Practice Test 4 | Designing And Implementing Microsoft DevOps Solutions | AZ-400 | Dumps | Mock Test
Your company built a web application using ASP.NET Core. The application handles live videos and large volumes of data.
It has been reported that the application performance has deteriorated a few weeks after the project moved to production. You want to gather instrumentation data about the application quickly and decide to make use of Application insights runtime instrumentation.
You want to identify which code path takes the longest time when it is handling a web request.
Which of the following visualization tools can satisfy this requirement?
A. Comprehensive data collection
B. Metrics explorer
C. Profiler
D. Live metrics streams
Answer: C
- Option A is incorrect because Comprehensive data collection is a feature of Application insights SDK which is a part of build-time instrumentation. This provides data like user retention, unique users, and unique sessions is available in Application Insights only when you use the Application Insights SDK.
- Option B is incorrect because Metrics explorer is a tool that shows how metrics vary over time. It is a series of measured values and counts that are collected and stored over time. It provides options for visualizing metrics and simplifying chart configuration.
- Option C is correct because the profiler Shows how a set of requests, like those for a single web page, were delivered. You can use these profiles, for example, to see which page elements load slowly. Profiler helps you identify the “hot” code path that takes the longest time when it is handling a web request. Application Insights can automatically track requests for ASP.NET Core web applications.
- Option D is incorrect because Live metric streams are charts that display performance values as they vary in near-real time. You can watch the effect of test loads and diagnose issues live with live metrics steam. Compared to metrics explorer, live metrics stream display metrics data within one second.
