# Perl script to generate statistics from one or more Exim log files.

# Usage: eximstats [&lt;options&gt;] &lt;log file&gt; &lt;log file&gt; ...

# 1996-05-21: Ignore lines not starting with valid date/time, just in case
#               these get into a log file.
# 1996-11-19: Add the -h option to control the size of the histogram,
#               and optionally turn it off.
#             Use some Perl 5 things; it should be everywhere by now.
#             Add the Perl -w option and rewrite so no warnings are given.
#             Add the -t option to control the length of the &quot;top&quot; listing.
#             Add the -ne, -nt options to turn off errors and transport
#               information.
#             Add information about length of time on queue, and -q&lt;list&gt; to
#               control the intervals and turn it off.
#             Add count and percentage of delayed messages to the Received
#               line.
#             Show total number of errors.
#             Add count and percentage of messages with errors to Received
#               line.
#             Add information about relaying and -nr to suppress it.
# 1997-02-03  Merged in some of the things Nigel Metheringham had done:
#               Re-worded headings
#               Added received histogram as well as delivered
#               Added local senders' league table
#               Added local recipients' league table
# 1997-03-10  Fixed typo &quot;destinationss&quot;
#             Allow for intermediate address between final and original
#               when testing for relaying
#             Give better message when no input
# 1997-04-24  Fixed bug in layout of error listing that was depending on
#               text length (output line got repeated).
# 1997-05-06  Bug in option decoding when only one option.
#             Overflow bug when handling very large volumes.
# 1997-10-28  Updated to handle revised log format that might show
#               HELO name as well as host name before IP number
# 1998-01-26  Bugs in the function for calculating the number of seconds
#               since 1970 from a log date
# 1998-02-02  Delivery to :blackhole: doesn't have a T= entry in the log
#               line; cope with this, thereby avoiding undefined problems
#             Very short log line gave substring error
# 1998-02-03  A routed delivery to a local transport may not have &lt;&gt; in the
#               log line; terminate the address at white space, not &lt;
# 1998-09-07  If first line of input was a =&gt; line, $thissize was undefined;
#               ensure it is zero.
# 1998-12-21  Adding of $thissize from =&gt; line should have been adding $size.
#             Oops. Should have looked more closely when fixing the previous
#               bug!
# 1999-11-12  Increased the field widths for printed integers; numbers are
#               bigger than originally envisaged.
# 2001-03-21  Converted seconds() routine to use Time::Local, fixing a bug
#               whereby seconds($timestamp) - id_seconds($id) gave an
#               incorrect result.
#             Added POD documentation.
#             Moved usage instructions into help() subroutine.
#             Added 'use strict' and declared all global variables.
#             Added '-html' flag and resultant code.
#             Added '-cache' flag and resultant code.
#             Added add_volume() routine and converted all volume variables
#               to use it, fixing the overflow problems for individual hosts
#               on large sites.
#             Converted all volume output to GB/MB/KB as appropriate.
#             Don't store local user stats if -nfl is specified.
#             Modifications done by: Steve Campbell (&lt;steve@computurn.com&gt;)
# 2001-04-02  Added the -t_remote_users flag. Steve Campbell.
# 2001-10-15  Added the -domain flag. Steve Campbell.
# 2001-10-16  Accept files on STDIN or on the command line. Steve Campbell.
# 2001-10-21  Removed -domain flag and added -bydomain, -byhost, and -byemail.
#             We now generate our main parsing subroutine as an eval statement
#             which improves performance dramatically when not all the results
#             are required. We also cache the last timestamp to time conversion.
#
#             NOTE: 'Top 50 destinations by (message count|volume)' lines are
#             now 'Top N (host|email|domain) destinations by (message count|volume)'
#             where N is the topcount. Steve Campbell.
#
# 2001-10-30  V1.16 Joachim Wieland.
#            Fixed minor bugs in add_volume() when taking over this version
#               for use in Exim 4: -w gave uninitialized value warnings in
#               two situations: for the first addition to a counter, and if
#               there were never any gigabytes, thereby leaving the $gigs
#               value unset.
#             Initialized $last_timestamp to stop a -w uninitialized warning.
#             Minor layout tweak for grand totals (nitpicking).
#             Put the IP addresses for relaying stats in [] and separated by
#               a space from the domain name.
#             Removed the IPv4-specific address test when picking out addresses
#               for relaying. Anything inside [] is OK.
#
# 2002-07-02  Philip Hazel
#             Fixed &quot;uninitialized variable&quot; message that occurred for relay
#               messages that arrived from H=[1.2.3.4] hosts (no name shown).
#               This bug didn't affect the output.
#
# 2002-04-15  V1.17 Joachim Wieland.
#             Added -charts, -chartdir. -chartrel options which use
#             GD::Graph modules to create graphical charts of the statistics.
#
# 2002-04-15  V1.18 Steve Campbell.
#             Added a check for $domain to to stop a -w uninitialized warning.
#             Added -byemaildomain option.
#             Only print HTML header links to included tables!
#
# 2002-08-02  V1.19 Steve Campbell.
#             Changed the debug mode to dump the parser onto STDERR rather
#             than STDOUT. Documented the -d flag into the help().
#             Rejoined the divergent 2002-04-15 and 2002-07-02 releases.
#
# 2002-08-21  V1.20 Steve Campbell.
#             Added the '-merge' option to allow merging of previous reports.
#             Fixed a missing semicolon when doing -bydomain.
#             Make volume charts plot the data gigs and bytes rather than just bytes.
#             Only process log lines with $flag =~ /&lt;=|=&gt;|-&gt;|==|\*\*|Co/
#             Converted Emaildomain to Edomain - the column header was too wide!
#             This changes the text output slightly. You can revert to the old
#             column widths by changing $COLUMN_WIDTHS to 7;
#
# 2002-09-04  V1.21 Andreas J Mueller
#             Local deliveries domain now defaults to 'localdomain'.
#             Don't match F=&lt;From&gt; when looking for the user.
#
# 2002-09-05  V1.22 Steve Campbell
#             Fixed a perl 5.005 incompatibility problem ('our' variables).
#
# 2002-09-11  V1.23 Steve Campbell
#             Stopped -charts option from throwing errors on null data.
#             Don't print out 'Errors encountered' unless there are any.

