A lightweight high performance Serilog sink that writes to SQLite database.

Install Serilog.Sinks.SQLite from NuGet

Install-Package Serilog.Sinks.SQLite

Configure logger by calling WriteTo.SQLite()

var logger = new LoggerConfiguration()
    .WriteTo.SQLite(@"Logs\log.db")
    .CreateLogger();
    
logger.Information("This informational message will be written to SQLite database");

To use the SQLite sink with the Serilog.Settings.AppSettings package, first install that package if you haven't already done so:

Install-Package Serilog.Settings.AppSettings

In your code, call ReadFrom.AppSettings()

var logger = new LoggerConfiguration()
    .ReadFrom.AppSettings()
    .CreateLogger();

In your application's App.config or Web.config file, specify the SQLite sink assembly and required sqliteDbPath under the <appSettings> node:

<appSettings>
    <add key="serilog:using:SQLite" value="Serilog.Sinks.SQLite"/>
    <add key="serilog:write-to:SQLite.sqliteDbPath" value="Logs\log.db"/>
    <add key="serilog:write-to:SQLite.tableName" value="Logs"/>
    <add key="serilog:write-to:SQLite.storeTimestampInUtc" value="true"/>
</appSettings>    

SQLite sink automatically buffers log internally and flush to SQLite database in batches on dedicated thread.
