As shown in fig. 2, in order to solve the above technical problem of unable to adjust the pressure, the method comprises the following steps:
step S201, acquiring a load parameter at the current moment and a pressure parameter at the current moment;
optionally, the load parameter is a CPU utilization C or a memory utilization M of the device to be tested. In the present disclosure, a collection agent is preset in a device to be tested, and the collection agent is used for collecting a load condition of the device to be tested, that is, the CPU utilization rate and/or the memory utilization rate. Typically, the collection agent obtains the load parameters C and M through system function call, and specifically, may calculate the parameter C by calculating a sum of CPU utilization rates of all processes in the device to be tested, and calculate the memory utilization rate calculation parameter M of all processes in the device to be tested. The above-mentionedThe collection time interval of the collection agent can be pre-specified by a configuration file, and the collection agent collects the parameter C and/or the parameter M according to the collection time interval. Typically, when there are n devices to be tested, each device to be tested is numbered, and the numbers are respectively: 1,2,3 … … n, the collection agent collects the load parameter by Ci,MiAnd expressing the CPU utilization rate and the memory utilization rate of the ith device to be tested. CurRiRPS value, lastR, indicating the current time of the ith machineiAnd indicating the RPS value of the ith machine at the last moment, wherein the current moment refers to the current acquisition time, and the last moment refers to the last acquisition time.
Optionally, the pressure parameter at the current time refers to the number of times per second (RPS) requested by the pressure generating device at the current time, and the RPS may be controlled to generate a corresponding pressure flow to the device to be tested.
It should be understood that the specific examples of the load parameter and the pressure parameter are only examples, and do not limit the disclosure, and practically any parameter capable of representing the load degree and the pressure flow may be applied to the disclosure, and will not be described herein again.
Step S202, responding to the condition that the load parameter at the current moment meets the preset condition, and adjusting the pressure parameter according to the adjustment strategy corresponding to the preset condition;
optionally, the step S202 includes: step S301, in response to the fact that the load parameter at the current moment is smaller than a supercharging threshold value, increasing the pressure parameter according to an adjustment strategy corresponding to the load parameter; step S302, in response to the fact that the load parameter at the current moment is greater than or equal to a pressurization threshold and smaller than a voltage stabilization threshold, judging whether the load parameter is the maximum load according to a judgment strategy corresponding to the load parameter; step S303, in response to the load parameter at the current moment being greater than or equal to the pressure stabilizing threshold, reducing the pressure parameter according to the adjustment strategy corresponding to the load parameter.
Optionally, the increasing the pressure parameter according to the adjustment strategy corresponding to the load parameter in response to the load parameter at the current time being smaller than the boost threshold includes: and in response to the load parameter at the current moment being smaller than the first threshold value, adjusting the pressure parameter to be P times of the pressure parameter at the current moment, wherein P is a positive real number. Illustratively, P is a positive real number and P ≧ 2. For example, taking the pressure parameter as the CPU utilization C, the first threshold is 0.5, P is 2, and the current time is the K-th time to acquire the load parameter, when C (K) <0.5, RPS (K +1) ═ 2 RPS (K) is adjusted, that is, if the current CPU utilization is lower than 50%, the pressure parameter is adjusted to be 2 times the pressure parameter at the current time. And then, at the next moment, continuously repeating the steps until the load parameter is not less than the first threshold value.
Optionally, the increasing the pressure parameter according to the adjustment strategy corresponding to the load parameter in response to the load parameter at the current time being smaller than the boost threshold includes: and in response to the load parameter at the current moment being greater than or equal to the first threshold and smaller than the second threshold, adjusting the pressure parameter to be the ratio of the pressure parameter at the current moment to the load parameter. Optionally, taking the pressure parameter as the CPU utilization C, the first threshold is 0.5, the second threshold is 0.75, and the current time is the kth time to obtain the load parameter, when 0.5 ≦ C (K) <0.75, RPS (K +1) ═ RPS (K)/C (K)) is adjusted, that is, if the current CPU utilization is less than 70% and greater than or equal to 50%, the adjustment coefficient changes between (1.25, 2], the larger the value of C (K), the smaller the adjustment coefficient 1/C (K), that is, the larger the current load, the less RPS is increased.
