tests Coverage Status

A wrapper for other Serilog sinks. Matches when message has already been logged. Useful if having an aggressive logger, and wants to throttle the output.

Getting started

Install from NuGet:
Install-Package Serilog.Extensions.WhenRepeated 

Minimal example

// At this example duplicated messages are written as as dot
private static readonly MessageTemplate RepeatedMessageTemplate = new MessageTemplate(new MessageTemplateParser().Parse(".").Tokens);

new LoggerConfiguration()
    configureWrappedSink: x => x.Async(y => y.File("/path/to/log.txt")),
    options: new WhenRepeatedOptions(
      onRepeat: (current, previous) =>
        return new LogEvent(
          timestamp: current.Timestamp,
          level: current.Level,
          exception: null,
          messageTemplate: RepeatedMessageTemplate,
          properties: Array.Empty<LogEventProperty>());


The WhenRepeatedOptions type constructor exposes the following members.

Name Description
onRepeat Action to be taken when filter matches.
compare Statement of that how to compare current log with previous log event.
timeout Duration after which message if duplicated will be logged.
firstStrategy Strategy that determines how to handle first (not duplicated) log event.


Enrich Serilog events with repeated messages count property.

new LoggerConfiguration()
  .Enrich.WithRepeatedMessagesCount("repeatCount") // Set name under which property will be available
    configureWrappedSink: x => x.Async(y => y.File("/path/to/log.txt")),
    options: new WhenRepeatedOptions() // Default options, needed to enable counting. By default increment repeated messages count when same message occurs in 10 seconds time interval.
logger.Information(messageTemplate: "{repeatCount}");
