Step S41: calculating the ratio of the flow of first time period and the flow of second time period, the first time period with
The second time period is in period first time.Pass through year-on-year mode ratio calculated first.For calculating road flow accounting:
If it is X that 2 weeks Saturdays, which calculated the road top road Shi Suan ratio, before on October 1st, 20181, the same day on October 1st, 2018 calculation road
The top road Shi Suan ratio is X2, the ratio of the flow of the flow and second time period of first time period is X1/X2, extract phase
The journal file of period is answered to obtain corresponding calculation road ratio.For example, extracting at 11 points of Saturday of 2 weeks before on October 1st, 2018
Journal file, obtain and 11 count the road top road Shi Suan ratio.
Step S42: by the ratio multiplied by the flow of third period, the equipment under test is obtained in target time section
Flow is estimated, the third period and the target time section are in second time period.In this example, if state in 2019
It celebrates preceding 2 weeks Saturdays and calculates the road top road Shi Suan ratio as Y1, then speculate when the same day on October 1st, 2019 calculates road top
Calculation road ratio is X2/X1×Y1。
Step S43: by the traffic transformation of estimating for basic request list.In this example, several weeks before target time section
By way of being converted, vacuated log, being sorted, or the worthwhile road peak period flow of line is converted into base by the modes such as practical timing recording
The request list of the JSON format of plinth version, i.e., basic request list, the basis as construction test request list.
Step S44: according to the origin information and endpoint information in the traffic log before target time section, to the base
Origin information and endpoint information in plinth request list are replaced, and obtain preliminary allotment request list.
Step S45: the ratio in the request source in the adjustment preliminary allotment request list obtains secondary allotment request column
Table.In this example, each traffic source ratio in the preliminary allotment request list of adjustment: several main ratios to request source of adjustment
Example, is allowed to meet the component ratio in festivals or holidays (i.e. October 1).It is main that request source can be cell phone client, Web (webpage)
It stands, open platform, API (Application Programming Interface, application programming interface) interface etc..
Step S46: according to preset rules, the composition ratio of secondary allotment request list is adjusted, request list is estimated in acquisition.
Before step S41 execution, can be according to target time section the characteristics of, flow influence factor is estimated.For example, if target
Period is festivals or holidays, then according to festivals or holidays the characteristics of, estimate flow effect factor.According to flow effect factor, obtaining step
Composition ratio in the allotment rule and step S46 of secondary allotment in S45 deploys rule.In this example, secondary tune is adjusted
Ingredient with the other influences factor in request list.As recommended in the ratio with license plate, the distribution proportion of different editions, row
Ratio etc..And the request source for navigation module of driving is numerous, there is mobile phone terminal, PC (Personal Computer, personal computer)
End, open platform, api interface etc..Different data sources is also different to the pressure of the modules in server cluster.According to step
Request list is estimated in rapid S44-S46, acquisition, can be more nearly the actual conditions of target time section.
Step S47: according to preset request list composition ratio, verifying the request list of estimating, and obtains school
Test result.It obtains after estimating request list, needs to verify the composition ratio for estimating request list, guarantee test
Test request list meets expection, can simulate true target time section flow, meet with the characteristic of target time section.Example
Such as, October 1 was to estimate before volume test to the flow factor of this festivals or holidays festivals or holidays.Remote way when festivals or holidays
Navigation requests amount increases, and navigation requests total amount increases.It is verified according to the flow factor of festivals or holidays to request list is estimated.School
It when testing, is tested before progress vocabulary first, carries out the priori of test request list, the point mainly verified in preset test environment are as follows:
Calculate the distribution of road distance, accounting, the ratio of various traffic sources, the ratio with license plate of calculating road flow etc..Secondly vocabulary is carried out
Posteriority, environment carries out the posteriority of test request list, the index paid close attention at this time are as follows: the traffic transformation ratio of downstream module on line
Example, consumption of specific discharge CPU of downstream module etc..The ratio of single channel line, multi-route is also noted that under the scene of part, generally
In the case of multi-route be to the performance consumption of downstream calculation road module single channel line several times.
Step S48: according to the check results, the request list of estimating is adjusted, the test request is obtained
List.
Step S49: single computer room flow is cut into sky.
Step S410: single computer room is tested using test request list, and pays close attention to the indices of navigation system in real time, is seen
Examine the unusual condition that computer room crosses limit with the presence or absence of flow.
Step S411: evaluation test is as a result, carry out dilatation to single computer room according to test result.
Using similar step, volume test is carried out again to the computer room after dilatation, until capacity is met the requirements.In this hair
Express in example, capacity is met the requirements, and can be referred to that capacity is not less than and be estimated the sum of flow and pre- allowance.When dilatation, each computer room is pre-
The server for staying certain pre- allowance, such as meets N+1 redundancy, guarantees that flow can be switched to other machines after some computer room goes wrong
