Prometheus and Grafana integration in RabbitMQ - Step-by-Step Execution

Process Flow - Prometheus and Grafana integration

Start RabbitMQ

↓

Enable Prometheus Plugin

↓

Prometheus Scrapes Metrics

↓

Store Metrics in Prometheus DB

↓

Grafana Queries Prometheus

↓

Visualize Metrics on Grafana Dashboard

This flow shows how RabbitMQ exposes metrics, Prometheus collects them, and Grafana visualizes the data.

Execution Sample

RabbitMQ

rabbitmq-plugins enable rabbitmq_prometheus

# Prometheus config snippet
scrape_configs:
  - job_name: 'rabbitmq'
    static_configs:
      - targets: ['localhost:15692']

# Grafana datasource setup points to Prometheus URL

This code enables Prometheus metrics in RabbitMQ, configures Prometheus to scrape those metrics, and sets Grafana to use Prometheus as a data source.

Process Table

Step	Action	Command/Config	Result/Output
1	Enable Prometheus plugin in RabbitMQ	rabbitmq-plugins enable rabbitmq_prometheus	Plugin enabled, metrics endpoint available at localhost:15692/metrics
2	Configure Prometheus to scrape RabbitMQ metrics	scrape_configs: - job_name: 'rabbitmq' static_configs: - targets: ['localhost:15692']	Prometheus scrape job for RabbitMQ configured
3	Start Prometheus server	prometheus --config.file=prometheus.yml	Prometheus collects and stores RabbitMQ metrics
4	Add Prometheus as data source in Grafana	Grafana UI: Add data source -> Prometheus URL	Grafana connects to Prometheus successfully
5	Create Grafana dashboard with RabbitMQ metrics	Use PromQL queries like rabbitmq_queue_messages	Dashboard shows live RabbitMQ metrics graphs
6	Exit	N/A	Integration complete, metrics visible in Grafana

💡 All components running and connected, metrics flow from RabbitMQ to Grafana

Key Moments - 3 Insights

Why do we need to enable the Prometheus plugin in RabbitMQ?

Without enabling the plugin (Step 1 in execution_table), RabbitMQ does not expose metrics in a format Prometheus can scrape.

What happens if Prometheus is not configured to scrape the RabbitMQ metrics endpoint?

If Prometheus is not configured (Step 2), it will not collect any RabbitMQ metrics, so Grafana will have no data to display.

How does Grafana get the RabbitMQ metrics data?

Grafana queries Prometheus (Step 4 and 5), which stores the metrics scraped from RabbitMQ, to visualize the data.

Visual Quiz - 3 Questions

Look at the execution table, at which step does Prometheus start collecting RabbitMQ metrics?

A Step 1

B Step 2

C Step 3

D Step 4

💡 Hint

Check the 'Result/Output' column for when Prometheus collects and stores metrics.

According to the variable tracker, what is the state of Grafana after Step 3?

A Prometheus data source added

B No data source

C Dashboard created

D Metrics exposed

💡 Hint

Look at the Grafana row under 'After Step 3' in variable_tracker.

If the RabbitMQ Prometheus plugin is not enabled, what will be the impact on the integration?

A No metrics endpoint available for Prometheus to scrape

B Grafana will show metrics without Prometheus

C Prometheus will scrape metrics normally

D RabbitMQ will send metrics directly to Grafana

💡 Hint

Refer to Step 1 in execution_table and the key moments about enabling the plugin.

Full Transcript

This visual execution shows how to integrate Prometheus and Grafana with RabbitMQ. First, enable the Prometheus plugin in RabbitMQ to expose metrics. Then configure Prometheus to scrape these metrics from the RabbitMQ endpoint. Start Prometheus to collect and store the data. Next, add Prometheus as a data source in Grafana. Finally, create dashboards in Grafana to visualize the live RabbitMQ metrics. The execution table traces each step with commands and results. The variable tracker shows the state changes of RabbitMQ, Prometheus, and Grafana components. Key moments clarify common confusions about enabling the plugin and data flow. The quiz tests understanding of when metrics collection starts, Grafana state, and the importance of the plugin. This integration enables monitoring RabbitMQ performance visually and in real time.
