After you create a Message Queue for RabbitMQ instance, CloudMonitor automatically starts to monitor the instance. You can view the metrics of instances, vhosts, queues, and exchanges to analyze the instance usage and performance. CloudMonitor also allows you to create alert rules for these metrics so that you can receive alerts and troubleshoot exceptions at the earliest opportunity.

Prerequisites

If you want to use a RAM user to manage monitoring and alerting operations, go to the RAM console and then grant the AliyunCloudMonitorReadOnlyAccess permission to the RAM user. For more information, see Step 2: Grant permissions to the RAM user.
The content of the CloudMonitor permission policy is:
{
    "Version": "1",
    "Statement": [
        {
            "Action": "cms:QueryMetric*",
            "Resource": "*",
            "Effect": "Allow"
        }
    ]
}

Metrics

The following table describes the metrics that are supported by Message Queue for RabbitMQ in the new Monitoring and Alerting page.

You can call the DescribeMetricMetaList operation to query the detailed information about the preceding metrics for your Message Queue for RabbitMQ instance.

View monitoring data

  1. Log on to the Message Queue for RabbitMQ console.
  2. In the Resource Distribution section of the Overview page, select the region where your instance is located.
  3. On the Instances page, click the name of your instance.
  4. In the left-side navigation pane, click Monitoring and Alerting.
  5. On the Monitoring and Alerting page, set the Group Name parameter to the type of resource whose metrics you want to view, set the Resource type parameter to a specific resource, and then specify a time range.
    For example, you can query the monitoring data of your instance within the last seven days. The following figure shows a sample monitoring data on the Monitoring and Alerting page. result

Create an alert rule

  1. Log on to the Message Queue for RabbitMQ console.
  2. In the Resource Distribution section of the Overview page, select the region where your instance is located.
  3. On the Instances page, click the name of your instance.
  4. In the left-side navigation pane, click Monitoring and Alerting.
  5. On the Monitoring and Alerting page, click Alert Rules in the upper-right corner. The Alert Rules page of the CloudMonitor console appears. On the Threshold Value Alert tab, click Create Alert Rule.
  6. On the Create Alert Rule page, set the parameters as required to create an alert rule. For more information, see Alerting service.
