Technical Field
The invention relates to the field of intelligent operation and maintenance, in particular to an operation and maintenance system load prediction method based on active detection.
Background
In an operation and maintenance system, workload prediction is very important in relation to the management of later-stage resources. The workload refers to the intensity of tasks that the application service needs to undertake, and mainly refers to how much resource needs to be used to ensure normal operation of the program. The service providing on demand is the core purpose of cloud computing, and in order to provide required computing service capacity for container service efficiently and timely, a system should predict future load workload by identifying a resource usage pattern of a program and adjust the cloud computing capacity owned by a container in advance. Therefore, effective management of the container platform on the memory resources is enhanced through effective and accurate load prediction, service performance can be prevented from being reduced, waste of idle memory resources can be reduced, and profits of enterprises can be further improved.
Load forecasting mainly has the following requirements:
1) Adaptability: the predictive model should be able to adapt to load changes of the application and learn the application dynamic behavior to reduce prediction errors.
2) History data: an effective predictive model should accurately estimate future likely behavior with reference to all effective parameters regarding workload behavior, taking into account correlations between resource patterns discovered from historical sample data.
3) Complexity: in order to predict the load timely and efficiently without affecting the normal operation of the program, the time and space complexity of the prediction model should be well controlled and should not be too complex.
4) Data granularity: the initial stage in designing a predictive model is to determine which resources should be monitored. The length of the sampling interval should then be defined, since coarse-grained long-term sampling would cause the model to lose system dynamics, while the fine-grained of short-term sampling would increase the cost of data collection and processing.
In a resource management system, many allocation schemes can directly allocate resources according to prediction, and when the fluctuation of the resources is large sometimes, the resources are released for a while and recovered, which greatly affects the stability of the system.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides an operation and maintenance system load prediction method based on active detection.
The object of the present invention is achieved by the following technical means. An operation and maintenance system load prediction method based on active detection comprises the following specific steps:

(2) Predicting the resource demand of the next time period through a resource prediction module, and setting the current resource as Z0 and the predicted resource demand as Z1;
(3) Judging through a resource comparison module, judging whether Z1 is larger than Z0, if so, turning to the step (4), and otherwise, turning to the step (5);
(4) The resource allocation module allocates resources of the next stage according to the predicted resource demand Z1, modifies the allocation recording module, and adds a judgment mark A in the original recording list, wherein the judgment mark A indicates that the resources are increased or unchanged;
(5) Calling an active detection module, calling an allocation judgment module by the active detection module, traversing a record list in the allocation record module by the allocation judgment module, constructing a judgment condition according to a judgment mark A and a judgment mark B, if the judgment condition is met, not reallocating resources, and otherwise, turning to the step (6);
(6) And the resource allocation module allocates the next-stage resource according to the predicted resource demand Z1, modifies the allocation recording module, and adds a judgment mark B in the original recording list, wherein the judgment mark B indicates that the resource is reduced.
Furthermore, the resources comprise a hard disk or a CPU, and when the resources comprise multiple types, each resource is analyzed and predicted respectively.
Further, in the step (4), the method for modifying the allocation record module includes:
assume the original list of records is: d1 D2, d3, … … dm, the modified record list is: d1 D2, d3, … … dm,1; wherein dm represents the record of the m-th resource allocation, the value of which can only be 0 or 1,0 represents that the resource is reduced, and 1 represents that the resource is increased or unchanged.
Further, in the step (5), the allocation determining module traverses the record list in the allocation record module, and if the number of 1's after the first 0's in the record list is greater than the number of 0's after the first 0's, the resource is not reallocated.
Further, in the step (6), the method for modifying the allocation record module includes:
assume the original list of records is: d1 D2, d3, … … dm, the modified record list is: d1 D2, d3, … … dm,0; wherein dm represents the record of the m-th resource allocation, the value of which can only be 0 or 1,0 represents that the resource is reduced, and 1 represents that the resource is increased or unchanged.
The beneficial effects of the invention are as follows: the invention solves the problem that the load prediction method in the prior art is lack of initiative, and the load prediction method in the prior art only judges whether resources are enough according to the existing running condition, but does not have the link of active detection. The invention provides innovation aiming at the active detection method, and ensures that the resource allocation does not fluctuate too much in the operation process and is allocated for a moment and recovered; and analyzing when the resource demand is reduced, and if the resources are often required to be improved in a short period after the resources are reduced, temporarily not recovering the resources, and keeping the system stable.
