Monitoring collects data from your app, checks for problems, alerts you if needed, and helps fix issues to keep things running smoothly.
Execution Sample
Azure
az monitor metrics list --resource /subscriptions/123/resourceGroups/myRG/providers/Microsoft.Web/sites/myApp
az monitor metrics alert create --name HighCPUAlert --condition "avg Percentage CPU > 80" --resource /subscriptions/123/resourceGroups/myRG/providers/Microsoft.Web/sites/myApp
These commands list available metrics for the app and create an alert if CPU usage goes above 80%.

Key Moments - 2 Insights
Why do we need to keep monitoring even after fixing an issue?
Because issues can happen again or new problems can appear, continuous monitoring ensures the system stays healthy as shown in steps 7 and 8.
What happens if the CPU usage never goes above 80%?
No alert is triggered and monitoring continues silently, as shown in step 8 where condition is false.
Visual Quiz - 3 Questions
Test your understanding
Look at the execution table, at which step is the alert sent to the team?
AStep 3
BStep 5
CStep 7
DStep 2
💡 Hint
Check the 'Action' column for 'Send alert' in the execution_table rows
According to the variable tracker, what is the CPU usage after the issue is fixed?
A50%
B85%
CN/A
D100%
💡 Hint
Look at 'CPU Usage (%)' value after Step 6 in variable_tracker
If the CPU usage never exceeds 80%, what happens to the alert status?
AIt turns On
BIt toggles On and Off
CIt stays Off
DIt sends multiple alerts
💡 Hint
Refer to execution_table step 8 and variable_tracker 'Alert Status' final value
Concept Snapshot
Monitoring means collecting data from your app continuously.
It checks for problems like high CPU or errors.
If a problem is found, it alerts the team.
The team fixes the issue and monitoring verifies the fix.
This cycle repeats to keep apps healthy and fast.
Full Transcript
Monitoring is essential because it helps keep applications running smoothly. It works by collecting data like CPU usage and logs while the app runs. This data is analyzed to detect problems such as high CPU usage. When a problem is found, monitoring sends alerts to the team so they can fix it quickly. After fixing, monitoring continues to verify the system is stable. This ongoing process prevents downtime and improves user experience.
