And if you are using daemontools-logging, you might want to watch your
concurrency levels with mrtg as well. 

Here's a script that looks up the latest status line and reports local and
remote concurrency to mrtg:

----------------------
#!/usr/bin/perl
# qmail-mrtg-concurrency
# mrtg-script for logging qmail concurrency levels
# 1999-10-09, [EMAIL PROTECTED], http://x42.com/
# Share and enjoy

use strict;

my ($qmail_log_dir) = (@ARGV);
chop($qmail_log_dir) if $qmail_log_dir =~ m#/$#;

my ($lastfile);

opendir(DIR, $qmail_log_dir) or die;
@_ = sort readdir(DIR);
for (;;)
{
  $_ = pop(@_);
  die "No log files at all." unless $_;
  next unless s/^\@//;
  $lastfile = "$qmail_log_dir/\@$_"; 
  last;
}
closedir(DIR);

my $status = rep " status: " $lastfile | tail -1;

if ($status =~ m#local (\d+)/\d+ remote (\d+)#)
{
        print "$1\n$2\n";
}
else
{
        print "0\n\0\n";
}
