Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other Embodiment shall fall within the protection scope of the present invention.
The embodiment of the present invention can be used for a kind of operation system, and the operation system includes at least one front end virtual machine； At least one front end virtual machine occupies a part of operation system resource in the operation system, and for receiving and processing The data that user equipment is sent to the operation system, the operation system resource, which includes at least, supports at least one front end Virtual machine computing resource and storage resource required when running.Such as：One kind as shown in Figure 1 applies virtualization technology and bears The operation system for carrying balancing technique, includes at least：Virtual platform (Virtualization Platform), management platform (Management Platform), load balancing (Load Balancing) change platform.
Include application packet inside virtual platform, application packet be by multiple virtual robot arms at one answered for supporting The virtual machine set run with program is used directly to support that the virtual machine that some application program is run can in the set To be referred to as the front end virtual machine of the application program.Pass through the Network Performance Monitor in virtual platform, timing acquisition application packet In be marked as the performance parameter of front end virtual machine, the performance parameter of acquisition is sent to the pipe of management platform by Network Performance Monitor Module is managed, and analyzes the loading level of application program according to performance parameter by management module, further according to set resource pool Management strategy determine the quantity of front end virtual machine for needing to increase and decrease for the loading level of front end virtual machine, and need to increase and decrease Business interface quantity, wherein the management strategy of resource pool includes：Elastic telescopic group multiplexing parameters, resource contention detection, money Resource reclaim and resource pool when the deficiency of source reserve the setting of resource, are increased and decreased by interface 1 by load balancing module load later The business interface for equalizing respective numbers on platform increases and decreases respective numbers on virtual platform by virtual machine module by interface 2 Front end virtual machine, it is and increased front end virtual machine is corresponding with increased business interface, then will be answered by load balancing module It is distributed on the front end virtual machine in virtual platform with the service request generated in program operation process, to complete load point Send out function.
As shown in Figure 1a, the method flow of the embodiment of the present invention may include：
101, the performance parameter of at least one front end virtual machine is detected.
Wherein, the performance parameter is used to reflect the loading level of at least one front end virtual machine, the performance ginseng Number can be the utilization rate of CPU, information exchange frequency or other specific parameters.
Such as：The Network Performance Monitor being present in virtual platform detects the utilization rate of the CPU of front end virtual machine A.If The utilization rate of CPU is higher than preset threshold value, then illustrates that front end virtual machine A has run many programs on this time, bears It carries larger；If the utilization rate of CPU is less than preset threshold value, illustrate that front end virtual machine A has been run very on this time Few program, load are smaller.
Again for example：The Network Performance Monitor being present in virtual platform detects the information exchange frequency of front end virtual machine A. If information exchange frequency is higher than preset threshold value, illustrate that front end virtual machine A has carried out multiple information on this time Interaction, load are larger；If information exchange frequency is less than preset threshold value, illustrate front end virtual machine A on this time Few information exchange is carried out, load is smaller.
Again for example：The Network Performance Monitor being present in virtual platform detect the CPU of front end virtual machine A utilization rate and Information exchange frequency.If the utilization rate and information exchange frequency of CPU are all higher than preset threshold value, illustrate front end virtual machine A has run many programs on this time, and has carried out multiple information exchange, and load is larger；If the utilization rate and letter of CPU Breath frequency of interaction is below preset threshold value, then illustrates that front end virtual machine A has run seldom program on this time, And few information exchange is carried out, load is smaller.
102, it according to the performance parameter of at least one front end virtual machine, executes for the front end in the operation system The Adjusted Option of virtual machine.
Wherein, the Adjusted Option is used to adjust the operation system for distributing to the virtual machine of the front end in operation system money Source, in order to which the operation system resource and at least one front end of distributing to the front end virtual machine in the operation system are virtual The loading level of machine matches, such as：Adjusted Option may include：Adjust the quantity and adjustment front end virtual machine of front end virtual machine Specification.When the performance parameter according at least one front end virtual machine, execute empty for the front end in the operation system After the Adjusted Option of quasi- machine, front end virtual machine is made to be adapted to the loading level after Adjusted Option.
Such as：On weekdays, the portfolio of enterprises mailbox service system is in peak value, and mailbox service system can root The quantity for increasing front end virtual machine according to self-demand extenuates front end virtual machine due to actual negative to spend the peak value of portfolio Loading capability is too low to cause business execution efficiency to decline；In the legal festivals and holidays, the portfolio of enterprises mailbox service system is restored To after average level, mailbox service system can reduce the quantity of front end virtual machine according to self-demand, to keep front end virtual Machine need not be chronically at idle running or idle state, and extenuate front end virtual machine leads to the wasting of resources since actual loading ability is excessively high.
Again for example：Equal phase commuter rush hours before and after festivals or holidays, the portfolio for operation system of booking tickets are in peak value, business of booking tickets System can be that front end virtual machine distributes more hardware resource according to self-demand, to improve business processing speed, spend The peak value of portfolio, extenuate front end virtual machine causes business execution efficiency to decline since actual loading ability is too low；In non-passenger flow Peak period, after the portfolio recovery for operation system of booking tickets, ticket booking operation system can be front end virtual machine point according to self-demand With less hardware resource, lead to the wasting of resources since actual loading ability is excessively high to extenuate front end virtual machine.
