Abstract: The present subject matter relates to perform proactive monitoring and diagnostics in storage area networks (SANs). In one implementation, the method comprises depicting topology of the SAN in a graph, wherein the graph designates the devices as nodes, the connecting elements as edges, and depicts operations associated with at least one component of the nodes and edges. The method further comprises monitoring at least one parameter indicative of performance of the component to ascertain degradation of the at least one component and identifying, a hinge in the data associated with the monitoring, wherein the hinge is indicative of an initiation in degradation of the component. Based on the hinge, proactive diagnostics is preformed to compute a remaining lifetime of the at least one component. Thereafter, a notification is generated for an administrator of the SAN based on the remaining lifetime.
