Prometheus and Grafana integration in RabbitMQ - Mini Project: Build & Apply

Prometheus and Grafana Integration with RabbitMQ Metrics

📖 Scenario: You are managing a RabbitMQ server that handles messages for your application. To keep track of its health and performance, you want to collect metrics and visualize them.Prometheus is a tool that collects metrics, and Grafana helps you create dashboards to see those metrics clearly.

🎯 Goal: Set up RabbitMQ metrics collection with Prometheus and create a simple Grafana dashboard to visualize the message rates.

📋 What You'll Learn

Enable the RabbitMQ Prometheus plugin

Configure RabbitMQ to expose metrics on port 15692

Set up Prometheus to scrape RabbitMQ metrics

Create a Grafana dashboard to display message rates

💡 Why This Matters

🌍 Real World

Monitoring RabbitMQ helps ensure your messaging system is healthy and responsive, preventing delays or failures in your application.

💼 Career

DevOps engineers often set up monitoring and alerting for message brokers like RabbitMQ to maintain system reliability.

1

Enable RabbitMQ Prometheus Plugin

Run the command rabbitmq-plugins enable rabbitmq_prometheus to enable the Prometheus plugin in RabbitMQ.

RabbitMQ

# Run the command to enable the Prometheus plugin
# Your code here

Need a hint?

This command activates the plugin that allows RabbitMQ to expose metrics for Prometheus.

2

Configure RabbitMQ Metrics Port

Add the line listeners.tcp.prometheus = 15692 to the RabbitMQ configuration file /etc/rabbitmq/rabbitmq.conf to expose metrics on port 15692.

RabbitMQ

rabbitmq-plugins enable rabbitmq_prometheus
# Add the Prometheus listener port configuration below
# Your code here

Need a hint?

This setting tells RabbitMQ to open port 15692 for Prometheus to collect metrics.

3

Configure Prometheus to Scrape RabbitMQ Metrics

Add this job to the Prometheus configuration file prometheus.yml under scrape_configs: - job_name: 'rabbitmq', static_configs:, - targets: ['localhost:15692'].

RabbitMQ

rabbitmq-plugins enable rabbitmq_prometheus
listeners.tcp.prometheus = 15692
# Add Prometheus scrape job configuration below
# Your code here

Need a hint?

This configuration tells Prometheus where to find RabbitMQ metrics.

4

Create Grafana Dashboard Panel for Message Rates

In Grafana, create a new dashboard and add a panel with the Prometheus query rate(rabbitmq_queue_messages_published_total[5m]) to show the message publish rate over the last 5 minutes.

RabbitMQ

rabbitmq-plugins enable rabbitmq_prometheus
listeners.tcp.prometheus = 15692
scrape_configs:
  - job_name: 'rabbitmq'
    static_configs:
      - targets: ['localhost:15692']
# Add Grafana panel with query below
# Your code here

Need a hint?

This query calculates how many messages are published per second over the last 5 minutes.
