The syntax is:
\begin{description}
\titem{log\_rotate\_size: N} Where N is the maximum size of a log file in bytes.
- The default value is 104857600 (10Mb).
+ The default value is 10485760 (10Mb).
+\end{description}
+
+\ejabberd{} can also rotates the log files at given date interval.
+The exact value is controlled by \term{log\_rotate\_date} option.
+The syntax is:
+\begin{description}
+ \titem{log\_rotate\_date: D} Where D is a string with syntax is taken from the syntax newsyslog uses in newsyslog.conf.
+ The default value is \term{""} (no rotation triggered by date).
\end{description}
However, you can rotate the log files manually.
-For doing this, set \term{log\_rotate\_size} option to some absurdly high value, then,
-when you need to rotate the files, rename and then reopen them.
+For doing this, set \term{log\_rotate\_size} option to 0 and \term{log\_rotate\_date}
+to empty list, then, when you need to rotate the files, rename and then reopen them.
The ejabberdctl command \term{reopen-log}
(please refer to section \ref{ectl-commands})
reopens the log files,

+## rotation: Describe how to rotate logs. Either size and/or date can trigger
+## log rotation. Setting count to N keeps N rotated logs. Setting count to 0
+## does not disable rotation, it instead rotates the file and keeps no previous
+## versions around. Setting size to X rotate log when it reaches X bytes.
+## To disable rotation set the size to 0 and the date to ""
+## Size syntax is taken from the syntax newsyslog uses in newsyslog.conf.
+## Some examples:
+## $D0 rotate every night at midnight
+## $D23 rotate every day at 23:00 hr
+## $W0D23 rotate every week on Sunday at 23:00 hr
+## $W5D16 rotate every week on Friday at 16:00 hr
+## $M1D0 rotate on the first day of every month at midnight
+## $M5D6 rotate on every 5th day of the month at 6:00 hr
+##
+log_rotate_size: 10485760
+log_rotate_date: ""
+log_rotate_count: 1
+
+##
+## overload protection: If you want to limit the number of messages per second
+## allowed from error_logger, which is a good idea if you want to weather a flood
+## of messages when system is overloaded, you can set a limit.
+## 100 is ejabberd's default.
+log_rate_limit: 100
