 of the present invention, specifically can may further comprise the steps:
In specific implementation, described step 104 also can be to ignore described log record, can also be the relevant information of this log record of deletion, and the present invention is not limited this.
In a preferred embodiment of the present invention, described daily record rank and default level conditions can be configured in configuration file.For example, all available ranks of configuration log file are in configuration file LogLevel.config: Verbose, Event, Problem, Error, Fatal, and be provided with and be greater than or equal to the level conditions of Event rank for needing to satisfy, this level conditions that need satisfy is in aforementioned all available levels.After the system start-up, from configuration file LogLevel.config, read this level conditions, in the process that forms log record, have only the daily record of current record to be superior to or equal this other log record of Event level, be Event, Problem, Error, other log record of Fatal level just can be written in the journal file.In other words, in this example, other log record of Verbose level will can not be written in the journal file.
In practice, described default level conditions can be provided with arbitrarily according to current needs by those skilled in the art, below enumerates several schemes and specifies.
Scheme one: default first rank, determining to be greater than or equal to other daily record rank of the described first order is the rank that satisfies condition;
Specifically can be referring to situation shown in the last example.Preferably, described first rank is the minimum rank that system allows, i.e. the minimum rank of not influence system operation, as above the Verbose rank shown in the example.
This programme can effectively reduce the shared storage space of journal file.In experimenting, we find out that: all be written under the situation of journal file at other log information of all grades, the journal file that system every day (24 hours) produces takies the about 100MB of storage, and the hard-disk capacity of a 50GB will have been consumed in 500 days; After having disposed all time low rank, owing to shielded and little other information of lowermost level of system's operational relation, so system produces the only about 60MB of journal file every day, the capacity of same 50GB will have been consumed after 833 days, compare with the former, prolonged more than 300 day, effect is very remarkable.
Scheme two: default second level, determining to be less than or equal to other daily record rank of the described first order is the rank that satisfies condition;
Suppose that all available ranks of journal file are: Verbose, Event, Problem, Error, Fatal, the level conditions of Error rank for needing to satisfy is less than or equal in setting, after the system start-up, from configuration file LogLevel.config, read this level conditions, in the process that forms log record, have only the daily record rank of current record to be less than or equal to other log record of Error level, be Verbose, Event, Problem, other log record of Error level just can be written in the journal file, and other log record of Fatal level will can not be written in the journal file.
Scheme three: the pre-set level interval, determine that the daily record rank in described level interval is the rank that satisfies condition.
Suppose that all available ranks of journal file are: Verbose, Event, Problem, Error, Fatal, level interval is set for be clipped to the level conditions of Error rank from the Event level for needing to satisfy, after the system start-up, from configuration file LogLevel.config, read this level conditions, in the process that forms log record, have only the daily record rank of current record to be the Event in interval, Problem, Error rank, this log record just can be written in the journal file, and interval outer Verbose rank and other log record of Fatal level will can not be written in the journal file.
Present embodiment passes through a kind of like this mode of flexible configuration just, not only reduced the storage space that journal file takies, make that also the management of daily record is more flexible, thereby guarantee that information major part stored in journal file is valuable information, for the operation of user inquiring daily record, also help the raising of user's operating efficiency.
Certainly, it all is feasible that those skilled in the art dispose described daily record rank and pre-set level condition arbitrarily according to actual conditions, and only as example, the present invention need not to make qualification to aforesaid way to this.
