QoS (Quality of Service) parameters play a key role in
selecting Grid resources and optimizing resources usage
efficiently. Although many works have focused on using
QoS metrics, surprisingly few tools support the monitoring
and analysis of QoS metrics of Grid services. This paper
presents a novel framework which supports the monitoring
and analysis of QoS metrics in the Grid. Our approach is
that, firstly, we develop a classification of important QoS
metrics for Grid services that should be monitored and analyzed.
Secondly, sensors are developed to monitor QoS of
disparate Grid services by using a peer-to-peer Grid monitoring
middleware. The dependencies among Grid services
are modeled. Based on that, several techniques are used to
analyze QoS metrics of dependent Grid services.
