    Tablestore:Configure alert rules for metrics

    Last Updated:Oct 21, 2024

    You can configure alert rules for metrics in the CloudMonitor console. If the conditions that are specified in an alert rule are met, CloudMonitor automatically notifies you of anomalies in the monitoring data. This way, you can troubleshoot errors at the earliest opportunity.

    Prerequisites

    An alert contact group is created. For more information, see Create an alert contact.

    Create alert rules

    Create multiple alert rules at the same time

    You can apply an alert template to an application group to which product resources are added. This way, you can create alert rules for multiple Tablestore instances in the application group at the same time.

    Step 1: Create an application group and add product resources to the application group

    The application group feature allows you to manage resources from different services and regions by group. You can create application groups based on your business requirements. You can add resources that are related to the same business to an application group. You can also manage alert rules by application group.

    1. Log on to the CloudMonitor console.

    2. Create an application group.

      1. In the left-side navigation pane, click Application Groups.

      2. On the Application Groups tab, click Create Application Group.

      3. In the Create Application Group panel, set Creation Method to Manually Create, specify the application group name and alert contact group, and retain the default settings for other parameters.

        By default, Receive Event Notifications is turned on. If Receive Event Notifications is turned on, CloudMonitor automatically notifies the alert contacts in the alert contact group when important system events occur on the instances in the application group.

      4. Click OK.

    3. Add product resources to the application group.

      1. On the Group Resources page of the application group, click Manage Services and Resources.

      2. In the Add/Modify Group Resources panel, select Tablestore for Associated Cloud Services and select a Tablestore instance.

      3. Click Ok.

        On the Group Resources page of the application group, you can view the information about the cloud service and instance that you added.

    4. On the Group Resources page of the application group, click the 返回 icon to return to the Application Groups page.

      On the Application Groups tab, you can view the application group that you create.

    Step 2: Create an alert template and apply the template to the group

    1. Log on to the CloudMonitor console.

    2. In the left-side navigation pane, choose Alerts > Alert Templates.

    3. On the Alert Templates page, click Create Alert Template.
