Subject Re: MDC log purge
Date Tue, 14 Nov 2017 15:07:01 GMT
Hi Eric,

You combine the sift appender with a rolling file appender.

As you can see your sift appender is a FileAppender.
Instead, you can use a RollingFileAppender, with a size, backup, etc.
So, it will rotate and purge automatically.

Regards
JB
