Ubuntu Manpage: CGI::Application::Plugin::DBIProfile

Provided by: libcgi-application-plugin-dbiprofile-perl_0.07-2_all

NAME

       CGI::Application::Plugin::DBIProfile - DBI profiling plugin

SYNOPSIS

           # Set env in apache or in perl.
           $ENV{DBI_PROFILE} = '2/CGI::Application::Plugin::DBIProfile::Driver';
           use CGI::Application::Plugin::DevPopup;
           use CGI::Application::Plugin::DBIProfile;

           The rest of your application follows
           ...

INSTALLATION

       To install this module, run the following commands:

           perl Makefile.PL
           make
           make test
           make install

DESCRIPTION

       CGI::Application::Plugin::DBIProfile provides popup (using CAP::DevPopup if available)
       holding DBI Profile information (see DBI::Profile, DBI::ProfileDumper). It will output
       both graphed output and a DBI::ProfileDumper report.

CONFIGURATION

To enable, set the DBI_PROFILE environment variables. For example

in apache config for cgi
SetVar DBI_PROFILE 2/CGI::Application::Plugin::DBIProfile::Driver
SetVar CAP_DBIPROFILE_EXEC 1

in apache config for mod_perl
PerlSetVar DBI_PROFILE 2/CGI::Application::Plugin::DBIProfile::Driver
PerlSetVar CAP_DBIPROFILE_EXEC 1

in your CAP module
BEGIN {
$ENV{DBI_PROFILE} = '2/CGI::Application::Plugin::DBIProfile::Driver';
$ENV{CAP_DBIPROFILE_EXEC} = 1;
}

If you disable it, be sure to unset the DBI_PROFILE env var, as it will continue to
accumulate stats regardless of the setting of CAP_DBIPROFILE_EXEC, you just won't see
them.

MODES OF OPERATION
It has two modes of opperation; per-request or per-process. In a CGI environment, there is
no difference.

per-request - this is the default.
per-process - set the following env var to a true value.
CAP_DBIPROFILE_PERPROCESS 1

Under mod_perl, the per-request setup will show the DBI Profile specific to each page hit.
The per-process setup will show the DBI Profile that has accumulated for the life of the
apache process you are hitting.

Please note, running under the per-process setting can cause your memory usage to grow
significantly, as the profile data is never cleared.

GRAPHING PLUGINS
The default graphing module is CGI::Application::Plugin::DBIProfile::Graph::HTML, which
generates a minimal inline HTML graph. To change which graphing plugin is used, it's just
another environment variable (no need to set this if you like the default).

CAP_DBIPROFILE_GRAPHMODULE Your::Graph::Module::Name

Please see CGI::Application::Plugin::DBIProfile::Graph::HTML for information on writing
new graph modules.

TODO

       Tests. None exist at this time.

       Other graphing plugins (Plotr, Open Flash Chart, GraphML using Graph::Easy).

       Add checks to be sure $dbh->{Profile} isn't disabled (probably better in ::Driver).

REQUIREMENTS

       Data::JavaScript
       IO::Scalar
       HTML::Template

       Optional:

       •   GD::Graph

           For CGI::Application::Plugin::DBIProfile::Graph::GDGraphInline support.

       •   SVG::TT::Graph

           For CGI::Application::Plugin::DBIProfile::Graph::SVGTT support.

       •   HTML::BarGraph

           For CGI::Application::Plugin::DBIProfile::Graph::HTMLBarGraph support.
