Implementing Health Checks in ASP.NET Framework Applications

Published 4 years ago

Being able to monitor your ASP.NET web applications and APIs and detect any issues early on is crucial in ensuring your sites are up and running and in a healthy state. With ASP.NET Core 2.2 and later this now comes in the box (as I'll show you in later articles) but for .NET Framework apps you'll have to use to kind of custom solution. To implement simple monitoring in ASP.NET Framework apps (i.e. non-Core applications), I usually add some custom code to my projects to provide health information from an endpoint and then use external tools to monitor that endpoint. In this article I'll show you how you can implement health checks using custom code targeting the .NET Framework (although it should also work on .NET Core). In future articles I'll then show you how you can set up similar checks in an ASP.NET Core app with standard functionality and how to extend the base system using existing third-party health checks like an SMTP server monitor, to make your health checks even more powerful.

This is Part 2 in a series of 10 that show you how to build N-Layered applications using ASP.NET 4.5 and Entity Framework 5 Code First. The previous article provided some history of the architecture of the Contact Manager application and gave a broad overview of the new architecture. In this installment, things get a bit more concrete when you see how to setup a solution in Visual Studio 2012. The VS solution is going to contain three class libraries: one for the Infrastructure, one for the application’s Model and one to hold the Entity Framework (EF) Repository implementation. I’ll also add four frontend projects (an ASP.NET MVC 4, a Web Forms project, a WCF service project, and a windows command line application) which are discussed in detail in Part 6, 7, 8 and 9 of this series respectively. In the next article in this series I’ll extend the solution with four more projects for unit, integration, UI and service tests.
