Monitoring Metrics for RabbitMQ AMQP-0-9-1

Introduction

This section describes metrics reported by DMS for RabbitMQ to Cloud Eye as well as their namespaces and dimensions. You can use the Cloud Eye console or APIs to query the metrics and alarms of RabbitMQ instances. You can also view the metrics on the Monitoring Details page on the DMS (for RabbitMQ) console.

Cloud Eye supports a maximum of four hierarchical dimensions that are numbered from 0 to 3. For example, if the dimension information of a monitoring metric is "rabbitmq_instance_id,rabbitmq_vhost", the dimension of "rabbitmq_instance_id" is numbered 0 and that of "rabbitmq_vhost" is numbered 1.

If a monitored object has multiple dimensions, the dimensional level of specific metrics is required when you use APIs to query the metrics.

For example, to query the total number of connections (vhost_connections) of a RabbitMQ virtual host, its dimension is "rabbitmq_instance_id,rabbitmq_vhost", indicating that rabbitmq_instance_id is numbered 0 and rabbitmq_vhost is numbered 1.

To query a single metric by calling the API, the rabbitmq_vhost dimension is used as follows:
```
dim.0=rabbitmq_instance_id,0186688d-fxxx-497bfdda6c8e&dim.1=rabbitmq_vhost,default
```
0186688d-fxxx-497bfdda6c8e and default are the dimension values of rabbitmq_instance_id and rabbitmq_vhost. For details about how to obtain them, see the guide in the Dimension table.

To batch query metrics by calling the API, the rabbitmq_vhost dimension is used as follows:

"dimensions": [ 
                 { 
                     "name": "rabbitmq_instance_id", 
                     "value": "0186688d-fxxx-497bfdda6c8e"    
                 }, 
                 { 
                     "name": "rabbitmq_vhost", 
                     "value": "default" 
                 } 
             ]

0186688d-fxxx-497bfdda6c8e and default are the dimension values of rabbitmq_instance_id and rabbitmq_vhost. For details about how to obtain them, see the guide in the Dimension table.

Dimension
