An event sink for Serilog that writes to the Seq event server. Distributed via NuGet.

From the NuGet Package Manager Console:

PM> Install-Package Seq.Client.Serilog

The package uses the Seq namespace:

using Seq;

Configure Serilog using the WriteTo.Seq() extension method on LoggerConfiguration:

Log.Logger = new LoggerConfiguration()
  .WriteTo.Seq("http://my-seq-server")
  .CreateLogger();

In Serilog's defaut configuration, events with Information level and above will be recorded. If you choose to increase the base logging level, e.g. to Debug, you can set the Seq sink to Information-level to prevent large volumes of network traffic:

  .WriteTo.Seq("http://my-seq-server", restrictedToMinimumLevel: LogEventLevel.Information)

The sink transmits log events to the server asynchronously to avoid heavy performance penalties. Buffered events will be flushed and any outstanding network requests will be completed when the hosting application terminates normally. If the application is terminated via an attached debugger, the task manager or as a result of hard termination such as stack overflow, events in transit may be lost.

To address this, and to prevent lost events when network or server issues prevent delivery, a buffer file set may be specified:

  .WriteTo.Seq("http://my-seq-server", bufferBaseFilename: @"C:\Logs\my-app")

This will create files of the format my-app-{Date}.jsnl, where events will be written until they can be reliably shipped to the server.
