Intelligent baseline

Prerequisites

• Your device is connected to IoT Platform. For more information, see Create a product.

• The device diagnostics feature is enabled. For more information, see Enable and disable device diagnostics.

Background information

Before you use the intelligent baseline feature, understand the following concepts:

• Intelligent baseline training algorithm: Runs daily in the early morning to generate a prediction model for each intelligent baseline.

• Intelligent baseline prediction algorithm: Runs every minute to produce a metric value based on the current metric data and the prediction model.

  

Create intelligent baseline

1. Log on to the IoT Platform console.

2. In the upper-left corner of the console, select the region where your target Enterprise Edition instance is located. Then, on the Instance Overview page, find the corresponding Enterprise Edition instance and single click its name.

3. In the left-side navigation pane, select Monitoring & Operations >Device Diagnostics, and then single click Intelligent Baseline.

4. On the Intelligent Baseline page, single click Create Intelligent Baseline. In the dialog box that appears, configure the parameters and then single click OK.

   Parameter	Description
   Intelligent Baseline Name	Assign a name to the intelligent baseline for easy identification. It supports Chinese, English letters, numbers, and underscores (_), up to 32 characters in length. You can modify the name after creation. Once the intelligent baseline is established, it supports modifications.
   Chart	Choose the detection metric for the intelligent baseline. For available metrics, refer to Metric Description in this topic.
   Product	Select the product to be monitored by the intelligent baseline, either All Products or a specific product.
   Alert Sensitivity	The alert sensitivity level determines the frequency of alert generation. You can adjust this setting after creating the intelligent baseline. Once the intelligent baseline has been established, it supports modifications.

View intelligent baseline detection information

After the intelligent baseline is created, you can view its details in the list.

The Status column shows the daily training status of the intelligent baseline.

• Training: The intelligent baseline has been created for less than 14 days and training is not yet complete.

• Training Abnormal: The intelligent baseline has existed for at least 14 days, but training failed due to insufficient metric data or average metric values below the minimum training threshold.

  Note

  The training algorithm updates the status after each early-morning run. If the status shows Training Abnormal, check again the next day.

• Training Successful: The intelligent baseline has existed for at least 14 days, and the metric data volume and average values meet the training requirements.

  Note

  After successful training, the prediction model remains valid for 30 days. Alerts are generated normally during this period. If training fails for 30 consecutive days, the model becomes invalid.

• Single click the icon

  The metric line chart displays:

  Chart Data Item	Description
  Metric Value	Shows the real-time value of the metric.
  Intelligent Baseline	The baseline value predicted by the machine learning algorithm based on historical data.
  Anomaly	Whether the current metric value is abnormal, as determined by the prediction algorithm.

  Important

  Common reasons why intelligent baseline values may be absent from the chart:

  • The intelligent baseline has existed for less than 14 days and model training has not started.

  • The intelligent baseline has existed for at least 14 days, but training has not succeeded due to insufficient metric data or average values below the minimum threshold.

  • The intelligent baseline was successfully trained, but more than 30 days have passed since the last successful training, so the model is no longer valid.

Enable alert notification push

In the intelligent baseline list, single click the Alert Notification Push column's

Before using intelligent baseline alerts for the first time, click Alert Notification Configuration at the top of the page. In the Alert Notification Configuration panel, select the alert notification recipient and alert level, and click OK.

After configuring alert notifications, click View Alert Records in the Operations column to review and manage alerts in batch.
