The RollingFile.outputTemplate that I am using for my sink in <appSettings> configuration is as below:
<add key="serilog:write-to:RollingFile.outputTemplate" value="{Timestamp:HH:mm:ss} [{Level}] {Message}{NewLine}{Exception}" />
The output log I am getting as:
19:55:10 [Information] Application_Start...
However, I want to also output the Class Name (source) from where the Log was generated, like -
19:55:10 [Information] [Global.asax.cs] Application_Start...
What should I add to the "value"? I added [Source] but is not working.
value="{Timestamp:HH:mm:ss} [{Level}] [Source?] {Message}{NewLine}{Exception}"
The property name is called SourceContext - so:
value="{Timestamp:HH:mm:ss} [{Level}] [{SourceContext}] {Message}{NewLine}{Exception}"
