Bottleneck Detection of Distributed Obiect Systems from End User's Viewpoints
Hironori Emaru, Masaharu Akatsu · IEEJ Transactions on Electronics Information and Systems · 2002
We propose a bottleneck detection method for CORBA-based distributed object systems. This method has following two features. The first one is to realize instrumentation without modifying target objects by using “interceptor” Interceptor is a function of CORBA-based distributed object systems which can intercept messages among objects. The other is to output a procedure which is executed by an end user as a sequence diagram. By using this method, we can detect performance bottlenecks from end user's viewpoints. This method can't specify a sequence uniquely in case of multiplicity of procedures on one object. In this paper, we show the multiplicity does not matter for bottleneck detection in practice.
