A commerce startup wants its dashboards to show counts of checkouts completed and accounts created, not just server response times. Which Application Insights capability should the developers use?
Show answer and explanation
Answer: B
Application Insights accepts custom telemetry through its SDK. Custom events represent discrete business actions such as a completed checkout, and custom metrics track numeric values over time. Automatic collectors cover requests, dependencies, exceptions, and page views, which describe technical behavior rather than business outcomes. Those built-in categories therefore cannot replace explicitly instrumented business signals.
Why the other options are wrong
- A. Dependency telemetry records calls to external systems such as databases. It reveals technical latency and failures, not how many checkouts a business completed.
- C. Browser page view timing measures how long pages take to load for users. It does not count business transactions or new account registrations.
- D. Exception telemetry captures errors thrown by the application. Failures are useful for debugging but do not report successful business activity.