The method of a kind of adjustment operation system resource based on virtual machine provided in an embodiment of the present invention, by analyzing business The operation system money of the front end virtual machine in the operation system is distributed in the performance parameter of front end virtual machine in system, adjustment Source, in order to the operation system resource for distributing to the front end virtual machine in operation system and at least one front end virtual machine Loading level matches.It is compared to the prior art, the front end virtual machine distributed in the operation system can be adjusted in real time Operation system resource, so that the load capacity of front end virtual machine is matched with current loading level.Therefore, it is virtual to extenuate front end Machine leads to the wasting of resources since actual loading ability is excessively high, and extenuates front end virtual machine and cause since actual loading ability is too low The problem of business execution efficiency declines.
In the present embodiment, it after the performance parameter for detecting at least one front end virtual machine, needs performance parameter It is compared with threshold value, and executes the Adjusted Option for the front end virtual machine in the operation system.Therefore, in such as Fig. 1 a institutes On the basis of the mode shown, step 102 can be implemented as 201-202 as shown in Figure 2：
201, judge whether the performance parameter of at least one front end virtual machine is less than first threshold or is more than the second threshold Value.
Wherein, the first threshold and the second threshold be according to the fixed empirical value of specific business, can be from for surveying The experience database of examination and record loading level obtains, or is set by technical staff.
If 202, the performance parameter of at least one front end virtual machine is less than first threshold or is more than second threshold, hold Adjusted Option of the hand-manipulating of needle to the front end virtual machine in the operation system.
Wherein, if the performance parameter of at least one front end virtual machine is more than or equal to first threshold and is less than or equal to second Threshold value is not dealt with then.
Such as：When the performance parameter of the front end virtual machine A detected is less than preset first threshold, or more than pre- When the second threshold first set, operation system is according to the actuality stage adjustment scheme of interior forward end virtual machine A.If front end virtual machine A's Performance parameter is less than first threshold, and loading level is smaller, then reduces the quantity of front end virtual machine A, or the hardware that distribution is less In resource to front end virtual machine A；If the performance parameter of front end virtual machine A is more than second threshold, loading level is larger, then before increasing The quantity of virtual machine A is held, or is distributed in more hardware resource to front end virtual machine A.
Again for example：Judge within a specified time, the rate of change of the performance parameter of at least one front end virtual machine Whether absolute value is more than or equal to pre-determined threshold, if the rate of change of the performance parameter of at least one front end virtual machine is absolute Value is more than or equal to pre-determined threshold, then executes the Adjusted Option for the front end virtual machine in the operation system；If it is described at least The absolute value of the rate of change of the performance parameter of one front end virtual machine is less than pre-determined threshold, then does not deal with.
When the absolute value of the rate of change of the performance parameter of the front end virtual machine A detected is more than or equal to pre-determined threshold, Operation system is according to the actuality stage adjustment scheme of interior forward end virtual machine A.If the rate of change of the performance parameter of front end virtual machine A is Nonnegative value, and more than or equal to pre-determined threshold when or front end virtual machine A performance parameter rate of change be negative value and less than etc. When the negative value of pre-determined threshold, load rapidly increases, then increases the quantity of front end virtual machine A, or the hardware money that distribution is more In source to front end virtual machine A；If the rate of change of the performance parameter of front end virtual machine A is nonnegative value, and is less than or equal to pre- gating When in limited time or the rate of change of the performance parameter of front end virtual machine A is negative value and is more than or equal to the negative value of pre-determined threshold, load It rapidly reduces, then reduces the quantity of front end virtual machine A, or distribute in less hardware resource to front end virtual machine A.
A kind of method of adjustment operation system resource based on virtual machine provided in an embodiment of the present invention, at least according to judgement Whether the performance parameter of one front end virtual machine is less than first threshold or is more than second threshold, executes before being directed in operation system The Adjusted Option of virtual machine, adjustment is held to distribute to the operation system resource of the front end virtual machine in the operation system, in order to Distribute to the loading level of the operation system resource and at least one front end virtual machine of the front end virtual machine in operation system Match.It is compared to the prior art, performance parameter that can be according at least one front end virtual machine and first threshold and second The magnitude relationship of threshold value adjusts the quantity and specification of front end virtual machine in real time, make the load capacity of front end virtual machine with it is current Loading level matches.
By judging the magnitude relationship of the performance parameter and first threshold and second threshold of at least one front end virtual machine, hold Adjusted Option of the hand-manipulating of needle to the front end virtual machine in operation system.Therefore, front end virtual machine is extenuated due to actual loading ability mistake Height leads to the wasting of resources, and extenuate front end virtual machine cause since actual loading ability is too low business execution efficiency decline ask Topic.
