  my $rotatelogs = File::RotateLogs->new(
      logfile => '/path/to/access_log.%Y%m%d%H%M',
      linkname => '/path/to/access_log',
      rotationtime => 3600,
      maxage => 86400, #1day
  );

DESCRIPTION

File::RotateLogs is utility for file logger. Supports logfile rotation and makes symlink to newest logfile.

CONFIGURATION

logfile

This is file name pattern. It is the pattern for filename. The format is POSIX::strftime(), see also POSIX.

linkname

Filename to symlink to newest logfile. default: none

rotationtime

default: 86400 (1day)

maxage

Maximum age of files (based on mtime), in seconds. After the age is surpassed, files older than this age will be deleted. Optional. Default is undefined, which means unlimited. old files are removed at a background unlink worker.

sleep_before_remove

Sleep seconds before remove old log files. default: 3 If sleep_before_remove == 0, files are removed within plack processes. Does not fork background unlink worker.

offset

The number of seconds offset form UTC. default: 0 If offset is omitted or set zero, UTC is used. When rotationtime is 24h and offset is 0, log is going to be rotated at 0 O'clock (UTC). For example, to use local timezone in the zone UTC +9 (Asia/Tokyo), set 32400 (9*60*60).
