Restrict to level

[josephwoodward]

Hi,

What's the best approach to restricting a log to a certain level? I see RollingFile has a restrictToMinimumLevel parameter, but if I wish to restrict the log data to only errors then I can't see this being an option. I recall there being a filter API which seems like it would be the next best thing.

Alternatively could you see much value in having a restrictToLevel property available on the method?

Hi Joseph, this should work for you:

Log.Logger = new LoggerConfiguration()
    .WriteTo.Logger(lc => lc
        .Filter.ByIncludingOnly(evt => evt.Level == LogEventLevel.Error)
        .WriteTo.RollingFile("errors.txt"))
    .WriteTo.Logger(lc => lc
        .Filter.ByIncludingOnly(evt => evt.Level == LogEventLevel.Warning)
        .WriteTo.RollingFile("warnings.txt"))
    .CreateLogger();

How's that fit? Cheers!

Nice, that should do it! On a side note, do you have any up for grabs issues that are suitable for someone new to Serilog? I'd love to contribute if I could, Serilog is an awesome library!

Great, thanks for the interest!

There are a lot of repositories spread around the organisation with a few up-for-grabs item in there.

If you're interested in Linux and Win 10, I think serilog-archive/serilog-sinks-literate#9 would be a fun one?
