Serilog - multiple log files

Question

I am using Serilog for logging and cant\' figure out how to separate log events to different files. For example, I want to log errors to error_log-ddmmyyyy.txt and warnings

Answer 1

I think you need:

.ByIncludingOnly(evt => evt.Level == LogEventLevel.Warning)

Edit:

In many cases it's now more succinct to use Serilog.Sinks.Map. With it, the example can be written as:

Log.Logger = new LoggerConfiuration()
    .WriteTo.Map(
        evt => evt.Level,
        (level, wt) => wt.RollingFile("Logs\\" + level + "-{Date}.log"))
    .CreateLogger();
