1. A network manager system for managing a data storage network, comprising:
- one or more processors;
memory operatively coupled to said one or more processors;
program instructions in said memory for programming said one or more processors to perform network manager operations, said operations comprising;
performing a discovery agent capability determination that determines discovery capabilities of two or more discovery agents in said data storage network;
detecting, prior to discovery execution, whether a discovery capability overlap condition exists wherein said discovery capabilities are overlapping due to some of said agents being capable of discovering the same information from the same network device;
computing agent discovery assignments prior to discovery execution based on said discovery agent capability determination and according to whether a discovery overlap condition exists;
collectively, said agent discovery assignments being computed as a subset of said agent discovery capabilities in response to said discovery capability overlap condition being detected to reduce overlapping discovery;
said agent discovery assignments being based on an input listing of said discovery agents, the network devices they are capable of discovering and a cost to discover each network device, and an output listing of said discovery agents and the network devices said discovery agents are assigned to discover;
said agent discovery assignments being further based on an entity-sorting computation that produces an entity-sorting listing that associates each network device and one or more discovery agents each having a cost to discover that network device, said listing ordering said network devices according to the discovery costs of the associated discovery agents; and
said agent discovery assignments being further based on an agent-sorting computation that produces an agent-sorting listing that modifies said entity-sorting listing to order the discovery agents associated with each network device according to one or more of agent cost, load factor and agent identifier.

Abstract
A system, method and computer program product for intelligent discovery of network information from multiple information gathering agents adapted to discover information concerning the network. The discovery agents each have an associated discovery capability. Based on consideration of the agent discovery capabilities, discovery assignments are computed and network discovery is performed according to the assignments so as to reduce discovery poll overhead.
