ROTATELOGS(8)rotatelogsROTATELOGS(8)NAMErotatelogs - Piped logging program to rotate Apache logs
SYNOPSISrotatelogs logfile [ rotationtime [ offset ]] | [ file-
sizeM ]
SUMMARYrotatelogs is a simple program for use in conjunction with
Apache's piped logfile feature. For example:
CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
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 rota- tion time (here after 24 hours) a new log is
started.
CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
This configuration will rotate the logfile whenever it
reaches a size of 5 megabytes.
OPTIONS
logfile
The path plus basename of the logfile. If
logfile includes any '%' characters, it is
treated as a format string for strftime(3).
Otherwise, the suffix .nnnnnnnnnn is auto-
matically added and is the time in seconds.
Both formats compute the start time from the
beginning of the current period.
rotationtime
The time between log file rotations in sec-
onds.
offset 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.
filesizeM
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.
PORTABILITY
The following logfile format string substitutions should
be supported by all strftime(3) implementations, see the
strftime(3) man page for library-specific extensions.
o %A - full weekday name (localized)
o %a - 3-character weekday name (localized)
o %B - full month name (localized)
o %b - 3-character month name (localized)
o %c - date and time (localized)
o %d - 2-digit day of month
o %H - 2-digit hour (24 hour clock)
o %I - 2-digit hour (12 hour clock)
o %j - 3-digit day of year
o %M - 2-digit minute
o %m - 2-digit month
o %p - am/pm of 12 hour clock (localized)
o %S - 2-digit second
o %U - 2-digit week of year (Sunday first day of week)
o %W - 2-digit week of year (Monday first day of week)
o %w - 1-digit weekday (Sunday first day of week)
o %X - time (localized)
o %x - date (localized)
o %Y - 4-digit year
o %y - 2-digit year
o %Z - time zone name
o %% - literal `%'
