Detailed Description
The following detailed description of specific embodiments of the invention refers to the accompanying drawings and the exemplary embodiments. The present invention may be variously modified and may include various embodiments. There is shown in the drawings embodiments which are presently preferred. These preferred embodiments do not limit other embodiments of the invention.
Referring to fig. 1, the present invention provides a traffic-based IT capacity prediction method, including the following steps:
s1: acquiring service volume data; and collecting historical traffic data of different services.
S2: screening a service scene; and screening out the traffic data and the time points required by meeting scene conditions according to the predicted service scene.
The module displays the property quantity characteristics of different services according to different IT capacity prediction targets, so that a user can select services and time points meeting conditions. For example, the predicted business scenario can be divided into different channels such as a bank counter, an internet bank or a mobile phone client. The number of passengers in the transportation industry, the number of patients in outpatient service or emergency service in hospitals and the like can be used. If the user wants to test whether the IT capacity of the counter channel can be supported during the peak period when the liabilities are issued, the user only needs to select the historical business volume of the counter channel when the liabilities are issued, and the business volume of other channels can be ignored.
The time point can be a working day, a release day of bank financing products, a gold or stock market fire explosion date, a Taobao Shuangelen network promotion date and other special dates, can also be a traffic and transportation peak such as national day, spring festival and the like, or a disease peak period of flu in autumn and winter, and the like, and the user can select the service and the date meeting the conditions.
S3, acquiring IT capacity data; historical data consumed by a background IT system, namely historical data of capacity resources such as IT application systems, computer servers, network equipment, storage equipment and the like related to services are collected.
S4: screening an IT capacity scene; and screening data in a stable time period range among the application system version, the system software version and the IT resource configuration.
The consumption of IT capacity is related to the traffic, but the consumption of IT capacity divided by the consumption of IT capacity of a single service is only related to the version of the IT application system and the underlying IT resources. Therefore, the embodiment screens the data of the version of the application system and the underlying IT resources within the unchanged time period range, and the data is used as the basis for analyzing the positioning and analysis of the IT capacity resources.
S5: and the data cleaning and noise reduction are realized by supplementing vacancy values to all the acquired traffic data and IT capacity data and cleaning to remove noise points so as to accurately calculate the data by adopting an intelligent algorithm.
The intelligent algorithm comprises an artificial intelligence algorithm, a big data algorithm, a time sequence algorithm, a linear regression algorithm, a local weighted linear regression algorithm, a polynomial regression algorithm, a GBDT Gradient Boosting Decision Tree algorithm (Gradient Boosting Decision Tree), a random forest and other algorithms.
S6: predicting the traffic data by adopting an intelligent algorithm; the embodiment adopts a time series algorithm to calculate the predicted traffic data.
S7: an intelligent algorithm is adopted to establish an IT capacity resource consumption model which is used for describing the relation between the business volume and the IT capacity resource consumption and calculating the use condition of the IT capacity of the hardware resource consumed by different business volumes running on the system. In the embodiment, a local weighted linear regression algorithm is adopted to perform modeling calculation of the IT capacity resource consumption model.
S8: and after the future service volume data are predicted and the IT capacity resource consumption model is established, calculating the predicted consumption data of the IT capacity through the future service volume data and the IT capacity resource consumption model.
The calculation index of the IT capacity predicted consumption data is as follows:
CPU utilization and memory utilization of server capacity; storage capacity usage of storage capacity; and predicting the IT capacity and setting corresponding hardware according to the predicted traffic data size and the predicted delay of the network capacity. The cluster capacity refers to the utilization rate of a CPU (central processing unit) of a server or a virtual machine in a cluster, the utilization rate of a memory of the server or the virtual machine in the cluster, and the storage utilization rate of the server or the virtual machine in the cluster.
