Cloud Computing, one of the emerging trends provides IT services through virtualized resources to its tenants and charges them on the basis of resource utilization. Due to lack of transparency in the activities taking place on the virtual machines at service provider's end and various security issues, users hesitate to move their infrastructure to Cloud. The users do not have a clear idea of what they are being charged for. In order to get the required information, users can track the activities on their virtual machines by using third party network monitoring tools. However these tools hog a significant amount of memory which affects the performance of other critical processes running on the VMs. Hence, we propose LUCID, a solution for monitoring network activity of VMs.

LUCID will reside in Dom0 which is a controller OS of Xen Hypervisor, leading to centralized monitoring of multiple VM's. LUCID provides kernel level packet capture mechanism and archiving of the captured data. Efficient Indexing Mechanism has been built to facilitate faster retrieval of this data when queried. The results are presented to the user via a SaaS interface (Software as a Service) where user can specify various queries and view corresponding results. This data helps the users to monitor network activity and also view the recorded traffic which provides the much needed transparency regarding network activity especially during the dormant period. Hence the user gets a clear idea of what he is being charged for.