# 2002-10-21  V1.23a Philip Hazel - patch from Tony Finch put in until
#               Steve's eximstats catches up.
#             Handle log files that include the timezone after the timestamp.
#             Switch to assuming that log timestamps are in local time, with
#               an option for UTC timestamps, as in Exim itself.
#
# 2003-02-05  V1.24 Steve Campbell
#             Added in Sergey Sholokh's code to convert '&lt;' and '&gt;' characters
#             in HTML output. Also added code to convert them back with -merge.
#             Fixed timestamp offsets to convert to seconds rather than minutes.
#             Updated -merge to work with output files using timezones.
#             Added caching to speed up the calculation of timezone offsets.
#
# 2003-02-07  V1.25 Steve Campbell
#             Optimised the usage of mktime() in the seconds subroutine.
#             Removed the now redundant '-cache' option.
#             html2txt() now explicitly matches HTML tags.
#             Implemented a new sorting algorithm - the top_n_sort() routine.
#             Added Danny Carroll's '-nvr' flag and code.
#
# 2003-03-13  V1.26 Steve Campbell
#             Implemented HTML compliance changes recommended by Bernard Massot.
#             Bug fix to allow top_n_sort() to handle null keys.
#             Convert all domains and edomains to lowercase.
#             Remove preceding dots from domains.
#
# 2003-03-13  V1.27 Steve Campbell
#             Replaced border attributes with 'border=1', as recommended by
#             Bernard Massot.
#
# 2003-06-03  V1.28 John Newman
#             Added in the ability to skip over the parsing and evaluation of
#             specific transports as passed to eximstats via the new &quot;-nt/.../&quot;
#             command line argument.  This new switch allows the viewing of
#             not more accurate statistics but more applicable statistics when
#             special transports are in use (ie; SpamAssassin).  We need to be
#             able to ignore transports such as this otherwise the resulting
#             local deliveries are significantly skewed (doubled)...
#
# 2003-11-06  V1.29 Steve Campbell
#             Added the '-pattern &quot;Description&quot; &quot;/pattern/&quot;' option.
#
# 2004-02-17  V1.30 Steve Campbell
#             Added warnings if required GD::Graph modules are not available or
#             insufficient -chart* options are specified.
#
# 2004-02-20  V1.31 Andrea Balzi
#             Only show the Local Sender/Destination links if the tables exist.
#
# 2004-07-05  V1.32 Steve Campbell
#             Fix '-merge -h0' divide by zero error.
#
# 2004-07-15  V1.33 Steve Campbell
#             Documentation update - I've converted the subroutine
#             documentation from POD to comments.
#
# 2004-12-10  V1.34 Steve Campbell
#             Eximstats can now parse syslog lines as well as mainlog lines.
#
# 2004-12-20  V1.35 Wouter Verhelst
#             Pie charts by volume were actually generated by count. Fixed.
#
# 2005-02-07  V1.36 Gregor Herrmann / Steve Campbell
#             Added average sizes to HTML Top tables.
#
# 2005-04-26  V1.37 Frank Heydlauf
#             Added -xls and the ability to specify output files.
#
# 2005-04-29  V1.38 Steve Campbell
#             Use FileHandles for outputting results.
#             Allow any combination of xls, txt, and html output.
#             Fixed display of large numbers with -nvr option
#             Fixed merging of reports with empty tables.
#
# 2005-05-27  V1.39 Steve Campbell
#             Added the -include_original_destination flag
#             Removed tabs and trailing whitespace.
#
# 2005-06-03  V1.40 Steve Campbell
#             Whilst parsing the mainlog(s), store information about
#             the messages in a hash of arrays rather than using
#             individual hashes. This is a bit cleaner and results in
#             dramatic memory savings, albeit at a slight CPU cost.
#
# 2005-06-15  V1.41 Steve Campbell
#             Added the -show_rt&lt;list&gt; flag.
#             Added the -show_dt&lt;list&gt; flag.
#
# 2005-06-24  V1.42 Steve Campbell
#             Added Histograms for user specified patterns.
#
# 2005-06-30  V1.43 Steve Campbell
#             Bug fix for V1.42 with -h0 specified. Spotted by Chris Lear.
#
# 2005-07-26  V1.44 Steve Campbell
#             Use a glob alias rather than an array ref in the generated
#             parser. This improves both readability and performance.
#
# 2005-09-30  V1.45 Marco Gaiarin / Steve Campbell
#             Collect SpamAssassin and rejection statistics.
#             Don't display local sender or destination tables unless
#             there is data to show.
#             Added average volumes into the top table text output.
#
# 2006-02-07  V1.46 Steve Campbell
#             Collect data on the number of addresses (recipients)
#             as well as the number of messages.
#
# 2006-05-05  V1.47 Steve Campbell
#             Added 'Message too big' to the list of mail rejection
#             reasons (thanks to Marco Gaiarin).
#
# 2006-06-05  V1.48 Steve Campbell
#             Mainlog lines which have GMT offsets and are too short to
#             have a flag are now skipped.
#
# 2006-11-10  V1.49 Alain Williams
#             Added the -emptyok flag.
#
# 2006-11-16  V1.50 Steve Campbell
#             Fixes for obtaining the IP address from reject messages.
#
# 2006-11-27  V1.51 Steve Campbell
#             Another update for obtaining the IP address from reject messages.
#
# 2006-11-27  V1.52 Steve Campbell
#             Tally any reject message containing SpamAssassin.
#
# 2007-01-31  V1.53 Philip Hazel
#             Allow for [pid] after date in log lines
#
# 2007-02-14  V1.54 Daniel Tiefnig
#             Improved the '($parent) =' pattern match.
#
# 2007-03-19  V1.55 Steve Campbell
#             Differentiate between permanent and temporary rejects.
#
# 2007-03-29  V1.56 Jez Hancock
#             Fixed some broken HTML links and added missing column headers.
#
# 2007-03-30  V1.57 Steve Campbell
#             Fixed Grand Total Summary Domains, Edomains, and Email columns
#             for Rejects, Temp Rejects, Ham, and Spam rows.
#
# 2007-04-11  V1.58 Steve Campbell
#             Fix to get &lt;&gt; and blackhole to show in edomain tables.
#
# 2007-09-20  V1.59 Steve Campbell
#             Added the -bylocaldomain option
#
# 2007-09-20  V1.60 Heiko Schlittermann
#             Fix for misinterpreted log lines