The applicant believes that any business that runs on an information system requires consumption of hardware resources, and typically the hardware resources consumed by a business are considered to be the unit IT cost of the business. The unit transaction cost for completing the basic operation of the same service is invariable, and the unit hardware capacity consumed by the same service is basically constant even if the same service is operated on different hardware at different time. By the constant relation, the IT capacity of different traffic can be calculated by utilizing the CPU resource consumption of a single service. Therefore, the embodiment of the invention can perform the calculation of the model for predicting the traffic data and the IT capacity resource consumption by adopting a common artificial intelligence algorithm. If the time series algorithm is adopted to calculate the predicted traffic data, the linear regression algorithm and the local weighted linear regression algorithm are adopted to model and calculate the IT capacity resource consumption model.
The formula for modeling calculation by using the local weighted linear regression algorithm in this embodiment is as follows:
Figure BDA0002722695880000061
where S 'is the predicted traffic volume, R' is the predicted IT resource consumption,
Figure BDA0002722695880000062
is a regression coefficient;
Figure BDA0002722695880000063
the regression coefficient calculation formula of (2) is as follows:
Figure BDA0002722695880000064
wherein S is historical traffic, R is historical IT resource consumption, and W is a weight matrix;
this matrix has only diagonal elements:
Figure BDA0002722695880000065
where k is a hyperparameter describing the rate at which the degree of significance decreases as the distance between the known sample and the predicted sample increases; s(i)Is the historical traffic and s' is the predicted traffic.
Where latency refers to the time it takes to make the last round trip from the network, i.e., the sum of all latencies. Latency is one of the indicators for predicting IT capacity. For example, IT is first predicted how large the transaction amount will be in the future 1 month, for example, IT is predicted that 500 transactions will be in the future 1 month, but the current system can only perform 100 transactions, and then if the system IT capacity needs to support 500 transactions, the network system needs to be expanded, and the network system needs to be reset or configured, so that the network system can have a network system that satisfies the IT capacity of 500 transactions in the future 1 month. Such as taking measures of increasing storage space, increasing servers, etc.
For another example, the utilization rate of the cluster capacity is increased, that is, the CPU utilization rate of the servers or virtual machines in the cluster is increased, the memory utilization rate of the servers or virtual machines in the cluster is increased, and the storage utilization rate of the servers or virtual machines in the cluster is increased.
Referring to fig. 2, the traffic-based IT capacity prediction system of the present embodiment includes the following modules and functions:

A service scene screening module: the user can screen out the service volume data and the time points required by meeting the scene conditions according to the predicted service scene. The business scene can be the bank transaction number of a bank counter, an internet bank or a mobile phone client, the passenger number of the transportation industry, or the patient number of the outpatient service of a hospital or an emergency; the time points can be working days, release days of financial products, gold or stock market fire explosion dates, Taobao Shuangelen network promotion dates and other time points, are traffic and transportation peaks such as national celebration, spring festival and the like, and can also be the outbreak peak period of flu in autumn and winter.
An IT capacity data acquisition module: the module collects server resource data consumed by a background IT system, storage resource data, network resource data, cluster capacity resources and other historical data.
An IT capacity scene screening module: the module screens data that remains within a stable time period between the application version, the system software version, and the IT resource configuration. The predicted result is affected by the upgrade of the application version, the system software (including operating system, middleware, database, etc.) version, or the configuration of the IT resources including the change of the hardware server model and the storage server model.
A data cleaning and noise reduction module: the module carries out cleaning of supplementing vacancy values and removing noise points on all collected traffic data and IT capacity data so as to ensure that accurate calculation can be carried out on the data when the calculation of future traffic is predicted.
A traffic prediction module: the module will use a time series algorithm to perform the calculation of the predicted future traffic data.
An IT capacity resource consumption modeling module: the module is used for establishing an IT capacity resource consumption model, describing the relation between the business volume and the IT capacity resource consumption, and calculating the use condition of the IT capacity of the hardware resource consumed by different business volumes running on the system. In the embodiment, a local weighted linear regression algorithm is adopted to perform modeling calculation of the IT capacity resource consumption model.
