Abstract: An apparatus and method for monitoring and debugging interface protocols in a computer system is disclosed. A software based communication protocol logging system (CPLS) provides a single event logging interface for multiple communication protocols. A client logging interface of the CPLS is used by client components to periodically transfer log data or messages to a log file thereby providing a debug tracing log of the execution of the client component. The CPLS comprises software for supporting the calls that are members of the client logging interface. In general, the CPLS provides a generic event logging interface for one or more client components thereby insulating client components from data and methods particular to a specific communication protocol. The protocol specific information and functions are maintained within independent protocol specific event handlers. The present invention improves on the prior art systems by creating an abstraction layer (i.e.
