Python Run Time Monitor Module
Copyright (c) 2003, 2004 Jonas Widen

Abstract
PyMonitor module is used to add support for enable runtime monitoring of an Python application.

After creating an instance of the MonitorServer and starting the MonitorServer thread it publish an XML-RPC interface that provides methods for listing all current availible class instances the monitored Python instance has allocated.
For a specific class instance the MonitorServer can provide information about all it's attributes and all class attributes for the given instance.

PyMonitor is using the gc (garbage collector) module for retriving all information.

The package also includes a simple GUI client also written in Python and wxPython.

This package were developed on my spare time for making "debuging" easier when developing a large control system written complete in Python.
It is now used for all products the company I'm working for for detection of leaking instances and finding dead locks and just for see how the system is doing when we run large tests.

I'm intressed of comments and help for making this module better so please contact me on jonas.widen at esdg.se if you are intressed!

 Than you can connect to this Program by:
server = xmlrpclib.Server("http://127.0.0.1:8881")
server.listobjects('')
server.probe('Queue')
 Sample 2
import socket
my_host=socket.gethostbyname (socket.gethostname ())
import PyMonitor.monitor as Pymonitor
