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!

Using PyMonitor
Sample 1

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 ())
