<title>rotatelogs - Piped logging program to rotate Apache logs</title>
|
|
|
|
<summary>
|
|
<p><code>rotatelogs</code> is a simple program for use in
|
|
conjunction with Apache's piped logfile feature. For example:</p>
|
|
|
|
<example>
|
|
CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
|
|
</example>
|
|
|
|
<p>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.</p>
|
|
|
|
<example>
|
|
CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
|
|
</example>
|
|
|
|
<p>This configuration will rotate the logfile whenever it reaches
|
|
a size of 5 megabytes.</p>

<dl>
|
|
|
|
<dt><code><var>logfile</var></code></dt>
|
|
|
|
<dd>The path plus basename of the logfile. If <var>logfile</var>
|
|
includes any '%' characters, it is treated as a format string for
|
|
<code>strftime(3)</code>. Otherwise, the suffix
|
|
<var>.nnnnnnnnnn</var> is automatically added and is the time in
|
|
seconds. Both formats compute the start time from the beginning of
|
|
the current period.</dd>
|
|
|
|
<dt><code><var>rotationtime</var></code></dt>
|
|
|
|
<dd>The time between log file rotations in seconds.</dd>
|
|
|
|
<dt><code><var>offset</var></code></dt>
|
|
|
|
<dd>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 <code>-300</code> for this argument.</dd>
|
|
|
|
<dt><code><var>filesize</var>M</code></dt>
|
|
|
|
<dd>The maximum file size in megabytes followed by the letter
|
|
<code>M</code> to specify size rather than time. Use this parameter
|
|
in place of both rotationtime and offset.</dd>

<p>The following logfile format string substitutions should be
|
|
supported by all <code>strftime(3)</code> implementations, see
|
|
the <code>strftime(3)</code> man page for library-specific
|
|
extensions.</p>
