Use CloudMonitor to obtain monitoring data for instances, vhosts, queues, and exchanges - ApsaraMQ for RabbitMQ

After you create an ApsaraMQ for RabbitMQ instance, CloudMonitor automatically starts monitoring it. You can view monitoring data for instances, vhosts, queues, and exchanges to analyze instance usage. You can also set alert rules for metrics to receive alert messages when data is abnormal and handle threats promptly.

Prerequisites

If you log on as a RAM user, you must grant the `AliyunCloudMonitorReadOnlyAccess` permission to the RAM user in the Resource Access Management (RAM) console. For more information, see Step 2: Grant permissions to a RAM user.

The following code describes the policy that is used to query metrics in CloudMonitor:

{
    "Version": "1",
    "Statement": [
        {
            "Action": "cms:QueryMetric*",
            "Resource": "*",
            "Effect": "Allow"
        }
    ]
}

Billing

You are not charged for using the CloudMonitor feature with ApsaraMQ for RabbitMQ.

Metrics

The new version of ApsaraMQ for RabbitMQ supports the following metrics:

Group	Metric	Unit	Namespace	MetricName	Dimensions	Statistics
	Average inbound message rate of an instance (per minute) Note Instance inbound message rate = Total inbound messages in 1 minute / 60	items per second	acs_amqp	InstanceTPSIn	userId, regionId, instanceId	Value
	Average outbound message rate of an instance (per minute) Note Instance outbound message rate = Total outbound messages in 1 minute / 60	items/s	acs_amqp	InstanceTPSOut	userId, regionId, instanceId	Value
	Peak API request rate of an instance (max value per minute) Note How the value is obtained: The maximum value of 60 samples taken once per second over a 1-minute period.	requests/s	acs_amqp	InstanceMaxTpsInMiunte	userId, regionId, instanceId	Value
	Number of consumers	Unit	acs_amqp	InstanceConsumers	userId, regionId, instanceId	Value
	Number of connections	Count	acs_amqp	InstanceConnections	userId, regionId, instanceId	Value
	Number of channels	item	acs_amqp	InstanceChannelsNew	userId, regionId, instanceId	Value
Vhost	Inbound messages per second	items per second	acs_amqp	VHostTPSIn	userId, regionId, instanceId, vhostName	Value
	Outbound messages per second	items per second	acs_amqp	VHostTPSOut	userId, regionId, instanceId, vhostName	Value
	Number of consumers	Unit	acs_amqp	InstanceVhostConsumers	userId, regionId, instanceId, vhostName	Value
	Number of connections	Count	acs_amqp	VhostConnections	userId, regionId, instanceId, vhostName	Value
	Number of channels	Item	acs_amqp	VhostChannels	userId, regionId, instanceId, vhostName	Value
Queue	Inbound messages per second	messages/s	acs_amqp	QueueTPSIn	userId, regionId, instanceId, vhostName, queueName	Value
	Outbound messages per second	items per second	acs_amqp	QueueTPSOut	userId, regionId, instanceId, vhostName, queueName	Value
	Number of consumers	Unit	acs_amqp	InstanceVhostQueueConsumers	userId, regionId, instanceId, vhostName, queueName	Value
	Message accumulation Note The number of accumulated messages in a queue is calculated as follows: If no message TTL is set for the queue, the message accumulation is the number of unconsumed messages in the queue. If a message TTL is set for the queue, messages enter a timer that is similar to a timing wheel. The message accumulation is the number of messages in this timer and decreases as messages are consumed. If the message TTL is set for the queue but does not take effect, no messages enter the timer, and the accumulation is displayed as 0. This can happen if the TTL exceeds the maximum delay time for delayed messages, or if the TTL is set on a dead-letter queue. For information about the maximum delay time for delayed messages, see Limits. The message accumulation shown on the Queue page and the Dashboard is calculated in the same way.	Unit	acs_amqp	InstanceVhostQueueMessageAccum	userId, regionId, instanceId, vhostName, queueName	Maximum
Exchange	Inbound messages per second	items per second	acs_amqp	ExchangeTPSIn	userId, regionId, instanceId, vhostName, exchangeName	Value
Exchange	Outbound messages per second	messages/s	acs_amqp	ExchangeTPSOut	userId, regionId, instanceId, vhostName, exchangeName	Value

You can call the DescribeMetricMetaList operation to obtain information about the preceding ApsaraMQ for RabbitMQ metrics.

View monitoring data

Log on to the ApsaraMQ for RabbitMQ console. In the left-side navigation pane, click Instances.
In the top navigation bar of the Instances page, select the region where the instance that you want to manage resides. Then, in the instance list, click the name of the instance that you want to manage.
In the navigation pane on the left, click Monitoring and Alerting.
On the Monitoring and Alerting page, select a resource in the Group section and set a time range.
The following figure shows an example of monitoring data for a resource on the Monitoring and Alerting page.

Create an alert rule

Log on to the ApsaraMQ for RabbitMQ console. In the left-side navigation pane, click Instances.
In the top navigation bar of the Instances page, select the region where the instance that you want to manage resides. Then, in the instance list, click the name of the instance that you want to manage.
In the navigation pane on the left, click Monitoring and Alerting.
In the upper-right corner of the Monitoring and Alerting page, move the pointer over the icon and click Set Alert Rule.
You are redirected to the Alert Rules page of CloudMonitor.
On the Alert Rules page, click Create Alert Rule. In the Create Alert Rule panel, configure the parameters for the alert rule. For more information, see Alert service.
