Yep, that would give you one logfile every day. It will not care about whether it reached 500mb though. But on the plus side that gives you a trivial way to identify which file holds a specific date, which is pretty cumbersome otherwise.

CLASSIFICATION: UNCLASSIFIED Hello, So here's what currently is configured in our .conf file:
destination syslog { file("/var/log/syslog.log" perm(0644)); };
what you are saying, is if I want logs to rotate on daily basis, I can just make the above line to read as following:
destination syslog { file("/var/log/syslog-${YEAR}-${MONTH}-${DAY}.log"); };
Thanks Jitesh Amin

syslog-ng does not support size-based rotation, you'll have to configure logrotate for that. See the packaging/debian/syslog-ng-core.syslog-ng.logrotate[1] file for an example.
[1]: Caution-https://github.com/balabit/syslog-ng/blob/master/ packaging/debian/syslog-ng-core.syslog-ng.logrotate
With logrotate, the most recent logfile syslog-ng writes to will always be syslog.log, and the rotated files will have different names - depending on the logrotate configuration you use.
For time-based, daily rotation, you can use templates in the destination filename, such as:
destination d_syslog { file("/var/log/syslog-${YEAR}-${MONTH}-${DAY}.log"); };
Hope this helps!
