CloudWatch Logs in AWS - Mini Project: Build & Apply

Basic CloudWatch Logs Setup

📖 Scenario: You are setting up a simple logging system for a web application running on AWS. You want to collect logs from your application and store them in AWS CloudWatch Logs for monitoring and troubleshooting.

🎯 Goal: Create a CloudWatch Logs group and stream, configure a log event, and complete the setup to send logs to CloudWatch Logs.

📋 What You'll Learn

Create a CloudWatch Logs group named MyAppLogGroup

Create a CloudWatch Logs stream named MyAppLogStream inside the log group

Create a log event with a timestamp and message

Complete the configuration to put the log event into the log stream

💡 Why This Matters

🌍 Real World

CloudWatch Logs is used to collect and monitor logs from applications and infrastructure in AWS, helping teams troubleshoot and analyze system behavior.

💼 Career

Understanding how to configure CloudWatch Logs is essential for cloud engineers and developers working with AWS to maintain application health and security.

1

Create a CloudWatch Logs group

Create a variable called log_group_name and set it to the string 'MyAppLogGroup'.

AWS

# Create a variable called log_group_name and set it to 'MyAppLogGroup'
# Your code here

Need a hint?

Use a simple string assignment to create the log group name.

2

Create a CloudWatch Logs stream

Create a variable called log_stream_name and set it to the string 'MyAppLogStream'.

AWS

log_group_name = 'MyAppLogGroup'
# Create a variable called log_stream_name and set it to 'MyAppLogStream'
# Your code here

Need a hint?

Assign the log stream name as a string variable.

3

Create a log event

Create a dictionary called log_event with keys 'timestamp' and 'message'. Set 'timestamp' to 1680000000000 and 'message' to 'User login successful'.

AWS

log_group_name = 'MyAppLogGroup'
log_stream_name = 'MyAppLogStream'
# Create a dictionary called log_event with keys 'timestamp' and 'message'
# Your code here

Need a hint?

Use a dictionary with the exact keys and values as shown.

4

Complete the CloudWatch Logs configuration

Create a dictionary called cloudwatch_config with keys 'logGroupName', 'logStreamName', and 'logEvents'. Set 'logGroupName' to log_group_name, 'logStreamName' to log_stream_name, and 'logEvents' to a list containing log_event.

AWS

log_group_name = 'MyAppLogGroup'
log_stream_name = 'MyAppLogStream'
log_event = {'timestamp': 1680000000000, 'message': 'User login successful'}
# Create a dictionary called cloudwatch_config with keys 'logGroupName', 'logStreamName', and 'logEvents'
# Your code here

Need a hint?

Combine the variables into a configuration dictionary for CloudWatch Logs.
