Referring to Fig.1, the occupancy of the occupancy acquisition methods first embodiment of processor of the present invention, the processor obtains
Method includes:
Step S10 obtains baseline Message processing duration.
Simulator creates baseline message, and baseline message is sent to the forwarding scheduler module in processor, in processor
Forwarding scheduler module processing baseline message handling duration be baseline Message processing duration.
Use the handling duration that baseline message is obtained using the crystal oscillator clock in physical processor as benchmark clock.Specifically,
Start timing (T when simulator triggers out baseline message1), after the completion of the processing of the forwarding process of baseline message, terminate timing
(T2), T1With T2Between time difference be baseline message handling duration.That is, baseline Message processing duration Tstd=T2-T1.Wherein, may be used

Step S20 obtains baseline Message processing amount in the calculating cycle according to the baseline Message processing duration.
The crystal oscillator clock is used to determine the beginning and ending time point of calculating cycle simultaneously.According to the duration (T of calculating cycleload)
With baseline Message processing duration (Tstd), the treating capacity that baseline message is capable of handling in a calculating cycle can be calculated, i.e.,

Literary treating capacity), thus according to the quantity of the baseline message of actual treatment in calculating cycle and the theoretical baseline report being capable of handling
Literary treating capacity can accurately calculate the occupancy of processor, improve efficiency and accuracy that processor occupancy calculates.
For example, presetting as baseline message using IPV4 message and calculating cycle TloadIt is 1 second.When VM is powered on, at physics
The crystal oscillator clock of device is managed as reference clock source.It triggers simulator and sends IPV4 message, record moment T1；It forwards at scheduler module
After the completion of managing the IPV4 message, simulator is sent back, records moment T2；According to formula Tstd=T2-T1Obtain baseline Message processing
Shi Changwei 5*10-7Second.Then, baseline Message processing amount is Num in calculating cycletotal=Tload/Tstd=1/5*10-7=2*106
It is a, i.e. 2*10 is capable of handling in a calculating cycle6A baseline message.
Weighted value β (ipsec)=10, nat business weighted value β (nat)=2, IPV4 message of default ipsec business
Weighted value is β (IPV4)=1.In server course of normal operation, gets and forward scheduler module coprocessing in calculating cycle
10000 IPV4 messages, 8000 ipsec messages, 5000 nat messages.It can be obtained calculating week according to different business weight
Total business Message processing amount in phase are as follows:
Counterstd,i=10000*1+8000*10+5000*2=105It is a.
Therefore, the occupancy of processor are as follows:
Loadi=Counterstd,i/Numtotal,i* 100%=105/(2*106) * 100%=5%.
In the present embodiment, baseline message is handled using the processor, obtains baseline Message processing duration, and then according to base
Report from a liner text handling duration obtains the treating capacity of the baseline message in a calculating cycle；In processor course of normal operation, obtain
The total business Message processing amount handled in calculating cycle is taken, using total business Message processing amount combination baseline Message processing amount, meter
Calculate the occupancy of the processor in calculating cycle.The service message treating capacity of actual treatment in calculating cycle is converted to place
The quantity (total business Message processing amount) for managing baseline message, thus according to the quantity of the baseline message of actual treatment in calculating cycle
And the theoretical baseline Message processing amount being capable of handling, the occupancy of processor can be accurately calculated, processor is improved and occupies
The efficiency and accuracy that rate calculates.
Further, the occupancy acquisition methods second embodiment of processor of the present invention is based on above-mentioned first embodiment, more
New baseline Message processing duration.
In virtualized environment, the hardware money such as the physical processor (CPU) of server, fast cache storage area (CACHE)
Source is shared to be used, and when handling different business message, the handling duration of baseline message may become virtual processor
Change, in the embodiment of the present application, when the processor for needing to calculate occupancy is virtual processor, timing updates at baseline message
Duration is managed, to ensure that calculated occupancy is more accurate.
Specifically, using the crystal oscillator clock of the physical processor of server as reference clock, in virtual server run mode
Shi Qiyong timer arrangement, timing cycle arrive, and control simulator creates baseline message, and the baseline message is sent to processing
Device obtains the handling duration that virtual processor handles the baseline message.It, can root by timing adjustment baseline Message processing duration
Reflect the more true processing capacity of virtual server according to the service condition of server physical resource, so that virtual server accounts for
It is calculated with rate more accurate.
For example, setting handling duration of the timing cycle of timer to update a baseline message after 10 seconds, 10 seconds, use
The occupancy of the new subsequent calculating cycle inner treater of baseline Message processing duration calculation.
