Experimenting Middleware-Level Monitoring Facilities to Observe Component-based Applications
Eduardo Fonseca, Sand Luz Corrêa, Renato Cerqueira · 2008
As distributed component-based applications increase in size and complexity, on-line application monitoring becomes a crucial issue for assur ing quality of service. In this paper we propose a monitoring architecture built into the component system itself that allows a fine-grained observation of the resources being in use by an application. Then, we provide an evaluation of the overhead imposed by the architecture carrying out experiments and observing the resource-usage behavior of two different types of application (data-intensive and message-intensive). The results show that the monitoring cost can be very affordable.
