You can view QoSSIOC events from the NetApp Element Configuration extension point. The plug-in reports a QoSSIOC event when a VM with a QoS-enabled datastore is reconfigured or issued a power or guest event.
QoSSIOC events are displayed from locally added clusters. In a Linked Mode environment, log into the vSphere Web Client that has the cluster added locally to view QoSSIOC events for that cluster.
