After you activate CloudMonitor, you can configure alert rules for Classic Load Balancer (CLB) instances in the CloudMonitor console, by calling API operations, or by using SDKs.
Background information
If a CLB instance or a CLB listener is deleted, the alert rules configured for the CLB instance or listener are also deleted.
Prerequisites
A CLB instance is created, a listener is added to the CLB instance, and health checks are enabled for the CLB instance. For more information, see the following topics:
The service label that is used to configure alert rules for CLB in CloudMonitor is obtained. In this example, the service label is SLB.
The namespace of CLB in CloudMonitor is obtained. In this example, the namespace is
acs_slb_dashboard. For more information about how to obtain the namespace, see DescribeProjectMeta.
Configure alert rules in the CloudMonitor console
- Log on to the CLB console.
In the top navigation bar, select the region where the CLB instance resides.
On the Instances page, find the instance that you want to manage and click the
icon in the Monitoring column. In the Monitoring Information panel, click Switch to Earlier Version. If you use the earlier version, skip this step.
In the Monitoring Data panel, click Threshold Alerting Settings.
On the Alert Rules page of the CloudMonitor console, click Create Alert Rule.
In the Create Alert Rule panel, configure an alert rule. For more information, see Create an alert rule.
Configure alert rules by calling API operations
The following figure shows the procedure for configuring alert rules by calling API operations.
Optional: Call the DescribeMetricMetaList operation to query the descriptions of time series metrics that are available in CloudMonitor or view the descriptions of the metrics in Monitoring and alerting metrics.
Call the PutContact operation to create or modify an alert contact.
Call the PutContactGroup operation to create or modify an alert contact group.
Call the PutResourceMetricRule operation to configure a threshold-triggered alert rule for a performance metric of a resource.
Call the DescribeMetricRuleList operation to query alert rules.
In this example, a TCP listener is configured for the lb-bp1rbwvouuyipbc*** instance. The following section describes how to configure rules to trigger Critical, Warn, and Info alerts when the number of unhealthy ECS instances exceeds the specified thresholds.
DescribeMetricMetaList
Call the DescribeMetricMetaList operation to query the descriptions of time series metrics that are available in CloudMonitor.
Set the request parameter Namespace to
acs_slb_dashboardand use the default values for other parameters.Sample request:
http(s)://[Endpoint]/?Action=DescribeMetricMetaList &Namespace=acs_slb_dashboard &<Common request parameters>View the time series metrics of CLB based on the returned parameters. Check whether the Qps parameter is returned in this example.

PutContact
Call the PutContact operation to create an alert contact. If an alert contact exists, you can call this operation to modify the alert contact.
Set the name and contact information of the alert contact in the request parameters.
In this example, configure the following parameters and use the default values for other parameters.
ContactName: the name of the alert contact.
