Apache::Status - Embedded interpreter status information
<Location /perl-status> SetHandler perl-script PerlHandler Apache::Status </Location>
The Apache::Status module provides some information about the status of the Perl interpreter embedded in the server.
Configure like so:
Other modules can "plugin" a menu item like so:
Apache::Status->menu_item( 'DBI' => "DBI connections", #item for Apache::DBI module sub { my($r,$q) = @_; #request and CGI objects my(@strings); push @strings, "blobs of html"; return \@s; #return an array ref } ) if Apache->module("Apache::Status"); #only if Apache::Status is loaded
When browsing symbol tables, the values of arrays, hashes ans calars can be viewed via Data::Dumper if this configuration variable is set to On:
PerlSetVar StatusDumper On
With this option On and the Apache::Peek module installed, functions and variables can be viewed ala Devel::Peek style:
PerlSetVar StatusPeek On
When StatusDumper is enabled, another link "OP Tree Graph" will be present with the dump if this configuration variable is set to On:
PerlSetVar StatusGraph
This requires the B module (part of the Perl compiler kit) and B::Graph (version 0.03 or higher) module to be installed along with the dot program.
Dot is part of the graph visualization toolkit from AT&T: http://www.research.att.com/sw/tools/graphviz/).

WARNING: Some graphs may produce very large images, some graphs may produce no image if B::Graph's output is incorrect.
Location of the dot program for StatusGraph, if other than /usr/bin or /usr/local/bin
Directory where StatusGraph should write it's temporary image files. Default is $ServerRoot/logs/b_graphs
The Devel::Symdump module, version 2.00 or higher.
