Serilog

Serilog is a diagnostic logging library for .NET applications. Serilog’s support for structured logging shines when instrumenting complex, distributed, and asynchronous applications and systems

• Serilog is built from the ground up to record structured event data
• Serilog thinks in terms of log events, not log messages. An event is made up of:
  • A timestamp recording when the event happened
  • A level describing when the event should be captured
  • A message documenting what the event represents
  • Named properties describing the event
  • Possibly an Exception object
  • Log output sample:
    • console: 11:33:01 [INF] Hello, Serilog!
    • JSON : {"@t":"2017-11-20T11:33:01.22138","@m":"Hello, Serilog!"}
• Behind the scenes, logging statements in your application create LogEvent objects, while the sinks attached to the pipeline figure out how to record them.
• On LogEvents, properties added through enrichment appear the same as properties originating from the message template

Overview of Serilog

• ILogger interface
  • Logging methods

• LoggerConfiguration
  • Creates logger
  • https://github.com/serilog/serilog/blob/dev/src/Serilog/LoggerConfiguration.cs
• Log
  • Static class (an optional static entry point)
  • Log.Logger: static property public static ILogger Logger { get; set; }
  • Log.<StaticMethod>() : to log
  • Log.Logger = new LoggerConfiguration().....CreateLogger();
