+<b>NAME</b>
+ qshape - Print Postfix queue domain and age distribution
+
+<b>SYNOPSIS</b>
+ <b>qshape</b> [<b>-s</b>] [<b>-p</b>] [<b>-m</b> <i>min</i><b>_</b><i>subdomains</i>]
+ [<b>-b</b> <i>bucket</i><b>_</b><i>count</i>] [<b>-t</b> <i>bucket</i><b>_</b><i>time</i>]
+ [<b>-l</b>] [<b>-w</b> <i>terminal</i><b>_</b><i>width</i>]
+ [<b>-N</b> <i>batch</i><b>_</b><i>msg</i><b>_</b><i>count</i>] [<b>-n</b> <i>batch</i><b>_</b><i>top</i><b>_</b><i>domains</i>]
+ [<b>-c</b> <i>config</i><b>_</b><i>directory</i>] [<i>queue</i><b>_</b><i>name</i> ...]
+
+<b>DESCRIPTION</b>
+ The <b>qshape</b> program helps the administrator understand the Postfix queue
+ message distribution in time and by sender domain or recipient domain.
+ The program needs read access to the queue directories and queue files,
+ so it must run as the superuser or the <b><a href="postconf.5.html#mail_owner">mail_owner</a></b> specified in <a href="postconf.5.html"><b>main.cf</b></a>
+ (typically <b>postfix</b>).
+
+ Options:
+
+ <b>-s</b> Display the sender domain distribution instead of the recipient
+ domain distribution. By default the recipient distribution is
+ displayed. There can be more recipients than messages, but as
+ each message has only one sender, the sender distribution is a
+ message distribution.
+
+ <b>-p</b> Generate aggregate statistics for parent domains. Top level
+ domains are not shown, nor are domains with fewer than <i>min</i><b>_</b><i>sub-</i>
+ <i>domains</i> subdomains. The names of parent domains are shown with a
+ leading dot, (e.g. <i>.example.com</i>).
+
+ <b>-m</b> <i>min</i><b>_</b><i>subdomains</i>
+ When used with the <b>-p</b> option, sets the minimum subdomain count
+ needed to show a separate line for a parent domain. The default
+ is 5.
+
+ <b>-b</b> <i>bucket</i><b>_</b><i>count</i>
+ The age distribution is broken up into a sequence of geometri-
+ cally increasing intervals. This option sets the number of
+ intervals or "buckets". Each bucket has a maximum queue age that
+ is twice as large as that of the previous bucket. The last
+ bucket has no age limit.
+
+ <b>-t</b> <i>bucket</i><b>_</b><i>time</i>
+ The age limit in minutes for the first time bucket. The default
+ value is 5, meaning that the first bucket counts messages
+ between 0 and 5 minutes old.
+
+ <b>-l</b> Instead of using a geometric age sequence, use a linear age
+ sequence, in other words simple multiples of <b>bucket_time</b>.
+
+ This feature is available in Postfix 2.2 and later.
+
+ <b>-w</b> <i>terminal</i><b>_</b><i>width</i>
+ The output is right justified, with the counts for the last
+ bucket shown on the 80th column, the <i>terminal</i><b>_</b><i>width</i> can be
+ adjusted for wider screens allowing more buckets to be displayed
+ without truncating the domain names on the left. When a row for
+ a full domain name and its counters does not fit in the speci-
+ fied number of columns, only the last 17 bytes of the domain
+ name are shown with the prefix replaced by a '+' character.
+ Truncated parent domain rows are shown as '.+' followed by the
+ last 16 bytes of the domain name. If this is still too narrow to
+ show the domain name and all the counters, the terminal_width
+ limit is violated.
+
+ <b>-N</b> <i>batch</i><b>_</b><i>msg</i><b>_</b><i>count</i>
+ When the output device is a terminal, intermediate results are
+ shown each "batch_msg_count" messages. This produces usable
+ results in a reasonable time even when the <a href="QSHAPE_README.html#deferred_queue">deferred queue</a> is
+ large. The default is to show intermediate results every 1000
+ messages.
+
+ <b>-n</b> <i>batch</i><b>_</b><i>top</i><b>_</b><i>domains</i>
+ When reporting intermediate or final results to a termainal,
+ report only the top "batch_top_domains" domains. The default
+ limit is 20 domains.
+
+ <b>-c</b> <i>config</i><b>_</b><i>directory</i>
+ The <a href="postconf.5.html"><b>main.cf</b></a> configuration file is in the named directory instead
+ of the default configuration directory.
+
+ Arguments:
+
+ <i>queue</i><b>_</b><i>name</i>
+ By default <b>qshape</b> displays the combined distribution of the
+ incoming and <a href="QSHAPE_README.html#active_queue">active queues</a>. To display a different set of
+ queues, just list their directory names on the command line.
+ Absolute paths are used as is, other paths are taken relative to
+ the <a href="postconf.5.html"><b>main.cf</a> <a href="postconf.5.html#queue_directory">queue_directory</a></b> parameter setting. While <a href="postconf.5.html"><b>main.cf</b></a>
+ supports the use of <i>$variable</i> expansion in the definition of the
+ <b><a href="postconf.5.html#queue_directory">queue_directory</a></b> parameter, the <b>qshape</b> program does not. If you
+ must use variable expansions in the <b><a href="postconf.5.html#queue_directory">queue_directory</a></b> setting, you
+ must specify an explicit absolute path for each queue subdirec-
+ tory even if you want the default <a href="QSHAPE_README.html#incoming_queue">incoming</a> and <a href="QSHAPE_README.html#active_queue">active queue</a> dis-
+ tribution.
