Step 303, judges whether the load of described system is greater than default Flow Control threshold value.
After determining the current load condition of system, can control the quantity of the log information that is sent to log task message queue according to the load condition of system.Therefore, first can judge whether the load of described system is greater than default Flow Control threshold value, if so, perform step 304; If not, perform step 305.
For described Flow Control threshold value, those skilled in the art are according to the practical experience setting of being correlated with, and it is 70% that described Flow Control threshold value is for example set, etc., the embodiment of the present invention is not limited this.
Step 304, reduction is sent to the quantity of the log information of described log task message queue.
Be greater than default Flow Control threshold value if judge the load of described system, can illustrate that now system loading is higher, if there is again a large amount of log informations to be sent to log task message queue, will cause system loading further to promote, consume more memory source.Therefore, in this kind of situation, in the embodiment of the present invention, can reduce the quantity of the log information that is sent to described log task message queue, to alleviate the impact that system loading is caused.
In a preferred embodiment of the present invention, this step 304 can comprise: adopt overall control mode to reduce the quantity of the log information that is sent to described log task message queue; And/or, adopt balanced control mode to reduce the quantity of the log information that is sent to described log task message queue; And/or, adopt module controls mode to reduce the quantity of the log information that is sent to described log task message queue; And/or, adopt meticulous control mode to reduce the quantity of the log information that is sent to described log task message queue.Also be, in this step 304, can from above-mentioned overall control mode, balanced control mode, module controls mode and meticulous control mode, select any or select any two kinds of modes combination wherein or select any three kinds of modes combination wherein or select whole four kinds of mode combinations, completing the process of the quantity that reduces the log information that is sent to described log task message queue.
Below, respectively above-mentioned four kinds of control modes are introduced.
1, overall control mode
In the embodiment of the present invention, the step that adopts overall control mode to reduce the quantity of the log information that is sent to described log task message queue specifically can comprise following sub-step:
Sub-step a1, compares the load of described system and the default Flow Control upper limit and Flow Control lower limit;
In the embodiment of the present invention, can set in advance a Flow Control upper limit and a Flow Control lower limit, whether will send log information to log task message queue for controlling.More balanced in order to guarantee system loading, between two numerical value of the above-mentioned Flow Control upper limit and Flow Control lower limit, there is certain intervals, certain buffer zone is set, in the time that system loading is positioned at buffer zone, will keep current state.For example, can arrange in Flow Control and be limited to 80%, under Flow Control, be limited to 60%, between 60%-80%, be buffer zone.
If the load of described system is greater than the default Flow Control upper limit, carry out sub-step a2; If the load of described system is less than default Flow Control lower limit, carry out sub-step a4; If the load of described system is more than or equal to default Flow Control lower limit, and be less than or equal to the default Flow Control upper limit, carry out sub-step a6.
In a preferred embodiment of the present invention, can also in above-mentioned daily record quantity control module, a log recording state be set, it can comprise opening and closed condition, in the time that daily record recording status is opening, represent to allow the log information that each functional module is sent to be sent in log task message queue, in the time that daily record recording status is closed condition, represent not allow the log information that just each functional module sends to be sent in log task message queue, therefore can whether send log information to log task message queue according to this log recording state control.
Sub-step a2, judges current log recording state;
Prescribe a time limit when the load of described system is greater than in default Flow Control, can illustrate that system loading is now comparatively nervous, therefore, in this kind of situation, will shield the log information that each functional module sends.Due to the monitoring of system loading state is carried out in real time or regularly, therefore before processing, this may revise log recording state.Therefore, in the embodiment of the present invention, can first judge current log recording state, opening if, carries out sub-step a3; Closed condition if, carries out sub-step a6.
Sub-step a3, is revised as closed condition, gives up the log information that described each functional module sends;
If be greater than the default Flow Control upper limit at the load of described system, and current log recording state is opening, to be now closed condition by described log recording status modifier, give up the log information that described each functional module sends, the log information of refusing described each functional module to send is sent in log task message queue.
Sub-step a4, judges current log recording state;
Prescribe a time limit when the load of described system is less than under default Flow Control, can illustrate that system loading is now comparatively idle, therefore, in this kind of situation, the log information that each functional module can be sent be sent in log task message queue.First can judge current log recording state, closed condition if, carries out sub-step a5; Opening if, carries out sub-step a6.
