Serilog RollingFile

Question

I am trying to use WriteTo.RollingFile with Serilog as the following to write one file per day:

var log = new LoggerConfiguration().WriteTo.RollingFile(                     @"F:\logs\log-{Date}.txt",                     LogEventLevel.Debug).CreateLogger();             log.Information("this is a log test"); 

But I am getting a new log file for each log entry during the same day!

How does one configure Serilog to write to a new file every day as to have a have a single log file per day?

And is there any archiving process to delete files older than 7 days?

Answer 1

Try below:

 var log = new LoggerConfiguration()           .MinimumLevel.Debug()           .WriteTo.File(@"f:\log\log.txt", rollingInterval: RollingInterval.Day)            .CreateLogger(); 

The log file name will be automatically log-20150819.txt etc. You do not need to specify the date.Old files will be cleaned up as per retainedFileCountLimit - default is 31.

Answer 2

WriteTo.RollingFile Deprecated

Since the posted answer, the method RollingFile is no longer viable and replaced with File and options to roll the logs.

Now one must use the standard Serilog.Sinks.File NuGet package which supports rolling:

.WriteTo.File(path: @"e:\logs\skilliam.log",                rollingInterval: RollingInterval.Day,               rollOnFileSizeLimit: true,                fileSizeLimitBytes: 123456);