In the present embodiment, it after the performance parameter for detecting at least one front end virtual machine, needs performance parameter It is compared with threshold value, the front end virtual machine being currently running by closing a part, and recycles pent front end virtual machine Operation system resource alternatively, deleting the front end virtual machine that a part is currently running, and recycles the industry of deleted front end virtual machine Business system resource；And pent front end virtual machine is opened, alternatively, the front end virtual machine of specified quantity is established, to execute For the Adjusted Option of the front end virtual machine in the operation system.Therefore, on the basis of mode as shown in Figure 2, step 201-202 can be implemented as 301-306 as shown in Figure 3：
301, judge whether the performance parameter of at least one front end virtual machine is less than first threshold.
If 302, the performance parameter of at least one front end virtual machine is less than first threshold, closes a part and transporting Capable front end virtual machine, and recycle the operation system resource of pent front end virtual machine.
Alternatively,
303, the front end virtual machine that a part is currently running is deleted, and recycles the operation system of deleted front end virtual machine Resource.
Such as：When the performance parameter of the front end virtual machine A detected is less than first threshold, before operation system is according to inside The present situation for holding virtual machine A, is adjusted the front end virtual machine inside operation system.Close the front end virtual machine B being currently running With front end virtual machine C, or delete the front end virtual machine B that is currently running and front end virtual machine C, and recycle front end virtual machine B and The operation system resource that front end virtual machine C is occupied.
Again for example：It is described default to judge whether the rate of change of the performance parameter within the specified time is less than or equal to The negative value of thresholding, if the rate of change of the performance parameter is less than or equal to the negative of the pre-determined threshold within the specified time Value then closes the front end virtual machine that a part is currently running, and recycles the operation system resource of pent front end virtual machine, or Person deletes the front end virtual machine that a part is currently running, and recycles the operation system resource of deleted front end virtual machine.
When detecting that the rate of change of within a specified time performance parameter is less than or equal to the negative value of pre-determined threshold, business system System is adjusted the front end virtual machine inside operation system according to the present situation of interior forward end virtual machine A.What closing was currently running Front end virtual machine B and front end virtual machine C, or the front end virtual machine B being currently running and front end virtual machine C is deleted, and before recycling The operation system resource that end virtual machine B and front end virtual machine C is occupied.
304, judge whether the performance parameter of at least one front end virtual machine is more than second threshold.
If 305, the performance parameter of at least one front end virtual machine is more than second threshold, pent front end is opened Virtual machine.
Alternatively,
306, the front end virtual machine of specified quantity is established.
Such as：When the performance parameter of the front end virtual machine A detected is more than second threshold, before operation system is according to inside The present situation for holding virtual machine A, is adjusted the front end virtual machine inside operation system.Open pent front end virtual machine B and Front end virtual machine C, or establish the front end virtual machine of specified quantity.
Again for example：It is described default to judge whether the rate of change of the performance parameter within the specified time is less than or equal to The negative value of thresholding is opened if the rate of change of the performance parameter is more than or equal to the pre-determined threshold within the specified time Pent front end virtual machine is opened, alternatively, establishing the front end virtual machine of specified quantity.
When detecting that the rate of change of within a specified time performance parameter is less than or equal to the negative value of pre-determined threshold, business system System is adjusted the front end virtual machine inside operation system according to the present situation of interior forward end virtual machine A.Open it is pent before Virtual machine B and front end virtual machine C is held, or establishes the front end virtual machine of specified quantity.
It should be noted that 304-306 can be first carried out in figure 3,301-303 is executed afterwards.
A kind of method of adjustment operation system resource based on virtual machine provided in an embodiment of the present invention, at least according to judgement Whether the performance parameter of one front end virtual machine is less than first threshold or is more than second threshold, executes before being directed in operation system The Adjusted Option of virtual machine is held, the performance parameter of the front end virtual machine in operation system is analyzed, increase or reduces front end is virtual The quantity of machine, the operation system resource of the front end virtual machine in the operation system is distributed in adjustment, in order to distribute to business The operation system resource of front end virtual machine in system and the loading level of at least one front end virtual machine match.It compares Compared with the prior art, can be closed with first threshold and the size of second threshold according to the performance parameter of at least one front end virtual machine System adjusts the quantity of front end virtual machine, the load capacity of front end virtual machine is made to match with current loading level in real time.
By judging the magnitude relationship of the performance parameter and first threshold and second threshold of at least one front end virtual machine, close The front end virtual machine that a part is currently running is closed, and recycles the operation system resource of pent front end virtual machine, alternatively, deleting The front end virtual machine that a part is currently running, and recycle the operation system resource of deleted front end virtual machine；And open quilt The front end virtual machine of closing, alternatively, the front end virtual machine of specified quantity is established, it is empty for the front end in operation system to execute The Adjusted Option of quasi- machine.Therefore, extenuate front end virtual machine leads to the wasting of resources since actual loading ability is excessively high, and before extenuating The problem of end virtual machine causes business execution efficiency to decline since actual loading ability is too low.
