21.9. Looking Inside the Server

There are a number of tools that allow you look at the server internals at runtime, through a convenient web interface.

21.9.1. Apache::Status—Embedded Interpreter Status Information

This is a very useful module. It lets you watch what happens to the Perl part of the mod_perl server. You can watch the size of all subroutines and variables, variable dumps, lexical information, opcode trees, and more.
