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:


That issue is a four years old boy now.

I found a link on Stack Overflow (
which lead me to the following link:


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.
