Method and system for extracting information from networked devices using multiple implementations of protocol access functions

摘要

A method, system, and computer program product for extracting, using a selected communication protocol, information related to a monitored device communicatively coupled to a network. The method includes retrieving, from a first memory, implementation identifiers, each of which identifies (1) a first access function configured to access the monitored device using the selected communication protocol to obtain vendor and model information of the monitored device, and (2) a second access function configured to access the monitored device using the selected communication protocol to obtain status information of the monitored device; selecting an implementation identifier among the plurality of implementation identifiers; and accessing the device using the selected communication protocol and the first access function associated with the selected implementation identifier to attempt to obtain vendor and model information related to the device. In addition, if the vendor and model information was obtained from the device, the method stores, in association with the obtained vendor and model information in a second memory, the selected implementation identifier.
