Key metrics to monitor in RabbitMQ - Mini Project: Build & Apply

Key Metrics to Monitor in RabbitMQ

📖 Scenario: You are managing a RabbitMQ server that handles messages for an online store. To keep the system healthy and fast, you need to watch important numbers called metrics.These metrics help you know if messages are moving well, if queues are too long, or if the server is busy.

🎯 Goal: Learn how to identify and check key RabbitMQ metrics using commands.You will create a list of important metrics, set a threshold for alerts, filter metrics above the threshold, and display the results.

📋 What You'll Learn

Create a list of key RabbitMQ metrics with exact names

Add a threshold value to filter metrics

Use a loop to select metrics with values above the threshold

Print the filtered metrics and their values

💡 Why This Matters

🌍 Real World

Monitoring RabbitMQ metrics helps keep message queues healthy and prevents delays or crashes in applications.

💼 Career

DevOps engineers and system administrators use these metrics daily to maintain reliable messaging systems.

1

Create a dictionary of RabbitMQ metrics

Create a dictionary called metrics with these exact entries: 'messages_ready': 120, 'messages_unacknowledged': 30, 'consumers': 15, 'queue_length': 150, 'connections': 10

RabbitMQ

# Create the metrics dictionary with exact keys and values
# Your code here

Need a hint?

Use curly braces to create a dictionary with the exact keys and values given.

2

Add a threshold value for filtering

Add a variable called threshold and set it to 50 to use as a filter for important metrics.

RabbitMQ

metrics = {
    'messages_ready': 120,
    'messages_unacknowledged': 30,
    'consumers': 15,
    'queue_length': 150,
    'connections': 10
}
# Set the threshold value
# Your code here

Need a hint?

Just create a variable named threshold and assign it the number 50.

3

Filter metrics above the threshold

Create a dictionary called important_metrics that includes only the entries from metrics where the value is greater than threshold. Use a dictionary comprehension with for key, value in metrics.items().

RabbitMQ

metrics = {
    'messages_ready': 120,
    'messages_unacknowledged': 30,
    'consumers': 15,
    'queue_length': 150,
    'connections': 10
}
threshold = 50
# Create important_metrics dictionary with values above threshold
# Your code here

Need a hint?

Use a dictionary comprehension to pick only items where the value is greater than threshold.

4

Print the important metrics

Write a print statement to display the important_metrics dictionary.

RabbitMQ

metrics = {
    'messages_ready': 120,
    'messages_unacknowledged': 30,
    'consumers': 15,
    'queue_length': 150,
    'connections': 10
}
threshold = 50
important_metrics = {key: value for key, value in metrics.items() if value > threshold}
# Print the important_metrics dictionary
# Your code here

Need a hint?

Use print(important_metrics) to show the filtered dictionary.