# 2013-01-14  V1.61 Steve Campbell
#             Watch out for senders sending &quot;HELO [IpAddr]&quot;

=back

=head2 Options:

=over 4

=item B&lt;-h&gt;I&lt;number&gt;

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.

=item B&lt;-ne&gt;

Don't display error information.

=item B&lt;-nr&gt;

Don't display relaying information.

=item B&lt;-nr&gt;I&lt;/pattern/&gt;

Don't display relaying information that matches.

=item B&lt;-nt&gt;

Don't display transport information.

=item B&lt;-nt&gt;I&lt;/pattern/&gt;

Don't display transport information that matches

=item B&lt;-q&gt;I&lt;list&gt;

List of times for queuing information single 0 item suppresses.

=item B&lt;-t&gt;I&lt;number&gt;

Display top &lt;number&gt; sources/destinations
default is 50, 0 suppresses top listing.

=item B&lt;-tnl&gt;

Omit local sources/destinations in top listing.

=item B&lt;-t_remote_users&gt;

Include remote users in the top source/destination listings.

=item B&lt;-include_original_destination&gt;

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.

=item B&lt;-show_dt&gt;I&lt;list&gt;

Show the delivery times (B&lt;DT&gt;)for all the messages.

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

I&lt;list&gt; is an optional list of times. E.g. -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.

