On the Impact of Management Instrumentation Models on Web Server Performance: A JMX Case Study

International audienceJMX (Java Management eXtension) is a Java framework that allows any Java technology-based application or accessible resource to become easily manageable. This standard begins to be widely used within different managed systems which vary from large mainframes to small mobile devices, limited in both resource and computing capacity. Today, little is known about the costs associated with the manageability of a system. In this paper, we analyse the impact of various instrumentation models on the behavior of both the functional and the management plane. We show on a JMX instrumented web server that the service is highly affected by the management activity in driver and component models while a daemon approach limits the management impact on the functional service
