Abstract
A method for diagnosing network performance problems includes providing a graph representing a topology of a network including first nodes that are classified as providers of a resource, second nodes that are classified as consumers of the resource, and third nodes that are classified as mediators intervening between the providers and the consumers. Responsively to a report of a performance problem encountered by a given consumer in the network, at least one input/output (I/O) path is traced through the graph connecting the given consumer to one or more of the providers. One or more problematic nodes are identified along the at least one I/O path as possible causes of the performance problem.
