       sarg - Squid Analysis Report Generator


       sarg [options] [logfile...]


       sarg is a log file parser and analyzer for the Squid Web Proxy Cache[1]. It allows you to
       view "where" your users are going to on the Internet.

       sarg generates reports in HTML with fields such as: users, IP Addresses, bytes, sites, and
       times. These HTML files can appear in your web server´s directory for browsing by users or
       administrators. You may also have sarg email the reports to the Squid Cache administrator.

       sarg can read squid or Microsoft ISA access logs. Optionally, it can complement the
       reports with the log of a Squid filter/redirector such as squidGuard[2].


       A summary of options is included below.

           Show summary of options.

       -a hostname|ip address
           Limits report to records containing the specified hostname/ip address

       -b filename
           Enables UserAgent log and writes it to filename.

               This option is currently unused.

       -c filename
           Read filename for a list of the web hosts to exclude from the report. See the section
           called “HOST EXCLUSION FILE”.

           Convert a squid log file date/time field to a human-readable format. All the log files
           are read and output as one text on the standard output.

           Output, on the standard output, the internal css sarg inlines in the reports. You can
           redirect the output to a file of your choice and edit it. Then you can override the
           internal css with external_css_file in sarg.conf.

           Using an external css can reduce the size of the report file. If you are short on disk
           space, you may consider exporting the css as explained above.

       -d date
           Use date to restrict the report to some date range during log file processing. Format
           for date is dd/mm/yyyy-dd/mm/yyyy or a single date dd/mm/yyyy. Date ranges can also be
           specified as day-n, week-n, or month-n where n is the number of days, weeks or months
           to jump backward. Note that there is no spaces around the hyphen.

       -e email
           Sends report to email (stdout for console).

       -f filename
           Reads configuration from filename.

       -g e|u
           Sets date format in generated reports.
               e = Europe -> dd/mm/yy
               u = USA    -> mm/dd/yy

           Generates reports by user and ip address.

               This requires the report_type option in config file to contain "users_sites".

           Don´t delete any old report. It is equivalent to setting --lastlog 0 but is provided
           for convenience.

       -l filename
           Uses filename as the input log. This option can be repeated up to 255 times to read
           multiple files. If the files end with the extension .gz, .bz2 or .Z they are
           decompressed. If the file name is just -, the log file is read from standard input. In
           that case, it cannot be compressed.

           This option is kept for compatibility with older versions of sarg but, starting with
           sarg 2.3, the log files may be named on the command line without the -l option. It
           allows the use of wildcards on the command line. Make sure you don´t exceed the limit
           of 255 files.

       --lastlog n
           Limit the number of logs kept in the output directory to n. Any supernumerary report
           is deleted starting with the oldest report. The value of n must be positive or zero. A
           value of zero means no report should be deleted.

       -L filename
           Reads a proxy redirector log file such as one created by squidGuard or Rejik. If you
           use this option, you may want to configure redirector_log_format in sarg.conf to match
           the output format of your web content filtering program. This option can be repeated
           up to 64 times to read multiple files.

           Enables ip address resolution.

       -o dir
           Writes report in dir.

           Generates reports using ip address instead of userid.

       -P prefix --splitprefix prefix
           This option must be used with --split. If it is provided, the input log is split among
           several files each containing one day. The name of the output files is made of the
           prefix and the date formated as -YYYY-MM-DD.

           The output files are written in the output directory specified with -o or in the
           current directory.

       -s string
           Limits report to the site specified by string [eg.]

           Split the squid log file and output it as text on the standard output omitting the
           dates outside of the range specified by the -d parameter. If it is combined with
           --convert the dates are also converted to a human-readable format.

           Combined with -P, the log is written in several files each containing one day of the
           original log.

       -t string
           Limits the records included in the report based on time-of-day. Format for string is
           HH:MM or HH:MM-HH:MM. The former reports only the requested time. The latter reports
           any entry falling within the requested range. This limit complement the limit imposed
           by option -d.

       -u user
           Limits reports to user activities.

       -w dir
           Store temporary files in dir. In fact, sarg stores its temporary files in the sarg
           subdirectory of dir. Be sure to set the HTML output directory to a place outside of
           the temporary directory or sarg may fail or delete the report when it completes its

           Writes process messages to stdout.


       Sarg can be told to exclude visited hosts from the report by providing it with a file
       containing one host to exclude per line. The "host" may be one of the following:

       ·   a full host name,

       ·   a host name starting with a wildcard (*) to match any prefix,

       ·   a single ip address,

       ·   a subnet noted a.b.c.d/e.

       Example 1. Example of a hosts exclusion file

       Sarg cannot exclude IPv6 addresses at the moment.
