NAME
Apache::Status - Embedded interpreter status information
SYNOPSIS
<Location /perl-status> SetHandler perl-script PerlHandler Apache::Status </Location>
DESCRIPTION
The Apache::Status module provides some information about the status of the Perl interpreter embedded in the server. Configure like so: <Location /perl-status> SetHandler perl-script PerlHandler Apache::Status </Location> 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 \@strings; #return an array ref } ) if Apache->module("Apache::Status"); #only if Apache::Status is loaded WARNING: Apache::Status must be loaded before these modules via the PerlModule or PerlRequire directives.
OPTIONS
StatusOptionsAll This single directive will enable all of the options described below. PerlSetVar StatusOptionsAll On StatusDumper 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 StatusPeek With this option On and the Apache::Peek module installed, functions and variables can be viewed ala Devel::Peek style: PerlSetVar StatusPeek On StatusLexInfo With this option On and the B::LexInfo module installed, subroutine lexical variable information can be viewed. PerlSetVar StatusLexInfo On StatusDeparse With this option On and B::Deparse version 0.59 or higher (included in Perl 5.005_59+), subroutines can be "deparsed". PerlSetVar StatusDeparse On Options can be passed to B::Deparse::new like so: PerlSetVar StatusDeparseOptions "-p -sC" See the B::Deparse manpage for details. StatusTerse With this option On, text-based op tree graphs of subroutines can be displayed, thanks to B::Terse. PerlSetVar StatusTerse On StatusTerseSize With this option On and the B::TerseSize module installed, text- based op tree graphs of subroutines and their size can be displayed. See the B::TerseSize docs for more info. PerlSetVar StatusTerseSize On StatusTerseSizeMainSummary With this option On and the B::TerseSize module installed, a "Memory Usage" will be added to the Apache::Status main menu. This option is disabled by default, as it can be rather cpu intensive to summarize memory usage for the entire server. It is strongly suggested that this option only be used with a development server running in -X mode, as the results will be cached. PerlSetVar StatusTerseSizeMainSummary On StatusGraph 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. Dot Location of the dot program for StatusGraph, if other than /usr/bin or /usr/local/bin GraphDir Directory where StatusGraph should write it's temporary image files. Default is $ServerRoot/logs/b_graphs
PREREQUISITES
