Alerting thresholds in HLD - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a threshold that triggers an alert when CPU usage exceeds a limit.

HLD

if cpu_usage [1] threshold:
    trigger_alert()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '<' instead of '>' causes alerts to trigger incorrectly.

The alert should trigger when CPU usage is greater than the threshold.

2fill in blank

medium

Complete the code to set a memory alert threshold at 80%.

HLD

memory_alert_threshold = [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 80 instead of 0.8 causes incorrect threshold interpretation.

80% is represented as 0.8 in decimal form for threshold setting.

3fill in blank

hard

Fix the error in the alert condition to correctly trigger when disk space is below the threshold.

HLD

if disk_space [1] threshold:
    trigger_alert()

Drag options to blanks, or click blank then click option'

B>=

C==

D<

💡 Hint

Common Mistakes

Using '>' triggers alert when disk space is sufficient, which is wrong.

The alert should trigger when disk space is less than the threshold, so use '<'.

4fill in blank

hard

Fill both blanks to create a threshold check that triggers an alert if response time is greater than 200ms and error rate is above 5%.

HLD

if response_time [1] 200 and error_rate [2] 0.05:
    trigger_alert()

Drag options to blanks, or click blank then click option'

A>

B<

D<=

Attempts:

💡 Hint

Common Mistakes

Using '<' causes alerts to trigger incorrectly when metrics are low.

Both conditions check if values exceed their thresholds, so use '>' for both.

5fill in blank

hard

Fill all three blanks to define a dictionary of alert thresholds for CPU, memory, and disk usage.

HLD

alert_thresholds = {
    'cpu': [1],
    'memory': [2],
    'disk': [3]
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up threshold values for different resources.

Common thresholds are 85% for CPU, 80% for memory, and 90% for disk usage.