An IT capacity resource consumption prediction module: the module predicts hardware resources required to be consumed by running future traffic data on a system, such as server capacity, and stores resource data, such as storage disk capacity, according to an IT capacity resource consumption model; and calculating predicted consumption data of the IT capacity according to the network resource data such as bandwidth and time delay, and consumption data of cluster capacity resources and the like, and performing corresponding hardware resource configuration according to the predicted consumption data of the IT capacity calculated by the IT capacity resource consumption module, such as configuration of hardware resources such as servers or storage disks and the like.
Example 1
Referring to fig. 1 and 2, the enterprise predicts the traffic and IT resource consumption of the next day by using the traffic and IT resource consumption of the past day, and performs the following steps:
s1, collecting the historical traffic data of the service during the commissioning, as shown in fig. 3, the traffic from 4 o 'clock to 12 o' clock in the past day. Specific values refer to table 1 below:
time of history Historical traffic/pen transactions
4:11 470
4:12 429
4:13 471
4:14 464
4:15 499
S2, screening a service scene; since the task is to evaluate future traffic, no special scenarios such as promotions etc. are involved, and therefore no screening is needed.
S3, collecting IT capacity data during test operation; the method comprises the steps of collecting data such as server resources, storage resources and network resources consumed by a background IT system.
In this embodiment, only the percentage of CPU resource usage of the mysql database is selected as an example, as shown in FIG. 4. Specific values refer to table 2 below:
Figure BDA0002722695880000081
and step S4, IT capacity scene screening. In the time period of the embodiment, the application version, the system software version and the IT resource configuration are not changed, because the IT capacity does not need to be screened;
s5, cleaning and denoising all data collected in the S2 business scene and S4 IT capacity scene screening step; so as to facilitate the following intelligent algorithm to perform accurate calculation. Since the values shown in the above tables are all present and have no significant noise, the present embodiment does not require cleaning and noise reduction.
And step S6, traffic prediction is carried out by using an ARIMA time series algorithm, and the traffic S' of the next day in the future is predicted.
The ARIMA Model is called an Autoregressive Integrated Moving Average Model (ARIMA), and is a famous Time-series prediction method proposed by bosch (Box) and Jenkins (Jenkins) in the beginning of the 70 s, so the ARIMA Model is also called a Box-Jenkins Model and a bosch-Jenkins method. Wherein ARIMA (p, d, q) is called a differential autoregressive moving average model, AR is autoregressive, and p is an autoregressive term; MA is the moving average, q is the number of terms of the moving average, and d is the number of differences made when the time series becomes stationary. The ARIMA model is a model established by converting a non-stationary time sequence into a stationary time sequence and then regressing a dependent variable only on a hysteresis value of the dependent variable and a current value and a hysteresis value of a random error term. The ARIMA model includes a moving average process (MA), an autoregressive process (AR), an autoregressive moving average process (ARMA), and an ARIMA process depending on whether the original sequence is stationary and the part involved in the regression.
Prediction algorithm process of ARIMA:
1) checking time series
Firstly, whether a time sequence is a pure random sequence (also called a white noise sequence) is identified according to an LB test (Ljung-Box test), and if the time sequence is the pure random sequence, an auto. (if the p-value of LB test is less than 0.05, it is not a purely random sequence).
② identifying the stationarity of the time sequence according to ADF Test (unit root Test). The smoothness of the p-value is judged by ADF inspection, and if the p-value is less than 0.05, the time sequence is considered to be smooth.
2) And smoothing the non-stationary time series data by d times of difference until the P value of the processed time series is less than 0.05 after the processed time series is subjected to ADF inspection.
3) After the stabilization, the prediction model is determined and the values of the correlation parameters are estimated by whether the autocorrelation function and the partial autocorrelation function are truncated or trailing, as shown in the relationship between the model and the function in table 3 below.
