Error Handling, Monitoring, and Observability
In Chapter 4, we introduced how to use logging in ASP.NET Core web API applications. Logging is a critical part of application development that helps developers understand what’s happening in their applications. However, logging is not enough – we need more tools to monitor and observe how our application is running. In this chapter, we will explore the following topics:
- Error handling
- Health checks
- Monitoring and observability
After reading this chapter, you will be able to understand how to monitor ASP.NET Core web API applications. You will have gained knowledge of observability and OpenTelemetry, as well as how to use some tools, such as Prometheus and Grafana, to monitor applications.
