Is it possible to rotate logs for every 5 minutes

For example instead of using

${HOST}_${R_YEAR}${R_MONTH}${R_DAY}${R_HOUR}${R_MIN}.log I want to use ${HOST}_${R_YEAR}${R_MONTH}${R_DAY}${R_HOUR}${R_MIN%5}.log (which rotates every 5 minues )

Depends on what version of syslog-ng you're using. With 3.3 and earlier, you can't, not without patching or very ugly hacks. With 3.4, you can do something like this: ${HOST}_${R_YEAR}${R_MONTH}${R_DAY}${R_HOUR}$(/ ${R_MIN} 5).log $(/ X Y) will divide X with Y, and truncate, so it will rotate every 5 minutes. $(% X Y) exists too, but since that returns the remainder of a division, it would write each minute into a different file (up to 5 different files). If you need it, I can port this functionality over to 3.2, it's fairly trivial. But the chances that it would be integrated into the official sources is slim to none, so until 3.4, you'd have to patch syslog-ng. An alternative - but horribly ugly - solution, that works with 3.2 is to abuse the $(if) template function somewhat like this: $(if ("${R_MIN}" < 5) "0" "$(if ("${R_MIN}" < 10) "1" "...")") I'm not going to write the whole stuff here, as it's painful already, but I hope you get the idea (take an $(if), and embed the next in the former's false branch, and return the desired filename part in the true branch). You can read more about the syntax of $(if) in the syslog-ng 3.2 documentation: http://www.balabit.com/sites/default/files/documents/syslog-ng-ose-v3.2-guid... Come to think of it, you could even do it with filters! But I rarely use filters, so if you want to go down this path, I'm unable to provide a working example. But it seems possible at least. Also: I did not test the above example, so your mileage may vary. -- |8]
