Log analysis and troubleshooting in RabbitMQ - Mini Project: Build & Apply

Log Analysis and Troubleshooting with RabbitMQ

📖 Scenario: You are a system administrator managing a RabbitMQ server. You want to analyze the RabbitMQ logs to find error messages and troubleshoot issues quickly.

🎯 Goal: Build a simple script that reads RabbitMQ log entries, filters error messages, and displays them for troubleshooting.

📋 What You'll Learn

Create a list of sample RabbitMQ log entries

Add a filter keyword variable to identify error logs

Use a loop to filter logs containing the error keyword

Print the filtered error log entries

💡 Why This Matters

🌍 Real World

System administrators often need to analyze RabbitMQ logs to quickly find errors and fix issues in message queues.

💼 Career

This skill helps in troubleshooting and maintaining reliable message broker services in production environments.

1

Create sample RabbitMQ log entries

Create a list called rabbitmq_logs with these exact entries:
"2024-06-01 10:00:00 INFO Starting RabbitMQ server",
"2024-06-01 10:05:00 ERROR Connection refused",
"2024-06-01 10:10:00 WARNING Disk space low",
"2024-06-01 10:15:00 ERROR Queue not found",
"2024-06-01 10:20:00 INFO Server running"

RabbitMQ

# Create a list called rabbitmq_logs with the specified log entries
# Your code here

Need a hint?

Use a Python list with the exact log strings inside double quotes.

2

Add error filter keyword

Create a variable called error_keyword and set it to the string "ERROR" to identify error log entries.

RabbitMQ

rabbitmq_logs = [
    "2024-06-01 10:00:00 INFO Starting RabbitMQ server",
    "2024-06-01 10:05:00 ERROR Connection refused",
    "2024-06-01 10:10:00 WARNING Disk space low",
    "2024-06-01 10:15:00 ERROR Queue not found",
    "2024-06-01 10:20:00 INFO Server running"
]
# Create a variable error_keyword with value "ERROR"
# Your code here

Need a hint?

Use a simple string variable to hold the keyword.

3

Filter error log entries

Create a list called error_logs that contains only the entries from rabbitmq_logs which include the error_keyword. Use a for loop with variable log and an if statement.

RabbitMQ

rabbitmq_logs = [
    "2024-06-01 10:00:00 INFO Starting RabbitMQ server",
    "2024-06-01 10:05:00 ERROR Connection refused",
    "2024-06-01 10:10:00 WARNING Disk space low",
    "2024-06-01 10:15:00 ERROR Queue not found",
    "2024-06-01 10:20:00 INFO Server running"
]
error_keyword = "ERROR"
# Create a list error_logs with logs containing error_keyword
# Your code here

Need a hint?

Use a loop to check each log and add matching ones to error_logs.

4

Display filtered error logs

Use a for loop with variable error_log to print each entry in the error_logs list.

RabbitMQ

rabbitmq_logs = [
    "2024-06-01 10:00:00 INFO Starting RabbitMQ server",
    "2024-06-01 10:05:00 ERROR Connection refused",
    "2024-06-01 10:10:00 WARNING Disk space low",
    "2024-06-01 10:15:00 ERROR Queue not found",
    "2024-06-01 10:20:00 INFO Server running"
]
error_keyword = "ERROR"
error_logs = []
for log in rabbitmq_logs:
    if error_keyword in log:
        error_logs.append(log)
# Print each error log entry
# Your code here

Need a hint?

Use a loop to print each error log on its own line.
