How to Enable Debug-Level Logging for Blazor Components Using Serilog?

This article outlines the steps to enable debug-level logging in your Blazor Server application to monitor the internal behavior of Syncfusion Blazor components. By installing Serilog.AspNetCore package, you can capture detailed logs including lifecycle events, rendering processes, and JavaScript interop calls.

Steps to Enable Debug Logs

1. Install Required Package

Install the Serilog.AspNetCore package via NuGet Package Manager Console:

Install-Package Serilog.AspNetCore 

Alternatively, you can add the package via the NuGet UI in Visual Studio or directly in the .csproj file.

2. Configure Serilog in Program.cs

Update your Program.cs file to configure Serilog as the logging provider:

using Serilog;

Log.Logger = new LoggerConfiguration()
   .MinimumLevel.Debug() // Enable debug-level logging
   .WriteTo.Console()    // Output logs to the console
   .CreateLogger();

var builder = WebApplication.CreateBuilder(args);

// Replace the default logging provider with Serilog
builder.Host.UseSerilog(); 

3. Render Syncfusion Components

Render your Syncfusion Blazor components in your Razor pages or components as usual.

4. Compile and Run

Build and run your application. Once running, you will see detailed log output in the console, including:

• Component initialization

• Render cycle messages

• JS Interop calls

Sample Output (Example)

Benefits

• Easier Debugging: Track how and when components render and interact with JavaScript.

• Performance Monitoring: Identify delays or bottlenecks during rendering.

• Enhanced Observability: Gain visibility into the component lifecycle for better diagnostics.
