Method and system for extracting information from networked devices using the HTTP protocol and precondition information

摘要

A method, system, and computer program product for extracting information associated with a monitored device communicatively coupled to a network. The method includes the steps of (1) accessing a first memory to obtain access information for accessing the monitored device, the access information including a type of status information to obtain from the monitored device and precondition information used for obtaining the type of status information from the monitored device, wherein the precondition information restricts a location of the type of status information obtainable from the monitored device; (2) accessing the device using an HTTP protocol and an IP address of the monitored device to obtain an information string associated with the monitored device; (3) extracting information corresponding to the type of status information from the information string using the precondition information; and (4) storing the extracted information in association with the IP address of the monitored device.
