Writing out SourceContext

[Michael DeMond]

Hello All,

I am having problems getting the SourceContext to emit properly based on parameter position.

If I do this:

logger.Information( "{Time:ss':'fff} ({Since:ss':'fff}): {Event} {SourceContext}", tracker.Time, tracker.Mark(), @event )

The SourceContext emits as expected.

However, if I do this:

logger.Information( "{Time:ss':'fff} ({Since:ss':'fff}): {SourceContext} {Event}", tracker.Time, tracker.Mark(), null, @event )

or this:

logger.Information( "{Time:ss':'fff} ({Since:ss':'fff}): {SourceContext} {Event}", tracker.Time, tracker.Mark(), @event )

This does not emit as expected.

Is there a way to emit the SourceContext as I am trying to do here?  Or is the only way to get it to work as expected is by the first example?

Thank you,

Michael

Hi Michael,

Are you using one of the Console or File sinks? If so, they accept an outputTemplate: parameter that you can specify custom formatting in for all events (the logger methods like Information() expect a 1:1 mapping between template parameters and arguments).

Log.Logger = new LoggerConfiguration()
    .WriteTo.ColoredConsole(outputTemplate:
        "{Timestamp:HH:mm} [{Level}] ({SourceContext}) {Message}{NewLine}{Exception}")
    .CreateLogger();

Let me know if you need more info.

Regards,

Nick

Hmmm... yeah, that might be part of the problem here.  I am using my own "recording" sink that captures LogEvents and then plays them back at a later time to the ITestOutputHelper in xUnit.  xUnit's ITestOutputHelper is not available at the time that I am writing messages so I am storing them.  It would be nice to have some sort of "placeholder" token I can supply in my arguments that would enable Serilog to look it up somehow.  Maybe a new feature request? :)

Thank you,

Michael