Table 3 is a model and function relationship table:
model (model) AR(p) MA(q) ARMA(p,q)
Autocorrelation function Tailing, exponential damping or oscillation Finite length, truncation (q order) Trailing, exponentially decaying, or oscillating of order q
Partial autocorrelation function Finite length, truncation (p order) Tailing, exponential damping or oscillation p-order tailing, exponential decay, or oscillation
If the partial autocorrelation function is truncated and the autocorrelation function is trailing, an AR model (ARIMA (p, d,0)) is established;
if the partial autocorrelation function is trailing and the autocorrelation function is truncated, establishing an MA model (ARIMA (0, d, q));
and establishing an ARIMA model (ARIMA (p, d, q)) if the partial autocorrelation function and the autocorrelation function are both trailing.
4) After the model is determined and p and q parameters are obtained through prediction, different ARIMA (p, d and q) models are synthesized according to the parameters, the AIC values of the ARIMA (p, d and q) models are compared according to an AIC rule (akachi pool information criterion), and the model with the minimum AIC value is taken as a final model.
5) And (5) checking whether the residual sequence of the final model is a pure random sequence, and if so, determining that the model is qualified. Otherwise, adjusting the number p of autoregressive terms and the number q of moving average terms until a qualified ARIMA prediction model is obtained.
6) And (3) taking the data acquired by the traffic data acquisition module as prediction sample data, predicting by using the ARIMA (p, d, q) model tested in the step 5, and generating traffic prediction data of 3 hours in the next day.
According to the ARIMA algorithm:
1) the time series was examined, and the results are shown in table 4:
ADF test results Test Statistic -4.15823
P value of t statistic p-value 0.000775
Number of delay steps #Lags Used 24
Number of observed values Number of Observations Used 1403
Critical ADF verified values at 99% confidence intervals Critical Value(1%) -3.43502
Critical ADF verified values at 95% confidence intervals Critical Value(5%) -2.8636
Critical ADF checked values at 90% confidence interval Critical Value(10%) -2.56787
The time series is considered to be smooth if the p-value is less than 0.05. From table 4 it can be seen that the p value is 0.000775, so this embodiment satisfies the condition that the ARIMA algorithm must be smooth for the time series of traffic.
2) And carrying out smoothing processing on the non-stationary time series data by d times of difference. Until the P value of the processed time series is less than 0.05 after ADF inspection. Since the time series is smooth, the difference processing is not required.
3) After the stabilization processing, judging a prediction model and estimating the value of the related parameter according to whether the autocorrelation function and the partial autocorrelation function are truncated or trailing.
First the autocorrelation graphs of the stationary time series are examined as shown in fig. 5 and the partial autocorrelation graphs are examined as shown in fig. 6. The auto-correlation and the partial phase coefficient are both found to have the characteristic of tailing, and both have obvious first-order correlation, so the parameters p and q of the model are set to be 1 and 1 respectively. Data fitting was performed using the ARIMA model below. No ARIMA (time series of traffic data, order ═ 1,0,1)) is used for fitting here. As shown in fig. 7, the solid line on the left of the time axis represents historical traffic, and the dashed line on the right represents traffic predicted by the model ARIMA at 3 hours on the next day. The predicted traffic values are shown with reference to table 5 below:
time of day in the future Predicted traffic/pen transactions
3:06 477.85
3:07 484.78
3:08 485.54
3:09 487.96
3:10 489.42
And S7, establishing an IT capacity resource consumption model by adopting a local weighted linear regression algorithm, and modeling the relation between the traffic and the IT capacity resource consumption.
For a good system, under light pressure, the resource usage increases linearly with increasing traffic, levels off after entering the heavy pressure region, but drops sharply after reaching the knee region. The nonlinear relationship cannot be well described by adopting a linear model, a straight line cannot be well fitted with all data points, and even a large error exists. In order to solve the problem of establishing a linear model in a nonlinear model, when predicting the value of a certain point, the inventor selects a point close to the point instead of all points to perform linear regression. Based on which a locally weighted regression algorithm is used.
