    摘要:

    在應用性能管理系統中,系統未來(lái)的負載情況對運維調度有重要的指導意義。在云計算環(huán)境下,彈性伸縮計算能力為調整系統規模提供了可能,根據系統將來(lái)的負載情況可以提前做出相應的調整:可以在負載加重前擴展好集群,保證服務(wù)質(zhì)量;在負載降低之后若預測一定時(shí)間內沒(méi)有負載加重的情況,則可以及時(shí)縮減集群規模,降低企業(yè)運營(yíng)成本。在金融領(lǐng)域,ARIMA模型是常用的時(shí)序預測模型,但其應用需要人工介入分析時(shí)序的平穩性,調參過(guò)程過(guò)于復雜。近年來(lái)神經(jīng)網(wǎng)絡(luò )技術(shù)的發(fā)展帶動(dòng)了人工更智能技術(shù)的發(fā)展,本論文設計并測試了ANN、RNN、GRU、LSTM等神經(jīng)網(wǎng)絡(luò )的負載預測的效果。實(shí)驗結果表明LSTM網(wǎng)絡(luò )預測精準且表現穩定,是系統負載預測的理想模型。

    Abstract:

    In the application performance management system, the future load situation of the system has important guiding significance for the operation and maintenance scheduling. In the cloud computing environment, the elastic scaling computing capability provides the possibility to adjust the system scale. According to the future load conditions of the system, it can be adjusted in advance: You can expand the cluster before the load is increased to ensure the quality of service; after the load is reduced, If no load is expected to increase in a certain period of time, the scale of the cluster can be reduced in time and the operating cost of the enterprise can be reduced. In the financial field, the ARIMA model is a commonly used time-series prediction model, but its application requires manual intervention to analyze the temporal stability, and the adjustment process is too complicated. In recent years, the development of neural network technology has led to the development of artificially more intelligent technologies. This paper designed and tested the effect of neural network load prediction such as ANN, RNN, GRU, and LSTM. Experimental results show that the LSTM network is accurate and stable in performance and is an ideal model for system load prediction.
