Hi Remko,

Not sure if you noticed, old log4j has all the formatting including uuid in the tests. Raw
old log4j will take even less time.

Will try switching the tests and will let you know.

Also the RollingFileAppender will be used in production, so want to use the same for testing.

to fulfil what i am looking for.

doesn't use these methods other than for testing:

> 			String action, String desc, Result result, String reason) {
> 		String validateStatus = "";

> 			validateStatus = "event_name";

> 		} else if (!ValidateDesc(desc)) {
> 			validateStatus = "desc";
> 		} else if (!ValidateReason(result, reason)) {
> 			validateStatus = "reason";
> 		}
> 		return validateStatus;

> {code}
> Options tried:
> 1.
> * extended ExtendedLoggerWrapper
> * created the map of the Custom logger
> * This option was failing because of "writing to a closed appender"
> * Attached is the code "CustomLogger.java"
>    
> 2. Modified the AbstractLogger in Trunk and added the below methods:
> {code}
>       @Override
>     public void info(final String message) {
>     String updtMessage = message + " amexlogger_error=\"Incorrect method used\"";
>         logIfEnabled(FQCN, Level.INFO, null, updtMessage, (Throwable) null);
>     }
>  public void info(final String transactionId, final String app_name, final String event_name,
final String action, final String desc, final String result, final String reason, final String...
moreFields) { 
>        String message = "transaction_id=" + transactionId + " " + "app_name=" + app_name
+ " " + "event_name=" + event_name + " " + "action=" + action;
>  
>         logIfEnabled(FQCN, Level.INFO, null, message, (Throwable) null);
>     }
> {code}
> 	I don't want to modify the methods inside the log4j-api. 
> 	
> Please help me with the correct approach on how to use log4j2 for this usecase.
> Thanks