Local Weighted Linear Regression (localization Weighted Linear Regression) is based on the idea of a non-parametric learning algorithm, so that the selection of characteristics is better, each point near a predicted point is given a certain weight, and common Linear Regression is performed on the basis of a wavelength function, so that accurate fitting of the near points can be realized, and the contribution of points far away can be ignored. Namely, the weight of the near point is large, the weight of the far point is small, k is a wavelength parameter, the speed of the weight descending along with the distance is controlled, the larger the descending is, the smaller the descending is, the more accurate the descending is, and the overfitting problem can occur.
The formula using locally weighted linear regression is as follows:
Figure BDA0002722695880000101
where S 'is the predicted traffic volume, R' is the predicted IT resource consumption,
Figure BDA0002722695880000102
are regression coefficients.
Figure BDA0002722695880000111
The regression coefficient calculation formula of (2) is as follows:
Figure BDA0002722695880000112
where S is historical traffic, R is historical IT resource consumption, and W is a weight matrix.
The weight matrix W has only diagonal elements,
Figure BDA0002722695880000113
where k is a hyperparameter describing the rate at which the degree of significance decreases as the distance of the known sample from the predicted sample increases. s(i)Is the historical traffic and s' is the predicted traffic. The core code of the locally weighted linear regression is as follows:
Figure BDA0002722695880000114
in this embodiment, the relationship between traffic and mysql CPU resource consumption is modeled. The modeled data is derived from the traffic volume at step S1 and mysql CPU resource usage at step S3 as described above, with reference to table 6 below.
Time of history Traffic/pen transactions mysql CPU resource usage/percentage
4:11 470 42.43
4:12 429 43.25
4:13 471 43
4:14 464 44.17
And respectively taking values of 0.1,10 and 100 for the hyper-parameter k, then calculating through the core code of the local weighted linear regression, and drawing the prediction result. As shown in fig. 8, 9 and 10 for the plots between the predicted and actual values for the locally weighted linear regression model for the cases where K is 0.1,10 and 100, respectively. As can be seen from the figure, when k is 0.1, the model fluctuates frequently and cannot be predicted well. When k is 100, the model becomes linear, but IT cannot describe the gradual saturation of IT resource consumption when mysql CPU exceeds 50% of the weight pressure. Only when k is 10, the relation between the traffic and the mysql CPU resource consumption can be accurately expressed. So, the required IT capacity resource consumption model is shown in fig. 9 when k is 10.
S8, predicting IT capacity consumption by using an IT capacity resource consumption model; the predicted traffic volume S' calculated in step S6 is substituted into the model of S7, and the required IT capacity can be predicted. As shown in table 7.

Example 2
In this example, 1440 pieces of data were obtained at 24 hours per 1 day, and the tables could not be laid down, and thus the following tables were expressed by using variables.
The embodiment predicts the traffic data and the IT capacity resource demand during the double eleven shopping wild season, and adopts the following steps:
and S1, collecting and counting historical service volume data of different services through a service volume data collection module. The banking business can be divided into modes of a network outlet counter, a network bank, a mobile phone app client, an Automatic Teller Machine (ATM) and the like according to the accessed channels, and the business volume data S of the 4 channels are respectively collectedbank、Snetwork、Smobile、SATMAs shown in table 8. Traffic data was collected every 1 hour interval, from 0 to 23, for a total of 24 x 4 samples per day.
