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 RabbitMQ metrics and alarms.

Namespace

SYS.DMS

Instance Metrics

**Table 1** Instance metrics

publish	Publish	Rate at which messages are created in the RabbitMQ instance Unit: Count/s	0–25,000	RabbitMQ instance	1 minute
deliver	Deliver (manual ack)	Rate at which messages are retrieved (and manually acknowledged) in a RabbitMQ instance Unit: Count/s	0–25,000	RabbitMQ instance	1 minute
