Memory and disk alarms in RabbitMQ - Mini Project: Build & Apply

Memory and Disk Alarms in RabbitMQ

📖 Scenario: You are managing a RabbitMQ server that handles messages for a small online store. To keep the server healthy, you want to set up alarms that notify you when memory or disk space usage is too high.

🎯 Goal: Learn how to configure memory and disk alarms in RabbitMQ to prevent server overload and ensure smooth message processing.

📋 What You'll Learn

Create a RabbitMQ configuration dictionary with default settings

Add memory alarm threshold configuration

Add disk alarm threshold configuration

Print the final configuration dictionary

💡 Why This Matters

🌍 Real World

Setting memory and disk alarms helps prevent RabbitMQ servers from crashing due to resource exhaustion, keeping message processing reliable.

💼 Career

DevOps engineers often configure such alarms to maintain system stability and avoid downtime in production environments.

1

Create the initial RabbitMQ configuration dictionary

Create a dictionary called rabbitmq_config with a key default_user set to "guest" and a key default_pass set to "guest".

RabbitMQ

# Create the rabbitmq_config dictionary with default_user and default_pass
# Your code here

Need a hint?

Use curly braces {} to create a dictionary and add the keys with their exact string values.

2

Add memory alarm threshold configuration

Add a key memory_alarm to rabbitmq_config with the value "40MB" to set the memory alarm threshold.

RabbitMQ

rabbitmq_config = {
    "default_user": "guest",
    "default_pass": "guest"
}
# Add memory_alarm key with value "40MB" to rabbitmq_config
# Your code here

Need a hint?

Add the new key and value inside the dictionary with a comma after the previous entry.

3

Add disk alarm threshold configuration

Add a key disk_alarm to rabbitmq_config with the value "1GB" to set the disk alarm threshold.

RabbitMQ

rabbitmq_config = {
    "default_user": "guest",
    "default_pass": "guest",
    "memory_alarm": "40MB"
}
# Add disk_alarm key with value "1GB" to rabbitmq_config
# Your code here

Need a hint?

Remember to add a comma after the previous key-value pair before adding the new one.

4

Print the final RabbitMQ configuration

Write a print statement to display the rabbitmq_config dictionary.

RabbitMQ

rabbitmq_config = {
    "default_user": "guest",
    "default_pass": "guest",
    "memory_alarm": "40MB",
    "disk_alarm": "1GB"
}
# Print the rabbitmq_config dictionary
# Your code here

Need a hint?

Use print(rabbitmq_config) to show the dictionary on the screen.
