How to log json inside json at correct format

Question

In log4net.config file i am having the following appender.

    

I was using JsonLogging appender for logging using log4net.  If i try to log json string then json is logged like string not as an json. How can i handle this scenario ? The message inside message attribute contains json as string. I want to log that as json. 

<appender name="JsonLogging" type="log4net.Appender.RollingFileAppender">
       <file value="E:\\april.log" />
      <appendToFile value="true" />
      <staticLogFileName value="true" />
      <rollingStyle value="Date" />
      <datePattern value="'_'yyyy_MM_dd"/>
      <PreserveLogFileNameExtension value="true" />
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <layout type="log4net.Layout.SerializedLayout, log4net.Ext.Json">
        <decorator type="log4net.Layout.Decorators.StandardTypesDecorator, log4net.Ext.Json" />
        <default />
        <remove value="message" />
        <remove value="ndc"/>     
        <member value="message:messageobject"/>
      </layout>
    </appender>

{
	   "date":"2019-04-02T13:17:02.6719961+05:30",
	   "level":"INFO",
	   "appname":"Test.exe",
	   "logger":"Test.Program",
	   "thread":"1",
	   "message":{
		  "message":"{\"Consumer\":{\"os\":\"Microsoft Windows\",\"Test\":\"test\",\"name\":null,\"machine\":\"testmachine\"}}",
		  "customer":"Customername"
	   }
	}
	

private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
	log.Info(message(jsonstring));

	
	public static object message(object msg)
	{
		return new { message = msg, customer = CustomerName };
	}

Hi AishwaryaKasi,

Thank you for posting here.

For your question, you could log4net.Ext.Json to create json log.

You could download from the NuGet.

Hi Wendy Zang ,

Thanks for the reply. Actually i was using  log4net.Layout.SerializedLayout, log4net.Ext.Json to log in json format.  Actually the issue was  message inside the message attribute in the example i was posted in that ,

"message":"{\"Consumer\"  contains double quotes around json value this was the issue i am facing . How can i log json as json not as an string .

Hi AishwaryaKasi,

Thank you for feedback.

The data you provided is correct format of json. 

How do you define the log4net layout? Like the link below?

I do not test. But if you do not want the double quote, change the type.

Best Regards,

Wendy
