.SH "NAME"
SquidAnalyzer v4.3 \- Squid access log report generation tool
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
SquidAnalyzer parse native access log format of the Squid proxy and
generate general statistics about hits, bytes, users, networks, top
url and top second level domain.
.PP
Statistic reports are oriented to user and bandwidth control, this
is not a pure cache statistics generator. SquidAnalyzer use flat
files to store data and don't need any \s-1SQL\s0, \s-1SQL\s0 Lite or Berkeley
databases.
.PP
This analyzer is incremental so it should be run in a daily cron.
Take care if you have rotate log enable to run it before rotation
is done.
.PP
The \s-1HTML\s0 output need a huge size for large number of user. Here on
my pentium \s-1III\s0 500 MHz with 15Mb of free memory, for 600 users and
an access.log of 72 Mb it takes 20 minutes to run and generate 70 Mb
of \s-1HTML\s0 output by month. If you have an older system than this and
want to save space and time, you can disable url details feature
that logs and reports statistics for every \s-1URL\s0 and domain.
.SH "REQUIREMENT"
.IX Header "REQUIREMENT"
perl 5.005_03 or higher and the following Perl modules:
.PP
.Vb 4
\& GD
\& GD::Graph
\& GD::TextUtil
\& GD::Graph::bars3d;
.Ve
.PP
See \s-1GD\s0 and GD::Graph requirements for other needed libraries.
.PP
If they are not yet include in your \s-1OS\s0 distribution you can always find them at http://search.cpan.org/
.PP
If you have Internet access from your server, you can execute the following command to install GD::Graph::bars3d and all its dependencies.
.PP
.Vb 1
\& perl \-MCPAN \-e \*(Aqinstall GD::Graph::bars3d\*(Aq
.Ve
.PP
Images output format is \s-1PNG\s0 so libgd must be compiled with libpng.
.SH "INSTALLATION"
.IX Header "INSTALLATION"
.SS "Generic install"
.IX Subsection "Generic install"
If you want the package to be intalled into the Perl distribution just
do the following:
.PP
.Vb 3
\& perl Makefile.PL
\& make
\& make install
.Ve
.PP
Follow the instruction given at the end of install. With this default install
everything configurable will be installed under /etc/squidanalyzer. The Perl
library SquidAnalyzer.pm will be installed under your site_perl directory and
the squid-analyzer Perl script will be copied under /usr/local/bin.
.PP
The default output directory for html reports will be /var/www/squidanalyzer/.
.SS "Custom install"
.IX Subsection "Custom install"
You can create your fully customized SquidAnalyzer installation by using the
Makefile.PL Perl script. Here is a sample:
.PP
.Vb 8
\& perl Makefile.PL \e
\& LOGFILE=/var/log/squid3/access.log \e
\& BINDIR=/usr/bin \e
\& CONFDIR=/etc \e
\& HTMLDIR=/var/www/squidreport \e
\& BASEURL=/squidreport \e
\& MANDIR=/usr/man/man3 \e
\& DOCDIR=/usr/share/doc/squidanalyzer
.Ve
.PP
If you want to build a distro package, there are two other options that you may use. The \s-1QUIET\s0 option is to tell to Makefile.PL to not show the default post install \s-1README\s0. The \s-1DESTDIR\s0 is to create and install all files in a package build base directory. For example for Fedora \s-1RPM\s0, thing may look like that:
.PP
.Vb 12
\& # Make Perl and SendmailAnalyzer distrib files
\& %{_\|_perl} Makefile.PL \e
\& INSTALLDIRS=vendor \e
\& QUIET=1 \e
\& LOGFILE=/var/log/squid/access.log \e
\& BINDIR=%{_bindir} \e
\& CONFDIR=%{_sysconfdir} \e
\& BASEDIR=%{_localstatedir}/lib/%{uname} \e
\& HTMLDIR=%{webdir} \e
\& MANDIR=%{_mandir}/man3 \e
\& DOCDIR=%{_docdir}/%{uname}\-%{version} \e
\& DESTDIR=%{buildroot} < /dev/null
.Ve
.PP
See spec file in packaging/RPM for full \s-1RPM\s0 build script.
