<div class="m_-888374457547434678moz-cite-prefix">Hello,<br>
<br>
Syslog-ng doesn't do any form of rotation - you're using macros in
the destination filenames instead. Contents of macros like $YEAR
get parsed from the timestamp of the incoming messages so as long
as messages contain older timestamps syslog-ng will (re)open files
reflecting these older timestamps and append logs there. There is
no need to restart syslog-ng as not the restart changes where logs
will get written but the metadata associated with the logs.<br>
<br>
IIRC the antique 1.6.8 version you're using also has support for
other datetime macros (prefixed with C_ or R_) which reflect the
'C'urrent or 'R'eception timestamp so you can alter the current
behaviour - although I wouldn't recommend switching for example to
$C_YEAR-$C_MONTH-$C_DAY as it could be confusing to see the last
few logs of a given day written to another file than people would
expect.<br>
<br>
Does this make sense or did I misunderstood your observation?<br>
<br>

skipping the {} made it work and I now see a syslog file

Amin> Let me ask this, with the following
config = destination<br>
Amin> syslog {
file("/var/log/syslog-${YEAR}-<wbr>${MONTH}-${DAY}.log");<br>
Amin> };<br>
<br>
Amin> It created new file and started
writing to it (versus creating<br>
Amin> new syslog.log). Question, if we plan
to accept this for now,<br>
Amin> with above config, would it create a
new file ever day with<br>
Amin> following file names or no it would
not work with v1.6.8<br>
<br>
With syslog-ng 1.6.8, it would not create a new
file every day, and<br>
would continue writing to
syslog-{YEAR}-{MONTH}-{DAY}.<wbr>log. With newer<br>
versions, it would create files like
`syslog-2018-05-30.log`. No `.0`,<br>
`.1` or the like would be appended. That's a
convention of logrotate.<br>
With syslog-ng, you get filenames that match the
template, they will<br>
have nothing appended or prepended that is not in
the filename template.<br>
