Abstract : This paper addresses the problem of using monitoring for keeping track of user activity within a large-scale distributed storage system. We focus on the case of BlobSeer, a system designed to store massive data, while leveraging a large-scale deployment and heavy data-access concurrency. We discuss the useful data that should be collected by the monitoring tools in order to present the user with a detailed and meaningful image of the storage system and of the data inside. We propose a distributed architecture for storing and processing the received data. Moreover, we analyze the types of protocol breaches that are specific to BlobSeer and we propose a mechanism that identifies the malicious users who attempt this kind of attacks. We implement our solution as a new BlobSeer component that does not interfere with its efficient data-access primitives, but instead it builds on the user-activity history to obtain real-time information about the users in the system and possibly block those with malicious intentions.
