Configuring Alarm Policy for Data Migration

Last updated: 2022-09-02 14:50:00

    Overview

    You can use CM to set alarm rules for important metrics during data migration. CM will send notifications to you as soon as a metric becomes abnormal, so you can take corresponding measures.

    This document describes how to set notification rules for metric alarms, including the trigger condition and scope of metric alarms, form of notifications, time period for notifications, and recipient group.

    Adding an alarm policy

    1. Log in to the CM console.
    2. Select Alarm Configuration > Alarm Policy on the left sidebar to enter the alarm policy configuration page.
    3. Click Create and configure a new alarm policy as detailed below:

      • If you select Instance ID, the alarm policy will be associated with the selected instance.
      • If you select Instance Group, the alarm policy will be associated with the selected instance group.
      • If you select All Objects, the alarm policy will be associated with all instances under the current account.
      Configure manually
      • Trigger Condition: You can choose to make the alarm triggered when any or all metrics meet the set condition.
        • Configuration example: The metric is "RPS read from source database", the statistical period is 1 minute, the comparison relation is "<", the threshold is "1", and the consecutive monitoring duration is "3 consecutive data points".
        • Configuration effect: The "RPS read from source database" metric is collected once every minute. If the number of rows read by DTS from the source database per second is below 1 for three consecutive times, an alarm will be triggered.
      • Alarm frequency: You can customize the frequency for repeated alarm notifications, such as once every hour, 2 hours, or day.