.SS "Local install"
.IX Subsection "Local install"
You can also have a custom installation. Just copy the SquidAnalyzer.pm and the
squid-analyzer perl script into a directory, copy and modify the configuration
file and run the script from here with the \-c option.
.PP
Then copy files sorttable.js, squidanalyzer.css and logo\-squidanalyzer.png into
the output directory.
.SS "Post installation"
.IX Subsection "Post installation"
1. Modify your httpd.conf to allow access to \s-1HTML\s0 output like follow:
.PP
.Vb 8
\& Alias /squidreport /var/www/squidanalyzer
\& <Directory /var/www/squidanalyzer>
\& Options \-Indexes FollowSymLinks MultiViews
\& AllowOverride None
\& Order deny,allow
\& Deny from all
\& Allow from 127.0.0.1
\& </Directory>
.Ve
.PP
2. If necessary, give additional host access to SquidAnalyzer in httpd.conf.
Restart and ensure that httpd is running.
.PP
3. Browse to http://my.host.dom/squidreport/ to ensure that things are working
properly.
.PP
4. Setup a cronjob to run squid-analyzer daily or more often:
.PP
.Vb 2
\& # SquidAnalyzer log reporting daily
\& 0 2 * * * /usr/local/bin/squid\-analyzer > /dev/null 2>&1
.Ve
.PP
or run it manually. For more information, see \s-1README\s0 file.
.PP
You can use network name instead of network ip addresses by using the
network-aliases file. Also if you don't have authentication enable and
want to replace client ip addresses by some know user or computer you
can use the user-aliases file to do so.
.PP
See the file squidanalyzer.conf to customized your output statistics and
match your network and file system configuration.
.SH "CONFIGURATION"
.IX Header "CONFIGURATION"
Unless previous version customization of SquidAnalyzer is now
done by a single configuration file squidanalyzer.conf.
.PP
Here follow the configuration directives used by Squid Analyzer.
.IP "Output output_directory" 4
.IX Item "Output output_directory"
Where SquidAnalyzer should dump all \s-1HTML\s0, data and images files.
You should give a path that can be read by a Web browser.
.IP "LogFile squid_access_log_file" 4
.IX Item "LogFile squid_access_log_file"
Set the path to the Squid log file.
.IP "NetworkAlias network\-aliases_file" 4
.IX Item "NetworkAlias network-aliases_file"
Set path to the file containing network alias name. Network are
show as Ip addresses so if you want to display name instead
create a file with this format:
.Sp
.Vb 1
\& LOCATION_NAME IP_NETWORK_ADDRESS
.Ve
.Sp
Separator must be a tabulation.
.Sp
You can use regex to match and group some network addresses. See
network-aliases file for examples.
.IP "UserAlias user\-aliases_file" 4
.IX Item "UserAlias user-aliases_file"
Set path to the file containing user alias name. If you don't have
auth_proxy enable users are seen as ip addresses. So if you want to
show username or computer name instead, create a file with this format:
.Sp
.Vb 1
\& FULL_USERNAME IP_ADDRESS
.Ve
.Sp
If you have auth_proxy enable but want to replace login name by full
user name, create a file with this format:
.Sp
.Vb 1
\& FULL_USERNAME LOGIN_NAME
.Ve
.Sp
Separator for both must be a tabulation.
.Sp
You can use regex to match and group some user login or ip addresses. See
user-aliases file for examples.
.IP "AnonymizeLogin 0" 4
.IX Item "AnonymizeLogin 0"
Set this to 1 if you want to anonymize all user login. The username
will be replaced by an unique id that change at each squid-analyzer
