Monitoring your .NET services does not need to be expensive.
In this tutorial, I show you how to use Uptime Kuma to monitor .NET APIs and microservices for free.

Uptime Kuma is a self-hosted monitoring tool that lets you track websites, APIs, databases, and other services from a simple dashboard. In this tutorial, we use it with Docker and connect it to a .NET health check endpoint so you can monitor the real health of your application.

What you’ll learn:

- How to run Uptime Kuma with Docker
- How to create monitors for websites and APIs
- How to monitor a .NET health endpoint
- How to surface Postgres and Redis health through your API
- How to handle Docker networking with host.docker.internal
- How to create a status page for your services
- How to manage incidents and maintenance windows
- How to set up notifications for downtime

A practical setup for anyone running .NET apps in production, homelabs, or self-hosted environments.

A walkthrough of setting up Uptime Kuma, a self-hosted open source monitoring tool with 80k+ GitHub stars, and connecting it to a .NET application. Covers running Uptime Kuma via Docker, configuring HTTP monitors, setting up a status page, scheduling maintenance windows, and using a .NET health check endpoint to reflect the health of dependent services like PostgreSQL and Redis. Also explains how to use host.docker.internal to monitor local services from within a Docker container.
