Seq Documentation and Support

Welcome to the Seq documentation hub. You'll find comprehensive guides and documentation to help you start working with Seq as quickly as possible, as well as support if you get stuck. Let's jump right in!

Get Started    

Getting Started on Windows

Download Seq .msi from datalust.co/download to install it on your local machine, or a Windows server. This pages explains installation steps, how to configure your application to send logs to Seq, enabling authentication, and next steps.

Seq is a log server that runs on a central machine. Your application uses a logging library like Serilog or Microsoft.Extensions.Logging to send structured log events to Seq's HTTP API, which stores them and makes them searchable through Seq's web interface.

1. Download the Seq installer

Download the latest Seq .msi from the Seq website.

2. Install Seq

Launching the installer will start the Setup Wizard:

Seq Setup Wizard

Step through each page of the wizard. Once the installer has finished copying files, choose to start the Seq service.

Unless you've installed Seq previously, this will open the Seq Service Administration dialog and you'll be prompted for a location to store Seq's data files, and a URL to host the user interface and HTTP API. Choose the defaults if you're unsure.

🚧

It's important to set an administrator username and password for Seq when prompted.

After the service is configured, browse the Seq UI at http://localhost:5341.

If you're hosting Seq on a shared server for your team, check out the System Requirements and Production Deployment Checklist.

3. Ingest log events

Before you can benefit from Seq, your applications need to be configured to send log events through one of the supported logging libraries.

  • Using Serilog - Serilog is a modern logging library for the .NET platform with deep support for structured event data.
  • Using ASP.NET Core - the Microsoft.Extensions.Logging library included in ASP.NET Core works well with Seq.
  • Using Node.js - on Node.js, we support the Pino, Winston, and Bunyan logging libraries.

Seq integrates with a range of languages, libraries and frameworks, and has a simple HTTP API for receiving log data. Learn more about getting logs into Seq.

If you're unsure where to start, we recommend Serilog.
