Use this package to integrate Serilog into your ASP.Net Web API and to logs to Grafana Loki.


1 - To view logs in console with color themes you need to run the project with HTTP or HTTPS Profile.

2 - This example is a very simple one straightforward to the point. You can add more settings to Serilog through appsettings.json

3 - Loki Connection String can be defined in appsettings.json or on the configure method as a lambda function <br>

Follow these steps to get it done:

1: Install Nuget Package

dotnet add package JF91.SerilogWithLoki


2: Add this line in program.cs after var builder = WebApplication.CreateBuilder(args);



3: Add this line in program.cs before var app = builder.Build();


3.2: Customize Loki Connection String:

builder.Host.ConfigureSerilog(() => "LokiConnection");

// OR

builder.Host.ConfigureSerilog(() => 
    // Your code
    return "LokiConnection";


4: Replace Logger in appsettings.json with this one:

4.1 Remove this:
"Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
4.2 Add this and feel free to customize it:
"Serilog": {
    "MinimumLevel": {
      "Default": "Debug"


5: Add this to your appsettings.json and modify it your needs:

"SerilogSettings": {
    "SerilogSinks": {
      "Console": true,
      "Loki": true
    "LokiSettings": {
      "Url": "http://localhost:3100",
      "CustomLabels": [


6 - Add this Environment Variable to your launchSettings.json:


How to use Serilog anywhere:

1: Inject ILogger in constructor:
public MyClass(ILogger<MyClass> logger)
    _logger = logger;
2: Writing Logs:
public void MyMethod()
    _logger.LogDebug("Debug Log");
    _logger.LogTrace("Trace Log");
    _logger.LogCritical("Critical Log");
    _logger.LogError("Error Log");
    _logger.LogWarning("Warning Log");
    _logger.LogInformation("Information Log");
