Using Standard Health Checks and Building your Own in ASP.NET Core

Published 4 years ago

Being able to monitor your ASP.NET Core 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. In previous articles I talked about creating a custom health check solution for ASP.NET Framework applications and implementing ASP.NET Core health checks with standard functionality. In this article I'll show you how to add and configure some existing, open-source health checks to monitor an SMTP server and the web server's disk space (these are just examples; there are many more health checks available that you can plug in to your own web site). And if the standard health checks aren't sufficient, you can build your own; something you'll see how to do in the second part of this article.

Improving IntelliSense for the asp-page Tag Helper using T4 Templates

I find ASP.NET Tag Helpers super helpful. They provide powerful features and yet use clean markup. As an example, here's a tag helper that creates a link to an action method in some controller:

<a asp-controller="Contact" asp-action="Index">Get in Touch</a>

At run-time, ASP.NET then generates the correct URL for this action method and creates an href attribute on the anchor for it:

<a href="/contact">Get in Touch</a>

Being able to monitor your ASP.NET Core 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. In a previous article I talked about creating a custom health check solution for ASP.NET Framework applications. In this article I'll show you how to leverage the built-in Health Check framework along with some third-party open-source add-ons available for ASP.NET Core applications. You may want to check out the previous article to better understand health checks and why they are useful. And seeing the custom solution for the .NET Framework may have you appreciate the built-in ASP.NET Core functionality even more. And in this article I'll dive a little deeper into some existing third-party health checks that make monitoring your sites and services super easy and show you how to build your own health checks and plug them into the system.
