A quick help would help me a lot......

NAME
Log::Log4perl::NDC - Nested Diagnostic Context
DESCRIPTION
Log::Log4perl allows loggers to maintain global thread-specific data, called the Nested Diagnostic Context (NDC).
At some point, the application might decide to push a piece of data onto the NDC stack, which other parts of the application might want to
reuse. For example, at the beginning of a web request in a server, the application might decide to push the IP address of the client onto
the stack to provide it for other loggers down the road without having to pass the data from function to function.
The Log::Log4perl::Layout::PatternLayout class even provides the handy %x placeholder which is replaced by the blank-separated list of
elements currently on the stack.
This module maintains a simple stack which you can push data on to, query what's on top, pop it off again or delete the entire stack.
Its purpose is to provide a thread-specific context which all Log::Log4perl loggers can refer to without the application having to pass
around the context data between its functions.
Since in 5.8.0 perl's threads don't share data only upon request, global data is by definition thread-specific.
Log::Log4perl::NDC->push($text);
Push an item onto the stack. If the stack grows beyond the defined limit ($Log::Log4perl::NDC::MAX_SIZE), just the topmost element will
be replated.
This is typically done when a context is entered.
Log::Log4perl::NDC->pop();
Discard the upmost element of the stack. This is typically done when a context is left.
my $text = Log::Log4perl::NDC->get();
Retrieve the content of the stack as a string of blank-separated values without disrupting the stack structure. Typically done by %x.
If the stack is empty the value "[undef]" is being returned.
Log::Log4perl::NDC->remove();
Reset the stack, remove all items.
Please note that all of the methods above are class methods, there's no instances of this class.
