#21 Closing the loop: instrumenting your .NET applications with OpenTelemetry

You build it, run it and own it. Knowing how your application behaves is easy in your development environment, because you have better debugging capabilities there. It gets more complicated when you run in production. Getting feedback from your application and learning its behavior is essential to close the DevOps feedback loop. In this session, you will learn what it takes to instrument your .NET application to get rich feedback in every stage of the lifecycle. We start by looking at the various ways to add logging, tracing, and metrics using the built-in .NET libraries. We will consume the telemetry data from your development environment with OpenTelemetry; no cloud required. Next, we will cover the production scenario and see how you can leverage Azure with Application Insights and Azure Monitor. By the end of your session, you will have a good understanding how to add proper instrumentation with OpenTelemetry and to put it to good use during your entire development lifecycle.