In the present embodiment, tested virtual processor is avoided in use, it is each in virtual machine virtual shared to make
It is limited with the hardware resource of physical cpu, cause the handling duration of virtual processor processing baseline message unstable, timing updates base
Report from a liner text handling duration improves the accuracy that the occupancy of virtual processor calculates.
Further, referring to Fig. 2, the occupancy acquisition methods 3rd embodiment of processor of the present invention is based on above-mentioned first
Or second embodiment, after the step S40, further includes:
Step S50, judges whether the occupancy is greater than the first preset threshold.
Step S60 generates prompt information, when the occupancy is greater than first preset threshold to prompt processor
Occupancy excess load.
In order to ensure the normal processing of data message, operation maintenance personnel is appropriate right when the practical occupancy of processor is excessive
Processor carries out dilatation.Therefore, when occupancy is greater than certain first threshold, prompt information is generated, client server is prompted to account for
With rate excess load.Specifically, alarm module is arranged in the processor, the first preset threshold is preset, is greater than the first threshold in occupancy
When value, alarm module will be prompted to information and be sent to network management device, be somebody's turn to do so that network management device is shown in display interface
Prompt information is convenient for the timely Risk-warning of operation maintenance personnel, after user knows the prompt, is the processing such as dilatation behaviour to the processor
Make.
In addition, the information such as the title of the processor, address and information on load are reported together with prompt information, for
Targetedly improve the performance of processor in family.
In addition, after continuing to test the occupancy of processor, when the occupancy of calculating cycle inner treater is pre- less than second
If when threshold value, sending control instruction to network management device, eliminating the prompt information.Wherein, second preset threshold is less than
First preset threshold.
For example, presetting the first preset threshold in alarm module takes 80%, the second preset threshold takes 65%.It is counted at i-th
When the occupancy for calculating processor in the calculation period is 85% (being greater than 80%), the prompt information of occupancy excess load is generated.?
The occupancy of jth (j > i) a calculating cycle is 50% (less than 65%), then eliminates the prompt information.
In the present embodiment, it when the occupancy for calculating calculating cycle inner treater is greater than the first preset threshold, generates
Prompt information prompts user processor occupancy excess load, the load condition of processor is presented to operation maintenance personnel, operation maintenance personnel
Treatment measures can be taken in time, ensure the normal processing and forwarding of data message.
Further, referring to Fig. 3, the occupancy acquisition methods fourth embodiment of processor of the present invention is based on above-mentioned first
To three any embodiments, after the step S60, further includes:
Step S70, judge the occupancy of the processor in the calculating cycle whether less than the second preset threshold,
In, second preset threshold is less than first preset threshold.
Step S80 updates the occupancy and is less than when the occupancy of the processor is less than second preset threshold
The number of second preset threshold.
Step S90, judges whether the number is greater than preset times
Step S100 eliminates the prompt information when the number is greater than preset times.
Prompt information is being generated, after prompting processor occupancy excess load, is being detected in next calculating cycle
When occupancy in processor calculating cycle is less than the second preset threshold, number is recorded, when number is greater than preset times, is shown
For the occupancy of multiple period inner treaters less than the second preset threshold, the occupancy of server is lower, without expanding processor
Appearance processing, which is eliminated.
For example, when preset times are set as 3 times, after detecting that occupancy is greater than the first preset threshold within the i-th period, the
When the occupancy that i+2, i+3, i+4 continuously detect in three calculating cycles is respectively less than the second preset threshold, prompt information is eliminated.
For the timely notice for realizing alarm, the gentle occupancy restored, detected in continuous multiple calculating cycles is alerted
When respectively less than the second preset threshold, the prompt information of excess load is just eliminated.
After prompt information generation, monitor that continuous 3 server occupancies calculating cycle (3 seconds i.e. continuous) is calculated
Occupancy is 63%, 64%, 61% respectively, respectively less than the second preset threshold of alarm clearing, and alarm module report and alarm restores
And respective processor information and load value information etc. are reported together.
In the present embodiment, prompt information is being generated, after prompting processor occupancy excess load, in next calculating
When detecting the occupancy in processor calculating cycle in the period less than the second preset threshold, number is recorded, when number is greater than in advance
If when number, showing the occupancy of multiple period inner treaters less than the second preset threshold, the occupancy of server is lower, without pair
Processor carries out dilatation processing, which is eliminated.
In addition, the embodiment of the present invention also proposes a kind of occupancy acquisition methods device of processor, as shown in figure 4, described
The occupancy acquisition device of processor includes: crystal oscillator clock 10, forwards scheduler module 20, occupancy computing module 30.
The handling duration of baseline message is obtained as reference clock using crystal oscillator clock 10, and detects rising for calculating cycle
