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 \@s; #return an array ref
}
) if Apache->module("Apache::Status"); #only if Apache::Status is loaded
OPTIONS
- 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
- 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