And S2, screening out the service and time meeting the requirements of various scenes through a scene screening module. The feature of the traffics such as the double eleven shopping festivals is that the peak value of the transaction is highest from 0 a.m., and then gradually decreases. This special traffic variation is not present at other times. Therefore, the twenty-one situation needs to be proposed as a special scene, and historical data of the annual traffic change of the twenty-one situation, such as traffic transaction data during the twenty-one period in the last 3 years, is screened out. Since the transaction volume at 0 am is very low for most other dates than the twenty-one term. Therefore, if the screening of the traffic and the time is not performed, the calculation of the prediction algorithm performed later is influenced, so that the transaction amount of the final prediction result at 0 point in the morning is also low, and the prediction of the IT capacity traffic is unreasonable and inaccurate. IT will also result in inaccurate predictions of IT capacity, reduced utilization of IT capacity and resources, and even interruption of traffic transactions due to exhaustion of IT capacity and resources. The present embodiment selects traffic for the time period of 11 months 1 to 11 months 11 days per year as the data input.

In the time period of this embodiment, in 12 months in 2017, the hardware device is updated, the CPU of the old model is replaced with the CPU of the new model, and the utilization rate data of the CPU of the old model has no referential significance in consideration of the difference in processing capacity between the CPUs of the new and old models. The data in 2017 would then be filtered out and the following process would only process traffic and IT capacity data in 2018 and 2019.
And S5, performing cleaning for supplementing vacancy values and removing noise points on all the acquired traffic data and IT capacity data through a data cleaning and noise reduction module, and processing vacancy values and abnormal values in the acquired data to ensure that the data is effective in prediction calculation.

Through the steps, the IT system capacity management personnel of the service can clearly know the service volume of the new service in a certain day in the future and the required IT capacity, so that the preparation is made and the hardware resources are reasonably configured.
Example 3
The embodiment is that the IT system is used for dealing with infectious disease outbreak in a certain period, such as whether medical facilities of medical institutions in areas where fever patients are concentrated are fully prepared during a new crown epidemic situation, so as to ensure that the patients can be effectively treated during the whole epidemic situation. If a large number of fever patients appear in hospital outpatient service and need to shoot lung CT images to investigate new coronary pneumonia, the consumption of IT equipment resources related to CT is greatly increased, and the existing IT equipment related to CT in hospital can not meet the requirements far away. At this time, the medical administration department can predict the number of future infected persons by the calculation and prediction method according to the embodiment of the present invention based on the number of confirmed persons of pneumonia caused by new coronary pneumonia that has been confirmed in the past one week or several days, and can urgently purchase or allocate CT-related equipment of hospitals in other areas to support hospitals in epidemic situation outbreak areas by calculating and predicting the number of CT equipment required.
Example 4
The present embodiment is a location and analysis of IT capacity resource problems due to increased traffic. The increase in IT capacity may be due to increased traffic and may be caused by performance problems with IT applications or system software. The embodiment can identify the IT capacity change caused by the IT application program or system software by calculating and predicting the IT capacity change data caused by the increase of the traffic. For example, when 10 versions of an application program are produced on a certain day, the IT resource utilization rate is high because of an error of one application program. When the IT capacity algorithm prediction is carried out on the 10 application programs, if the IT resource consumption of one application program is obviously beyond the predicted value, the application program is indicated to have defects or errors. Therefore, the calculation and prediction method of the embodiment and the above embodiments can be used for quickly performing positioning analysis and emergency treatment, and solving the problem of IT capacity.
The innovation of the present invention is to predict future IT capacity from a traffic point of view, whereas the prior art point of view is to predict future IT capacity only from past IT capacity. But the increase in IT capacity may be due to increased changes in traffic and may also be due to performance degradation issues with the application system. Therefore, the invention adopts an intelligent algorithm to predict the future traffic trend, predicts the IT capacity requirement of a certain period of time in the future through a model of traffic and resource consumption by modeling the relationship between the IT capacity traffic and the resource consumption and thereby prepares sufficient resources for the IT capacity and avoids service interruption caused by the exhaustion of the IT capacity and the resources. The invention can predict the IT capacity business volume more reasonably and accurately in actual operation, thereby improving the IT capacity and the utilization rate of resources.
The above-described embodiments of the present invention are merely exemplary, and various changes may be made in these embodiments without departing from the design principle of the present invention, and these changes are also to be considered as the scope of protection of the present invention and its equivalents.
