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

Instance Metrics

**Table 1** Instance metrics

channels	Channels	Number of channels in the RabbitMQ instance Unit: Count	0–2047	RabbitMQ instance	1 minute
queues	Queues	Number of queues in the RabbitMQ instance Unit: Count	0–7,000	RabbitMQ instance	1 minute
consumers	Consumers	Number of consumers in the RabbitMQ instance Unit: Count	0–280,000	RabbitMQ instance	1 minute
messages_ready	Available Messages	Number of messages that can be consumed in the RabbitMQ instance Unit: Count	0–10,000,000	RabbitMQ instance	1 minute
messages_unacknowledged	Unacknowledged Messages	Total number of messages that have been consumed but not acknowledged in a RabbitMQ instance Unit: Count	0–10,000,000	RabbitMQ instance	1 minute
publish	Message Creation Rate	Rate at which messages are produced in the RabbitMQ instance Unit: Count/second	0–25,000	RabbitMQ instance	1 minute
deliver	Retrieval Rate (Manual Ack)	Rate at which messages are consumed (in the manual acknowledgment scenario) in a RabbitMQ instance Unit: Count/second	0–25,000	RabbitMQ instance	1 minute
