<h4 id="intro">Naming Conventions</h4>
|
|
<p>The <tt>ntpd</tt> includes a comprehensive monitoring facility which collects
|
|
statistical data of various types and writes the data to files associated with
|
|
each type at defined events or intervals. The files associated with a particular
|
|
type are collectively called the generation file set for that type. The files
|
|
in the file set are the members of that set.</p>
|
|
<p>File sets have names specific to the type and generation epoch. The names
|
|
are constructed from three concatenated elements <i><tt>prefix</tt></i>, <i><tt>filename</tt></i> and <i><tt>suffix</tt></i>:</p>
|
|
<dl>
|
|
<dt><i><tt>prefix</tt></i></dt>
|
|
<dd>The directory path specified in the <tt>statsdir</tt> command.</dd>
|
|
<dt><i><tt>name</tt></i></dt>
|
|
<dd>The name specified by the <tt>file</tt> option of the <tt>filegen</tt> command.</dd>
|
|
<dt><i><tt>suffix</tt></i></dt>
|
|
<dd>A string of elements bdginning with . (dot) followed by a number of elements
|
|
depending on the file set type.</dd>
|
|
</dl>
|
|
<p>Statistics files can be managed using scripts, examples of which are in the <tt>./scripts</tt> directory.
|
|
Using these or similar scripts and Unix <tt>cron</tt> jobs, the files can be
|
|
automatically summarized and archived for retrospective analysis.</p>
|

<p>Unless noted otherwise, further information about these commands is on the <a href="decode.html">Event Messages and Status Codes</a> page.</p></a> page.</p><dl>

<dt id="filegen"><tt>filegen <i>name</i> [file <i>filename</i>] [type <i>type</i>]
|
|
[link | nolink] [enable | disable]</tt></dt>
|
|
<dd>
|
|
<dl>
|
|
<dt><i><tt>name</tt></i></dt>
|
|
<dd>Specifies the file set type from the list in the next section.</dd>
|
|
<dt><tt>file <i>filename</i></tt></dt>
|
|
<dd>Specifies the filename prefix. The default is the file set type, such as "loopstats".</dd>
|
|
<dt><tt>type <i>typename</i></tt></dt>
|
|
<dd>Specifies the file set interval. The following intervals are supported
|
|
with default <tt>day</tt>:</dd>
|
|
<dd>
|
|
<dl>
|
|
<dt><tt>none</tt></dt>
|
|
<dd>The file set is actually a single plain file.</dd>
|
|
<dt><tt>pid</tt></dt>
|
|
<dd>One file set member is created for every incarnation of <tt>ntpd</tt>.
|
|
The file name suffix is the string .<tt>n</tt>, where <tt>n</tt> is the
|
|
process ID of the <tt>ntpd</tt> server process.</dd>
|
|
<dt><tt>day</tt></dt>
|
|
<dd>One file set member is created per day. A day is defined as the period
|
|
between 00:00 and 23:59 UTC. The file name suffix is the string .<tt>yyyymmdd</tt>,
|
|
where <tt>yyyy</tt> is the year, <tt>mm</tt> the month of the year and <tt>dd</tt> the
|
|
day of the month. Thus, member created on 10 December 1992 would have suffix <tt>.19921210</tt>.</dd>
|
|
<dt><tt>week</tt></dt>
|
|
<dd>One file set member is created per week. The week is defined as the
|
|
day of year modulo 7. The file name suffix is the string .<tt>yyyyWww</tt>,
|
|
where <tt>yyyy</tt> is the year, <tt>W</tt> stands for itself and <tt>ww</tt> the
|
|
week number starting from 0. For example, The member created on 10 January
|
|
1992 would have suffix <tt>.1992W1</tt>.</dd>
|
|
<dt><tt>month</tt></dt>
|
|
<dd>One file set member is created per month. The file name suffix is the
|
|
string .<tt>yyyymm</tt>, where <tt>yyyy</tt> is the year and <tt>mm</tt> the
|
|
month of the year starting from 1. For example, The member created on 10
|
|
January 1992 would have suffix <tt>.199201</tt>.</dd>
|
|
<dt><tt>year</tt></dt>
|
|
<dd>One file set member is generated per year. The file name suffix is the
|
|
string .<tt>yyyy</tt>, where <tt>yyyy</tt> is the year. For example, The
|
|
member created on 1 January 1992 would have suffix <tt>.1992</tt>.</dd>
|
|
<dt><tt>age</tt></dt>
|
|
<dd>One file set member is generated every 24 hours of <tt>ntpd</tt> operation.
|
|
The filename suffix is the string <tt>.adddddddd</tt>, where <tt>a</tt> stands
|
|
for itself and <tt>dddddddd</tt> is the <tt>ntpd</tt> running time in seconds
|
|
at the start of the corresponding 24-hour period.</dd>
|
|
</dl>
|
|
</dd>
|
|
<dt><tt>link | nolink</tt></dt>
|
|
<dd>It is convenient to be able to access the current file set members by
|
|
file name, but without the suffix. This feature is enabled by <tt>link</tt> and
|
|
disabled by <tt>nolink</tt>. If enabled, which is the default, a hard link
|
|
from the current file set member to a file without suffix is created. When
|
|
there is already a file with this name and the number of links to this file
|
|
is one, it is renamed by appending a dot, the letter <tt>C</tt>, and the
|
|
pid of the <tt>ntpd</tt> server process. When the number of links is greater
|
|
than one, the file is unlinked. This allows the current file to be accessed
|
|
by a constant name.</dd>
|
|
<dt><tt>enable | disable</tt></dt>
|
|
<dd>Enable or disable the recording function, with default <tt>enable</tt>.
|
|
These options are intended for remote configuration commands.</dd>
