As shown in Figure 1, comprise the steps according to the collocation method of the server of the embodiment of the present invention.
Step S101, the performance data of each server in real-time monitoring system.
In one embodiment of the invention, be server deploy each in system monitor client, periodically the performance data of server be sent to special data collection server, so just the performance data collection of Servers-all in system can be got up.In addition, because the server in system can be deployed in different machine rooms, there is the restriction of bandwidth in the network across machine room, so all can dispose data collection server at different machine rooms, to improve system effectiveness.
Wherein, the performance data of server can comprise: system cache size, system cache size, residue physical memory, physical memory total amount, the CPU of User space, the CPU of systematic thinking way, the CPU waited for, overall disk utilization rate, all network interface card influent stream amounts and, all network interface card outflows and, overall disk utilization rate, per second completing reads I/O equipment number of times, per second completing writes I/O equipment number of times, per secondly read K byte number, per secondly write K byte number, the size of data of average each equipment I/O operation, average I/O queue, IOQ length, the stand-by period of average each equipment I/O operation, percent how many time was had for I/O operation etc. on average per second.
Should understand, although obtain all properties data of each server when monitoring, but choice for use certain or some performance data can obtain corresponding index as required when concrete process, what such as compare concern for the product of Distributed Calculation is the utilization factor of CPU, and the relevant performance data of CPU such as the CPU of User space, the CPU etc. of systematic thinking way so can be used to calculate when data processing.
Step S102, calculate the server resource utilization factor of each product line according to the performance data of each server, wherein each product line comprises multiple server.
In system, the quantity of server is very many, and every day, data volume to be processed was very large.Typically do not need all historical datas of preserving Servers-all, the deposit data of every station server is in RRD file for this reason, as long as every day, timing processed.And in order to embody the true utilization rate situation of server, the single index of every day statistics can adopt every 10s to gather a secondary data, per hour carry out once average, in this, as the base unit of statistics.Simultaneously, this is also the peak-utilization situations in order to obtain server, because data in 10s may be the interim tasks carrying of server, and can not the overall operation situation of representative server, and the peak continuing a hour also just can the service condition of response service device.
Particularly, Fig. 2 is the schematic diagram of the method for the server resource utilization factor of each product line of calculating of one embodiment of the invention.As shown in Figure 2, first, periodically calculate the resource utilization of each server according to the performance data of server received and the statistical model of presetting, such as every 10s calculates once.Then, statistical average is carried out to obtain the resource utilization mean value of each server within certain time period to the resource utilization of each server of multiple time point, such as, obtains resource utilization/8640 of unit mean value=each time point of ∑ unit every day.Then, then obtain the resource utilization mean value of product line within certain time period according to the number of servers in unit mean value and product line, what such as obtain product line every day average=each unit of ∑ works as day average/unit quantity.Again then, according to the resource utilization mean value of product line within certain time period, the resource utilization mean value of whole timing statistics can also be obtained, as timing statistics mean value=∑ product line every day average/statistics number of days of product line.
The ASSOCIATE STATISTICS of the maximal value of the server resource utilization factor of product line and the processing mode of above-mentioned mean value similar, be not described in detail herein.In addition, except the server resource utilization factor calculating each product line, the resource utilization of subclassification, department etc. can also be calculated.
More specifically, in one embodiment of the invention, can according to system cache size buffer, system cache size cache, residue physical memory free and physical memory total amount total, by the systematic thinking way memory usage MEM of following formulae discovery server

According to all network interface card influent stream amounts and, all network interface card outflows and, totally pass in and out flow by all network interface cards of following formulae discovery server,
All network interface cards totally pass in and out flow=all network interface card influent stream amounts and+all network interface card outflows and.
Step S103, judges whether the resource utilization of each product line meets default resource utilization standard.
Should understand, oneself distinctive application scenarios and system architecture mode all can be had for different product lines, the distribution of calculated amount and different to the requirement of redundance, for this specifies different performance index to different product lines, such as, product for Distributed Calculation then requires that the utilization factor of CPU reaches particular requirement; Application for storage-type then requires that the use amount of disk reaches particular requirement.
Particularly, Fig. 3 be one embodiment of the invention judge whether server resource utilization factor reaches the process flow diagram of calibration method.As shown in Figure 3, the method comprises the steps.
Step S311, judges the type of product line.

Step S312, according to the type of product line, the resource utilization value pay close attention to this product line type and the concern resource utilization threshold corresponding to this product line type compare, and judge whether the threshold value of the resource utilization of this concern is greater than corresponding resource utilization threshold.
Such as, for the product of Distributed Calculation, the resource utilization paid close attention to is cpu busy percentage, and its corresponding cpu busy percentage threshold might be set is 75%; For the product of back-end data process, the resource utilization paid close attention to is disk use amount, and its corresponding disk use amount can be set as 70%.
Step S313, if the resource utilization value paid close attention to is greater than corresponding resource utilization threshold, then determines that the resource utilization of this product line meets standard.
Step S314, if the resource utilization value paid close attention to is not more than corresponding resource utilization threshold, then determines that the resource utilization of this product line is not up to standard.
Should be understood that above-mentioned example is only schematic example, be not limited to the present invention.Those skilled in the art also can adopt other mode to judge, and whether the server resource utilization factor of product line is up to standard.Such as, identical first resource utilization factor standard can be set to all product lines, after judging that certain product line does not meet this first resource utilization factor standard, judge whether this product line belongs to the service of specific type again, if so, then optimize first resource utilization factor standard, re-start judgement.These modifications and variations all should be included in protection scope of the present invention.
Step S104, if so, then increases the number of server in product line.
If the server resource utilization factor of product line is up to standard, then mean that the utilization factor of the server in existing product line is saturated, when business demand increases, the quantity of existing server possibly cannot meet business demand, therefore needs the number increasing server to ensure that product line can meet the business demand increased.
Step S105, if not, then keeps the invariable number of server in product line.
If the server resource utilization factor of product line is below standard, then mean that the server in existing product line is not fully utilized, therefore now without the need to increasing the number of server in product line, as long as improve the utilization factor of server in product line and the demand of guaranteed service growth.
