CGI::Application::Plugin::DBIProfile(3pm) User Contributed Perl Documentation CGI::Application::Plugin::DBIProfile(3pm)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).
