Diagnostics

We also have a separate package that can be used for diagnosing issues in the system. These tools are provided in EventSourced.Diagnostics.Web NuGet package. By adding this package to the project and registering in the Startup class you are provided with a web pages that can be found under the _diagnostics/EventSourced/AggregateTypesList URL of your project after starting.

Note: The diagnostics pages use DotVVM framework for viewing of the data. To learn more go to: https://www.dotvvm.com/

This page provides you information regarding the state of your aggregates and the state of your registered automatic projections.
