Logging and profiling meaning of %q{2}

Hi Community,

While configuring logging options in Jira Software recent versions (7.1.9 and latest) to prepare and test migration on referenced JIRA instance, We face an unknown log4j pattern in the default log4j.properties file ship with JIRA Software (Zip packages for standalone).

Extract (line 62) of log4j.properties is :

log4j.appender.filelog.layout.ConversionPattern=%d %t %p %X{jira.username} %X{jira.request.id} %X{jira.request.assession.id} %X{jira.request.ipaddr} %X{jira.request.url} [%q{2}] %m%n

Apache log4j documentation has no reference of [%q{2}] pattern (https://logging.apache.org/log4j/2.x/manual/layouts.html#PatternLayout).\\

Can one please explain that pattern or point out a web link to a reference where the meaning and the description of this pattern ?

Thank you for reading and helping me.

milliseconds as decimal I believe

Thank you Boris for your answer but it seems to be more like a custom pattern as nor Log4j neither SLF4j use the %q char.
