Tablestore:Configure alert rules for monitoring metrics

Step 1: Create an application group and add product resources

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 values for other parameters.

      By default, Receive Event Notifications is turned on. If Receive Event Notifications is turned on, CloudMonitor automatically notifies you 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 products 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 icon to return to the Application Group page.

   On the Application Group 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.

4. In the Create Alert Template panel, configure template parameters.

   1. Enter a template name and select Tablestore for Select Alibaba Cloud Service.

   2. Click Add Rule, configure the parameters on the Metric Template tab, and click OK. The following table describes the parameters.

      You can configure parameters only on the Metric Template tab for Tablestore. You can add multiple rules based on your business requirements.

      Parameter	Description
      Rule Name	The name of the threshold-triggered alert rule.
      Metric Type	The metric type of the threshold-triggered alert rule. Valid values: Single Metric: The alert rule applies to only one metric. Multiple Metrics: The alert rule applies to multiple metrics.
      Metric Name	The name of the metric that you want to monitor. For information about how to obtain the metrics for an Alibaba Cloud service, see Appendix 1: Metrics. Note This parameter is displayed only if you set the Metric Type parameter to Single Metric.
      Threshold and Alert Level	The alert level and the corresponding threshold. The notification method for alerts of the Info level is Email + Webhook. You also need to select the number of times that the metric to be monitored reaches the alert threshold before an alert notification is sent. Valid values: 1 Consecutive Cycles, 3 Consecutive Cycles, 5 Consecutive Cycles, 10 Consecutive Cycles, 15 Consecutive Cycles, 30 Consecutive Cycles, 60 Consecutive Cycles, 70 Consecutive Cycles, 90 Consecutive Cycles, 120 Consecutive Cycles, and 180 Consecutive Cycles. Note This parameter is displayed only if you set the Metric Type parameter to Single Metric.
      Alert Level	The alert level and the corresponding alert notification methods. Valid values: Info: Email + Webhook Note This parameter is displayed only if you set the Metric Type parameter to Multiple Metrics.
      Metric Type	The method that you want to use to specify metrics and conditions. Valid values: Standard Creation: Select multiple metrics and specify conditions. Expression-based Creation: Enter an expression to specify multiple metrics and conditions. Note This parameter is displayed only if you set the Metric Type parameter to Multiple Metrics.
      Multi-metric Alert Expression	The alert rule that is created for multiple metrics. Note This parameter is displayed only if you set the Metric Type parameter to Multiple Metrics and the Metric Type parameter to Standard Creation.
      Relationship Between Metrics	The relationship between multiple metrics. Valid values: Generate alerts if all metrics meet the conditions (&&) Generate alerts if one of the conditions is met (||) Note This parameter is displayed only if you set the Metric Type parameter to Multiple Metrics and the Metric Type parameter to Standard Creation.
      Multi-metric Alert Expression	The expression that is used to specify multiple metrics and conditions. For information about how to specify multi-metric alert expressions, see Alert rule expressions. Note This parameter is displayed only if you set the Metric Type parameter to Multiple Metrics and the Metric Type parameter to Expression-based Creation.
      Select the number of times the threshold is reached before an alert is triggered	The number of consecutive triggers. If the number of times that the metric values meet the trigger conditions reaches the value of this parameter, CloudMonitor sends alert notifications. Valid values: 1 Consecutive Cycles, 3 Consecutive Cycles, 5 Consecutive Cycles, 10 Consecutive Cycles, 15 Consecutive Cycles, 30 Consecutive Cycles, 60 Consecutive Cycles, 70 Consecutive Cycles, 90 Consecutive Cycles, 120 Consecutive Cycles, and 180 Consecutive Cycles.
      Method to handle alerts when no monitoring data is found	The method that you want to use to handle alerts when no monitoring data is found. Valid values: Do not do anything Send alert notifications Treated as normal
      Tag	The tags of the alert template. The specified tags are automatically added to the alert content.
      Alert Callback	The callback URL that can be accessed over the Internet. CloudMonitor sends HTTP POST requests to push alert notifications to the specified URL. You can enter only an HTTP URL. For more information about how to configure alert callback, see Use the alert callback feature to send notifications about threshold-triggered alerts. To test the connectivity of an alert callback URL, perform the following steps: Click Test next to the callback URL. In the Webhook Test panel, you can check and troubleshoot the connectivity of the alert callback URL based on the returned status code and test result details. Note To obtain the details of the test result, configure the Test Template Type and Language parameters and click Test. Click Close.

   3. Click OK.

5. Apply the alert template to the application group.

   1. In the Create/modify alert template complete message, click Confirm.

      Note

      If you click Cancel, the alert template is created but not applied to the application group. For more information, see Apply an alert template to an application group.

   2. In the Apply Templates to Groups dialog box, select one or more application groups, configure the Mute For, Effective From, Alert Callback, and Priority parameters, and click Confirm.

   3. In the Apply Templates to Groups message, click Confirm.

      Important

      You need to wait for a while before the alert rule is created.
