The program needs read access to the queue # directories and queue files, so it must run as the superuser or # the \fBmail_owner\fR specified in \fBmain.cf\fR (typically # \fBpostfix\fR). # # Options: # .IP \fB-s\fR # 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. # .IP \fB-p\fR # Generate aggregate statistics for parent domains. Top level domains # are not shown, nor are domains with fewer than \fImin_subdomains\fR # subdomains. The names of parent domains are shown with a leading dot, # (e.g. \fI.example.com\fR). # .IP "\fB-m \fImin_subdomains\fR" # When used with the \fB-p\fR option, sets the minimum subdomain count # needed to show a separate line for a parent domain. The default is 5. # .IP "\fB-b \fIbucket_count\fR" # The age distribution is broken up into a sequence of geometrically # 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. # .IP "\fB-t \fIbucket_time\fR" # 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. # .IP "\fB-l\fR" # Instead of using a geometric age sequence, use a linear age sequence, # in other words simple multiples of \fBbucket_time\fR. # # This feature is available in Postfix 2.2 and later. # .IP "\fB-w \fIterminal_width\fR" # The output is right justified, with the counts for the last # bucket shown on the 80th column, the \fIterminal_width\fR 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 specified # 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. # .IP "\fB-N \fIbatch_msg_count\fR" # 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 deferred queue is large. The # default is to show intermediate results every 1000 messages. # .IP "\fB-n \fIbatch_top_domains\fR" # When reporting intermediate or final results to a termainal, report # only the top "batch_top_domains" domains. The default limit is 20 # domains. # .IP "\fB-c \fIconfig_directory\fR" # The \fBmain.cf\fR configuration file is in the named directory # instead of the default configuration directory. # .PP # Arguments: # .IP \fIqueue_name\fR # By default \fBqshape\fR displays the combined distribution of # the incoming and active queues. 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 \fBmain.cf\fR \fBqueue_directory\fR parameter setting. # While \fBmain.cf\fR supports the use of \fI$variable\fR expansion # in the definition of the \fBqueue_directory\fR parameter, the # \fBqshape\fR program does not. If you must use variable expansions # in the \fBqueue_directory\fR setting, you must specify an explicit # absolute path for each queue subdirectory even if you want the # default incoming and active queue distribution. # SEE ALSO # mailq(1), List all messages in the queue. # QSHAPE_README Examples and background material. # FILES # $config_directory/main.cf, Postfix installation parameters. # $queue_directory/maildrop/, local submission directory. # $queue_directory/incoming/, new message queue. # $queue_directory/hold/, messages waiting for tech support. # $queue_directory/active/, messages scheduled for delivery. # $queue_directory/deferred/, messages postponed for later delivery. # LICENSE # .ad # .fi # The Secure Mailer license must be distributed with this software. # AUTHOR(S) # Victor Duchovni # Morgan Stanley #-- use strict; use IO::File; use File::Find; use Getopt::Std; my $cls; # Clear screen escape sequence my $batch_msg_count; # Interim result frequency my $batch_top_domains; # Interim result count my %opts; # Command line switches my %q; # domain counts for queues and buckets my %sub; # subdomain counts for parent domains my $now = time; # reference time my $bnum = 10; # deferred queue bucket count my $width = 80; # screen char width my $dwidth = 18; # min width of domain field my $tick = 5; # minutes my $minsub = 5; # Show parent domains with at least $minsub subdomains my @qlist = qw(incoming active); do { local $SIG{__WARN__} = sub { warn "$0: $_[0]" unless exists($opts{"h"}); die "Usage: $0 [ -s ] [ -p ] [ -m <min_subdomains> ] [ -l ]\n".
