You may want to make your filter more specific (e.g. add a facility or severity) because otherwise all messages from all sources that happen to have the string "HISTORY" in them anywhere will get sent to your new log file and nowhere else.

Move the history log path to the top of the list and add flags(final) to it.

That flag means "if you follow this path don't follow any others".

Hello
Everything that is written by users on console (my system is gentoo) is logged in 3 different files (debug , syslog, messages) ...
I'd like to route all history logs to one file only...
i made a filter and it works fine (it writes history to history.log) but still it writes it to those 3 files (debug , syslog, messages) as well ...
so now everything I type is written to 4 files (debug , syslog, messages and history.log) ...

is there possibility to configure syslog-ng to log history only to one file (for example history.log) and leave others files clean?

best regards
nichu

My standard configuration (with my modifiication to route history to history.log) looks like this:
