Static alert directly sets a static performance value and a static availability value, sets the conditions for alert triggering, and triggers when the trigger is met or one of the conditions is met.
Since the content of some websites or other changes at any time, using static alerts will not be flexible enough. The biggest difference between dynamic alerts is that they can change dynamically based on an alert. The system administrator can specify a calculation period, during which the alert can change flexibly.
Anomaly detection algorithm based on time series prediction
Statistical methods based on data models are the most widespread anomaly detection technology. Its basic principle is to perform statistical modeling on the training data set (usually normal samples). If a data sample does not conform to the random model obtained by training, it will be identified as an abnormal sample. The fact that the data sample does not conform to the random model means that the sample is unlikely to be generated by the model. It is generally determined through statistical testing, based on the following assumption: normal data samples occur in the high probability area of the statistical random model, while abnormal data samples occur in the low probability area of the model. That is to say, we can get the probability that an unknown data sample is generated by a known model based on the test statistic. If the probability is less than a predetermined standard, the sample is considered an anomaly.
Intelligent alert algorithm based on machine learning
Through the anomaly detection algorithm based on time series prediction, we can allow the alert system to complete fault detection and alert work automatically and relatively accurately, thereby greatly reducing the arduous manual setting of alert thresholds for various performance indicators and manual management tasks, and achieving the purpose of automatic and intelligent fault detection.
Alert overview: including alert name, alert type, task name, Task Type, alert status, alert duration, and grouping method.
Alert timeline: represents the process of alert triggering, displayed in order from left to right, including normal alerts (orange), severe alerts (red), and alert cancellations (green). After selecting a point in the timeline, the scatter chart data below will be refreshed to display the monitoring data during that time period.
Alert detailed data: Displays the monitoring data in the current alert period with scattered point data.
