QSROTATE(1) qsrotate man page QSROTATE(1)NAME
qsrotate - Log rotation tool (similar to Apache's rotatelogs).
SYNOPSIS
qsrotate -o <file> [-s <sec>] [-f] [-z] [-g <num>] [-u <name>] [-p]
DESCRIPTION
qsrotate reads from stdin (piped log) and writes the data to the provided file rotating the file after the specified time.
OPTIONS -o <file>
Output log file to write the data to.
-s <sec>
Rotation interval in seconds, default are 86400 seconds.
-f Forced log rotation even no data is written.
-z Compress (gzip) the rotated file.
-g <num>
Generations (number of files to keep).
-u <name>
Become another user, e.g. www-data.
-p Writes data also to stdout (for piped logging).
EXAMPLE
TransferLog "|qsrotate -f -z -g 3 -o /dest/file -s 86400"
The name of the rotated file will be /dest/filee.YYYYmmddHHMMSS where YYYYmmddHHMMSS is the system time at which the data has been rotated.
NOTE
Each qsrotate instance must use an individual file!

ROTATELOGS(8) rotatelogs ROTATELOGS(8)NAME
rotatelogs - Piped logging program to rotate Apache logs
SYNOPSIS
rotatelogs [ -l ] [ -L linkname ] [ -p program ] [ -f ] [ -t ] [ -v ] [ -e ] [ -c ] [ -n number-of-files ] logfile rotationtime|file-
size(B|K|M|G) [ offset ]
SUMMARY
rotatelogs is a simple program for use in conjunction with Apache's piped logfile feature. It supports rotation based on a time interval or
maximum size of the log.
OPTIONS -l Causes the use of local time rather than GMT as the base for the interval or for strftime(3) formatting with size-based rotation.
-L linkname
Causes a hard link to be made from the current logfile to the specified link name. This can be used to watch the log continuously
across rotations using a command like tail -F linkname.
-p program
If given, rotatelogs will execute the specified program every time a new log file is opened. The filename of the newly opened file
is passed as the first argument to the program. If executing after a rotation, the old log file is passed as the second argument.
rotatelogs does not wait for the specified program to terminate before continuing to operate, and will not log any error code
returned on termination. The spawned program uses the same stdin, stdout, and stderr as rotatelogs itself, and also inherits the
environment.
-f Causes the logfile to be opened immediately, as soon as rotatelogs starts, instead of waiting for the first logfile entry to be read
(for non-busy sites, there may be a substantial delay between when the server is started and when the first request is handled,
meaning that the associated logfile does not "exist" until then, which causes problems from some automated logging tools)
-t Causes the logfile to be truncated instead of rotated. This is useful when a log is processed in real time by a command like tail,
and there is no need for archived data. No suffix will be added to the filename, however format strings containing '%' characters
will be respected.
-v Produce verbose output on STDERR. The output contains the result of the configuration parsing, and all file open and close actions.
-e Echo logs through to stdout. Useful when logs need to be further processed in real time by a further tool in the chain.
-c Create log file for each interval, even if empty.
-n number-of-files
Use a circular list of filenames without timestamps. With -n 3, the series of log files opened would be "logfile", "logfile.1",
"logfile.2", then overwriting "logfile". Available in 2.4.5 and later.
logfile
rotationtime
The time between log file rotations in seconds. The rotation occurs at the beginning of this interval. For example, if the rotation
time is 3600, the log file will be rotated at the beginning of every hour; if the rotation time is 86400, the log file will be
rotated every night at midnight. (If no data is logged during an interval, no file will be created.)
filesize(B|K|M|G)
The maximum file size in followed by exactly one of the letters B (Bytes), K (KBytes), M (MBytes) or G (GBytes). .PP When time and
size are specified, the size must be given after the time. Rotation will occur whenever either time or size limits are reached.
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. In most cases, -l should be used instead of specifying an offset.
EXAMPLES
CustomLog "|bin/rotatelogs /var/log/logfile 86400" common
This creates the files /var/log/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.
CustomLog "|bin/rotatelogs -l /var/log/logfile.%Y.%m.%d 86400" common
This creates the files /var/log/logfile.yyyy.mm.dd where yyyy is the year, mm is the month, and dd is the day of the month. Logging will
switch to a new file every day at midnight, local time.
CustomLog "|bin/rotatelogs /var/log/logfile 5M" common
This configuration will rotate the logfile whenever it reaches a size of 5 megabytes.
ErrorLog "|bin/rotatelogs /var/log/errorlog.%Y-%m-%d-%H_%M_%S 5M"
This configuration will rotate the error logfile whenever it reaches a size of 5 megabytes, and the suffix to the logfile name will be cre-
ated of the form errorlog.YYYY-mm-dd-HH_MM_SS.
CustomLog "|bin/rotatelogs -t /var/log/logfile 86400" common
This creates the file /var/log/logfile, truncating the file at startup and then truncating the file once per day. It is expected in this
scenario that a separate process (such as tail) would process the file in real time.
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 `%'
