This is the first of three chapters in which I am going to show you how to build a simple distributed monitoring system. In the first part, I demonstrate building a monitoring server component. This component is responsible for sending the queries to all monitoring agents, scheduling the requests, and storing the collected data in the local database. This chapter will discuss three topics: data modeling, interprocess communication, and multithreaded programming. In the data modeling section we will looks at some database design and modeling methods. Later we'll investigate the XML-RPC protocol and the Python libraries that support it. Finally we are going to look at multithreaded programming with Python.
