API monitoring and alerting in Rest API - Mini Project: Build & Apply

API Monitoring and Alerting

📖 Scenario: You work as a DevOps engineer responsible for keeping an important web API running smoothly. Your team wants to monitor the API's response times and get alerts if it becomes slow.Imagine you have a simple script that checks the API response time and alerts if it is too high.

🎯 Goal: Build a simple API monitoring script that stores response times, sets a threshold for slow responses, checks the response times against the threshold, and prints alerts for slow responses.

📋 What You'll Learn

Create a list of API response times in milliseconds

Add a threshold variable for slow response time

Write a loop to find response times above the threshold

Print alerts for each slow response time

💡 Why This Matters

🌍 Real World

Monitoring API response times helps keep web services reliable and fast for users.

💼 Career

DevOps engineers often write scripts like this to automate monitoring and alerting for system health.

1

Create a list of API response times

Create a list called response_times with these exact values: 120, 250, 180, 300, 90

Rest API

# Create the list response_times with the given values
# Your code here

Need a hint?

Use square brackets to create a list and separate numbers with commas.

2

Set a threshold for slow response time

Create a variable called threshold and set it to 200 to represent the maximum acceptable response time in milliseconds.

Rest API

response_times = [120, 250, 180, 300, 90]
# Create the variable threshold and set it to 200
# Your code here

Need a hint?

Use a simple assignment statement to create the variable.

3

Find slow response times

Use a for loop with the variable time to iterate over response_times. Inside the loop, use an if statement to check if time is greater than threshold. If yes, add time to a new list called slow_responses.

Rest API

response_times = [120, 250, 180, 300, 90]
threshold = 200
slow_responses = []
# Use a for loop to check each time and add slow ones to slow_responses
# Your code here

Need a hint?

Remember to create the empty list slow_responses before the loop.

4

Print alerts for slow responses

Use a for loop with the variable slow_time to iterate over slow_responses. Inside the loop, print the message: "Alert: Slow response time detected - X ms" where X is the value of slow_time.

Rest API

response_times = [120, 250, 180, 300, 90]
threshold = 200
slow_responses = []
for time in response_times:
    if time > threshold:
        slow_responses.append(time)
# Print alert messages for each slow response time
# Your code here

Need a hint?

Use an f-string inside the print statement to include the variable value.
