Existing Solution
- Logging Application Block (Microsoft Enterprise Library)
- Log4net
- NLog
- Elmah
Yet Another Log Library
- March to a different tune?
- Newer is better?
- Is the icon prettier?
Why Serilog
- Structured log message
- Many sinks
- Flexible!
Structured Log Message
Simple, Scalar Values
var count = 456;
Log.Information("Retrieved {Count} records", count);- Booleans
- Numerics
- Strings
- Temporals - DateTime, DateTimeOffset, TimeSpan
- Others - Guid, Uri
- Nullables - nullable versions of any of the types above
Structured Log Message
Collections
var fruit = new[] { "Apple", "Pear", "Orange" };
Log.Information("In my bowl I have {Fruit}", fruit);Structured Log Message
Collections
var fruit = new Dictionary<string,int> {{ "Apple", 1}, { "Pear", 5 }};
Log.Information("In my bowl I have {Fruit}", fruit);Structured Log Message
Objects
var position = new { Latitude = 25, Longitude = 134 };
Log.Logger.Warning("Processed {@Position}", position);
// 02:34:23 [AppId:{ Id = 1, Name = BenBen } WRN] Processed {"Latitude": 25, "Longitude": 134}Many Sinks
There are so many sinks you can find here:
Flexible
- You can configuration settings via XML/JSON/Code
- You can use sub-loggers
- Sub-loggers + Sinks = Superpower
