Hi everyone:

I'm writing to all of you because I want to display a sequence number for each event. I've done some research regarding this and I know for sure that LogBack is not able to natively handle this as Log4j2 does with %sn, or as JUL partially does with getSequenceNumber() (I won't be changing LogBack because of this, anyway).

I know for sure LogBack is lacking this functionality because of this issue on JIRA:

http://jira.qos.ch/browse/LOGBACK-546

That issue is a four years old boy now.

I found a link on Stack Overflow (http://stackoverflow.com/questions/11162951/line-numbers-with-logback) which lead me to the following link:

http://logback.qos.ch/manual/layouts.html#customConversionSpecifier

I tried a static number but it was shared across threads so it didn't work that well. I also thought of ThreadLocal but I read a story which freaked me out:

Does anyone know of a good way to achieve sequentials?

Best regards and thanks in advance.
