Comprehensive Guide to RabbitMQ Monitoring


RabbitMQ is an open-source message broker software that originally implemented the Advanced Message Queuing Protocol (AMQP). It's widely used for handling asynchronous messaging with features for reliable messaging, routing, transactions, and more. Efficient monitoring of RabbitMQ is crucial for ensuring the robustness and performance of applications that rely on it.

Monitoring RabbitMQ involves tracking various metrics and logs to understand the state of message queues, message processing, network IO, and resource utilization. Effective monitoring helps in identifying bottlenecks, understanding message throughput, and maintaining optimal performance.

Use Case: E-commerce Order Processing System

In this guide, we'll focus on monitoring a RabbitMQ instance used in an e-commerce order processing system. RabbitMQ here is responsible for handling messages related to new orders, order confirmations, inventory updates, and shipping notifications.

Step-by-Step Guide with Code Samples


  • RabbitMQ Server (version 3.8 or later)
  • Python 3.6+
  • Pika (Python AMQP library)
  • Prometheus (for metric collection)
  • Grafana (for visualization)

Step 1: Basic Setup

Ensure RabbitMQ server is installed and running. You can download and install it from the RabbitMQ official website.

Step 2: Enabling RabbitMQ Management Plugin

The RabbitMQ management plugin provides an HTTP-based API for monitoring and managing RabbitMQ nodes and clusters.

rabbitmq-plugins enable rabbitmq_management

Step 3: Setting Up Prometheus

  1. Install Prometheus: Follow the instructions on the Prometheus website.
  2. Configure Prometheus to Scrape RabbitMQ Metrics: Edit the Prometheus configuration file (prometheus.yml) to add RabbitMQ as a target.
- job_name: 'rabbitmq'
- targets: ['localhost:15672']
metrics_path: '/api/metrics'
scheme: http
username: 'guest'
password: 'guest'

Step 4: Installing and Setting Up Grafana

  1. Install Grafana: Follow the installation guide on the Grafana website.
  2. Add Prometheus as a Data Source in Grafana:
  • Open the Grafana dashboard.
  • Go to Configuration > Data Sources.
  • Add Prometheus as a data source with the URL where Prometheus is running.

Step 5: Creating a Dashboard for RabbitMQ Metrics

  1. In Grafana, create a new dashboard.

  2. Add panels to visualize key RabbitMQ metrics such as:

  • Queue Length
  • Message Rates (Publish, Deliver)
  • Node Memory and Disk Usage
  • File Descriptors Usage

You can use Grafana's query builder to fetch and display data from Prometheus.

Step 6: Writing a Python Script for Message Publishing and Consuming

import pika
import time

# Establish a connection with RabbitMQ server
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel =

# Declare a queue

# Publish a message
body='Order: 12345')

print("Sent 'Order: 12345'")

# Consuming messages from the queue
def callback(ch, method, properties, body):
print(f"Received {body}")
# Simulate work

channel.basic_consume(queue='order_queue', on_message_callback=callback, auto_ack=False)

print('Waiting for messages. To exit press CTRL+C')

Step 7: Monitoring and Analyzing the Metrics

  • Use Grafana dashboards to monitor real-time metrics.
  • Look for unusual patterns or spikes in the queue length, memory usage, and message rates.
  • Set up alerts in Grafana for threshold breaches (e.g., high memory usage, long queue lengths).


Monitoring RabbitMQ is essential for maintaining the health and performance of applications that rely on message brokering. By integrating RabbitMQ with Prometheus and Grafana, you can effectively monitor key metrics and visualize system performance in real-time.

This setup is a starting point, and you can customize it further based on the specific requirements and scale of your RabbitMQ deployment.