Sub-step a5, is revised as opening, and the log information that described each functional module is sent is sent to described log task message queue.
If be less than default Flow Control lower limit at the load of described system, and when current log recording state is closed condition, will be now opening by described log recording status modifier, and the log information that described each functional module is sent be sent to described log task message queue.
Sub-step a6, keeps current log recording state.
Be more than or equal to default Flow Control lower limit if judge the load of described system in sub-step a1, and be less than or equal to the default Flow Control upper limit, can keep current log recording state.If current log recording state is opening, the log information described each functional module being sent is sent to described log task message queue; If current log recording state is closed condition, give up the log information that described each functional module sends.
If judging current log recording state in sub-step a2 is closed condition, can keep log recording state is closed condition, give up the log information that described each functional module sends, the log information of refusing described each functional module to send is sent in log task message queue.
If judging current log recording state in sub-step a4 is opening, can keep log recording state is opening, and the log information that described each functional module is sent is sent in log task message queue.
By overall control mode, can in the time that the load of system be very high, (be greater than on flow and prescribe a time limit), stop sending log information to log task message queue, the quantity that is about to the log information that is sent to described log task message queue is reduced to zero, thus the burden of mitigation system.
2, balanced control mode
In the embodiment of the present invention, the step that adopts balanced control mode to reduce the quantity of the log information that is sent to described log task message queue specifically can comprise following sub-step:
Sub-step b1, obtains the token quantity in idle condition in system;
Token is a kind ofly can control the special frames that node occupies media, with distinguishes data frame and other control frames.Token method is called again isarithmic, the basic thought of token method is: the flag information (codes of one or more binary digits compositions) that uniqueness is called token sends to another node from a node, only has the node of the acquisition token packets of information of just having the right to send.In the time that a node is ready for sending packets of information, first to wait for the arrival of token, in the time the token that his token of process is idle condition being detected, can capture this token, and the state of this token is set to seizure condition, then send information take " frame " as unit to destination node; Information is with token to destination node, and destination node is by information reproduction, and token continues to go in ring and turns back to sending node, and at this moment transmitting station just discharges the token of capturing, and token becomes idle condition again.If all tokens are seizure condition, now wish that the node of transmission information will wait for the appearance of idle condition token.
In the system at described system journal place, can also comprise multiple tokens, the state of described token can comprise two kinds of idle condition and seizure conditions.In the embodiment of the present invention, can control the quantity of the log information that is sent to described log task message queue according to token.First, can obtain the token quantity in idle condition in described system, control according to this token quantity.
It should be noted that, before above-mentioned sub-step b1, can also judge and in system, whether have the token in idle condition, if existed, carry out sub-step b1, if there is no, temporarily do not process (temporarily stop send to log task message queue log information), until carry out sub-step b1 while there is the token in idle condition.
Sub-step b2 chooses the log information with the described token number in idle condition from described log information;
Getting in system after the token quantity in idle condition, can send log information to log task message queue according to the quantity of this token.Specifically can from described log information, choose the log information with the described token number in idle condition.
In a preferred embodiment of the present invention, described log information is except comprising log content, can also comprise the transmitting time of this log information, therefore in the embodiment of the present invention, can from described log information, choose according to the transmitting time of described log information the log information with the described token number in idle condition.Therefore, this sub-step b2 specifically can comprise: according to the sequencing of described transmitting time, described log information is sorted; First log information from sequence starts, and chooses the log information with the described token number in idle condition.
Certainly, can also adopt other information from described log information, to choose and the log information of the described token number in idle condition, the embodiment of the present invention is not limited this.For example, can also for each log information, priority be set in advance, in described log information, can also comprise the priority that this log information is corresponding, in such cases, this sub-step b2 specifically can comprise: according to the sequence of described priority, described log information is sorted; First log information from sequence starts, and chooses the log information with the described token number in idle condition.
Sub-step b3, is sent to described log task message queue by the log information of choosing, and remaining log information is carried out to buffer memory.
After the log information of choosing from described log information with the described token number in idle condition, the log information of choosing can be sent to described log task message queue by the described token in idle condition, and remaining log information is carried out to buffer memory.
