rotatelogs \- Piped logging program to rotate Apache logs

.SH "SUMMARY"
|
|
|
|
.PP
|
|
rotatelogs is a simple program for use in conjunction with Apache's piped logfile feature\&. For example:
|
|
|
|
.nf
|
|
|
|
CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
|
|
|
|
.fi
|
|
|
|
.PP
|
|
This creates the files /var/logs/logfile\&.nnnn where nnnn is the system time at which the log nominally starts (this time will always be a multiple of the rotation time, so you can synchronize cron scripts with it)\&. At the end of each rotation time (here after 24 hours) a new log is started\&.
|
|
|
|
.nf
|
|
|
|
CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
|
|
|
|
.fi
|
|
|
|
.PP
|
|
This configuration will rotate the logfile whenever it reaches a size of 5 megabytes\&.
|
|
|
|
.nf
|
|
|
|
ErrorLog "|bin/rotatelogs /var/logs/errorlog\&.%Y-%m-%d-%H_%M_%S 5M"
|
|
|
|
.fi
|
|
|
|
.PP
|
|
This configuration will rotate the error logfile whenever it reaches a size of 5 megabytes, and the suffix to the logfile name will be created of the form errorlog\&.YYYY-mm-dd-HH_MM_SS\&.
|
|
|
|
|
|
.SH "OPTIONS"
|
|
|
|
|
|
.TP
|
|
-l
|
|
Causes the use of local time rather than GMT as the base for the interval\&. Note that using -l in an environment which changes the GMT offset (such as for BST or DST) can lead to unpredictable results!
|
|
.TP
|
|
\fIlogfile\fR
|
|
The path plus basename of the logfile\&. If \fIlogfile\fR includes any '%' characters, it is treated as a format string for strftime(3)\&. Otherwise, the suffix \fI\&.nnnnnnnnnn\fR is automatically added and is the time in seconds\&. Both formats compute the start time from the beginning of the current period\&.
|
|
.TP
|
|
\fIrotationtime\fR
|
|
The time between log file rotations in seconds\&.
|
|
.TP
|
|
\fIoffset\fR
|
|
The number of minutes offset from UTC\&. If omitted, zero is assumed and UTC is used\&. For example, to use local time in the zone UTC -5 hours, specify a value of -300 for this argument\&.
|
|
.TP
|
|
\fIfilesize\fRM
|
|
The maximum file size in megabytes followed by the letter M to specify size rather than time\&. Use this parameter in place of both rotationtime and offset\&.
|
|
|
|
.SH "PORTABILITY"
|
|
|
|
.PP
|
|
The following logfile format string substitutions should be supported by all strftime(3) implementations, see the strftime(3) man page for library-specific extensions\&.
