NAME Logmonster - log utility for merging, sorting, and processing web logs SYNOPSIS logmonster.pl -i [-v] [-r] [-n] [-b N] Interval is one of: hour (last hour) day (yesterday) month (last month) Optional: -v verbose - lots of status messages -n dry run - do everything except feed the logs into the processor -r report - last periods hit counts -b N back N days - use with -i day to process logs older than one day USAGE To see what it will do without actually doing anything /usr/local/sbin/logmonster -i day -v -n From cron: 5 1 * * * /usr/local/sbin/logmonster -i day From cron with a report of activity: 5 1 * * * /usr/local/sbin/logmonster -i day -v DESCRIPTION Logmonster is a tool to collect log files from one or many web servers, split them based on the virtual host they were served for, sort the logs into cronological order, and pipe the sorted logs to a log file analyzer. Webalizer, http-analyze, and AWstats are currently supported. MOTIVATION Log collection: I have several web sites that are mirrored. I only care agreggate statistics. To accomplish that, the logs must be collected from each server. Sorting: Since most log processors require the log file entries to be in chronological order, simply concatenating them, or feeding them one after another does not work. Logmonster sorts all the log entries for each vhost into chronological order. Agnostic: If I want to switch to another log processor, it is simple and painless. Each domain can have a preferred processor. FEATURES * Log Retrieval from one or many hosts * Ouputs to webalizer, http-analyze, and AWstats. * Automatic vhost detection Logmonster generates config files as required (ie, awstats.example.com.conf). * Efficient Reads directly from compressed log files to minimize network and disk usage. Skips sorting if you only have logs from a single host. * Flexible update intervals runs monthly, daily, or hourly * Reporting logs an activity report and sends an email friendly report. * Reliable When something goes wrong, it provides useful error messages. INSTALLATION Step 1 - Download and install (it's FREE!) https://www.tnpi.net/cart/index.php?crn=210&rn=385&action=show_detai l Install like typical perl modules: perl Makefile.PL make test make install To install the config file, 'make conf' or 'make newconf'. The newconf target will overwrite any existing config file. Step 2 - Edit logmonster.conf vi /usr/local/etc/logmonster.conf Step 3 - Edit your web servers config Apache Adjust the CustomLog and ErrorLog definitions. We make two changes, appending %v (the vhost name) to the CustomLog and adding cronolog to automatically rotate the log files. LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %v" combined CustomLog "| /usr/local/sbin/cronolog /var/log/apache/%Y/%m/%d/access.log" combined ErrorLog "| /usr/local/sbin/cronolog /var/log/apache/%Y/%m/%d/error.log" Lighttpd accesslog.format = "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %v" accesslog.filename = "|/usr/local/sbin/cronolog /var/log/http/%Y/%m/%d/access.log" server.errorlog = "/var/log/http/error.log" Step 4 - Test manually, then add to cron. crontab -u root -e 5 1 * * * /usr/local/sbin/logmonster -i day Step 5 - Read the FAQ Step 6 - Enjoy Enjoy the daily summary emails. DIAGNOSTICS Run in verbose mode (-v) to see additional status and error messages. Verbosity can be increased by appending another -v, or even (-v -v -v) maximal verbosity. If that is not enough, the source is with you. Also helpful when troubleshooting is the ability to skip cleanup (so logfiles do not have to be fetched anew) with the --noclean command line option.

Patches welcome. AUTHOR Matt Simerson (msimerson@cpan.org) ACKNOWLEDGEMENTS Gernot Hueber - sumitted the daily userlogs feature Lewis Bergman - funded authoring of several features Raymond Dijkxhoorn - suggested not sorting the files for one log host Earl Ruby - a better regexp for apache log date parsing TODO Add support for analog. Add support for individual webalizer.conf file for each domain (this will likely not happen until someone submits a diff. I don't use webalizer any more). Delete log files older than X days/months - low priority, it's easy and low maintenance to manually delete a few months log files when I'm sure I don't need them any longer. Do something with error logs (other than just compress) If files to process are larger than 10MB, find a nicer way to sort them rather than reading them all into a hash. Now I create two hashes, one with data and one with dates. I sort the date hash, and using those sorted hash keys, output the data hash to a sorted file. This is necessary as wusage and http-analyze require logs to be fed in chronological order. Look at awstats logresolvemerge as a possibility.