After the log information of choosing is successfully sent to described log task message queue by the token in idle condition, will discharge the shared token of this log information, the shared token of this log information will be converted to idle condition from seizure condition.For the residue log information of buffer memory after sequence, be successfully sent to by waiting for the token that the log information of log task message queue discharges, be sent to log task message queue by the token in idle condition after being released.
The above-mentioned sub-step b1-sub-step b3 execution that can circulate, after sub-step b3 executes, can return to step b1 and obtain the token quantity in idle condition in system, if now there is the token of idle condition, can from the log information of buffer memory, choose and the log information of the current token number in idle condition (this choose process can with reference to above-mentioned sub-step b2), finally the log information of choosing is sent to described log task message queue by the described token in idle condition.
By balanced control mode, can be in the time that the load of system be higher (while being greater than default flow threshold), by the quantity of the log information that is sent to described log task message queue is reduced to identical with the token quantity in idle condition in system, thereby guarantee the equilibrium of log recording, the burden of mitigation system.
3, module controls mode
In the embodiment of the present invention, the step that adopts module controls mode to reduce the quantity of the log information that is sent to described log task message queue specifically can comprise following sub-step:
Sub-step c1, the quantity of the log information that interior described each functional module of unit interval of adding up respectively default sends;
In the embodiment of the present invention, the quantity of the log information sending due to each functional module is unbalanced, therefore can also adopt module controls, for example, only the more functional module of log information sending is carried out to Flow Control, and can not affect other functional modules.
Along with the operation of system, the quantity of the log information that each functional module sends will be accumulated, therefore in embodiments of the present invention, the quantity of the log information that each functional module in the statistical unit time sends is to send the highest functional module of log information frequency in order to find, if the log information quantity that this functional module sends within the unit interval is greater than default amount threshold, gives up the log information that this functional module sends.For the concrete numerical value of described unit interval, those skilled in the art adjust setting according to concrete system, for example, can be set be 10 minutes, 30 minutes, 1 hour the described unit interval etc., and the embodiment of the present invention is not limited this.
The quantity of the log information that interior described each functional module of unit interval that first, can add up respectively default sends.In a preferred embodiment of the present invention, described log information can also comprise the functional module mark that sends this log information, therefore, this sub-step c1 specifically can comprise: add up respectively the quantity that comprises the log information of same functional module mark in default unit interval, identify the quantity of the log information that corresponding functional module sends using described quantity as described same functional module.
For example, described system comprises 3 functional modules, its mark is respectively 1,2,3, can add up respectively the quantity that comprises the log information of mark 1, mark 2, mark 3 in default unit interval, the quantity of the log information that the quantity that comprises the log information that identifies 1 is sent as functional module 1, the quantity of the log information that the quantity that comprises the log information that identifies 2 is sent as functional module 2, the quantity of the log information that the quantity that comprises the log information that identifies 3 is sent as functional module 3, etc.
It should be noted that, for the quantity of the log information that in the statistical unit time, each functional module sends, can also in the daily record quantity control module shown in Fig. 1, a timer be set, can add up while starting to arrive the default unit interval to the time from timing, the quantity of the log information that in this unit interval, each functional module sends, for concrete process, the embodiment of the present invention is discussed no longer in detail at this.
Sub-step c2, if the quantity of the log information that certain functional module sends is greater than default amount threshold, gives up the log information that this functional module sends, and remaining log information is sent to described log task message queue.
In the embodiment of the present invention, can set in advance an amount threshold, and the quantity of the log information that in the default unit interval of above-mentioned statistics, each functional module sends is compared with described amount threshold respectively, if the quantity of the log information that certain functional module sends is greater than default amount threshold, can illustrate that the log information that this functional module sends within the default unit interval is more, in this kind of situation, can give up the log information that this functional module sends, and remaining log information is sent to described log task message queue, the quantity that described remaining log information is the log information of other transmission is less than or equal to the log information of the functional module transmission of default amount threshold.Wherein, the step of giving up the log information that this functional module sends specifically can comprise: give up the log information that comprises this functional module mark.In said process, if exist the quantity of the log information that multiple functional modules send within the default unit interval to be greater than default amount threshold, can give up the log information that the plurality of functional module sends.
