Microsoft Dependency Injection extensions for SEQ

This project produces a NuGet URL. Visit at https://www.nuget.org/packages/Teqit.Extensions.Seq/.

Use this package during your start-up to write logging to SEQ.

It comes with a lot of enrichments by default:

• environment name,
• environment username,
• machine name,
• process Id,
• process name,
• thread Id,
• thread name.

By running the bare minimum of this package the log events will be sent as verbose to http://localhost:5341 without api key.

Example

The default extension method acccepts nullable parameters, and thus can be used without any parameters.

using Teqit.Extensions.Seq;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSeq();

If you have SEQ running on a specific URL and port, then specify it like so:

using Teqit.Extensions.Seq;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSeq("https://company.io:5341/");

If you want to log only errors, then specify it like so:

using Serilog;
using Teqit.Extensions.Seq;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSeq(level: Serilog.Events.LogEventLevel.Error);

If you want to use an API key, then specify it like so:

using Teqit.Extensions.Seq;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSeq(apiKey: "01234567890123456789");

Add the following to your built WebApplication object if you want request logging to appear in SEQ:

using Serilog;
using Teqit.Extensions.Seq;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSeq();

var app = builder.Build();
app.UseSerilogRequestLogging();

If you have SEQ running as a Docker container and want to use the default host.docker.internal URL, then specify it like so:

using Teqit.Extensions.Seq;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSeq(useDefaultDockerContainerUrl: true);
