Alerts and action groups in Azure - Step-by-Step Execution

Notification or Automation

The system monitors metrics or logs, evaluates alert rules, triggers alerts if conditions are met, and executes action groups to notify or automate responses.

Execution Sample

Azure

Monitor CPU > 80%
If true, trigger alert
Alert calls action group
Action group sends email

This setup watches CPU usage, triggers an alert if it goes above 80%, and sends an email via the action group.

Process Table

Step	Metric Value	Condition (CPU > 80%)	Alert Triggered	Action Group Executed	Notification Sent
1	65%	False	No	No	No
2	82%	True	Yes	Yes	Yes
3	78%	False	No	No	No
4	85%	True	Yes	Yes	Yes
5	70%	False	No	No	No

💡 Monitoring continues; alerts trigger only when CPU > 80% condition is true.

Status Tracker

Variable	Start	After 1	After 2	After 3	After 4	After 5
CPU Usage	N/A	65%	82%	78%	85%	70%
Alert Triggered	False	False	True	False	True	False
Action Group Executed	False	False	True	False	True	False
Notification Sent	False	False	True	False	True	False

Key Moments - 3 Insights

Why doesn't the alert trigger when CPU usage is 65%?

Because the condition CPU > 80% is false at 65%, so no alert is triggered as shown in execution_table step 1.

Does the action group run if the alert condition is false?

No, the action group only runs when the alert triggers, which happens only if the condition is true, as seen in steps 2 and 4.

What happens if the CPU usage fluctuates above and below 80%?

Alerts trigger each time the condition becomes true, and action groups execute accordingly, shown in steps 2 and 4.

Visual Quiz - 3 Questions

Look at the execution_table, at which step is the alert first triggered?

A Step 2

B Step 1

C Step 3

D Step 5

💡 Hint

Check the 'Alert Triggered' column in execution_table rows.

According to variable_tracker, what is the CPU usage at step 4?

A 78%

B 70%

C 85%

D 65%

💡 Hint

Look at the 'CPU Usage' row under 'After 4' column in variable_tracker.

If the alert condition changed to CPU > 75%, how would the alert trigger at step 3 change?

A Alert would not trigger at step 3

B Alert would trigger at step 3

C Action group would execute at step 1

D Notification would be sent at step 5

💡 Hint

Compare CPU usage at step 3 with new condition in execution_table and variable_tracker.

Concept Snapshot

Alerts watch metrics or logs.
If condition is true, alert triggers.
Alert calls action group.
Action group sends notifications or runs automation.
Alerts only trigger when conditions are met.

Full Transcript

In Azure, alerts monitor metrics or logs continuously. When a condition like CPU usage above 80% is met, the alert triggers. This triggers an action group, which can send notifications like emails or run automated tasks. If the condition is not met, no alert or action occurs. This flow repeats as metrics update over time.
