Formatter

The package always registers its internal console formatter when AddCustomLogging is used. Application code does not instantiate the formatter directly; write normal Serilog message templates and the registered logger applies the formatter to console output.

The formatter writes a timestamp, a three-letter log level, message-template text, colored property values, and exception details. Scalar values get default colors by type: strings are white, numbers are cyan, booleans are magenta, and null values are dark gray.

Usage

using Serilog;

Log.Information(
    "Processed {Count:c} items for {Application:bg} in {Elapsed:0.00|y} ms",
    42,
    "admin",
    18.742
);

Message-template property formats can include color shorthand. Use the shorthand as the property format, or combine a numeric format and color with |.

using Serilog;

Log.Information("User {UserId:y} logged in", 42);
Log.Information("Completed in {Elapsed:0.00|g} ms", 18.742);