Optionally, the increasing the pressure parameter according to the adjustment strategy corresponding to the load parameter in response to the load parameter at the current time being smaller than the boost threshold includes: in response to the load parameter at the current time being greater than or equal to the second threshold and less than the increase threshold, adjusting the pressure parameter to be Q times the pressure parameter at the current time, wherein Q is a positive real number and Q < P. Illustratively, Q is a positive real number and 1 < Q ≦ a, where a is the reciprocal of the second threshold. For example, taking the pressure parameter as the CPU utilization C, the value of the second threshold is 0.75, and the value of the third threshold is 0.88, then 1 < Q ≦ 1.25, in this example, Q is 1.1, and the current time is the kth time to obtain the load parameter, and when C (K) is 0.5 ≦ C (K) <0.75, RPS (K +1) ═ 1.1 × RPS (K) is adjusted. And then, at the next moment, the steps are continuously repeated until the load parameter is not between the second threshold value and the third threshold value.
Optionally, the determining, according to a determination policy corresponding to the load parameter, whether the load parameter is the maximum load in response to that the load parameter at the current time is greater than or equal to an increase threshold and less than a voltage stabilization threshold includes: responding to the situation that the load parameter at the current moment is larger than or equal to the supercharging threshold and smaller than the voltage stabilization threshold, and judging whether the load parameter meets the preset condition for the first time; if the preset condition is met for the first time, starting a first timer; and if the number of times that the load parameter meets the preset condition before the first timer is overtime meets a second condition, determining the load parameter meeting the preset condition for the last time before the first counter is overtime as the maximum load. Illustratively, taking the pressure parameter as the CPU utilization C, the boost threshold value is 0.75, the regulated threshold value is 0.88, the current time is the kth time to obtain the load parameter, when 0.75 ≤ C (K) <0.88 and the threshold interval is entered for the first time, the current time ST is recorded, and a first timer is started, in this exemplary embodiment, the timeout time of the first timer is 3 minutes, when the timer reaches 3 minutes, the number cnt of the load parameter in the range of [0.75,0.88) and the total number ct of the load parameter obtained when the timer reaches three minutes are recorded, if cnt/ct >0.99, that is, in the counter timing period, more than 99% of the obtained load parameters are in the range of [0.75,0.88), before the timer is timed out, the last load parameter satisfying [0.75,0.88) is taken as the maximum load of the device to be tested, the pressure corresponding to the corresponding pressure parameter is the maximum pressure which can be borne by the device to be tested.
Optionally, the reducing the pressure parameter according to the adjustment strategy corresponding to the load parameter in response to the load parameter at the current time being greater than or equal to the regulated threshold includes: and in response to the load parameter at the current moment being greater than or equal to the pressure stabilizing threshold value, adjusting the pressure parameter to be 1/n times of the sum of the pressure parameter at the current moment and the pressure parameter at the previous moment, wherein n is a positive real number, and n > 1. For example, taking the pressure parameter as the CPU utilization C, the steady-state threshold value is 0.88, the load parameter is obtained at the current time K, and n is 2, when C (K) ≧ 0.92, RPS (K +1) ═ RPS (K) + RPS (K-1))/2 is adjusted. And then, at the next moment, continuously repeating the steps until the load parameter is smaller than the voltage stabilization threshold value.
It can be understood that the above-mentioned multiple optional embodiments may be combined together, that is, the multiple thresholds constitute a preset condition, and the adjustment policy corresponding to which threshold interval is executed when determining which threshold interval of the preset condition is satisfied by the load parameter at the current time. The threshold may also be adjusted according to specific needs, and will not be described herein.
And step S203, generating pressure flow according to the pressure parameter.
In this step, the pressure flow is generated according to the RPS (k +1) acquired in step S202, and if in the above-described alternative embodiment, the maximum load of the device to be tested has been obtained, RPS (k +1) ═ RPS (k) may be maintained until the end of the test process. When pressure flow is generated, the pressure can be constant through the token bucket, namely, the pressure generating device generates a request according to the maximum speed of the pressure generating device, the token is put into the token bucket according to the set RPS, the request can be sent only when the pressure generating device takes the token, the speed of sending the request is the speed of putting the token, and the speed of putting the token is equal to the RPS, so that the required pressure flow can be generated through the token bucket.

