Serilog console logging with JsonFromatter

[rajurh]

I have been trying to use Serilog Console logging with JsonFormatter. When I enable option for console logging in code with .NET core we have option with JsonFromatter to renderMessage= true in its constructor which helps to render message and template in a nicer way and working well.

When I try to define and make it work using appsetting.json configuration for console logging I dont see an option to define "renderMessage" = true due to which when it logs in console I am not getting rendered message.

"formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog"

As part of configuration setting if you could let me know how to enable render message option will be of great help.

Hi! To do this, install the Serilog.Formatting.Compact package, and use Serilog.Formatting.Compact.RenderedCompactJsonFormatter instead. HTH!

Hi, I didn't use RenderedCompactJson or CompactJsonFormatter because of following reason Either of them doesn't provide both Message template and Rendered message until you define output message template which I wanted to avoid. What will be your recommendations

Hi! Just grabbing the source for CompactJsonFormatter and adding the @m field using the extra line in RenderedCompactJsonFormatter will do the job - the source is very, very short - it's easier to copy/modify than for us to support a wide variety of flags/options in the formatters. Hope this helps!

I also would like to be able to use the JsonFormatter and set "renderMessage" = true through appsettings.json.

For those wondering, this is how you configure this after the 3.3.0 release:

{
  "Name": "File",
  "Args": {
    "path": "log.json",
    "rollingInterval": "Day",
    "retainedFileCountLimit": 7,
    "formatter": {
      "type": "Serilog.Formatting.Json.JsonFormatter, Serilog",
      "renderMessage": true
    }
  }
}
