SYNOPSIS

        eximstats [Output] [Options] mainlog1 mainlog2 ...
        eximstats -merge [Options] report.1.txt report.2.txt ... > weekly_report.txt

   Output:
       -txt
           Output the results in plain text to STDOUT.

       -txt=filename
           Output the results in plain text. Filename '-' for STDOUT is accepted.

       -html
           Output the results in HTML to STDOUT.

       -html=filename
           Output the results in HTML. Filename '-' for STDOUT is accepted.

       -xls
           Output the results in Excel compatible Format to STDOUT.  Requires the
           Spreadsheet::WriteExcel CPAN module.

       -xls=filename
           Output the results in Excel compatible format. Filename '-' for STDOUT is accepted.

   Options:
       -hnumber
           histogram divisions per hour. The default is 1, and 0 suppresses histograms. Valid
           values are:

           0, 1, 2, 3, 5, 10, 15, 20, 30 or 60.

       -ne Don't display error information.

       -nr Don't display relaying information.

       -nr/pattern/
           Don't display relaying information that matches.

       -nt Don't display transport information.

       -nt/pattern/
           Don't display transport information that matches

       -qlist
           List of times for queuing information single 0 item suppresses.

       -tnumber
           Display top <number> sources/destinations default is 50, 0 suppresses top listing.

       -tnl
           Omit local sources/destinations in top listing.

       -t_remote_users
           Include remote users in the top source/destination listings.

       -include_original_destination
           Include the original destination email addresses rather than just using the final
           ones.  Useful for finding out which of your mailing lists are receiving mail.

       -show_dtlist
           Show the delivery times (DT)for all the messages.

           Exim must have been configured to use the +deliver_time logging option for this option
           to work.

           list is an optional list of times. Eg -show_dt1,2,4,8 will show the number of messages
           with delivery times under 1 second, 2 seconds, 4 seconds, 8 seconds, and over 8
           seconds.

       -show_rtlist
           Show the receipt times for all the messages. The receipt time is defined as the
           Completed hh:mm:ss - queue_time_overall - the Receipt hh:mm:ss.  These figures will be
           skewed by pipelined messages so might not be that useful.

           Exim must have been configured to use the +queue_time_overall logging option for this
           option to work.

           list is an optional list of times. Eg -show_rt1,2,4,8 will show the number of messages
           with receipt times under 1 second, 2 seconds, 4 seconds, 8 seconds, and over 8
           seconds.

       -byhost
           Show results by sending host. This may be combined with -bydomain and/or -byemail
           and/or -byedomain. If none of these options are specified, then -byhost is assumed as
           a default.

       -bydomain
           Show results by sending domain.  May be combined with -byhost and/or -byemail and/or
           -byedomain.

       -byemail
           Show results by sender's email address.  May be combined with -byhost and/or -bydomain
           and/or -byedomain.

       -byemaildomain or -byedomain
           Show results by sender's email domain.  May be combined with -byhost and/or -bydomain
           and/or -byemail.

       -pattern Description /Pattern/
           Look for the specified pattern and count the number of lines in which it appears.
           This option can be specified multiple times. Eg:

            -pattern 'Refused connections' '/refused connection/'

       -merge
           This option allows eximstats to merge old eximstat reports together. Eg:

            eximstats mainlog.sun > report.sun.txt
            eximstats mainlog.mon > report.mon.txt
            eximstats mainlog.tue > report.tue.txt
            eximstats mainlog.wed > report.web.txt
            eximstats mainlog.thu > report.thu.txt
            eximstats mainlog.fri > report.fri.txt
            eximstats mainlog.sat > report.sat.txt
            eximstats -merge       report.*.txt > weekly_report.txt
            eximstats -merge -html report.*.txt > weekly_report.html

           •   You can merge text or html reports and output the results as text or html.

           •   You can use all the normal eximstat output options, but only data included in the
               original reports can be shown!

           •   When merging reports, some loss of accuracy may occur in the top n lists.  This
               will be towards the ends of the lists.

           •   The order of items in the top n lists may vary when the data volumes round to the
               same value.

       -charts
           Create graphical charts to be displayed in HTML output.  Only valid in combination
           with -html.

           This requires the following modules which can be obtained from
           http://www.cpan.org/modules/01modules.index.html

           GD
           GDTextUtil
           GDGraph

           To install these, download and unpack them, then use the normal perl installation
           procedure:

            perl Makefile.PL
            make
            make test
            make install

           On Debian GNU/Linux you can use "apt-get install libgd-perl libgd-text-perl
           libgd-graph-perl" instead.

       -chartdirI <dir>
           Create the charts in the directory <dir>

       -chartrelI <dir>
           Specify the relative directory for the "img src=" tags from where to include the
           charts

       -emptyok
           Specify that it's OK to not find any valid log lines. Without this we will output an
           error message if we don't find any.

       -d  Debug flag. This outputs the eval()'d parser onto STDOUT which makes it easier to trap
           errors in the eval section. Remember to add 1 to the line numbers to allow for the
           title!

DESCRIPTION

       Eximstats parses exim mainlog and syslog files to output a statistical analysis of the
       messages processed. By default, a text analysis is generated, but you can request other
       output formats using flags. See the help (-help) to learn about how to create charts from
       the tables.

TO DO

       This program does not perfectly handle messages whose received and delivered log lines are
       in different files, which can happen when you have multiple mail servers and a message
       cannot be immediately delivered. Fixing this could be tricky...

       Merging of xls files is not (yet) possible. Be free to implement :)