step S401, acquiring starting parameters;

Optionally, the acquiring the start parameter includes: acquiring an initial value of the pressure flow and a starting mode, wherein the starting mode refers to a mode of the pressure flow reaching the initial value.

A slow start mode value can be set, wherein the slow start mode value is the time for the transmission device to reach the initial RPS value, and if the slow start mode value is 1 minute, the transmission device will reach the initial RPS value in one minute after starting; and in the direct starting mode, the initial RPS value is directly reached after the starting of the transmitting device. Likewise, the RPS value may be implemented by entering the token bucket in step S203.
Optionally, the acquiring the start parameter includes: acquiring the partial pressure weight of each interface to be tested;
the generating of the pressure flow according to the starting parameter comprises: and distributing the pressure flow to each interface to be tested according to the partial pressure weight.
In this alternative embodiment, there are multiple test ports, and the pressure flow generated needs to be distributed among the multiple test ports. The interface to be tested is a device to be tested. And after the pressure flow is generated, dividing the pressure flow into a plurality of parts according to the partial pressure weight, and respectively distributing the parts to each interface to be tested. This allocation will be described in detail below and will not be described in detail here.
Through the embodiment, the pressure flow can be automatically adjusted according to the parameters of the load until the maximum load is obtained, so that the maximum load capacity of the system can be automatically tested.
On the other hand, the existing tool cannot perform partial pressure test on the secondary inlet, for example, in the pressure test of a payment channel, a very typical scenario is that the unionpay is used as the primary inlet, each bank is used as the secondary inlet, and the flow of the total inlet of the unionpay is reached in the pressure test process, and the flow is respectively limited by the flow of the inlets of the secondary banks. Therefore, another embodiment of the present disclosure is provided, and fig. 5 is a flowchart of an embodiment of a pressure flow distribution method provided in the embodiment of the present disclosure, where the pressure flow distribution method provided in this embodiment may be executed by a pressure flow distribution device, and the pressure flow distribution device may be implemented as software, or implemented as a combination of software and hardware, and the pressure flow distribution device may be integrated in some device in a pressure flow distribution system, such as a pressure flow distribution server or a pressure flow distribution terminal device.

optionally, the partial pressure weight is a value set before the pressure test, and specifically, the partial pressure weight of each interface to be tested may be obtained through a human-computer interface, or may be obtained through a specific configuration file. Typically, if there are n devices to be tested, the partial pressure weight of each device to be tested can be set to W1,W2,……Wn。
Step S502, generating pressure flow according to the pressure parameters;
optionally, the generating the pressure flow according to the pressure parameter includes: acquiring pressure parameters, wherein the pressure parameters comprise the request quantity per second; generating the pressure flow rate according to the requested quantity per second. The pressure parameter here may be an initial value of the pressure flow in step S301, or may be a pressure parameter adjusted according to the adjustment policy in step S202, and the manner of generating the pressure flow refers to the manner in step S203, and is not described herein again.
And S503, distributing the pressure flow to each interface to be tested according to the partial pressure weight.
Optionally, the allocating the pressure flow to each interface to be tested according to the partial pressure weight includes:
step S601, calculating the sum of the partial pressure weight values;
step S602, calculating the ratio of the partial pressure weight of the interface to be tested to the sum value;
step S603, distributing the pressure flow to the interface to be tested according to the ratio.
Specifically, in step S501, the partial pressure weight W of each interface to be tested is obtained1,W2,……WnThen, the sum of all partial pressure calculations is calculated, sum (W) W1+W2+……Wn(ii) a In step S602, a ratio of the partial pressure weight of each interface to be tested to the sum, i.e. Wi[ SUM (W) ]wherein WiRepresenting the weight value of the ith interface to be tested; in step S603, if the pressure parameter at the current time is set to RPS (k), RPSi＝RPS(K)*Wi(ii)/SUM (W), wherein RPSiAnd the pressure flow distributed by the ith interface to be tested is shown.
