  26      <p><code>rotatelogs</code> is a simple program for use in
  27      conjunction with Apache's piped logfile feature.  For example:</p>
  28
  29 <div class="example"><p><code>
  30      CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
  31 </code></p></div>
  32
  33      <p>This creates the files /var/logs/logfile.nnnn where nnnn  is
  34      the system time at which the log nominally starts (this time
  35      will always be a multiple of the rotation time, so  you  can
  36      synchronize cron scripts with it).  At the end of each rotation
  37      time (here after 24 hours) a new log is started.</p>
  38
  39 <div class="example"><p><code>
  40      CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
  41 </code></p></div>
  42
  43      <p>This configuration will rotate the logfile whenever it reaches
  44      a size of 5 megabytes.</p>
  45
  46 <div class="example"><p><code>
  47      ErrorLog "|bin/rotatelogs /var/logs/errorlog.%Y-%m-%d-%H_%M_%S 5M"
  48 </code></p></div>
  49      <p>This configuration will rotate the error logfile whenever it
  50      reaches a size of 5 megabytes, and the suffix to the logfile name
  51      will be created of the form
  52      <code>errorlog.YYYY-mm-dd-HH_MM_SS</code>.</p>

  74 <dt><code>-l</code> (<em>2.0.51 and later</em>)</dt>
  75 <dd>Causes the use of local time rather than GMT as the base for the
  76 interval. Note that using <code>-l</code> in an environment which changes the

  81 <dd>The path plus basename of the logfile.  If <var>logfile</var>
  82 includes any '%' characters, it is treated as a format string for
  83 <code>strftime(3)</code>.  Otherwise, the suffix
  84 <var>.nnnnnnnnnn</var> is automatically added and is the time in
  85 seconds.  Both formats compute the start time from the beginning of
  86 the current period.</dd>

  94 <dd>The number of minutes offset from UTC.  If omitted, zero is
  95 assumed and UTC is used.  For example, to use local time in the zone
  96 UTC -5 hours, specify a value of <code>-300</code> for this argument.</dd>
  97
  98 <dt><code><var>filesize</var>M</code></dt>
  99
 100 <dd>The maximum file size in megabytes followed by the letter

 102 in place of both rotationtime and offset.</dd>
