RabbitMQ Metrics

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 to query the metrics and alarms of RabbitMQ instances. You can also view the metrics on the Monitoring page of the RabbitMQ console.

Namespace

SYS.DMS
