摘要
提出一种用于监控系统的监控指标的趋势分析方法,包括两种趋势分析,分别为预测分析和周期性分析,前者通过线性回归算法和指数回归算法预测指标的未来值;后者通过三角函数回归算法计算指标的周期性参数。根据趋势分析结果和事先设定的报警阈值确定是否预先报警,绘制该指标变化的周期性曲线。该方法能够实现网络监控系统在监控指标发生违例前预先报警,自动生成指标变化周期性曲线,为监控系统增加了趋势分析功能。
A trend analysis method for monitoring metrics in monitor system is proposed, which includes forecasting analysis and periodicity analysis. The former analysis predicts the future values of monitoring metrics through the linear regression algorithm and exponential regression algorithm, while the latter analysis calculates the periodic parameters of monitoring metrics through the trigonometric function regression algorithm. The method can draw the periodic curves of monitoring metrics, and can generate pre-alarms according to the results of trend analysis and the pre-set thresholds. By using the presented method, network monitoring systems have the ability of ~eneratin~ ore-alarm~ and c.~n ;^n：^： ,
