1.3 Overview

The COM+ Tracker Service Protocol enables remote clients to monitor instances of components running on a server. The server end of the protocol tracks the status of component instances and instance containers on the server and implements an interface that clients can use to poll for this status. It also optionally includes an event-driven notification system in which the client can supply (via another protocol) a callback interface for receiving tracker events. The server then calls the client's callback interface whenever new tracking data is available, for example, as a result of local events on the server.
