Modern software development practices value quick and continuous updates, following processes that minimize the impact of software failures. As important as identifying bugs early, finding out if changes are improving business value are equally important. These practices can only work when a monitoring solution is in place. This article explores options for adding observability to .NET Core apps. They have been collected based on interactions with customers using .NET Core in different environments. We will be looking into OpenTelemetry and Application Insights SDKs to add observability to a sample distributed application.
