Serilog.Sinks.PeriodicBatching

A wrapper for Serilog sinks that asynchronously emits events in batches, useful when logging to a slow and/or remote target.

[!IMPORTANT] Serilog 4.x and later versions support batching natively. New projects should use Serilog's IBatchedLogEventSink and WriteTo.Sink(IBatchedLogEventSink), not this package which is now only maintained for compatibility reasons.

Getting started

Sinks that, for performance reasons, need to emit events in batches, can be implemented using PeriodicBatchingSink from this package.

First, install the package into your Sink project:

dotnet add package Serilog.Sinks.PeriodicBatching

Then, instead of implementing Serilog's ILogEventSink, implement IBatchedLogEventSink in your sink class:

class ExampleBatchedSink : IBatchedLogEventSink
{
    public async Task EmitBatchAsync(IEnumerable<LogEvent> batch)
    {
        foreach (var logEvent in batch)
            Console.WriteLine(logEvent);
    }
    
    public Task OnEmptyBatchAsync() { }
}

Finally, in your sink's configuration method, construct a PeriodicBatchingSink that wraps your batched sink:

public static class LoggerSinkExampleConfiguration
{
    public static LoggerConfiguration Example(this LoggerSinkConfiguration loggerSinkConfiguration)
    {
        var exampleSink = new ExampleBatchedSink();
        
        var batchingOptions = new PeriodicBatchingSinkOptions
        {
            BatchSizeLimit = 100,
            Period = TimeSpan.FromSeconds(2),
            EagerlyEmitFirstEvent = true,
            QueueLimit = 10000
        };
        
        var batchingSink = new PeriodicBatchingSink(exampleSink, batchingOptions);
        
        return loggerSinkConfiguration.Sink(batchingSink);
    }
}