=item B&lt;-show_rt&gt;I&lt;list&gt;

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.

I&lt;list&gt; is an optional list of times. E.g. -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.

=item B&lt;-byhost&gt;

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

=item B&lt;-bydomain&gt;

Show results by sending domain.
May be combined with B&lt;-byhost&gt; and/or B&lt;-byemail&gt; and/or B&lt;-byedomain&gt;.

=item B&lt;-byemail&gt;

Show results by sender's email address.
May be combined with B&lt;-byhost&gt; and/or B&lt;-bydomain&gt; and/or B&lt;-byedomain&gt;.

=item B&lt;-byemaildomain&gt; or B&lt;-byedomain&gt;

Show results by sender's email domain.
May be combined with B&lt;-byhost&gt; and/or B&lt;-bydomain&gt; and/or B&lt;-byemail&gt;.

=item B&lt;-pattern&gt; I&lt;Description&gt; I&lt;/Pattern/&gt;

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

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


=item B&lt;-merge&gt;

This option allows eximstats to merge old eximstat reports together:

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

=over 4

=item *

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

=item *

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

=item *

When merging reports, some loss of accuracy may occur in the top I&lt;n&gt; lists.
This will be towards the ends of the lists.

=item *

The order of items in the top I&lt;n&gt; lists may vary when the data volumes
round to the same value.

=back

=item B&lt;-charts&gt;

Create graphical charts to be displayed in HTML output.
Only valid in combination with I&lt;-html&gt;.

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

=over 4

=item GD

=item GDTextUtil

=item GDGraph

=back

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

 perl Makefile.PL
 make
 make test
 make install

=item B&lt;-chartdir&gt;I &lt;dir&gt;

Create the charts in the directory &lt;dir&gt;

=item B&lt;-chartrel&gt;I &lt;dir&gt;

Specify the relative directory for the &quot;img src=&quot; tags from where to include
the charts

=item B&lt;-emptyok&gt;

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.

=item B&lt;-d&gt;

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!

=head1 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 (B&lt;-help&gt;) to learn
about how to create charts from the tables.

=head1 AUTHOR

There is a website at https://www.exim.org - this contains details of the
mailing list exim-users@exim.org.

=head1 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 :)

eximstats Version $VERSION

Usage:
  eximstats [Output] [Options] mainlog1 mainlog2 ...
  eximstats -merge -html [Options] report.1.html ... &gt; weekly_rep.html

Examples:
  eximstats -html=eximstats.html mainlog1 mainlog2 ...
  eximstats mainlog1 mainlog2 ... &gt; report.txt

Parses exim mainlog or syslog files and generates a statistical analysis
of the messages processed.

Valid output types are:
-txt[=&lt;file&gt;]   plain text (default unless no other type is specified)
-html[=&lt;file&gt;]  HTML
-xls[=&lt;file&gt;]   Excel
With no type and file given, defaults to -txt and STDOUT.

Valid options are:
-h&lt;number&gt;      histogram divisions per hour. The default is 1, and
                0 suppresses histograms. Other valid values are:
                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
-nvr            don't do volume rounding. Display in bytes, not KB/MB/GB.
-t&lt;number&gt;      display top &lt;number&gt; sources/destinations
                default is 50, 0 suppresses top listing
-tnl            omit local sources/destinations in top listing
-t_remote_users show top user sources/destinations from non-local domains
-q&lt;list&gt;        list of times for queuing information. -q0 suppresses.
-show_rt&lt;list&gt;  Show the receipt times for all the messages.
-show_dt&lt;list&gt;  Show the delivery times for all the messages.
                &lt;list&gt; is an optional list of times in seconds.
                Eg -show_rt1,2,4,8.

-include_original_destination   show both the final and original
                destinations in the results rather than just the final ones.

-byhost         show results by sending host (default unless bydomain or
                byemail is specified)
-bydomain       show results by sending domain.
-byemail        show results by sender's email address
-byedomain      show results by sender's email domain
-bylocaldomain  show results by local domain

-pattern &quot;Description&quot; /pattern/
                Count lines matching specified patterns and show them in
                the results. It can be specified multiple times. Eg:
                -pattern 'Refused connections' '/refused connection/'

-merge          merge previously generated reports into a new report

-charts         Create charts (this requires the GD::Graph modules).
                Only valid with -html.
-chartdir &lt;dir&gt; Create the charts' png files in the directory &lt;dir&gt;
-chartrel &lt;dir&gt; Specify the relative directory for the &quot;img src=&quot; tags
                from where to include the charts in the html file
                -chartdir and -chartrel default to '.'

-emptyok        It is OK if there is no valid input, don't print an error.

-d              Debug mode - dump the eval'ed parser onto STDERR.
