Application Insights for apps in Azure - Step-by-Step Execution

Process Flow - Application Insights for apps

App sends telemetry data

↓

Application Insights collects data

↓

Data is processed and stored

↓

User views metrics and logs in portal

↓

Alerts and diagnostics configured

↓

App performance monitored continuously

Application Insights collects data from your app, processes it, and shows you useful info to monitor and improve your app.

Execution Sample

Azure

1. Enable Application Insights in app
2. App sends telemetry (requests, exceptions)
3. Data stored in Azure Monitor
4. View data in Azure Portal
5. Set alerts for issues

This flow shows how an app sends data to Application Insights and how you monitor it.

Process Table

Step	Action	Data Sent/Processed	Result/Output
1	App starts with AI enabled	No data yet	App ready to send telemetry
2	App sends request telemetry	Request details (URL, duration)	Data received by AI
3	App sends exception telemetry	Exception details (error message)	Data received by AI
4	AI processes data	Aggregates requests and exceptions	Metrics updated
5	User views portal	Metrics and logs displayed	Insight into app health
6	User sets alert	Alert rule created	Notification on issues
7	App continues sending data	Continuous telemetry	Ongoing monitoring

💡 Monitoring continues as long as app runs and AI is enabled

Status Tracker

Variable	Start	After Step 2	After Step 3	After Step 4	After Step 5	Final
Telemetry Data	None	Request data sent	Request + Exception data sent	Data aggregated	Data displayed	Continuous data flow
Alerts	None	None	None	None	Alert rule created	Alerts active

Key Moments - 3 Insights

Why does the app send different types of telemetry data?

Because Application Insights collects various info like requests and exceptions separately to give a full picture, as shown in steps 2 and 3 of the execution_table.

How does the user see the app's health status?

The user views processed and aggregated data in the Azure Portal at step 5, which shows metrics and logs for easy understanding.

What happens if the app stops sending telemetry?

Monitoring pauses because Application Insights relies on continuous data from the app, as indicated by the continuous data flow in the final variable_tracker state.

Visual Quiz - 3 Questions

Look at the execution_table, what data is sent at step 3?

A User alert settings

B Request details like URL and duration

C Exception details like error message

D Aggregated metrics

💡 Hint

Check the 'Data Sent/Processed' column at step 3 in execution_table

At which step does the user create an alert?

A Step 2

B Step 6

C Step 5

D Step 4

💡 Hint

Look at the 'Action' column for alert creation in execution_table

If the app stops sending telemetry after step 3, what happens to monitoring?

A Monitoring pauses due to no data

B Data aggregation increases

C Monitoring continues normally

D Alerts are automatically deleted

💡 Hint

Refer to the 'exit_note' and variable_tracker final state about continuous data flow

Concept Snapshot

Application Insights collects telemetry from your app like requests and errors.
It processes and stores data in Azure Monitor.
You view metrics and logs in Azure Portal.
Set alerts to get notified on issues.
Continuous data helps monitor app health.

Full Transcript

Application Insights is a tool that helps you watch your app's health. Your app sends information like requests and errors to Application Insights. This data is stored and processed in Azure Monitor. You can then see this information in the Azure Portal as charts and logs. You can also set alerts to get notified if something goes wrong. The app keeps sending data so you always know how it is doing.
