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 (<steve@computurn.com>) # 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 "uninitialized variable" 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 =~ /<=|=>|->|==|\*\*|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=<From> 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 '<' and '>' 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 "-nt/.../" # 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 "Description" "/pattern/"' 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<list> flag. # Added the -show_dt<list> 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 <> 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 "HELO [IpAddr]" # # # For documentation on the logfile format, see # http://www.exim.org/exim-html-4.50/doc/html/spec_48.html#IX2793 =head1 NAME eximstats - generates statistics from Exim mainlog or syslog files. =head1 SYNOPSIS eximstats [Output] [Options] mainlog1 mainlog2 ... eximstats -merge [Options] report.1.txt report.2.txt ... > weekly_report.txt =head2 Output: =over 4 =item B<-txt> Output the results in plain text to STDOUT. =item B<-txt>=I<filename> Output the results in plain text.

Filename '-' for STDOUT is accepted. =item B<-xls> Output the results in Excel compatible Format to STDOUT. Requires the Spreadsheet::WriteExcel CPAN module. =item B<-xls>=I<filename> Output the results in Excel compatible format. Filename '-' for STDOUT is accepted. =back =head2 Options: =over 4 =item B<-h>I<number> 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<-ne> Don't display error information. =item B<-nr> Don't display relaying information. =item B<-nr>I</pattern/> Don't display relaying information that matches. =item B<-nt> Don't display transport information. =item B<-nt>I</pattern/> Don't display transport information that matches =item B<-q>I<list> List of times for queuing information single 0 item suppresses. =item B<-t>I<number> Display top <number> sources/destinations default is 50, 0 suppresses top listing. =item B<-tnl> Omit local sources/destinations in top listing. =item B<-t_remote_users> Include remote users in the top source/destination listings. =item B<-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. =item B<-show_dt>I<list> Show the delivery times (B<DT>)for all the messages. Exim must have been configured to use the +deliver_time logging option for this option to work. I<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. =item B<-show_rt>I<list> 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<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. =item B<-byhost> Show results by sending host. This may be combined with B<-bydomain> and/or B<-byemail> and/or B<-byedomain>. If none of these options are specified, then B<-byhost> is assumed as a default. =item B<-bydomain> Show results by sending domain. May be combined with B<-byhost> and/or B<-byemail> and/or B<-byedomain>. =item B<-byemail> Show results by sender's email address. May be combined with B<-byhost> and/or B<-bydomain> and/or B<-byedomain>. =item B<-byemaildomain> or B<-byedomain> Show results by sender's email domain. May be combined with B<-byhost> and/or B<-bydomain> and/or B<-byemail>. =item B<-pattern> I<Description> I</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/' =item B<-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 =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<n> lists. This will be towards the ends of the lists. =item * The order of items in the top I<n> lists may vary when the data volumes round to the same value. =back =item B<-charts> Create graphical charts to be displayed in HTML output. Only valid in combination with I<-html>. 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<-chartdir>I <dir> Create the charts in the directory <dir> =item B<-chartrel>I <dir> Specify the relative directory for the "img src=" tags from where to include the charts =item B<-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. =item B<-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! =back =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<-help>) 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.
