Serilog.Sinks.SpeedConsole

Serilog sink that writes to console with high-performance non-blocking output. Supports plaintext and JSON output but does not support themes and colors.

This sink uses a background channel with a single reader, efficient text buffer, and asynchronous writes to remove all blocking and lock contention to the console output stream. It also implements IDiposable so calling Log.CloseAndFlush() will ensure all lines are flushed.

Recommended for high-volume logging where console output is collected or redirected to another system, for example this library was originally created for large application clusters running in Kubernetes and logging hundreds of JSON objects every second.

• Built for net6.0, netstandard2.1, netstandard2.0
• Release notes here: CHANGELOG.md

Getting started

Install package from Nuget:

dotnet add package Serilog.Sinks.SpeedConsole

Configure Logger (using code):

var config = new SpeedConsoleSinkOptions { UseJson = true }; Log.Logger = new LoggerConfiguration().WriteTo.SpeedConsole(config).CreateLogger();
